Ngl I can argue that M. Bison is a better villain being that for over 20 years of the timeline, he has mental abused half of the characters in the franchise, caused sum to die, died two times and yet came back, controlled an organization but given that gill said He let all of this happen because he knew the outcome is kinda badass though
Controlling ryu, ken, killing chun li’s dad, turning blanka into whatever he is, killing Charlie causing guile to enter a depressive state, I’m not even gonna get started with cammy, and the list goes on
Of course he is the great one The one who will save humanity The one who will take humanity to the paradise The great red blue yellow haired boiiii My boiiii Gill is for me one of the best street fighter characters
