Super Baby Vegeta
“Silver hair” reminds me of one of my favorite Dragon Ball villains. Super Baby Vegeta is the result of Vegeta being possessed by the Tuffle parasite Baby. A villain that controls your body, changes your body to fit their appearance, and can also infect and control a planet worth of people is terrifying, making for an interesting adversary. I found Super Baby Vegeta’s arc enjoyable on Dragon Ball GT. Dragon Ball GT is widely not considered canon, and this isn’t a popular opinion, but I wish it was canon because I really enjoyed a lot of things GT offered - Baby Vegeta being one of them. I hope that someday Baby Vegeta is introduced into a new canon Dragon Ball story. Regardless, I can always enjoy the character by rewatching GT or by interacting with him (or playing as him) in a handful of Dragon Ball video games.
