User blog comment:TaC0CaT/Kha'Zix, the new shapeshifter assassin from the Void?/@comment-5194571-20120918181159

The whole "evolve and adapt" thing makes me think of Viktor. Rengar has a unique item, so it wouldn't be surprising to see another. It sounds like you can choose to upgrade his QWE depending on how the game is going, so I'd like to see an assasin version of Viktor.

Or he could be like Karma. R works like Mantra and the upgraded versions are the R enhanced ones and are meant for different situations.

Both seem to fit the idea of "evolve and adapt" and personally, I'd be happy to see either.
