I would have to say Tails, aside from being a flying fox\super mechanic (those crazy Japs) hes the only one who doesnt have a really annoying dominant trait (sonics 'tude, Shadows mysteriousness, Knuckles strange habit of changing sides faster than a drunk driver swerving on the roads, Amy's irritating "damsel in Distress" role, Im sure that Rabbit has something too, Rouges 40 year old voice, like Lisa Hayes from Robotech where shes obviously in her early 20's but sounds like shes pushing 40, and of course, Robotniks inability to forsee Sonic's intervention in his misguided plans). Tails' dominant trait, being the smart one, actually comes in Handy. I dont watch the show Im just a huge fan of the early 3d games (SA, SA2: Battle).
