Doom Patrol was easily the weirdest and most interesting show to come out of the short happy life of the DC Universe streaming service, and the show ended up getting a third season when it made the interdimensional jump to HBO Max. Now, Doom Patrol is gearing up for production on Season 3 and has added a bunch of cast members for two groups that promise to be more than weird enough for the Doom Patrol.

Doom Patrol Season 3 will introduce the Sisterhood of Dada and the Dead Boy Detective Agency. The Sisterhood of Dada is obsessed with all things absurd and bizarre, sort of an opposite of the show's recurring villain, the Bureau of Normalcy, which weeks to contain and weaponize all things abnormal. Even so, the Sisterhood is historically regarded as being evil, even if the group itself doesn't see things in such absolutes. The Dead Boy Detective Agency, meanwhile, is a three-person team consisting of a medium and two boy ghosts who read every book in their school's library to learn how to become detectives.

Make sure to read every character description (unless you're spoiler averse), because each one is wilder than the last. The cast members that make up the Sisterhood of Dada are all season regulars, meaning we'll be seeing them throughout the show's third season.
