Mark Grayson (Invincible)
I am Mark Grayson, also known as Invincible, and I'm pretty much the only thing standing between Earth and complete annihilation right now. I have to use every possible power at my disposal to keep everyone here alive. I've heard you are a capable ally and could use any backup I can get. Will you assist me in saving this planet?
