How about...
Ragna or if you're only thinking female then
Noel VermillionMayhaps one of these you'd want to start next? Just trying to help out lol.
I would Say Ike and ZSS
I came up with a few more. Some are not Zelda
I'm just trying to fill you up...with ideas >. >
Ganondorf^ Theres one for Falcon but Ganon actually has a hand of purple energy like Bison.
This is a bit of a strech idea...but The Ippo hack for Shiek(By Ike L)
You could turn him into Dudley, one of my faves from Street Fighter (Balrog/Boxer works too)
Back to Zelda Ideas
This may not be the GREATEST idea but I think it would be fun.
...This would be very interesting to see.(I need to see this....someday)
