Stargirl, Firestorm and Blue Beetle are forced to work together to defeat General Zod and his two Kryptonian henchmen after they inadvertently trap Superman in the Phantom Zone.
This episode provides examples of the following tropes:
- Cuteness Proximity: Stargirl gushes happily over a three-eyed alien kitten.
- Deus Exit Machina: Superman is trapped in the Phantom Zone for most of the episode, so the spotlight can shine on the younger heroes.
- How We Got Here: The episode begins with the three heroes fighting Zod and his cronies, and we learn how it came to be through flashbacks.
- Nice Job Breaking It, Hero: Stargirl takes the kitten into the room with the Phantom Zone portal, which then proceeds to make things go wrong, and the actions of all three young heroes lead to Zod and his cronies being released and Superman getting trapped in the Phantom Zone.
