Bumblebee at Tyger Pax
Along with Kup and Bumblebee, he suspects that something is amiss with the inhabitants of the planet Aquatron, and takes a small drops ship down into the planet's oceans to investigate. The trio is captured and brainwashed by the Quintessons, who force them to testify against Optimus Prime in a mock trial. Fortunately, they are later returned to normal and return to space aboard the Ark with the rest of the Autobots.

War for Cybertron - Autobots game
Rodimus is described as being young, impetuous, showing enthusiasm and confidence which borders on arrogance. He boldly claims that he has both skill and looks, though he is not too keen being paired with Kup on missions. Somehow, he became corrupted by Dark Energon. If the player manages to defeat him, he calms down, shrugging off the effects of the Dark Energon and returning to his regular self.
