Invincible - Here Goes Nothing

With his father in the hospital, apparently another victim of whoever killed the Guardians, the second episode of Invincible focuses on expanding the world and giving Mark (Steven Yeun) his first real action as a hero working alongside Teen Team to fight off an alien invasion. Don't worry, he'll get better at the whole super-hero thing. Several of the teen heroes will get larger roles as the series continues, including Atom Eve (Gillian Jacobs) who Mark discovers goes to his high school and becomes the first person he can talk to about the unusual path his life has suddenly taken. The episode is also notable for the first appearance of Allen the Alien (Seth Rogen) testing the planet to see if its heroes are up to snuff. As with the Flaxans, we'll see Allen again before the end of the season.
