11"Crush, Chop, and Burn"Victor GonzalezChris Peterson & Bryan MooreFebruary 27, 2012 (2012-02-27)101–1021.27[4]

In the fictional town of Mission Creek, Leo and his mother, Tasha, move in with billionaire inventor Donald Davenport, Leo's step-father. In a secret underground lab in Davenport's high-tech home, Leo discovers three bionic superhuman teenagers named Chase, Adam, and Bree, known as the Lab Rats. Leo learns they have lived their whole lives in the lab, where they have been training their bionic abilities for future classified missions. Leo secretly takes them to his school, Mission Creek High, where their lack of experience with the outside world causes chaos, in part because their bionics can be inadvertently activated through their emotions. When Davenport finds out, he bans Chase, Adam, and Bree from having contact with the outside world. However, Leo, in appreciation for making him more popular at school, throws a party for Chase, Adam, and Bree in Davenport's house, only to get caught when Davenport and Tasha return home during the festivities.

After disobeying his orders, Davenport decides it is best to send Chase, Adam, and Bree to his top secret facility in the Arctic to finish their bionic training. Davenport creates robot versions of them to hang out with Leo, but the real Lab Rats switch places with their replacements. However, Tasha decides that she does not want Leo to hang out with robots and tells Davenport to recycle them, not knowing they were the real children. Once at the recycling plant, Chase, Adam, and Bree use their bionics to avoid various hazards, but must backtrack when Leo arrives to rescue them. Davenport and Tasha learn of the mix-up and arrive at the plant. After seeing the children risk their lives for each other, Davenport decides to let them stay at home to complete their training. He also agrees to let them attend school, as long as they maintain their bionic secret and control their emotions to prevent further glitches.

After failing to stop Davenport, Chase informs Dr. Ryan of the flaw and the two of them work together to safely get Davenport back on the ground. Working together, they reverse the polarity of the magnets that propel the elevator and it begins coming down ten times as fast. Leo uses his bionic strength to stop the elevator from hitting the ground, but he then realizes that Davenport already used a parachute to escape. When Leo tries to escape from holding the elevator, it drops and crushes his leg. Because of the extensive injury, Davenport gives Leo a bionic leg.

7912"Bionic Action Hero"Victor GonzalezHayes Jackson and Ken BlanksteinAugust 5, 2015 (2015-08-05)410–4110.97[80]

Douglas tells Adam, Bree and Chase that his ex-girlfriend from college, now a film director named Giselle, will be making a film titled Bionic Action Hero" based on them and starring an up-and-coming actor named Troy West. Troy and Giselle visit the island to learn about the bionic team, and Bree immediately falls for Troy. Giselle is intrigued when Douglas mentions Marcus, saying he was his greatest invention who had the combined abilities of Chase, Adam, and Bree. In the mentors' quarters, Troy explains to Bree that for the film, he needs to figure out how Chase's abilities work or Giselle will fire him. Bree downloads the information about Chase's bionic chip and gives it to Troy. He secretly gives the information to Giselle, who conspires to eliminate the team and start her own race of genetically modified androids. At the movie studio, Bree learns about Giselle and Troy's plan. During filming, Bree stops Troy before he can fire a blaster gun at Chase, Adam, Leo, and Douglas. Bree explains to everyone that Giselle only lured them to the set to kill them. Giselle then explains to them that she planned to unveil her androids until Chase, Adam, and Bree became publicly known as bionic humans, which would steal attention from her androids. Giselle also reveals that all of her film crew members are androids, including Troy. With Chase's schematics, she plans to give all of them super intelligence. However, Bree and her team have Giselle's laptop with the schematics, and Chase and Douglas unleash a virus on Giselle's computer servers to destroy her back-up copies. During a battle between the androids and the others, Troy knocks Chase unconscious and carries him away, with Giselle planning to rip out his bionic chip to learn how to implement his intelligence in the androids. The film set has been rigged to explode, but Adam, Bree, Leo, and Douglas escape. In Giselle's lab, she tells Chase that Troy is an old android model and that she has created a newer version capable of taking any appearance. Upon learning of Chase's location, Adam and Bree go to rescue him. Meanwhile, an android attacks the academy, and Leo and Douglas stay behind to stop it. At the lab, Adam and Bree fight Troy while an android tries to rip out Chase's chip. After knocking out Troy and Giselle, Adam and Bree race to Chase's side, but are too late. Giselle shows up and mockingly apologizes, but Chase appears and reveals that he is alive, while the deceased version is an android replica that he put in place to fool Giselle. She unleashes more androids, but Leo and Douglas arrive and quickly destroy them. Troy awakens and double-crosses Giselle because she was planning to replace him with a newer android model. With her out of the way, he plans on not only destroying bionic humans, but also all humans. He knocks out Giselle and takes Bree hostage, but she manages to dunk him into a sink of water, which short-circuits him. Giselle manages to escape and later retrieves the remains of Marcus from the rubble of Douglas' old lair.

