I don't mind him being cocky in the games, considering he races/fights a lot of villains who want him dead. It seems fitting for him to want to get on their nerves.
But I suppose you're right, it is a part of him. (Not exactly something I 'love' though)
Could have done without the gang up at the end though.
I'd love to see Black Shadow make it in, now that would be hype to see.
