Akuma and M. Bison didn’t meet until the end of SF2
This requires some knowledge of Street Fighter lore. The only time that Akuma and M. Bison met was at the end of the World Warrior tournament in the second game. It’s canon that Akuma performed the Raging Demon on Bison and killed him. They didn’t meet in a cave and interact there. Ever.
Balrog isn’t a PC whiz
Balrog is canon to care only about getting paid while in the service of M. Bison. There is no way that he was doing any sort of IT monitoring or PC services for Bison. Also, there is no way that he could perform any sort of typing with boxing gloves on. It’s physically impossible.
Cammy and M. Bison weren’t lovers
OK, this is sort of confirmed to be kind of true because Bison had her brainwashed to believe that she was his lover previously. However, the ick factor that accompanies this also requires some knowledge of SF canon. Official word from Capcom is that Cammy is a clone body created for Bison. He’d be making out with himself.
M. Bison and Guile aren’t friends
There is never a time in SF lore that M. Bison and Guile were ever friends or helped each other. Never. M. Bison personally murdered Guile’s best friend, Charlie Nash, in Street Fighter Alpha 3, which takes place before Super Street Fighter II Turbo. Guile’s vendetta is solely based on this. This frame never happened.
Zangief never worked as a Bison minion
The only adaptations where Zangief worked for Bison was in the live-action movie and in Street Fighter II V, neither of which are considered canon. He usually is friendly with the other World Warriors, save Guile, who is one of his motivations to defeat. Given that the cartoon is based on the live-action movie, that’d be why, incorrectly, Zangief is shown to be a henchman.
