Well as being a big geno fan so this is what I think his texture should be over and the main moves

Texture over toon link

N B smash-geno whirl
Like how link has the boomerang, it would be the same

Up B smash-geno beam
Geno uses this and faces it down to give him a boost

Side B smash-geno flash
He turns into a cannon and shoots a ball of energy and can also be charged(like lucario or samus)

Final smash-geno boost
Powers himself up and fires a insta kill geno whirl(like Zelda/Shieks'final smash)
