Right, I feel that Trunks found peace after he defeated the androids and Cell and devoted his time to rebuilding society rather than training for the next potential threat. That's a trait we've seen from the mature half saiyans. Gohan and Trunks aren't fighters like Goku and Vegeta. Even if Trunks maintained the strength he gained from training with Vegeta in the passing years it wouldn't be enough to stop Black, rage boost or not. It wouldn't make sense for them to introduce a new villain if he wasn't a threat. i wouldn't say Akira sucks Goku's dick too much either..Goku is the main character. Dragon Ball is about Goku's life lol, though, it does seem all non full-saiyan characters have basically turned into cheer leaders. I don't like how DB has like 5+ other characters that are still included but can't really contribute at all anymore.
Yeah, tell me about it! Fine Goku and Vegeta are the strongest ones but still Akira should make use of the old cast like you say. It would be nice if the sayin race could get a challange from the other races. Like if Piccolo can train with piikon and discover some new stuff that the nameks can do.(even though Pikkon is not a namek) Or somethink like that! The same goes for the humans. What do u guys think ?
