So I've decided to mix sprite NO BODY's YI styled Foreman Spike with SuperLuigiBros' Wario for a SMBX project (replacing Toad):
And Santa Spike just to contrast Waluigi's
I also borrowed some sprites from the gigaleak:
Bear in mind: They can't mount Yoshi's, only Kuribo's Shoes when they ride on one you can only see their heads.
Let's not forget the forgotten Jack in overalls from Wario's Woods:
All of them wearing the SMW style, celebrating both Super Mario World and Wrecking Crew (NES) so that's two birds with one stone.
