“ I am strong... Extra-ordinarily so much more than you guys! Therefore, I am perfectly capable of kicking those titan scumbags' collective ass including on my own if I have to. Are you all such a bunch incompetents? You gutless spineless cowards. You just stay there and watch in helpless envy. Yeah, you do that. If it is (impossible), then I'll die... It's just that simple. But if I win, I get to live. You don't stand a single chance to win unless you fight. ”
