Hanson has created numerous animated web series on his Egoraptor YouTube channel, including The Awesome Series, in which he parodies various video game franchises, including Pokémon, Metal Gear, Ninja Gaiden, and Final Fantasy, as well as for Sequelitis, a series of animated video essays in which he comedically and critically compares the quality of a video game and one of its sequels. He has also done voice acting for various shows such as Rick and Morty, Mighty Magiswords and Cyanide & Happiness, and video games such as Dragon Age: Inquisition and Detective Grimoire. He regularly collaborates with Ninja Sex Party, a musical comedy duo consisting of his Game Grumps and Starbomb partners Dan Avidan and Brian Wecht, providing guest vocals for their albums and appearing in their videos.
Arin Hanson was born and raised in West Palm Beach, Florida. He attended Wellington High School in Wellington, Florida, for two years. Not given a schedule of classes for his junior year, he was informed that since he had moved, he could no longer attend Wellington High School. Instead of continuing at the new school, his mother allowed him to drop school entirely, leading him to pursue voice acting. Hanson later moved from South Florida to Los Angeles to pursue a career in voice acting.
Hanson first joined Newgrounds under the name of "Egoraptor" on September 16, 2001. After joining, he submitted his first Awesome animation, "Metal Gear Awesome," on February 23, 2006. Hanson went on to upload various comedic video game-related animations, as well as four separate animated webseries (of which he then uploaded to YouTube); Awesome, short animated videos that parody video games, Lemon 'n Bill, a comedic series in which an anthropomorphic bullet and lemon get trapped within video game worlds, Girlchan in Paradise, a parody of shōnen anime, and Sequelitis, a series in which Hanson compares a video game and its sequel along with minor animations throughout the video. Hanson was also an early storyboard artist on the show Axe Cop.
Due to the success of "Metal Gear Awesome," Hanson was approached by MTV to produce animated shorts in the style of "Metal Gear Awesome" for MTV's online video gaming show, The G-Hole. MTV gave Hanson four guidelines: the shorts must be poorly drawn, the shorts must have violence, the shorts must have swearing, and the shorts must be 30–40 seconds long. MTV also restricted him from submitting these movies to anywhere but The G-Hole, a restriction which Hanson constantly fought believing that all of his fans should have easy access to his work. He went on to create 1 to 3 Awesome episodes a month for The G-Hole before the show was put on hold and eventually canceled. Awesome continues online, on Hanson's YouTube channel.
In 2011, Hanson provided the animation for the unreleased game JForce: Unstoppable. The game was set for release in 2012 with a Kickstarter to help fund the project, however the project was unsuccessful having only raised $1,441 of its $10,000 goal. Hanson would later go on record stating that he was ashamed of it and that he only took the job because he was broke at the time.
In 2006, Hanson provided the voice of Bruce Banner in the video game Marvel: Ultimate Alliance as part of a competition held by Activision. His voice went ultimately unused and the character was played by Robin Atkin Downes, though VGFacts, Hanson's own website, and the credits of the game claim that his voice was used in the Wii port. In 2009, Hanson provided the voice for the character John Gore in the video game Minigore, and later reprised the role in the 2011 remake of Death Rally.
In 2012, Hanson provided his voice for the game Detective Grimoire, a Kickstarter project which was successfully funded on August 3, 2012. Hanson has also provided his voice for Dragon Age: Inquisition, Target Acquired, Red vs. Blue, Cyanide & Happiness, and Rick & Morty. Hanson is a recurring voice actor in the Cartoon Network series Mighty Magiswords playing the role as Gateaux, Morbidia's partner whose voice is based on George Takei and often repeats the last word she says. ? His recognition as Gateaux gained the series a cult following. He also does some additional characters such as Delivery Man Steve, Fibby Croax, Zonq, The Praying Mantis and Birda. Grumps co-star Dan Avidan sings the theme song for the series with creator Kyle Carrozza.
In late July 2012, Hanson and his colleague Jon Jafari, known for his video game critiquing webseries, JonTron, created a joint YouTube show, called Game Grumps. On this show, both Hanson and Jafari played video games that were typically retro or nostalgic in style. In late June 2013, just under a year after the show's inception, Jafari left Game Grumps to focus on his own channel and was replaced by Dan Avidan of the band Ninja Sex Party, who continues to work on the show to date.
Apart from the YouTube series, Game Grumps moved to live performances at Hollywood Improv in late March 2016. Completely sold out, the event led to future performances in New York and other locations on the East Coast.
In February 2012, Hanson appeared as a contestant on the Sony game show, The Tester, during its third season, as a community-voted contestant, but was eliminated in the third episode after being accused of using the show to promote himself. When asked about his experience, and whether or not he would do it again, he replied negatively. Many defend Arin Hanson, saying that The Tester used his popularity to get more views on Sony's YouTube channel, and that the judges were unfair to him. Hanson appeared as a contestant in the third season of the dance competition webseries Dance Showdown, alongside professional dancer, Maxine Hupy. Hanson was announced the winner of the season. Hanson has also done narration work for several episodes of Did You Know Gaming?, a webseries dedicated to video game trivia, including episodes covering Star Fox, Grand Theft Auto, Super Mario, Mega Man, Pokémon and Kirby. He also talked about the development of Jurassic Park on the show's spin-off Did You Know Movies, on MatPat's channel "The Film Theorists." Besides providing additional work for online series on YouTube and Newgrounds, Hanson has been featured in several videos for the website ScrewAttack, including a collaboration with James Rolfe and Keith Apicary. In 2008, Hanson worked together with Ross O'Donovan on the animated webseries Gamer Tonight where he provided the voice of the host, which was broadcast on the Australian television show Good Game. As of 2015, Hanson has been working with O'Donovan on a reboot of O'Donovan's Gameoverse, doing writing and voice work, primarily.
In 2013, Hanson provided vocals for the track "Knight in Shining Armour" by Dougal & Gammer released as part of the compilation Clubland X-Treme Hardcore 9.
In 2013, Hanson, along with Game Grumps co-host and Ninja Sex Party singer-songwriter Leigh Daniel Avidan and instrumentalist Brian Wecht, formed the band Starbomb. They released their first album, eponymously named Starbomb in December 2013. Starbomb went on to release their second album one year later December 2014, titled Player Select.
On April 15, 2014, FAT REFUND, a rap song, was released on the channel StamperTV, a collaboration between several animators and voice actors including Rice Pirate, Marc M., Stamper, and Hanson himself.
