>>106245728I disagree.
Robotnik is a bad man in AoStH, pure and simple, he's literally a-okay with stealing candy from babies, and abusing his own henchmen to a sadistic degree (who could forget the opening to Robotnikland?). As such he's very much deserving of getting his ass kicked by Sonic, who is generally easy-going and laid back, just wanting to chill out and eat chili dogs.
The problem with SatAM Sonic is that he is a jerk to his so-called allies, Antoine for instance, may be an arrogant berk, but he's still supposed to be a member of the resistance yet Sonic has no qualms with putting him down at any opportunity. He's also very obstinate with Sally which somewhat undermines her as a leader as well as making Sonic look doubly bad if his hunch is wrong.
Back to AoStH Sonic, he can be a dick at times, like with Captain Rescue, but that's an instance where he doesn't want the old man to get hurt doing something that's beyond his scope. Most of the time though he's just being an older brother to Tails, whom he genuinely cares about in a very honest and sweet way which has a nice juxtaposition to the radicool attitude he has.
Really, you can't watch the end of 'Full Tilt Tails' or 'Tail's New Home' and tell me that Sonic in AoStH isn't a really swell guy.
