Teen Titans Go! & DC Super Hero Girls: Mayhem in the Multiverse (2022) Timeline Explained – Every Event in Order

Lex Luthor discovers an ancient Kryptonian Amulet that grants him the power to rescue villains from imprisonment. Using this artifact, he assembles the Legion of Doom with the goal of capturing every Earth hero and imprisoning them in the Phantom Zone. However, the heroes later discover that Luthor is actually being controlled by Cythonna, the Kryptonian Goddess of Darkness, who is using him as a vessel to execute her own plan.

Foreshadowing: Earlier, the Amulet is shown pulsing with mysterious energy when Beast Boy discovers a crystal at the Titans' base.

Cythonna is the Kryptonian Goddess of Darkness, Plague, and Suffering. She was sealed away inside the Amulet by Rao (the Kryptonian sun god) and banished into space centuries ago. The Amulet kept her dormant until Lex Luthor discovers it. Cythonna uses Luthor as a puppet to execute her true plan: capturing heroes so she can feed on the souls of the wicked and claim the universe for herself. The heroes realize mid-story that Luthor is being controlled.

Foreshadowing: The Kryptonian runes discovered in Metropolis Park bear Cythonna's name, hinting at her identity before the reveal.

After Cythonna traps Supergirl and other heroes in the Phantom Zone, the remaining heroes pursue her through Zatanna's magic. This causes a dimensional breach that strands them in the Titans' dimension. The Titans help them repair Bumblebee's computer, which enables travel between universes so they can continue their mission.

Foreshadowing: Control Freak's earlier announcement about a forced superhero crossover sets up the multiverse collision.

When the Amulet shatters and Cythonna grows stronger, the Legion of Doom executes their trap. Superman is specifically imprisoned in a Kryptonite box because Kryptonite is the only substance that can neutralize his powers. This ensures he cannot escape or fight back while the villains carry out their plan.

Foreshadowing: Jor-El's warning hologram explicitly describes Cythonna's strategy of capturing powerful heroes.

After the Legion captures the League and their plan accelerates, Harley Quinn decides to leave the Legion. She helps Wonder Woman escape from the Phantom Zone trap and withdraws from the villainous plan. Her shift in loyalty appears to be triggered by the heroes' crisis and her growing reluctance to participate in the scheme once she sees how far Cythonna's plan has gone.

Foreshadowing: Harley's early presence in the Legion shows her initial involvement before her change of heart.

The heroes first trap Cythonna inside a crystal in the Zone after Supergirl and her allies subdue the Legion. Later, when Cythonna possesses Control Freak to retrieve the crystal in the Titans' universe, Raven uses a counterspell to banish Cythonna to the Super Friends' dimension. The heroes decide not to send the crystal back, effectively trapping her permanently outside their universe.

Foreshadowing: Zatanna's magic was previously used to banish Cythonna from their universe, setting up the magical resolution.

The Amulet is an ancient Kryptonian artifact that contains sealed inside it Cythonna, the Goddess of Darkness. When Lex Luthor finds it, the dormant power awakens and he uses it to recruit villains into the Legion of Doom. The Amulet also serves as a containment vessel for Cythonna - when it shatters during the story, she breaks free and becomes more powerful, allowing her to pursue her own plans directly.

Foreshadowing: The crystal Beast Boy discovers at the Titans' base pulses with energy similar to the Amulet's power.

The Titans initially become involved when the Super Hero Girls arrive stranded in their dimension after pursuing Cythonna. The Titans help them repair Bumblebee's computer to enable cross-universe travel. When Cythonna later invades their own universe through Control Freak to retrieve the crystal, the Titans directly join the fight alongside the Super Hero Girls to stop her.

Foreshadowing: Control Freak's meta-announcement about a forced crossover at the beginning hints at the eventual team-up.

During the visit to the Fortress of Solitude, Batgirl secretly steals crucial crystals and data. While Wonder Woman halts the fight and trusts Superman with other crystals, Batgirl's theft suggests she believes the League cannot be trusted with these powerful artifacts or wants to ensure they don't fall into the wrong hands if the mission fails.

Foreshadowing: The team's fractured trust after the League's capture validates Batgirl's precautionary actions.

Jor-El's hologram message appears to outline Cythonna's plan to feed on the souls of the wicked using a Kryptonian vessel to claim the universe. This message helps the heroes deduce that Luthor is being controlled by Cythonna and alerts them to the true scope of the threat, though they struggle to warn the rest of the League in time.

Foreshadowing: The Kryptonian runes found earlier contain Cythonna's name, connecting to the Kryptonian origins revealed in Jor-El's message.
