When someone very close to Invincible is hurt " the gloves come off! Is Mark Grayson's murderous Viltrumite heritage finally coming to the forefront? Find out in this special stand-alone issue that answers the question once and for all: can Invincible be driven to MURDER?

Collects issues #1-4! Mark Grayson is just like most everyone else his age. He's a senior at a normal American high School. He has a crappy part time job after school and on weekends. He likes girls quite a bit... but doesn't quite understand them. He enjoys hanging out with his friends, and sleeping late on Saturdays... at least until the good cartoons come on. The only difference between Mark and everyone else is that his father is the most powerful superhero on the planet, and as of late, he seems to be inheriting his father's powers. Which sounds okay at first, but how do you follow in your father's footsteps when you know you will never live up to his standards? THIS ISSUE: Get in on the ground floor, because it all starts here! Strange things begin to happen to Mark Grayson as he begins to develop superpowers. Luckily, his dad is around to show him the ropes, at least he WOULD be if he weren't so busy saving the world all the time. Mark is forced to go out on his own, and try and figure out how all this superheroing business works. The results are a monumental disaster, at least until he gets the hang of it. Watch Mark thwart thieving super-villains, alien invasions and all sorts of craziness.

THE VILTRUMITE WAR CONTINUES! THE FINAL STAND! It's all come to this: The fate of all life on Earth is at stake. If Invincible loses... Wait, Invincible can't lose... can he?
