FamilyKe'ano Kalakaua (father)
Nani Kalakaua (mother)

RelativesKeako (uncle)
Mele (aunt, deceased)
Chin Ho Kelly (cousin)

Officer Kono Kalakaua is a fresh HPD academy graduate who was recruited by Steve for the new task force in the pilot episode. She is the cousin of Chin Ho Kelly. Despite her slight frame, she is well-versed in martial arts and is a skilled marksman (she is usually the designated sniper when the situation requires one).

Kono was a former professional surfer but a serious injury to her knee ended her career. She decides to join the "family trade" and was days away from graduating from the HPD academy when McGarrett recruited her for the new "Governor's Task Force", as Five-0 was initially called. In the first several episodes of season 1, she works under the watchful eye of her cousin and quickly wins the trust and confidence of the other team members. She is detained and questioned by the HPD, having been accused of stealing $10 million from an HPD asset forfeiture locker. While on suspension, she helps Chin and Danny go after Wo Fat, who was responsible for framing McGarrett for the murder of the Governor. To the members of the Five-0 task force and to the general public, Kono had been stripped of her badge by the Internal Affairs Department of the HPD, but it was later revealed to be a ploy for her to go undercover to bust a string of dirty ex-cops.

In Season 2, Kono began a relationship with Hiro Noshimuri's son, Adam. When Adam's brother, Michael, is released from prison, he kills someone with Kono's gun to frame her. She is cleared, but Adam has to kill Michael to protect her and Kono goes into hiding with Adam, skipping from one place to another to evade capture by vengeful yakuza members. At the beginning of Season 5, Adam starts to talk about marriage, and in the episode "Blackout" Kono accepts his proposal. They marry at the end of the season, but in the Season 6 pilot they are tortured by Chin's brother-in-law, Gabriel, who runs away with Adam's money. The money was to pay the yakuza to free Adam from his past. Without the money the yakuza's men persecute Adam and he is forced to kill them before discovering that Gabriel has paid off his debt with the yakuza. Upset, Adam goes to the police with Kono and he accords for an 18 months reclusion.

At the end of Season 7, Kono left Hawaii for Carson City, Nevada where she joined a multi-agency task force combating sex trafficking. In the season 8 episode I Ka Wa Ma Mua, I Ka Wa Ma Hope (The Future is in the Past) Danny dreams of the future and Kono has a child with Adam. However, midway through season 9, Adam returns to Hawaii and tells the team he and Kono have broken up.

RelativesDebora McGarrett (Aunt), (deceased) Steven McGarrett (Grandfather), (deceased)

Mary Ann McGarrett is the younger sister of Steve McGarrett. She, along with her brother, were both sent to the mainland after their mother was (presumably) murdered. Steve went to the Army and Navy Academy in Carlsbad, California while she lived with their Aunt Deb several hours away. As a result, both siblings had harbored resentment over their father splitting up the family and drifted apart over the years; in the episode "Lanakila", she comments to her brother that the last time they met in person was at their mom's funeral over fifteen years ago. She is the "black sheep" of the family, wandering from job to job, and was said to be living in Los Angeles when Steve returns to Hawaii for good. In a scene deleted from the Pilot episode, Steve mentions bailing her out of trouble more than once and keeping it from their father to "let Dad go to his grave believing that you were his perfect little girl". She takes a job as a flight attendant but quit after her so-called friend Angela had betrayed her and took advantage of her naivete to be a mule for trafficking blood diamonds. In season 3 Mary returned to Hawaii working as a caretaker, originally not wanting to reconnect with Doris she later meets her after strong encouragement from Steve and the person she was caring after.

In season 4, Mary adopts a baby girl and names her Joan, after her father. Steve was initially against it but he comes to accept Joan after being forced to babysit her for the day. Since then, Mary and Steve have reconnected and she regularly sends him videos of Joan.

In the original show, Mary Ann only appeared in a two-episode arc. She was also estranged from her brother and was married and had an infant son who died of cancer. She was portrayed by Nancy Malone. In the reboot, the character features more in Steve's life and reconnected with him.

TitleDoctor
OccupationChief Medical Examiner
FamilyMr. & Mrs. Bergman (adoptive parents)
SpouseSabrina Lane
ChildrenTunde (adoptive son)
RelativesMachiyo Takeshita (biological mother; deceased)
ReligionJudaism

Dr. Max Bergman is a former medical examiner who belonged to the City and County of Honolulu. Bergman was initially billed as a recurring character but Oka joined as a series regular and has been part of the main cast since Season 2.[1]

Dr. Bergman was first introduced to Five-0 by Governor Jameson. He was playing the piano and then wordlessly proceeded to explain the victim's cause of death to Danny and McGarrett, before finally greeting them and introducing himself. He has the tendency to rattle off trivia, prompting the Five-0 team to cut him off and tell him to get to the point. Danny often mocks him with medical jokes. Despite his lack of social skills, he does get along with the other members of Five-0. He has a Halloween tradition of dressing up as a character from a Keanu Reeves film.

