The Concept: Mark Grayson is just like everyone else his age, except that his father is the most powerful superhero on the planet. And now he's begun to inherit his father's powers. It all 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: Old doors close as new ones open. Mark Grayson, AKA Invincible, has reached the end of his high school years. Watch as our hero dons that goofy-looking cap and gown and hope some big super-villain doesn't crash his graduation ceremony. Then again, what are the chances of THAT happening?
