Reborn in Marvel, I am Iron Man's son?

Mark is reborn into the crisis-ridden Marvel universe as a newborn baby. And his identity? He's the illegitimate son of billionaire Tony Stark? Unfortunately, his womanizing father doesn't acknowledge him at all!

Today you ignore me, tomorrow I'll make you wish you were here!