In the season 2 episode "Haʻalele", it is revealed that his biological mother, Machiyo Takeshita, was murdered by the notorious "Trashman", a serial killer in Hawaii from the 1980s who earned the nickname because his victims were all found in trash bags or the dumpster. He was born to a Japanese-American mother but adopted by a Jewish[2] family, the Bergmans, after a short stint in foster care, hence his last name. As an undergraduate at Arizona State University, he was a self-confessed party boy and earned the nickname "Beerman".[3]

Dr. Bergman is dating Sabrina Lane, a bank teller at Hawaii National Bank. He first saw her in the episode "Haʻawe Make Loa / Death Wish" while at the bank and had a crush on her at first sight. A botched bank robbery took place minutes later resulting in Sabrina being shot and Dr. Bergman having to put his medical expertise to use while being held hostage. Following the incident, he eventually works up the nerve to ask her out. It is implied that they are in a relationship (as of Season 6 Episode 14) as she is mentioned by Dr. Bergman numerous times in conversations with other members of Five-0; Rumer Willis, who portrays Sabrina, has only appeared twice on the show. It is revealed in the season 7 episode "Ka hale ho'okauwel / House of Horrors" that he married Sabrina during his sabbatical.[4]

Max retired from the Honolulu Medical Examiner's Office and from Five-0 in the season 7 episode "Ua ho'i ka 'opua i Awalua" and returned to Africa as a member of Doctors Without Borders.

TitleSpecial Agent
OccupationSpecial Agent, DHS
Special Agent/Profiler, FBI (formerly)

Special Agent Lori Weston is a former DHS agent with a background as a profiler. Due to the circumstances of her assignment McGarrett initially views her with suspicion and assigns her to "babysit" the victim's parents in a kidnapping case on her first day on the job.[5] A graduate of Pennsylvania State University,[5] her background as a federal agent proves to be an asset, as she is able to take down suspects and quickly proves her worth. She returns to the DHS at Governor Denning's request when Five-0 get tangled in an incident with an employee of the Russian consulate.

As Catherine Rollins was deployed, she spends a lot of time with McGarrett, but the latter regards her a good friend rather than a romantic interest. She had developed a crush on him, but realizes that McGarrett has always been in love with Catherine. Before her departure, she hands him the UH season tickets she had bought.

The character is based on Lori Wilson, interpreted by Sharon Farrell in the original series of 1968. She becomes the principal of the series in the twelfth season.

TitleLieutenant
OccupationMember of the Five-0 Task Force (inactive)
Private investigator (formerly)
United States Navy officer (formerly)
FamilyUnnamed parents
Significant otherSteve McGarrett

Lieutenant Catherine "Cath" Rollins, USN (Ret.) is the on-off lover of Steve McGarrett. How or when they met is never fully explained, but it has been implied that they have known each for a long time. Their first date was revealed to have been in 2002. It is likely they would have had to keep their relationship a secret due to strict fraternization rules in the U.S. military and the fact that McGarrett outranked her.

Cath is a "Navy brat" and moved around frequently due to her father's various assignments.[6] During Pro Bowl weekend, when asked why she supported the Dallas Cowboys, she explained that had never stayed in any one place long enough to feel an affinity for an NFL team.[7] She herself joined the Navy and is an Intelligence Officer. Like McGarrett, her military service record remains vague. She previously dated Billy Harrington, one of McGarrett's SEAL buddies whom she had worked with.

Cath is first introduced in the Season 1 episode "Lanakila", when McGarrett calls her for "a favor".[8] Later in the season, she stays with him while on leave, resulting in Danny commenting on how McGarrett had "that stupid smile" despite being called in on a Saturday to work a murder-abduction case.[6]

In the season 4 episode "Makani ʻolu a holo malie/Fair Winds and Following Seas", Cath persuades McGarrett to go with her to Afghanistan to find a young boy named Najib. Najib's father had saved her when she was injured and separated from her unit while deployed to Kabul. McGarrett was captured by Taliban insurgents and is nearly beheaded but a team of Navy SEALs rescue him in the nick of time. As a result, he escapes a court-martial and returns stateside with a stern warning that "these rogue ops of yours are over". Cath decides to remain in Afghanistan to continue her search for Najib and bids a tearful goodbye to McGarrett over the satellite phone. It was implied that McGarrett never really moved on, as he never indicated any interest in any of the women Danny or Ellie Clayton attempted to set him up with.

