The first Kha'zix fan art I find on Danbooru and its a Gender Bender version of Him...
And a naked one on the child post.

There prolly isn't any fanart of him on here because the artists on pixiv don't like him very much.

And because he's a stupid bug.

I love having Kha vs Rengar and now we have a genderswap for both

Mmm.. Kha'zix
