Alright, so we've got both specials and supers here, obviously I'll start with the specials.
Specials[/i]
Diamond Spike
Summons Shiranui to launch an icicle towards the opponent, can be aimed straight, arc upwards, or arc downwards. Also rather spammable, probably going to be a main move
Shadow Lash
Gamma lashes out at the area in front of him with a tendril of darkness, relatively low damage, but it comes out fast with knockback. Works at mid-range
Ice barrier
Summons a wall of ice in front of Gamma to block any and all projectiles, also prevents the opponent from advancing past it, but does no damage whatsoever
Shadow Spike
Just as it sounds, calls forth a spike of darkness in an area. Come with three variations, close, mid-range, and far. Fairly standard special
Deathbound
Summons Shiranui to bring out a short wave of force. Slower than Shadow Lash, but does more damage with more knockback in exchange for less range.
[b]Supers
Level 1: Ice Age
A wave of Ice extends forward from Gamma, only to rise up in a burst of spikes when near the opponent. Low attack, and works at a range, however its not hard to see coming, so usually best to combo into it
Level 2: Thousand Lashes
For this one, Gamma summons two dark tendrils and begins with a single strike. If it connects, he'll then begin comboing lashes for the remainder of the super, probably doing between 10-20 hits, in spite of the name
Level 3: Frozen Tomb
Like with Ice Age, a wave of ice emanates from Gamma. This time, connecting will cause the ice to rapidly cover his opponent for the finisher.
