Ok, so he now has 20 powers in total, making Wolverine the first melee character with a
huge moveset. I didn't think that was possible... (You can decide if his normal/rage switching boost should be at no energy cost, or a low energy cost. Shouldn't be high cost because he's only switching modes.)

WOLVERINE - Berzerker Version:
(1) Uses the rage system, but with a few differences. Instead of gradually gaining rage, one of his boosts will give him instant and unlimited rage at a
low energy cost. This is basically a switch between his normal mode and rage mode. It's a boost that really isn't. In rage mode, he emits red smoke on his body and the dots at his HUD are all glowing red as it usually does. His claws do not have to glow though.
(2) Obviously, the rage moves inflict more damage. So to balance it, his healing factor ability is not available in rage mode - only in normal mode. This gives players a reason to play as the normal one and not just the rage one.
(3) Normal or rage, even his melee attacks cause bleed damage. (C'mon, he has adamantium claws! If he wanted to, he could kill someone easily!)
Basically, you can do his booster the same way you did Jean Grey's (Normal and Phoenix). Keep Logan's icons and add whatever. The pics and links to pics shown are for visual aids & motivation. Here's his power moveset (
Red text = In rage mode):
Claw Slash: (Same as in-game)
Berzerker Barrage: Runs and viciously strikes opponents. Extra bleed damage. (Based on Capcom games. Replaces "Claw Frenzy" but works the same way.)

Lethal Lunge: (Same as in-game)
Certain Death: (Same as in-game. Keep the awesome skull "Certain Death" icon.)
Eviscerate: (Same as in-game)
Adamantium Lazer Blade: Wolverine slices through the space/time continuum, releasing energy comets that explode upon impact. High damage. (Based on X-Men arcade game. For fan service. Obvously Logan can't really do this, but then again Logan
isn't real at all. He's a comic character, so why not? Hopefully you've played this game and know how it looks.)

Fear: In a radial blast, Logan scares enemies into fear by growling, stunning them briefly.

Blazing Slash: In seemingly the blink of an eye, Logan speeds forward with a lethal slash that causes extra bleed damage.
Upward Slash: Logan uses both arms and slices an enemy upward. Pops up enemy.
Riot Control: Spins claws in a radial pattern whiie jumping, popping up multiple enemies.
Impaler: Stabs claws through nearest enemy, lifts him up, and slams him down hard causing radial seismic damage.
Weapon X: Slices an enemy multiple times, and finishes with a blue energy pulse that causes radial damage and knockback. (Based on Capcom games. Energy pulse is as in the picture below.)

Warrior Rage: Logan unleashes his dark side and switches to an enraged state. Costs little to no energy. Gives access to rage moves. (Use "Fury" Icon" and no animation so it's quick to perform.)(Boost)
Samurai Calm: Logan calms down and switches to his normal state. Costs little to no energy. Gives access to normal moves. (Uses no animation so it's quick to perform.)(Boost)
Healing Overdrive: Kicks his healing factor up a notch, by improving recovery speed and momentum gain. (Boost)
Killer Instinct: (Same as "Fury") plus it gives all powers high chances of instant kill. (Use "Certain Death" skull icon and "Fury" animation.) (Boost)
http://geektyrant.com/storage/post-images-2011/wolverineOrigin.jpegFeral Rage: (Same as in-game) (Xtreme)
Raging Storm: The screen turns pitch black. All that is seen is multiple fierce slashes (see the "Berzerker Barrage" pic) and blood. All that is heard are the enemies' final screams... (Xtreme)
Abilities - Might, Healing Factor (turned off in Rage mode), Blood (All melee attacks cause bleed damage.)
Grab Smash - (Same as in-game)
Damn! Now Wolverine really is the best at what he does... as he should be.
