Vega probably just drops this entire thing, maybe tries to sell the SIN data to the highest bidder, make himself rich or some shit, enjoy life in a house full of mirrors
Balrog can’t get into boxing anymore since is permabanned so he’ll probably keep being the thug for hire, as Shadaloo isn’t the only criminalistic organization in the world
Sagat can finally erase all the memories and burn all the bridges that tie him with Shadaloo, continue living his peaceful life
The US Military probably once more becomes the biggest force in the world, now free from the governmental corruption under the influence of Shadaloo and its offerings
Chun’s father and Nash’s betrayal are avenged once and for all, both now can go on living, unless Charlie dies like a bitch he is
Guile will probably retire and go home to be a family man
Birdie will probably remain as Karin’s living exercise device, nigga found his heaven full of free food which is basically all what he needs right now
FANG will most likely either continue to work on his projects that he’ll keep to himself after the fall of Shadaloo since he won’t exactly have the equipment to work on them, or maybe attempt to resurrect the Nguuhao syndicate
Ed, if not captured/contaminated, will probably be targeted by Bison to move his soul into his body since they both possess Psycho Power, or by Illuminati to study him and use him for their own purposes (maybe that’s how Twelve/Necro projects come to be by SF3 era)
Cammy will finally save all the dolls (or they will tragically die and Cammy will have to make a sacrifice once more to forever rid the world of Shadaloo and its presence) and they will all live a happy fourteensome lesbian life in a house full of cats
Juri might find her place in the world after the destruction of Shadaloo since she won’t quite have a reason to follow the Dolls or Cammy anymore now that they aren’t useful to anyone and freed from their brainwashing. I’d assume she could join the Illuminati ranks. Imagine the Urien x Juri partnership/relationship! OOMPH!
Abel will finally find his answers as to how he was created and find a purpose in life, and being a part of the Hero team and knowing both Charlie AND Guile by now - maybe he’ll join the military ranks, don’t think he can live otherwise since he has no family at all
Viper will just be on her different mission now that she won’t have to investigate Shadaloo anymore, or maybe go back to watching after her daughter like a proper parent
Rolento’s army gets rid of basically their biggest rivals and maybe he will be preparing to create this utopia he’s constantly babbling about (wasn’t his plan to create some sort of a country or nation or something along the lines of?)
Everybody else in the cast don’t quite have any tie-ins to Shadaloo as we’ll be slowly moving into the Illuminati arc
