there is no items but moves the back character can do

attack moves

special moves (like you gives yourself a buff or give the enemy a debuff)

and defending moves

you can swap characters while driving

also minor thing but each character pairing would have a team name ya know for the funnies

(ei kris and susie "Apple @!@#%ers", ralsei and susie "marshmallow Trashers", kris and ralsei "... ralsei")