8013"One of Us"Guy DistadJulia MirandaAugust 12, 2015 (2015-08-12)4160.58[81]

While Leo is in Mission Creek to see Janelle, S-1 arrives unexpectedly at the academy. Like the other students, her memory is blank, but she has been having headaches as well as flashbacks of Krane. Chase and Douglas agree to help her, and they learn that she has a doomsday virus in her because she was under the influence of Krane's Triton App. Chase realizes that he, Adam, Bree, and the students also have Krane's doomsday virus implanted in them. Chase and Douglas try to find a way to save everyone before they die; they believe that the solution to the virus is somewhere in S-1's memories. Leo returns to the island and attacks S-1 upon seeing her, thinking she is still a threat. He knocks her unconscious, inadvertently putting the others' lives in jeopardy. Meanwhile, before they die, Adam and Bree plan to do things they never got to do before. Adam wants to break the world record for blowing the most balloons with his pressurized lung capacity ability, while Bree wants to have a party with all of her friends from Mission Creek. Bree realizes she made a typo in her party invitation, which makes her friends think she is having a party without them because she does not like them. To cheer Bree up, Adam invites random strangers from the pier to attend her party. Bree still wants her friends to come, but she is glad to know she has a brother who cares. When S-1 awakens, Chase and Douglas try to have her remember anything that could end the virus, but their plan is unsuccessful. Chase devises a new plan to have the infected people briefly die through his own doomsday virus, allowing Krane's virus to be stopped. Douglas then uninstalls Chase's virus in time to revive them. Afterwards, Leo and Taylor become friends.

8114"Bob Zombie"Guy DistadHayes JacksonSeptember 30, 2015 (2015-09-30)4170.46[82]

Douglas creates a device that makes any bionic human as smart as Chase. Douglas tests it on Bob, who then starts spending time with Chase, which upsets Adam as he and Bob no longer share the same interests. Douglas gives the super intelligence to the rest of the students, but when Adam tries restoring Bob to his former self, he accidentally gives all the students the intelligence of farm animals, reducing them to mindless zombies who aimlessly wander around. Douglas eventually restores the students to their original selves and is convinced that it is best not to increase their intelligence, as doing so also alters their personalities and interests. Meanwhile, Perry learns that the island was never registered as a country, so she registers it as her own island nation known as Perryland, with her as dictator. To regain the island, the group arranges a wedding between Perry and her crush Douglas. Leo has Perry sign a marriage license, but it actually turns out to be a paper relinquishing ownership back to the Davenports.

Perry is overworked as head of security for the island, so Davenport gives her a partner by installing Eddy into a synthetic human body to help her. Davenport has replaced Eddy's disrespectful personality to make him nicer. However, Perry does not like the new Eddy and restores his old personality, after which he attempts to harm the students. Leo and Bree inform Davenport about Eddy's personality change, but he initially thinks that they are lying. Davenport later learns the truth, and Perry and Eddy battle each other, with her eventually using a weapon to blow his new body apart. Eddy is then restored to his former location on a wall monitor. Meanwhile, Chase is eligible to receive a job on an environmental task force committee, but first must have an interview with the U.S. president, who comes to the island with the committee members to conduct the interview. The president and his team become bored by Chase's intellect and decide to give Adam a chance to get the job instead. However, they soon realize that Chase is the best person for the job.

While Davenport takes the students to the Davenport Birthplace Museum, Bob stays behind and Adam teaches him about Halloween. Meanwhile, despite Douglas' objection, Perry visits a nearby island full of dangerous wildlife to search for things with her metal detector. Leo, Bree, and Chase go with her. Perry discovers a metal skull and secretly brings it back to the academy, despite Bree and Chase's earlier demands that she put it back where she found it. Perry tries to sell the skull online, but when the others see it, Chase decides to take it back to the other island. Bree, Leo and Perry experience several near-fatal accidents and become convinced that the skull has cursed them. They subsequently learn that the accidents were caused by Chase, who has become evil from the skull. Bree takes the skull back to the other island. Douglas returns to the academy and learns of the situation, explaining that Chase has actually become infected with a virus that affects anyone who touches the skull. He says that he previously used the skull as a paperweight until he spilled a virus on it and eventually decided to bury it on the other island. Perry was not infected because she was wearing gloves. Bree returns to the island with the infection and tries to harm the others along with Chase. Leo realizes they can inject Davenport's nanobots to remove the virus from Chase and Bree. Adam pretends to be infected with the virus so he can get close enough to inject Chase and Bree, thereby curing them.

