if you are coming from smash bros then pepper is like sheik.keke is steve(kinda).Vsage is just broken,and sanbad i think is just a swordy idk i dont really like him.
I've noticed 2 characters that vg sage derives his moveset from, being palutena for his d-tilt, nair, and staff, and Bowser for his up and down specials. He also gets his neutal special from falcon and ganon, and his side special from the star fox gang
