Former baddies that become good (excluding Vegeta)

As a homage to Daizenshuu EX's topic, which evil guys except Vegeta that didn't turn good in the manga/anime/games would you like to be good? (this topic does NOT include Cell, who was good in the arcade game, nor Dabra from filler, nor Saibaiman from the DBZ3 story)

I'll start

Raditz & Nappa - One is Goku's brother, while the other is a mindless idiot, both less evil than Vegeta
TaoPaiPai - Specially as a cyborg, i would like him to became good
Freeza - A being less evil than the SSJs, however if he survived to movie 8, i bet he would act worsed than Vegeta did, upon seeing Broli as a LSSJ
Tullece - Even thought Toei would make "Evil Tullece" just as Tullece is "Evil Goku", it's a shame he got killed off, he could've been a perfect ally in the movies
Shu and Mai - Future Mai already changed, so why not Shu? They're not true villains, more like comical villains
Tambourine - Even thought i like his role as a devil, he could of beg for mercy
Future Lazuli - She wasn't so bad, sure she killed humans, but who cares? (also Lazuli never touched Gohan in the manga, Lapis killed him)
Bido, Bujin and Zangya - It's a shame those 3 got killed off, Bojack can go to hell, and Gokua, well he was weak and Trunkie killed him
