Tons of Final Fantasy/Kingdom Hearts characters like Tidus, Lulu, Squall, Amarant, Freya, Ifrit, Ansem, etc..
Lots more Pokemon like Genesect, Zekrom, Sneasel, etc...
Anime characters like Kamina, Love Machine, Byakuya Kuchiki, Solf J. Kimblee, etc...
And a ton of other random characters like Venom, Blanka, Laharl, Violator, other Dynasty/Samurai Warriors/Sengoku Basara characters, other wrestlers like The Rock and HBK, etc...
There are a lot of reasons I'd go with Wolf over Charizard. The first reason is that Charizard's proportions aren't nearly humanoid enough (his limbs are too short and his neck is way too long). Honestly, even Wolf's legs are too short. The second reason is that (other than a few moves like his blaster and Final Smash) Wolf's moveset fits much more than Charizard's does. Even in just the way he stands it looks like it fits Alien Well. The third reason is that there are so few Wolf vertex hacks out there.
