The Viking Raiders

In 2014, Hanson and Rowe participated in the Top Prospect Tournament,[4] where they met in the finals. Hanson defeated Rowe to win the tournament[5] Since then, they performed as a tag team under the name War Machine. On April 11, Hanson and Rowe both signed contracts with ROH.[6] On August 22, 2015, War Machine defeated Killer Elite Squad (Davey Boy Smith Jr. and Lance Archer) in a non-title match and afterwards challenged them to a match for their GHC Tag Team Championship, a title owned by the Japanese Pro Wrestling Noah promotion.[7] War Machine received their title shot in Japan on September 19, but were defeated by the Killer Elite Squad.[8] On December 18 at Final Battle, War Machine defeated The Kingdom (Matt Taven and Michael Bennett) to win the ROH World Tag Team Championship.[9] They lost the title to The Addiction (Christopher Daniels and Frankie Kazarian) on May 9, 2016, at War of the Worlds.[10] In late 2016, War Machine took part in New Japan Pro Wrestling's 2016 World Tag League, where they finished with a record of four wins and three losses, failing to advance to the finals.[11] Hanson and Rowe debuted for the United Kingdom based Revolution Pro Wrestling in January 2017, unsuccessfully challenging Joel Redman and Charlie Sterling for the Undisputed British Tag Team Championship.[12]

On April 9, 2017, at New Japan's Sakura Genesis 2017, War Machine defeated Tencozy (Hiroyoshi Tenzan and Satoshi Kojima) to win the IWGP Tag Team Championship.[13] They lost the title to Guerrillas of Destiny (Tama Tonga and Tanga Loa) on June 11 at Dominion 6.11 in Osaka-jo Hall,[14] regaining it in a No Disqualification match on July 1 at G1 Special in USA.[15] They lost the title to Killer Elite Squad in a three-way match, also involving Guerrillas of Destiny, on September 24 at Destruction in Kobe.[16] War Machine finished with ROH at Final Battle on December 15, 2017 and on December 16, 2017. They had their final matches with NJPW on January 4, 2018, at Wrestle Kingdom 12, and January 5, 2018 at New Year's Dash.[17]

On January 16, 2018, Rowe and Hanson signed a contract with WWE and reported to the WWE Performance Center.[18]

During a TV taping before NXT TakeOver: New Orleans, Rowe and Hanson debuted as faces, now under the name "War Raiders", interfering in a match between Heavy Machinery (Tucker Knight and Otis Dozovic) and Tino Sabbatelli and Riddick Moss, causing it to end in a no contest. Over the following weeks, they started a winning streak, defeating NXT teams such as The Mighty and Heavy Machinery. On the October 17 episode of NXT, they challenged The Undisputed Era (Kyle O'Reilly and Roderick Strong) for the NXT Tag Team Championship, but won by disqualification after Bobby Fish attacked them with a steel chair; thus, they did not win the titles.[19] War Raiders would go on to main event NXT TakeOver: WarGames II in Los Angeles teaming with Ricochet and Pete Dunne against The Undisputed Era in the WarGames match. At NXT TakeOver: Phoenix, Rowe and Hanson defeated The Undisputed Era to win the NXT Tag Team Championship. They successfully defended their tag team championships at NXT TakeOver: New York against the team of Ricochet and Aleister Black.

On April 15, 2019, they debuted on Raw as "The Viking Experience", with Rowe and Hanson now called "Erik" and "Ivar".[20] This new name was very negatively received on social media.[21] Pro Wrestling Insider reported that another name considered was "The Berzerkers".[22] They teamed with The Revival to defeat the team of Aleister Black, Ricochet, Curt Hawkins, and Zack Ryder. The next week, the team was renamed "The Viking Raiders" while their finisher was renamed to "The Viking Experience".[23] They relinquished the NXT Tag Team Championships at the May 1 NXT television tapings (aired May 15). After relinquishing the championship, however, The Viking Raiders were challenged to one final NXT match for the titles by Street Profits. The match, however, ended in a disqualification after The Forgotten Sons attacked Ivar, followed by an ensuing brawl between the teams.[24]

On the September 9, 2019 episode of Raw in Madison Square Garden, The Viking Raiders saved Cedric Alexander from The O.C..[25] On the October 14 episode of Raw, Erik and Ivar captured the Raw Tag Team Championship from Robert Roode and Dolph Ziggler, becoming the first tag team in history to win tag team championships in ROH, New Japan and WWE.[26] However, they suffered their first loss as a team in WWE at Crown Jewel in a tag team turmoil match for the WWE Tag Team World Cup, ultimately losing the last match against The O.C. At Survivor Series, they defeated The New Day and The Undisputed Era in a champions triple threat tag team match, scoring Raw's only victory at the event, which was ultimately won by NXT. On the January 20th episode of Raw they lost the titles to Seth Rollins and Buddy Murphy ending their reign at 98 days.[27] On the May 4 episode of Raw, The Viking Raiders defeated The Street Profits in a non-title match. In the following weeks, The Viking Raiders would feud with The Street Profits as they faced each other in several competitions such as basketball, axe-throwing, golf, bowling, and a decathlon which was later dubbed as the "Anything You Can Do, We Can Do Better" series. A running gag in these segments would see the women involved in the competitions flirting with Ivar and ignoring Erik much to Erik's disgust. The series would end with a 3–3 tie between the Street Profits and The Viking Raiders.[28] This led to a match scheduled between the two teams for the Raw Tag Team Titles at Backlash. However, the match never began as The Street Profits and The Viking Raiders brawled backstage which also saw them work together to fend off Akira Tozawa and a gang of ninjas on motorcycles. The Street Profits and The Viking Raiders continued brawling afterwards until they fell into a dumpster.[29] On the June 22 episode of Raw, The Viking Raiders finally received their Raw Tag Team Title match against The Street Profits where they were defeated.[30]

On September 7, 2020, on Raw, The Hurt Business defeated Crews, Ricochet, and the Raiders in an eight-man tag team match, with Alexander scoring the pinfall over Ricochet, with the match being forced to an abrupt ending due to Ivar suffering a legitimate cervical injury during the match.[31][32] On September 14, Ivar underwent successful surgery to repair a neck injury thus rendering him out of action and putting the team on hiatus.[33][34]