Cath makes a surprise return in the season 5 finale for Kono and Adam's wedding. Steve welcomes her with a hug when she surprises him at his backyard. She remained for the first three episodes of the series sixth season however she leaves once again before Steve is able to propose, saying that she had something to do. A heartbroken Steve tells her that he could not wait for her any longer if she decides to leave again, and she departs in tears. However, she makes a call to an unidentified person stating that Steve believed her story and that she was "ready". She once again returned in the series seventh season for the shows 150th episode to inform Steve that his mother had been detained following an attempt to break Wo Fat's father out of prison. She assists Steve and the rest of the Five-0 Task Force in rescuing Doris McGarrett and Wo Fat's father. She returns again in the eighth season's twentieth episode, getting Steve's help once again to find someone making dirty bombs out of an unused military bunker's depleted uranium.

In the series finale, Catherine cracks the show's final mystery- a cypher Steve's dead mother Doris had left for him. This aids in the capture of the show's final villain- the wife of McGarrett's long-time nemesis Wo Fat. In the final moments of the series, Steve and Catherine are reunited as they get ready to depart Hawaii.

Head of SWAT/police officer, CPD (formerly)
FamilyPercy Lee Grover Sr. (father)
Ella Grover (mother)
Percy Lee Grover Jr. (brother)
SpouseRenée Grover
ChildrenWill Grover[9] (son)
Samantha Grover (daughter)

Captain Louis Purnell "Lou" Grover[10] is the former head of the Honolulu Police Department SWAT Team. He was often at loggerheads with McGarrett over what he felt was Five-0's tendency to be trigger-happy with armed suspects and refusal to obey a "wait for SWAT" order, to the point where he lodges an official complaint with Governor Denning. The Governor dismissed Grover's complaint and then promptly orders the duo on an assignment to serve a warrant for a computer hacker. By the latter half of Season 4, he is fully accepted into the Five-0 ohana. In the season 4 finale, Grover's actions to rescue his daughter result in forced early retirement from HPD, but also allows McGarrett to recruit him to be part of the Five-0 team, which he accepts. The character was named after a Captain Grover (Scott Brady) from the original series.[11]

A 25-year veteran of the force, Grover graduated from the Chicago Police Academy in 1989, and was promptly recruited by the FBI to go undercover in the Philadelphia Black Mafia. Upon the completion of the assignment, he returned to the Chicago Police Department.[12] He left Chicago around 2012 or 2013, after an incident where he blames himself for having failed to save a boy who was taken hostage by his father, which ultimately resulted in a murder-suicide.[13]

He and his wife Renée (portrayed by Michelle Hurd) have two adolescent children: daughter Samantha (portrayed by Paige Hurd) and son Will (portrayed by Chosen Jacobs). The Grovers are a close-knit family and Lou is shown to be a doting father who is fair but firm with his children. As Danny also has a daughter, Grover sometimes gives him tips and unsolicited advice on dealing with preteens.[14] Although he loves his wife and vice versa, he has a tendency to forget important dates such as birthdays, anniversaries and Valentine's Day. In season 6, he forgets about Valentine's Day and hastily makes plans but Renée saw through it and he ends up in the doghouse as a result.[10] The Grovers live in the Honolulu neighborhood of Manoa.[12]

Despite Grover's rocky introduction to the Five-0 team, he has since become a valued member of the team. He has an ongoing good-natured rivalry with McGarrett. McGarrett would light-heartedly joke about Grover being a "city boy" out of his element on a tropical island[15] while Grover would poke fun about McGarrett getting himself into trouble because of his refusal to ask for help. Unlike McGarrett, Danny Williams took longer to accept Grover but they bond over the fact that they are the only members of the team with children and would often vent their frustrations to one another about parenting issues. Their friendship becomes slightly awkward after both discover that Will and Grace had been dating behind their backs.[16]

Grover's weapon of choice is the Kimber Warrior.

TitleSpecial Consultant
OccupationFive-0 Task Force
FamilyUnnamed father (deceased)
Unnamed mother
Isabel Ortega (younger sister)

Jerry Ortega is a conspiracy theorist who lives in his mother's basement (until she moves to Maui) who regularly assists the Five-0 Task Force with various cases. He was first introduced in the episode "Ka 'oia'i'o ma loko / The Truth Within". Jerry was classmates with Chin Ho Kelly at Kukui High and they were in the school band. A running gag in the show is the fact that he is either resistant or reluctant to use cellular technology to communicate with McGarrett (e.g. he once used a rotary phone to directly call McGarrett about updates for a case) and tends to ramble about conspiracies over everything. The Five-0 team largely tolerate and humor him as more often than not, his conspiracy theorist ramblings provide the team with a lead or valuable insight into a case. After much pestering, in season 6, McGarrett finally lets Jerry have his own "office"—an empty file storage room in the basement—and officially hires him as a "consultant".