8417"Lab Rats: On the Edge"Victor GonzalezHayes Jackson & Greg SchafferNovember 11, 2015 (2015-11-11)421–4220.61[85]

Davenport tells the group that the president has decided to host an award ceremony because they have completed their one-thousandth mission. Although Leo has not gone on all of the missions, he wants recognition, but is upset to learn that the ceremony is only for Adam, Bree and Chase. Disappointed, Leo forms his own team with S-1, who calls herself Taylor now, and a student named Logan. Leo demonstrates to Chase, Adam, and Bree that he and Taylor can fuse their laser sphere abilities together to form an electromagnetic pulse attack capable of taking out any power source. Chase demands they stop the demonstration when Taylor becomes overwhelmed by their power, but Leo pushes on, hoping to impress the others. The resulting blast becomes too much for Taylor and it incapacitates her. Although she recovers, the blast has left her permanently blind. Feeling guilty for what he has done, Leo quits the academy and moves back to Mission Creek to live with Tasha. Meanwhile, Davenport has the chance to build an indestructible limo for the president. Douglas and Adam help to perfect the limo design for maximum safety against any threat. Douglas has also invented a gadget that allows Taylor to echo-locate to detect obstacles in her way, and she has continued her training. Later, the Davenports are in the limo on the mainland, heading for the awards ceremony. They go over a large bridge that begins to collapse after a transport ship crashes into it. As the limo dangles over the edge of the bridge, it locks down due to its design, thereby trapping everyone inside. Taylor and Logan learn of the bridge disaster and send the other students out to rescue people on the bridge, marking their first mission. Taylor and Logan also ask Leo to help out; he agrees and is surprised to learn that Taylor is not upset with him following the accident that blinded her. On the bridge, Leo and Taylor, with help from Logan, use their electromagnetic pulse attack to disable the limo's lockdown feature, allowing the others to escape through the sunroof. Everyone escapes except for Chase, who has difficulty getting out. Leo tells the others to evacuate while he rescues Chase. Later, Davenport decides to make Leo a mentor because he has proven to be a leader.

Douglas reveals that there is a fourth bionic child named Daniel, who is the sibling to Adam, Bree, and Chase. Douglas says Daniel has been living a normal life with an adopted family, but that he has just discovered Douglas as his father and now wants to meet. Daniel is unaware that he is bionic, as his abilities have never been activated due to him not having a capsule. Douglas agrees to let Daniel visit the academy, but he lies to Daniel by claiming that Chase, Adam, Bree, and Leo are his cousins and Davenport is his uncle, in order to keep Daniel's bionics a secret from himself. Daniel initially bonds with Douglas, but his bionics are inadvertently activated later on after he poses for a picture in one of the capsules. When Davenport and Douglas learn that Daniel's bionics have been activated, they tell Daniel the truth. Douglas tells Daniel that he has the ability to replicate any bionic ability by touching another bionic person. Daniel also finds out that his cousins are actually his biologic siblings. Filled with anger at Douglas' lying, Daniel goes out for air on the beach, where he and Leo have a conversation about Douglas. Later, Daniel, using Leo's abilities, accidentally causes a leak in the hydro-loop's fuel tank, which threatens to blow up the island. Adam uses his increased lung capacity to freeze the tank, but is unsuccessful, so Daniel replicates his ability and they team up. After freezing the tank, Douglas apologizes to Daniel for lying and Daniel decides to give Douglas a second chance.

8720"Space Colony"Victor GonzalezChris Peterson & Bryan MooreJanuary 20, 2016 (2016-01-20)424–4250.64[88]

