Milk Spoils the Battle
Down-B: Drinks a glass of milk and regains a little health, it can only be used a few times before it goes on a cool down
Side-B: He dives to the side, holding a lit grenade, it goes off and damages him and anyone else around him.
Neutral-B: He reaches into his special nonexistent bag and pulls out either a rocket launcher, a minigun, an assist trophy, a laser sword, or a nuke. The nuke damages him and a large area around him, and goes off instantly. The rocket launcher will propel him the opposite direction he's facing.
Up-B: The Spirit will leap out of the carton, turning it into a normal carton, and fly upwards, before possessing another carton. Sometimes it won't be a carton, and will be other things, like an empty fairy bottle, or a bucket of Milk from Minecraft.
Ultimate Smash: *he dashes in front of him, and anyone in front of him will fly into another reality, and The Spirit will exit Milk, then enlarge. He shoots a giant beam at the enemy and the screen zooms out to the solar system, the galaxy, the universe, the omniverse and then the reality itself, as the entire reality explodes into nothing. They're then taken back to the battlefield
