CAMMY: After Guile's demise from the army Cammy became depressed and started to drink alot, this led her to very weird places like the world -1 from Mario Bros or those stages that werent used in Streets of Rage 3. One of those places was an old Shadaloo base which Bison abandoned long time ago, however some of the stuff was still dangerous on that place but Cammy was so drunk that she didn't care and so started to search for beer or something with alcohol (Or alcohol itself). She eventually found a weird cup with yellow liquid inside, she tought "Oh! Some Budweiserrrrrrrr" and drank it. That was in fact a rejected experiment Bison's henchmen did with Ryu's DNA, that liquid's function was to transform the one who drinks it into Ryu (Minus the head, yeah clothes conveniently appear from nowhere). And so Cammy becomes a shoto. What's the destiny awaits for her now? Who knows, some people believes she commited suicide but she's so drunk she didn't realize she's dead yet, some others says she's training to enter on the next Street Fighter tournament, some others says she decided to train with Rikard's disciple SPO RYU in order tp become the best shoto ever...
