Fnatas 1: you are playing as mallie, and daisy is the one controlling the animatronics that tries to kill you
Fnatas 2: you are playing as raven, and jaiden is the one controlling the animatronics that tries kill you (i don't know why jaiden wants raven dead)
Fnatas 3: you are still playing raven, springgirl is the same as mallie, she just wants raven (i think she would still love him even if it requires him being dead) the phantom is... Well phantoms
Fnatas 4: where all started, you play as mallie, of course, daisy is the one controlling the animatronics, 
Fnatas 5: you play as daisy and you are fighting your nightmares
