Episode 11: Terrors
Takes place on September 14 - 16
The League captures the Terror Twins, a Brother–Sister Team of supervillains. However, it is a disguised Superboy and Miss Martian who get sent to prison in their stead.
It turns out that Batman suspects that the various ice-powered villains (all captured in the first episode) are getting themselves arrested on purpose, to be transported to Belle Reve, a prison for supervillains, and he wants to know why. While the two young heroes infiltrate it, Aqualad and Red Tornado watch from an invisible airship nearby. The prison is under the control of Amanda Waller, the warden, and the psychologist Dr. Hugo Strange.
In the prison, everyone wears collars that inhibit their powers and can be used to shock them into submission. This includes the heroes; only Miss Martian's telepathy and Superboy's super senses still work.
Superboy 'befriends' Icicle Jr., a young villain whose father, the original Icicle, is the "prison boss". It turns out the villains were waiting to use their combined supercold powers to make the prison walls brittle enough to smash through. They manage to free all the prisoners. However, Superboy tricks Icicle Jr. into helping him reactivate the prisoners' collars.
In the end, Waller is fired and replaced with Strange - which was Icicle Sr.'s goal all along; they both work for The Light. Out of all the criminals, Edward Nigma, aka The Riddler, somehow managed to escape.
Notes:
- Hugo Strange is an old Batman villain.
- Second episode in a row where Kid Flash, Artemis and Robin do not appear, and Robin's third overall. If we count the episodes prior to her formal introduction, this is Artemis' seventh non-appearance; otherwise, it's her and Wally's second.
- Superboy and Miss Martian kiss for the first time.
- The prison, Waller, and the concept of the inhibitor collars are all based on the DC Comics series Suicide Squad.