Jerry is a fan of Elvis Presley, which was discovered when Five-0 was called to investigate a murder of an Elvis impersonator in the episode "Ua heleleʻi ka hoku / Fallen Star". In the same episode he shows off his musical talent by singing at the open mic when hanging out with the team for drinks after the case. While his job officially is a consultant, he operates behind the scenes as a technical operator, often providing information about the cases Five-0 investigates or technical support when they are in the field. In the episode 'Ua Malo'o Ka Wai', Jerry is awarded his very own Five-0 badge after he coordinates with Duke Lukela and HPD to rescue Five-0 from the Yakuza.

In the season 10 premiere, it is revealed that Jerry had been shot, continuing the cliffhanger left in the Season 9 finale. Two weeks later while recovering in a hospital, Jerry begins thinking about moving on to other things after his near death experience. After helping Five-0 with a new case, Jerry ultimately decides to move on from Five-0 and write a book that he no longer wished to put off until it was “too late”.

Despite the fact that he no longer appears on the series, the producers have confirmed that he will be appearing in an episode of MacGyver.[17]

Tani Rey was first introduced in the season 8 premiere as a lifeguard who was kicked out of the police academy for cheating. Steve asks her to go undercover to assist Five-0 on a case. She originally turned him down however she later changed her mind and eventually became an officer on the Five-0 Task Force. It was revealed that she has a delinquent brother named Koa and Tani repeatedly bails him out of trouble, including saving him from an HPD raid moments before he would've been arrested. Despite her best efforts to help him, Koa ends up overdosing and would have died if Adam and Noelani had not intervened. He is sent to rehab to get cleaned up, but decided to stay to work as a counsellor. She and Junior Reigns became a couple in Season 10 episode 17.

Thomas Hoapili (Cousin)
Maggie Hoapili (Niece)

Kamekona Tupuola is the owner of Waiola Shave Ice, Kamekona's Shrimp Truck and Kamekona's Helicopter Tours. Kamekona comes from a typically large Polynesian family and often mentions various relatives whenever one of the members of Five-0 needs a favor, whether for a personal matter or for an investigation. His late cousin, Thomas Hoapili, was a master of Kapu Kuʻialua, an ancient Hawaiian martial art, as is Thomas's daughter, Maggie (portrayed by Summer Glau). Another cousin, Flippa (Shawn Mokuahi Garnett), often helps Kamekona at the shrimp truck.[18]

Kamekona was introduced in the Pilot as Chin's confidential informant and owner of a shave ice stall on the beach. His full background and how he first met Chin were only revealed in the season 6 episode "Kuleana / One's Personal Sense of Responsibility".[19] As the elder son in an impoverished family, he would skip school to earn extra money to help his single mother. He gradually became a drug kingpin and did some time at Halawa. As a result of his younger brother's involvement with a noted drug dealer, whom Chin Ho Kelly was coincidentally investigating, he agreed to be a CI for the HPD on the condition his brother is let go without any charges. Chin visits Kamekona in prison and gives him Napoleon Hill's book Think and Grow Rich, beginning a friendship that continues to the formation of Five-0. He started his shave ice stand while getting back on his feet after being released. In the season 5 finale, he mentioned that his shrimp truck business is now in doubt, after Steve and Danny dropped a nuke into the sea to prevent it from blowing up on land. In season 3 he qualifies as a helicopter pilot with the help of McGarrett.[20] Members of the Five-0 Task Force and their families are often seen patronizing his shrimp truck or asking him for favors (e.g. he babysat Grace Williams, Danny's daughter, and chaperoned Steve's sister Mary while they were at work).

Sergeant Duke Lukela is a veteran HPD officer who often acts as a liaison to Five-0. He was one of the few HPD cops who was not antagonistic towards Danny or the other Five-0 members from the beginning, as he was colleagues with Steve's father and many of Chin and Kono's family members (they come from a family of cops) and had known the three of them since they were children. In "Hookman", he was shot by Curt Stoner (Peter Weller), but survived and recovered. He is married to Nalani (portrayed by Chun's real-life partner Laura Mellow.[21])[10] They have a granddaughter.

Chun is the son of Kam Fong Chun, who played Chin Ho Kelly on the original Hawaii Five-O.[11] The character Duke Lukela was portrayed by Herman Wedemeyer in the original series. Chun himself also played various minor characters throughout the original series.

Significant otherLayla (ex-girlfriend)
Tani Rey (girlfriend)

Junior Reigns was first introduced in the second episode of season 8. Junior came to Steve looking for a job on the Task Force immediately after being discharged from the U.S. Navy. Steve initially turned him down however after Junior insists Steve tells him that before becoming a part of Five-0 he must train at the police academy. Junior eventually receives his badge and joins Five-0.

