Before the Doom Patrol can answer a call to save the world from The Candlemaker in the season finale, they must first battle long-forgotten imaginary friends.
As Niles and Cliff set out to find a missing Dorothy, Larry is tasked with handling Niles’ old research team when the ageless aeronauts return from space.
When the Dannyzens throw a massive party at Doom Manor to resuscitate Danny the Brick, Dorothy longs to join the festivities and experience life as a grown-up. As the party rages on, Rita asks Flex Mentallo to help unleash her full potential -- which has some dangerously racy consequences.
Niles, Rita, and Larry end up in the interdimensional clutches of Red Jack, an infamous villain who feeds on pain, while Cliff visits his daughter with Jane.
Cliff, Jane, and Rita pursue a time-altering doctor in their reluctant quest to help Niles and Dorothy. Meanwhile, Vic meets a military vet who challenges his beliefs.
The Doom Patrol (along with Niles & his daughter) are still mini-sized after their last adventure. Ultimately, Niles will have to sacrifice something precious to save the team.
