I was watching my friend play, he wanted to test out the TE stick, and I was telling him about all the hidden stuff in the game. We decided to venture out for the Classic Character fights...getting Classic Smoke on a random try.

I have beaten the game with Scorpion, and unlocked his Alternate Costume in the Krypt but I'm not sure if either of those effects the ability to perform this move.

Scorpions Classic Fatality is D,U,U,Y from Jump range.