Unlike the other members, Junior rarely questions Steve's tactics or methods due to their shared military background as Navy SEALs and has occasionally had to explain to Danny Williams and Lou Grover the rationale behind Steve's actions. Other characters have noted similarities between Steve (when he first started Five-0) and Junior, in particular Junior's instructor at the HPD Academy.[22]

In season 8, it is revealed that Junior had been putting up at a homeless shelter despite having family on the island (Steve later finds out and asks him to move in with him until he finds an apartment).[22] Throughout season 9, it is gradually revealed that he has avoided going home as he was estranged from his father and they only communicated through his mother. It has been implied that Junior had grown up in a loving and stable home, unlike some of his peers at school who mixed with the wrong crowd. Junior had initially planned to return to marry his high school sweetheart Layla after a tour but re-enlisted without consulting her, leading to them breaking up.[23] He left the Navy with the rank of Special Warfare Operator 2nd class.

Junior had a sister Maya, who was killed in a car accident when he was young, and their father never fully got over it, leading to him vehemently opposing his only remaining child enlisting in the Navy. However Junior went against him and followed his footsteps into the military[24] and it deepened their estrangement to the point where they were no longer on speaking terms for years.

Adam Noshimuri, Kono's husband who becomes a new head of the Japanese Yakuza after Wo Fat murders his father, Hiro. First introduced in the season 2 episode "Pahele / Trap", he has been trying to legitimize and clean up his organization with the intention of distancing himself from his father's criminal past. When he and Kono first started dating, the Five-0 team were extremely suspicious of him, particularly Steve and Chin – the former due to his father's history with the yakuza and the latter due to him seeing Kono as a younger sister. He is accepted into the Five-0 ohana after proving his love for Kono. After killing his brother Michael (Daniel Henney) to protect Kono, he and Kono leave Hawaii and go into hiding. He comes out of hiding after his brother's loyalists are no longer a threat. At the beginning of Season 5, Adam proposes to Kono and at the end of this season they marry. In "Mai ho`oni i ka wai lana mālie", Adam is shot by Gabriel Waincroft, who runs away with the money that Adam would use to distance himself from the Yakuza. Almost immediately after Adam killed two Yakuza thugs in "Piko Pau 'iole" to save himself and Kono, Gabriel buys off Adam's debt in order for his cartel to team up with the head of the Hawaiian Yakuza. He subsequently turns himself in to the Honolulu Police Department. After a short legal battle he is sentenced to 18 months in prison, which was agreed on since he had been acting in self-defense. He has been released on parole as of the season 7 episode "Ka 'Aelike / The Deal".

Adam is the elder son of Hiro Noshimuri and, with the introduction of his brother Michael, it becomes apparent that Adam was the brains who ran the legitimate business front of their father's operation out of New York while Michael was the brawn who usually took care of the "dirty" side. For example, when the Five-0 team uncover a yakuza burial site, it is revealed that he knew nothing about it.[27] He is implied to be a Nisei (first generation American-born Japanese American) and his grandfather served in the Imperial Japanese Navy.[2]

Dale was initially confirmed for a four-episode arc but following positive fan response, became a recurring guest star.[28] His character had been written as a potential antagonist for McGarrett and the team as he saw the latter as a stumbling block in his quest for answers about his father's death.[29] Like his character, Dale is of Japanese descent.

In the season 8 episode I Ka Wa Ma Mua, I Ka Wa Ma Hope (The Future is in the Past) Danny dreams of the future and Adam has a child with Kono. In the Season 8 episode Ka Hopu Nui 'Ana (The Round Up), after a devastating hit on Hawaii's crime bosses by a new crime syndicate, Steve asks Adam to head up a new special division within the Five-0 Task Force to focus specifically on organized crime. Through his investigation, he discovers he has a half-sister, Noriko, who tries to manipulate him by threatening Kono, Chin, Abby and Sarah. However, Adam ends up leaving the island after his informant, Jessie, is killed, but, at the same time, Noriko is killed. In the season 8 finale, Tani discovers a gun in Adam's house, leading her to believe Adam may have been responsible for Noriko's murder.

In the season 9 episode, "A'ohe Mea 'Imi A Ka Maka", Tani tests the gun's ballistics and confirm it was the murder weapon. In "Aia I Hi'Ikua; I Hi'Ialo", Adam returns home, depressed by his break-up with Kono. However, Danny helps him through his pain and as a thank you for everything he has done, he offers Adam a spot on Five-0 which he accepts. After HPD got an anonymous tip about Adam's gun but was unable to find it, he confronts Tani about it, but she reveals she did not call it in after Adam helped save her brother's life, leading them both to discover a third party is trying to frame him.

