Now i am pretty sure that Sakurai has revealed some characters that will be unlockable. If i have to guess his moveset, his abilities and weapons (from the Kirby games) include:
- A giant Mallet
- The ability to inhale, stronger than Kirby's (no copy ability though)
- The ability to inflate himself (just like a balloon), and bounce -he cannot fly with this.
- The mallet's head seems to come off and explode (Kirby's Dreamland 2)
- He can do a Super Jump and Drop with great force (a la Bowser and Yoshi)
- He can become super-angry (Kirby's Dreamland 2), venting vapor and powering up his abilities.
Final Smash that i'd like: DDD is possessed by DarkMatter (Kirby's Dreamland 2 and 3, Kirby and the Crystal Shards) allowing him to float in the air, and shoot orbs of Dark Energy. He also has a may where his belt normally is.
