After graduating from Corpus Christi, O'Donovan studied and instructed animation at the Film and Television Institute of Western Australia in Fremantle, Western Australia. O'Donovan's best known work is the series Gamer Tonight, which is voiced and co-written by animator Arin Hanson, and was produced for the ABC2 video game-based program Good Game. The series features a fictitious talk show called Gamer Tonight with Richard Farkas, whose host would interview various types of gamers. He also created the showGameoverse, which featured Hanson in every speaking role. Gameoverse has since been put on hiatus, though O'Donovan has confirmed the series will return. O'Donovan started animating on Newgrounds, under the name "RubberNinja." He then moved his animations to YouTube, but as a result of not being able to keep the username RubberNinja, he went under the name "RubberRoss." In January 2014, he received possession of the name RubberNinja, and uploaded a video on his old channel telling subscribers to transfer over to his new one. This video has since been removed. In 2016, O'Donovan and Conrad were invited to Conrad's alma mater, UC Santa Barbara, to discuss their careers on YouTube at the Graphic Voices conference hosted by student organizations at the university.
''Game Grumps''
After Jon Jafari's departure from Game Grumps in 2013, Hanson launched a second show on the Game Grumps platform, originally conceptualized by O'Donovan, called Steam Train. This would replace a then-empty timeslot. Ninja Sex Party vocalist Dan Avidan joined O'Donovan as co-host of the show, where both play PC games. This broadened the channel's output to three videos a day: on average, two standard Game Grumps episodes, and a single Steam Train episode. With the introduction of the show's second season, the parameters of Steam Train were expanded, allowing for O'Donovan and any member of Game Grumps to co-host. In addition to this, O'Donovan has acted as a co-host of other shows from the Game Grumps platform, including Grumpcade, Steam Rolled, and Hunting Monsters. O'Donovan was also a frequent guest on Table Flip. He has also authored multiple content-related animations for Game Grumps Animated.
Personal life
Ross Kenry O'Donovan was born on 17 June 1987 in Perth, Western Australia to Irish parents. He graduated from Corpus Christi College. His sister Rebecca is a journalist in Australia, and is married to Australian cricketer Shaun Marsh. On September 29, 2012, O'Donovan married Holly Conrad, a cosplayer, propmaker, and special effects artist who was featured in , as well as Heroes of Cosplay. On September 19, 2018, Conrad and O'Donovan announced on their respective Twitter pages that they would be splitting up amicably due to reasons connected with Conrad’s recent move to Seattle.
Charity
In June 2015, O'Donovan launched a 5-episode miniseries, released on the Game Grumps channel, called Guild Grumps. O'Donovan mentored 4 members of the Game Grumps crew in a 5-day race to advance from Level 90 to Level 100 in the Warlords of Draenor expansion of World of Warcraft. Each participant had $1,000 to donate to a charity of their choice, if they reached the goal. If they did not, their donation would be split between those who won. In the end, O'Donovan was the sole winner, and, combined with the participants' distributed funds, donated $5,000 to cancer research. As of 2015, O'Donovan and Game Grumps have raised over $70,000 by hosting charity livestreams on Twitch.
