I'll give the authors credit for doing something interesting with the Final Fight franchise: using the Skull Cross gang as the main baddies. Still, I would love if instead of Bison, they could add someone else as the villain.
Like, the mod I'm doing has nothing to do with FF plotwise, but if I did, it would be somewhat of a "Captain Commando lite", with stuff like Retu (the last boss of FF2 on SNES) being a Bushinryu traitor who switched sides just like Yamato does in Captain Commando Manga, Sodom/Katana reaching enlightenment and becoming one of the good guys, even a Bushinryu ninja himself, Metro City police attempting to implement robotics on their field agents - Final Fight 3 had a subplot with a robotics enterprise smuggling firearms for the baddies, even a ridiculously "Belger revived as a Zombie" story that Capcom did with FF Revenge or the awful "dead rising meets saints row" that was Streetwise could work with a few tweaks here and there.
Like, I can get Shadowlaw/Shadaloo using thugs and delinquents in a Detroit ersatz city for a distraction, but a powerful soul bender that expelled all of his "good" energy needs some ulterior motive to have Belger (And later, Black) in charge of releasing hell on Metro City. Geese Howard did it best because Southtown was always a crime-ridden dystopia, and while the Kyokugen black belts dismantled Mr. Big's little show, Geese had to go down the Ieyasu Tokugawa's path of waiting until the person in charge dies so he can pick the CEO's chair for himself. Geese wasn't some ESPer who can body swap at will, and he faked his own death only for him to commit seppuku rather than admit defeat at the hands of Terry.
