How do I give a character a secondary mode?

Okay so my question is pretty straight forward so here's an example of what I am going to ask about.

 

(Selecting Character)

"Ryu + (holding) ENTER = Evil Ryu"

 

What I wanna know is how can I make it so I can do that with other characters that are related to each other like let's say Boryema's Goku and Super Saiyan Goku, I have already moved Super Saiyan Goku's files and folder over to normal Goku's so what else do I have to do to get the end result of..

 

"Goku + (holding) ENTER = Super Saiyan Goku"
