Sideswipe is hot-headed, eager for battle, and even more eager to get out from the shadow of his brother Sunstreaker. He's forever got a chip on his shoulder, and isn't shy about taking it out on any Decepticons within head-bashing range. His insubordinate attitude and battle-lust can lead to tensions with the more peaceful-minded Autobots, but there's no discounting his courage: Sideswipe will happily wade into battle against any foe, no matter how powerful or numerous, and won't let up no matter how hopeless the odds. This combative temperament of his is probably why he gets along fairly well with the fearsome Arcee.
