Misused Dragon Ball characters that had potential
Who are some characters who were utterly wasted in your opinion? I'll name a few:
Dabura could have been a main villain as the "Demon King", considering he's the the ruler of the Demon Realm. Instead, he's just a lackey of Babidi who couldn't outmatch an adult Gohan who neglected his training.
Kibito Kai looked cool as the first potara fusion, but never had a chance to fight.
Some people think Nam from the original Dragon Ball series should have had the chance to become a Z-Fighter. Yajirobe too, although he kind of was one during the Saiyan/Vegeta Saga.
