I'm not sure if this would be considered a real battle, or just humor, but
Batman, Deadman, Zatanna & Blue Devil vs Richie Rich, Casper, Wendy & Hot Stuff
You've got your rich guy, Batman vs Richie Rich
You've got your dead guy, Deadman vs Casper
Then there's the magician, Zatanna vs Wendy
and then the demon, Blue Devil vs Hot stuff
and if your wish add in Alfred Pennyworth vs Herbert Cadbury
and Ace vs Dollar