John McGarrett

Portrayed by William Sadler and Ryan Bittle

Sergeant John McGarrett, HPD (Ret.) (1942-2010) is the father of Steve and Mary Ann McGarrett and (presumed) widower of Doris McGarrett. His own father, Ensign Steve McGarrett, was killed in action on the U.S.S. Arizona (BB-39) during the attack on Pearl Harbor and John was born three months later on March 15. John would follow in his father's footsteps into the navy, serving in the Vietnam War and reaching the rank of Lieutenant before becoming a Honolulu Police Department detective. After Doris' presumed death, he launched his own investigation and sent Steve, then a high school junior, to board at the Army and Navy Academy in Carlsbad, California and Mary to live with his older sister Deb, who lived several hours away from Steve's new school, for their safety. It is presumed that this was the last time the siblings ever saw him in person as they became estranged from their father for sending them away; Steve only learns the real reason why his father split up the family when he returns to Hawaii to head the new task force following John's murder. In light of the revelation, Steve and Mary were able to let go of their animosity and are often seen visiting his grave site.

John has been mentioned a number of times as Steve regularly works with HPD officers, many of whom were John's former colleagues, and is implied to have been a much respected figure within the police force. Even renowned diamond smuggler and fence August March (Ed Asner) paid tribute to John's sense of integrity by telling Steve about how John turned down his $100,000 bribe over three decades ago.[30]

John McGarrett was murdered by Victor Hesse on September 20, 2010, as witnessed by Steve, who was overseas on a highly classified mission in South Korea, via satellite phone. He was buried at the National Cemetery of the Pacific with full military honors. In the 100th episode "Ina Paha" ("If Perhaps") he is never murdered by Hesse and is able to reconnect with Steve when he returns home.

Doris McGarrett

Portrayed by Christine Lahti

Doris McGarrett is the wife of the late John McGarrett and mother of Steve and Mary Ann McGarrett. She was presumably murdered by a car bomb when Steve was aged fifteen or sixteen. It is revealed in Season 3 that she was a former CIA operative who went by the alias "Shelburne" and had faked her own death as a cover to escape underground in order to protect her family.

In the Season 3 premiere, Joe White brings Steve to Suruga Bay in Japan where mother and son are reunited. Steve was hostile to his mother, even refusing to call her "Mom", due to the years of resentment over how the family was torn apart by her supposed death and watching his father grieve over her. Mary also initially refused to see her after learning the truth from Steve. For the rest of the season she constantly refuses to tell everything to Steve and he does not fully trust her. He sends Cath to "babysit" her at a safehouse but Wo Fat bypasses the security system and Cath into the house to confront Doris. Despite being a crack shot and armed, ballistic evidence showed that she had intentionally shot away from him, which she attributed to her nerves and shock over Wo Fat's sudden appearance, but Steve refuses to believe her story. In the third-season finale she leaves Hawaii with Kono and Adam to help them evade the Yakuza with her promising to Steve that her story is "To be continued.". Over the next two seasons, bits and pieces (and rumors) of Doris' connection to Wo Fat are revealed. Steve only learns the full truth after he was abducted and tortured by Wo Fat in the 100th episode. She is mentioned in the episode "Pono Kaulike / Justice for All" where she uses her contacts to keep her son safe from a rogue CIA agent who attempts to have Danny and Chin framed to cover his tracks. Steve was able to use the information she provided to Joe White to exonerate his co-workers. In the seventh seasons 150th episode Steve learns from Catherine that she was captured after attempting to break Wo Fat's father out of prison. Steve and Catherine along with the rest of the team (excluding Danny) go to Morocco to break her and Wo Fat's father out. Later Doris is seen again in Season 10 Episode 7 where she is reunited briefly with Steve for a little before she is stabbed and dies.

Aunt Deb

Portrayed by Carol Burnett

Debra "Deb" McGarrett is the late older sister of John McGarrett and aunt of Steve and Mary Ann McGarrett. She raised Mary when John had sent the kids away from Hawaii for their safety after Doris was presumed to be murdered by a car bomb. Steve and Mary both see her as a maternal figure and she, having never married or had children, treats them as her own. Deb had been a struggling singer on the cusp of a big break when she left a promising career to raise Mary. In season 4, she pays Steve a surprise visit for Thanksgiving and reveals that she had stage four cancer. In season 5, she agrees to go for chemotherapy and her brain tumor has shrunk. She marries Leonard Cassano (Frankie Valli), a retired defense lawyer with stage four leukemia whom met during chemo. In the episode "Ua Ola Loko I Ke Aloha / Love Gives Life Within" she returns to Hawaii with Leonard's ashes on the pretext of spending time with Steve, Mary and Joan but does not tell them that she was actually dying and trying to complete her bucket list. She passes away peacefully in Steve and Mary's childhood home (which Steve has lived in since his father's death) after fulfilling all but one thing on her bucket list—climb a tall mountain. Steve and Mary complete her list by scattering her ashes on the mountain top.

