The Concept: Mark Grayson is the son of the most powerful superhero on the planet. Recently he’s begun to inherit his father's powers, and in doing so, he has learned that everything he’s been told is a lie. His father wasn’t sent here to protect the planet, he was sent here to enslave it. The only thing that prevented him from succeeding was his own son. But he’s still out there, and nobody knows when he will strike again.

This Issue: Return to Midnight City! Cast in the shadow of perpetual darkness, Midnight City lost its sole protector to Omni-Man, Invincible’s father, as part of his plot to take over the world. Now many months have passed since the original Darkwing’s death, and there’s a new Darkwing in town. Invincible is curious to find out just who this guy is.
