Episode 2: In About Six Hours, I Lose My Virginity to a Fish

While graduating, Mark defeats Doc Seismic and his Magmanites. Over the summer, tension grows between him and Debbie after she realizes he is only continuing his work as Invincible and working for Cecil to avoid Nolan's legacy. She confronts Cecil, during which she learns Donald is alive and later has a breakdown over continuous reminders of Nolan. After converting a vacant lot into a park, Eve argues with her father, believing he cannot accept that she can help with her powers. However, the park collapses due to being built on unstable ground, though no casualties were sustained. The stowaway Martian, who had taken the place of astronaut Rus Livingston, becomes inspired by original Guardian member Martian Man to become the superhero Shapesmith and join the current Guardians. After encountering and defeating Darkwing II, Mark is assigned by Cecil to appease the Atlanteans for original Guardian member Aquarus' death. Amidst a trial by combat, Mark battles a kaiju, but is injured by its roar. Nonetheless, he saves the Atlanteans from it against Cecil's orders. Angstrom travels to an alternate Earth where Mark was captured by the GDA to gain information on how to defeat his own.
