Dio Brando

Neutral B
DIO summons his Stand, The World to do the Muda attack, much like the Capcom Game.

Side B
DIO throws his Knives at his opponents much like in Stardust Crusaders. (They cannot pass through walls.) If The World is summoned, The World will charge forward with a punch.

Up B
DIO summons The World to propel himself into the air. (Like Jotaro in the OVA.) If an opponent is in range, they will receive damage.

Down B
This will summon The World for extra range in A attacks, however, The World can only take 5 hits before disappearing where you'll have to wait 10 seconds before The World can be summoned again.

Final Smash
DIO stops time, throws two sets of Knives, and Drops a Road Roller on his opponent.
