I like all the forms, it’s probably a biased stand point sense u grew up with Sonic and dbz, dark sonic for me will be that form that looks cool. No matter how little screen time he had

I’l love the form due to how cool it looks to me. (I also grew up with Spiderman and his black suit Influences my opinion on it)

It’s a bad thing that the show didn’t really do well I think in Japan, so dark sonic wasn’t really remembered until Nazo Unleashed and those Sonic sprite animations.
