M. Bison, clearly. She was created when Bison separated the good half of his soul from his body, he trained her, and then she left him because she doesn’t condone evil acts.
^ From what I’m hearing, her being the good half of Bison’s soul was actually a mistranslation on the West’s part. In the intended canon, she may have just been a former pupil of Bison who rebelled once realizing his evil ways.
Oh, ok. Because if people were playing Smash or Pass and Rose was canonically made from the good half of Bison’s soul, they would say Pass because she was created from a man’s body. So, that would mean she’s half a man and half a woman. Lol 😂
^ From what I can gather the official canon is just a mix of both. Rose was naturally born but it also turns out Bison transferred a portion of his soul into her. Simply put, the way she uses Soul instead of Pyscho Power still makes her function as the good half of Bison.
