Arthur
Golden Armor: Activating this Hyper also gives him a shield (from what I recall playing Super Ghouls n’ Ghosts as a kid). The shield provides him 1 hit of Super Armor while active. (Shield will visibly break when Super Armor is consumed.)
Shuma-Gorath
Chaos Portal: Shuma-Gorath creates a portal on the ground in front of himself. The next character (Shuma or the opponent) who touches it falls into the portal, then reappears in midair right above the portal, briefly in hitstun if it was an enemy that fell through. Does no damage.
X-23 & Wolverine
Claws: They can retract their claws or extend them at will. While claws are retracted, normals lose their claw range and special moves that require claws will no longer work, but allows X-23 / Wolverine to regenerate red health on point (and faster as an assist).
Deadpool
I felt that Jill’s Machine Gun Spray should of been Deadpool’s Hyper, since Deadpool seems more erratic to me and would seem to do that type of thing. As psychotic as Deadpool is, his moveset seems pretty tame.
Fourth Wall Crisis: Instead of being a counter Hyper, Deadpool jumps up and immediately grabs the life bar and swings down with it. If it hits, it continues as normal. Pre-flash animation of him jumping to grab the life bar in a similar manner to Spider-Man’s Maximum Spider.
Iron Man
Smart Bomb: L and M versions of Smart Bombs bounce once when they hit the ground. L version then explodes at highest point of second bounce, while M version explodes when it hits the ground a second time. H version fires one bomb that bounces once, then it floats in the air and homes in on the opponent before exploding.
L/M Unibeam: I feel that Iron Man should have something akin to Doctor Strange’s Bolts of Balthakk. L version fires a beam from one hand, then a secondary beam with both hands. M does the opposite, beam with both hands, then secondary one hand beam. One hand beam is weaker but faster than both-hand beam. The second beam can be directed 30 degrees up or down with the control stick input if done during the first beam’s animation.
H Unibeam: H version is as a normal Unibeam, but you can hold down the button to charge it more after you input the motion.
Magneto
Magnetic Objects: Input the command, and Magneto levitates a couple (5?) metallic objects (same object as used in Magnetic Tempest) from the ground in front of him about waist high (they stay levitated for a few seconds). While they levitate, they can’t affect the opponent but they have projectile durability. When Magneto uses Repulsion / Attraction / Gravitation, if the metallic objects are levitating, the metallic objects are affected by Repulsion / Attraction / Gravitation instead and they act as a projectile. They move in a similar pattern as Magnetic Tempest.
Spider-Man
Spider Snare: When Spider-Man uses Web Zip on an enemy affected by Web-Ball, Spider-Man creates a web line that draws the enemy up and suspends them (like Rocket Raccoon’s Net Trap). They are stunned for a moment and can be hit multiple times before the web wears off.
