Goten and Trunks from DBS (and their subsequent fusion Gotenks). In the Buu saga, and Fusion Reborn, they were cool kids. Now they've kinda just devolved into this gimmick where they show up, and the adults say "This isn't a kid's fight" (while completely ignoring the fact Gohan fought the saiyans and went to namek at 5, and beat cell when he was 9). I wouldn't say I hate them, but whenever I see them I'm really just disappointed.
