Gnar is a yordle. http://leagueoflegends.wikia.com/wiki/Gnar/Background

We don't implicate characters to species because there's always the possibility that they can be drawn as another species.

I'm pretty sure it's impossible to draw Gnar as a different species. Otherwise, it really wouldn't be Gnar anymore. Plus, the definition of a yordle seems to be quite open-ended. Besides, who the h draws tf art of LoL characters?
