Ross O'Donovan

After graduating from Corpus Christi, O'Donovan studied and instructed animation at the Film and Television Institute of Western Australia in Fremantle, Western Australia.[2] 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.[3] The series features a fictitious talk show called Gamer Tonight with Richard Farkas, whose host would interview various types of gamers.[4] He also created the show Gameoverse, which featured Hanson in every speaking role. Gameoverse has since been put on hiatus, though O'Donovan has confirmed the series will return.[5] 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.[6]

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,[7] 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 (the title references the retailer Steam). 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 (as opposed to only Avidan).

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.
