I won't get too deep into this, but after some thought, I seriously might suggest Arceus (Crazy, but it could work).
(B): Punishment:
He sends black and purple spears to strike downwords from a black hole above the character space next to him. The spikes go 2 1/2 character spaces upwards. If the opponents % is higher then Arceus's, they'll recieve less knockback. However, if they are healthier than Arceus, then they'll receive more knockback. The DMG is darkness.
(B)>: Earth Power:
He blows up thr ground 1 1/2 character spaces next to himself. If anyone is caught in it, they're auto pitted. It takes one 1/2 second recovery for Arceus. The time that the opponent is pitted depends on the % of the opponent. Anyone near the edges of the earth power will hit a sweet spot, take damage, and be slammed upwards.
(B)v: Cosmic Power: Light force gathers around himself. the energy draws in opponents. If one of the opponents gets caught in it, they get stuck, then Arceus releases the energy, and they are shot left or right, at 50/50 chance. This move does alot of damage. However, Arceus can be hit by projectiles in this phase, and it takes him 2 1/2 seconds to get out of it.
(B)^: Gravity: He starts floating, and electricity covers his enitre body. If anyone physically attacks them, they are shot away with double the damage they would of previously done. When he grabs the edge, he doesn't, but instead, floats on the top of it, and recieves no dmg from anyone with super armor, and when he lands on the edge, he shoves then opponent away with wind.
FS: Judgement:
He teleports to the center top of the screen, then shouts, "PREPARE... FOR.... JUSTICE!!!" and then he fires red beams from his head upwards. The enitre screen is then hit by diagonal-falling meteors of light. Like Ness's FS, but at then end, he'll kill anyone on any floors by having a beam of light (Judgement) fly across it. Each are 1/2 character spaces wide. Proabability of killing: 89%.
I'll work on (A) moves latar, revolving around the plates.
