Your description sounds pretty accurate, but adult Mario feels more... mature, and feels like he has emotion. I don't know why, but I feel like a kid Mario would be more numb than his adult self.

I can't answer the anime one very well, but I know Dragon Ball, so I'll answer that one. Goku would be happy to have him around, Vegeta would feel like he'd be a bother, Trunks and Goten would LOVE him, and everyone else is... well, up to interpretation.
