Soul Fist 
+ P (can be done in air) 
Morrigan shoots a projectile which looks like a skull covered in flames.  In the air, it moves at a downward angle(a la Akuma, but a little steeper) and pushes her up, so it can be thrown multiple times.  It can't be blocked low.  

Shadow Blade 
+ P (can be done in air) 
Morrigan's strikes out with one of her bat wings, which has a blade-like appearance.  This move hits multiple times and is very similar to Ken's shoryuken.

 Vector Drain 
+ Fierce (close) 
Morrigan grabs her opponent, then flies up.  She then smashes her opponent down into the ground headfirst.  Does a good amount of damage. 

Shell Kick 
Jump in air,  + Roundhouse 
This is exactly like Wolverine's downward kick.  It should be used as a surprise attack and not to often because if it is blocked, it leaves you vulnerable.  
 

 Super Moves  

Soul Eraser  
+ PP 
Morrigan summons many bats together, which form into a large cannon.  Morrigan then fires one thick beam of light and two medium beams of light at her enemy.  This super does an UNBELIEVABLE amount of damage.   

Silhouette Blade 
+ PP 
Morrigan summons Lilith, who performs multiple shining blade attacks.  Is different from Ken's and Akuma's Shoryureppas, because Morrigan doesn't do the attacking.  This is Morrigan's only comboable super, so be prepared to use this one the most. 

Darkness Illusion 
+ KK (can be done in air) 
Morrigan flies forward, and if she connects, a double of her appears on the side of the opponent and both unleash a can of whoop-ass on him/her!  Does an excellent amount of damage, but is blockable. 

Eternal Slumber 
Jab, Forward (Kick), , Strong, Roundhouse (level 3 only) 
Morrigan and Lilith fire a tiny heart which travels across the screen.  If it connects, a pink curtain falls over the screen and Morrigan proceeds to have...uh... an enojayble experience with him/her.  It can be canceled with a projectile or evaded by super jumping.  I would not recommend using this super because Soul Eraser takes off more.  Use this only if you are playing against a scrub or are up a life meter.
