As she grows closer to Sebastian, Rachel makes an unsettling discovery that leads the Titans to The Organization's Asylum, from season one. The team finds an entrance to the asylum basement, and discovers several recordings, detailing Bennett's life as a member of the cult. They learn that in 1998, Bennett gave birth to a baby boy who was rejected. Bennett summons an army of undead zombies to attack the Titans, including their former foe Deathstroke, but they manage to escape, though Conner is wounded by Zombie Deathstroke in the process of escaping.
"Super Super Mart" contains the following tropes:
- Back from the Dead: Mother Mayhem brings back the body of Deathstroke, the Big bad of Season two, to fight the team as an undead puppet she controls.
- Fake Shemp: It's blatantly obvious that Esai Morales did not reprise as Zombie Deathstroke.
- Long-Lost Relative: Sebastian is the son of Mother Mayhem and Trigun this makes him the half-brother of Rachel.
- Marionette Master: Mother Mayhem is literally able to puppet Deathstroke's corpse remotely to fight the whole team. Similarly, Jinx is able to stop all of the zombie temporarily with the spell and hold them immobile while the team regroups.
- Off with His Head!: Jinx says this is the only way to kill the zombies. Doesn't work on Deathstroke.
- Power Incontinence: May in her earlier life doesn't seem to be able to control her powers as evidenced by when they flare up at work and she involuntarily forces a man to jump to his death. She later tells Adamson that she has been fired from several jobs recently, implied to be because of her powers.
- Weak to Magic: Jinx tells Connor that Superman is susceptible to magic, calling it a "phobia" and saying Connor is susceptible also. Later Mother Mayhem is able to use magic to stab Connor and hurt him, despite his invulnerability.
- Zerg Rush: The Titans such as Connor and Dick are strong but the zombies overwhelm them temporarily with their sheer numbers.
