Taunt: B*&$h! I am the hype!
That's it, everyone dies!
Joke: Is that me? Is that me stronger than me?!? I'll F*&king kill me! Of course it's not nice I'm F&^%ing EVIL!!!

Movement, or attacking a minion/champion: Mine, mine, mine, Mine MINE!
Is the kit overpowered, yes, but I could have done worse. I considered giving him AD scalings as well. o.0