Grace is named after a former partner of her father's who was killed in the line of duty by a criminal.

Grace is well-liked by the rest of the Five-0 ohana. She took to "Uncle Steve", as she calls McGarrett, who affectionately calls her "Gracie". Whenever Danny was unavailable due to extenuating circumstances, McGarrett would be the one to pick her up from school or personally reassure her.

Grace was often the source of Danny's disputes with his ex-wife over his visitation rights. Rachel would use their daughter as leverage and make empty threats about rescinding or lessening his visitation days. Eventually, Danny takes the matter to court and is awarded joint custody, meaning that Grace cannot move away from Hawaii without Danny's approval.

When Steve McGarrett returned home to Hawaii to bury his father, who was murdered by arms dealer Victor Hesse, she requests him to set up a task force with "full immunity and means" to apprehend criminals such as Hesse. McGarrett flatly turns her down as he felt she only asked him to do so for political reasons and boost her ratings. Once he realizes he had no jurisdiction over the investigation, he quickly accepts the job and sets the "Governor's Task Force", which came to be called "Five-0".

Over the course of season 1 it is revealed that Governor Jameson was actually colluding with Wo Fat and other criminals such as Adam's father Hiro. In the season 1 finale it is revealed that she was responsible for the murder of Laura Hills. McGarrett confronts her about it in her office and records her confession on his phone.

He appears to be well known amongst SEALs from his time as a trainer at the Naval Special Warfare Center, as McGarrett's former SEAL teammate Billy Harrington and SO2 Graham Wilson, who was a person of interest in the episode "Hoʻapono", both knew of him. In the season 2 episode "Kiʻilua / Deceiver", he is forced into retirement after leading an unsanctioned mission into North Korea to rescue McGarrett.

White was one of the few people who knew about Shelburne but he refused to disclose it to McGarrett as he knew it would only hurt him even more emotionally. He would repeatedly give excuses or evade McGarrett's persistent questions about the true identity of Shelburne. As a result, McGarrett, despite seeing him as a father figure, regards him with some distrust.

Joe was killed in season 9, because of Greer's treason (Steve's ex lover).

Governor Samuel "Sam" Denning was Lieutenant Governor of Hawaii, replacing Gov. Jameson after her death. He is much more "by the book" and withdraws his predecessor's assurance to the Five-0 Task Force of "full immunity and means". Instead, he brings in former federal agent Lori Weston as a "spy" to keep McGarrett and the rest of Five-0 in line, much to their displeasure. In season 3 he and McGarrett come to a mutual agreement to be open with one another about investigations, with McGarrett pointing out that Governor Jameson's dishonesty was what got her killed. Although not always agreeing with McGarrett's style, Governor Denning does vouch for and backs him when necessary. For example, he dismisses Lou Grover's complaint against McGarrett in season 4 and instead forces the both of them to serve a warrant together and work out their differences themselves.

Nahele Huikala

Portrayed by Kekoa Kekumano

Kamekona agrees to let Nahele work for him as a waiter at the shrimp truck as part of the agreement that McGarrett will not file charges if Nahele keeps his end of the bargain to stay out of trouble. Since then he has looked up to McGarrett as a mentor and an older brother figure. In season 6, his father is released from prison and successfully files for custody of him. Distraught, Nahele confesses a long-buried secret to McGarrett explaining why he still refuses to see his father even though the latter turned his life around.

In several episodes she aided the Five-0 Task Force by securing arrest warrants or providing advice.

McGarrett meets her by chance when he sees her putting flowers on his father's grave and accosts her. She reveals that John was the uniformed officer who responded to the scene of her father's murder. Every Christmas since then he would visit her and give her a present. According to Chin, John made an effort to keep in contact with her, partly out of guilt and regret for sending his two children away. Ellie reveals that prior to his death, John had called her up to tell her that he had found new evidence. McGarrett recalls finding a "Aces High" matchbook in his father's Champ toolbox and decides to reopen the case in memory of his father. Five-solves the case with the help of a young drug runner whom Paul had tried to help back then (unsuccessfully) and wanted to repay Paul for his kindness.

