Was this depicted in any of the games?

It looks like a bad guy.

It's depicted in Guilty Gear 2: Overture.

Headband finally fell apart, I see.

Has more then one.

So this is why Night Terror disappeared from Soul Calibur in SCIV, they put him in Guilty Gear instead.

He just releases more of his power. In fights he restrain himself to 30% with his head gear.
