pfft this fool knows nothing of Akuma. Scorp said it right Akuma does not do the Shinkuu-hadouken (Vacuum Surge Fist).
Akuma performs the Messatsu Gou Hadou (Destructive Murderous Great Surge) Down Back 2p. Same as Shinkuu Hadouken except with purple Ki and it's weaker and the time is
shorter.

Looks like Evil Akuma got banned.... Probably from posting double or triple a lot. *tsk tsk*
