The only thing I can't figure out how to make look right are Registeel's legs. I can think of a few characters where I can probably get everything else to look pretty good but all of their legs are too long. Do you have any suggestions for who you'd want him over? Here's some pros and cons of some different characters I've been thinking about for him:
Bowser:Pro: His got a really wide body and pretty short legs
Con: His shell might be hard to make look right, his arms are a bit short, and my slots are full
Donkey Kong: Pro: His moveset would fit the regis pretty well and he has wide shoulders and long arms so I think I'd be able to make their bodies pretty well.
Con: His legs would be too long
Wario:Pro: His body is round, his legs are short, and I already know that you can remove his head fine because of Gengar.
Con: His arms are probably too short, he'd need a size mod, and his moveset is completely wrong.
Metaknight: Pro: He's already a ball and has short legs
Con: He's pretty small and has no arms
King Dedede:Pro: He's round and has short legs
Con: He'd have to use a hammer, his feet act weird, doesn't have fingers, and it might be hard to shape him right
Samus:Pro: She's metalic and has a pretty fitting moveset
Con: Legs are way too long and her body is probably too thin
As for Lopunny, I think that she'd probably work best on Lucario if I was to make her.
