Invincible Season 2 is now back up and running with new episodes, and the animated series is celebrating the release of Episode 6 with a new poster! Invincible Season 2 ended the first half of its run last Fall with several major intense events that set the stage for quite the terrible future for Mark. But the first episode of its big comeback this year has already proven that while Mark might need to deal with the Viltrumites in the future, they are far from the only threat that the Guardians of the Globe will have to face in the future to come.