During his days as a SEAL, McGarrett was part of a task force which had been investigating and tracking the Hesse brothers for several years. He and his buddy Freddie Hart were sent into North Korea on a classified operation to kidnap Anton Hesse but Hart was killed and Anton was eventually killed when the convoy he and McGarrett were being transported in was attacked. In the pilot, McGarrett personally shoots Victor Hesse but his body was never found. Victor later resurfaces and is eventually caught and sent to prison where he is killed by Wo Fat who was posing as a corrections officer.

Gabriel Waincroft

Gabriel Waincroft (Christopher Sean) is the younger brother of Malia Waincroft, the late wife of Chin Ho Kelly. As an adolescent he repeatedly got into trouble with the law and Malia went to Chin, then her boyfriend, for help in setting him straight. Gabriel was initiated into a gang after killing Chin's father and rose through the ranks of the (fictional) Culiacan cartel based in Sinaloa, Mexico.[34] With Wo Fat's death, Waincroft is now the team's primary antagonist. He has been described as daring and ambitious, particularly after he had his men attempt to assassinate the heads of three different criminal syndicates during a high-profile boxing match (the attempt was discreetly foiled by Five-0), in the episode "Ka Makau kaa kaua / The Sweet Science". In "Pa'a Ka 'ipuka I Ka 'Upena Nananana", he was badly wounded and died in surgery from cardiac arrest. His daughter Sarah is currently being cared for by Chin as her legal guardian.

She is married with two daughters. It is mentioned in season 8 that she had been murdered in prison.

Sang Min Soo

Sang Min Soo (Will Yun Lee) is an informant and former snakehead who was associated with Wo Fat and imprisoned on the mainland for his safety after he testified against his former associates. He chooses to be transferred to Halawa to be nearer to his young son. His appearances are often met with annoyance by the Five-0 team as he would mock McGarrett and Chin, try to rile Danny up or crack inappropriate jokes at Kono (he calls her "Spicy Hot"). The team generally tolerate him as he does provide valuable and much-needed intel for the team on several occasions.

Toast Charles

Adam "Toast" Charles (Martin Starr) is one of Danny Williams' CIs. He is a highly skilled hacker who sometimes helps the Five-0 team with cases related to the cyber-crime underworld that require a more underhanded approach. He was killed in the Season 8 episode "E uhi wale no 'a'ole e nalo, he imu puhi" / "No Matter How Much One Covers a Steaming Imu, The Smoke Will Rise" after his identity as a CI was leaked.

August March

August March (Ed Asner) is a renowned diamond smuggler who was jailed for over three decades and had been released from prison for six months, according to Captain Fryer in the season 2 episode "Kalele / Faith". He committed a suicide in Season 3. Ed Asner portrayed the character in the original series and was one of several actors who returned to the 2010 reboot.[11]

JC Dekker

Jason "JC" Dekker (Xzibit, credited by his real name Alvin Joiner) is a former gang leader and small-time arms dealer who was re-arrested for violating his parole. The Five-0 Task Force crossed paths with him while investigating the murder of an undercover ATF agent in the episode "Ua Nalohia / In Deep".

Detective Kaleo

Detective Kaleo (Jason Scott Lee) is a corrupt former Honolulu Police Department cop who was imprisoned for his involvement in the murder of fellow cop Detective Meka Hanamoa, who was the partner of Detective Danny Williams when the latter first joined the HPD. He was initially housed in protective custody due to his former occupation but was sent to "general population" after he aided his brother Daryl in the trafficking of conflict diamonds, indirectly causing McGarrett's sister to be coerced into becoming a mule.[30] His brother is killed in Season 2 and Kaleo is finally killed in Season 3 by Chin Ho Kelly when he tries to kill him.

Frank Delano

Frank Delano (William Baldwin) is a corrupt former HPD homicide detective who founded his own criminal syndicate composed exclusively of former cops. After Kono was "fired", Delano recruited her into the syndicate. Unbeknownst to him, it was part of Captain Fryer's plot to arrest Delano and his associates. Delano was killed by Chin after Five-0 cornered him and his crew in the season 3 premiere. His brother Paul (portrayed by William Baldwin's real-life brother Daniel) later seeks revenge by drugging and kidnapping Chin.

Gerard Hirsch

Gerard Hirsch (Willie Garson) is a known conman who did time in Halawa after being arrested in the episode "Uaʻaihue" for stealing a Van Gogh painting and for forgery. The team encounter him again in season 6 during an investigation into a case involving a dead counterfeiter and his stash of counterfeit hundred-dollar bills found on several murder victims. Hirsch currently runs his own crime scene clean-up company as part of his plan to "reform" and live an honest life. His expertise as a highly skilled former forger and extensive knowledge of art history have come into handy at times.

Jason Duclair

Jason Duclair (Randy Couture) is a serial arsonist and murderer who was notorious for picking married couples and setting their houses on fire, after ensuring that their doors, windows and any exits were locked.
