INVINCIBLE - Easter Eggs & Hidden Details

During Mark's fight with Angstrom Levy in the Season 2 finale, he is thrown through multiple dimensions. In one, he briefly encounters a hero named "Agent Spider" fighting a tentacled villain, a clear homage to Spider-Man and Doctor Octopus. Another portal shows a caped figure reminiscent of Batman. Mark also lands in a dimension filled with zombies, a direct reference to Robert Kirkman's other famous creation, "The Walking Dead".

Mark is often seen reading a comic book called "Seance Dog." In the original "Invincible" comics, his favorite comic was "Science Dog." The character of Science Dog is an homage that connects to Kirkman's other work; Carl from "The Walking Dead" TV show wore a shirt with the Science Dog logo.

In a flashback in the first episode, a young Mark Grayson wears a red t-shirt with "Canada" written on it. This is a nod to actress Sandra Oh, who voices his mother Debbie Grayson and is a Canadian native.

The original Guardians of the Globe are direct pastiches of DC's Justice League. The Immortal mirrors Superman, War Woman is Wonder Woman, Darkwing is Batman, Red Rush is The Flash, Aquarus is Aquaman, and Green Ghost is Green Lantern. This makes their shocking murder by the Superman-esque Omni-Man a powerful meta-commentary on the deconstruction of these iconic archetypes.