Davenport brings Tasha and the rest of the family to Davenportia, his new domed space colony located on a planet he discovered. Upon arriving, they learn that Perry has been living at Davenportia after she snuck in as one of the colonists. When Davenportia loses contact with Earth, Chase, Adam and Bree head out in a ship to fix the communication satellite. In space, Chase realizes the satellite is fine and that someone disrupted communications from within Davenportia. As Chase heads back to the ship, his jet pack malfunctions and drifts him off into space. Perry, who snuck aboard the ship, takes control and lands the crew on a deserted planet, where they rescue Chase. Meanwhile, at Davenportia, a punctured hole in the dome begins sucking out the colony's oxygen; Leo and Davenport work together to seal the hole, and Perry and the others return afterwards. Krane emerges and reveals himself as the cause of Davenportia's problems. After the attack that was thought to have killed him, Krane has been forced to wear a special mask that helps him breathe. With the aid of his new partner Dr. Gao, Krane intends to implant liquid bionics into the colonists and turn them into his bionic army. Davenport, Tasha, and the colonists are placed under mind control through the Triton App. Chase, Adam, Bree and Leo battle Dr. Gao, who is also bionic. Leo destroys Gao's liquid bionics and Bree removes Krane's mask, while Gao manages to escape. Leo shoots a hole in the dome to destroy Davenportia and foil the bionic army plans. Leo and the others lead Davenport, Tasha and the colonists to safety aboard the ship, and Davenportia collapses following their departure. It is discovered that Gao snuck on board and placed Leo under his control through the Triton App. Gao explains that he has launched a doomsday missile to wipe out human existence on Earth, as part of a plan to replace the population with a bionic civilization by injecting the colonists with the remainder of the liquid bionics. Adam, Bree and Chase battle Gao and Leo, eventually prevailing over them, although the missile remains on track to strike Earth. Krane has escaped the dome in a space pod and begins attacking the ship, until his pod is destroyed by one of the ship's missiles. Adam then puts on a high velocity escape suit and launches himself into Gao's missile, destroying it.

8821"The Vanishing Part 1"Victor GonzalezChris Peterson & Bryan MooreFebruary 3, 2016 (2016-02-03)4230.68[89]

Davenport and Douglas reveal that they have built an operating system upgrade for all the students' bionics. However, the upgrade does not work on Chase, Adam, and Bree because their bionic infrastructure is older, therefore leaving them at their current level while all the students are now much more powerful. Meanwhile, Daniel is brought to the academy because he had been using his bionics in public. Douglas decides to enroll Daniel at the academy with Leo as his mentor. Leo steadily tries to teach Daniel, but Daniel proves to be unteachable. Douglas rejects Leo's suggestion to give Daniel the upgrade, as Douglas wants Daniel to become responsible for his bionics, but Leo goes against Douglas. The students start to vanish from the academy, including Daniel. The students learn that Giselle has hacked into their chips and geo-leaped them into her chamber that blocks their bionic abilities. She plans to kill all bionic people and replace them with her androids, but she is upset to see that Adam, Bree and Chase are still at the academy. Later, Daniel sends a video message to the island, requesting help. Chase, Adam, Bree, Leo, Davenport, and Douglas go to rescue the students. Daniel leads them into Giselle's lab, but the doors immediately lock. Giselle comes out and shows them that the students are trapped in the chamber, including Daniel, while the Daniel who brought them into the lab reveals himself to be Marcus.

Giselle reveals she dug up Marcus from Douglas' old lair and rebuilt him, piece by piece. Marcus wants revenge on Douglas for leaving him to die. Marcus knocks everyone unconscious. Davenport and Douglas are tied together in chairs, while Chase, Adam, Bree, and Leo are put in the chamber with the students, while Daniel is pulled out. Giselle's chamber burns out the chips of Chase, Adam, Bree and the students, destroying their bionic abilities. Because Leo does not have a bionic chip, he is able to break everyone out. Giselle attempts to use her electric whip to destroy Chase, Adam, and Bree, but her attack misses and instead cuts her in pieces. Meanwhile, Marcus tortures Daniel in front of Douglas, and after Douglas' failed attempts to turn Marcus to their side, Daniel replicates Marcus' bionics to blow Marcus up. The team returns to Davenport's lab in Mission Creek to restore the bionic chips. Davenport and Douglas reveal that they have created one universal bionic super chip, so they would all get the upgrade. Douglas also reveals that he brought Marcus' parts from Giselle's lab, and he expresses his desire to rebuild Marcus and reprogram him to be good, but everyone disapproves. Tasha reveals that she is pregnant with a girl. Perry shows up and reveals her relief that everyone is okay. While everyone else leaves the lab, Leo stays behind and notices that Marcus has regenerated himself. Douglas shows up and melts Marcus with a weapon. Later, as Chase, Adam, Bree, and Leo are packing to go back to the academy, Davenport tells them that he is splitting them up. It is decided that Chase and Bree will stay with Davenport to work on a new team project, while Adam and Leo will go back to the academy. When Adam and Leo leave, Davenport asks Chase and Bree if they are ready to start their new adventure.
