Hank. Really. Why though.
Before you go "I is indestructable I cannot be hit!!1!11!1!1 I killz u no try ez" because you probably will based off of your current choices, Imma say outright that you are NOT unkillable by any means whatsoever. Be prepared to do more than an endlessly long monolouge about how pwerful your OC is or some crap and use a hide block or delete Mike for your 'attack' or you will get humiliated in front of so many people. Just a fair warning, is all, If you AREN'T a salty nine-year-old then cool.
