Joseph Morgan and Frank Potente are the latest additions to Season 4 of DC Superhero show, Titans. Joining them in the HBO Max show is Doctors-fame Lisa Ambalavanar.

Both are playing supervillains in the series, and while Morgan is set to play Sebastian Blood/Brother Blood, Potente will play May Bennett/Mother Mayhem, respectively. 

Brother Blood is an introvert with strong intelligence and a hidden darker nature, and Mother Mayhem is described as a natural leader who always carries the threat of violence with her, a predator in human form with an unfettered belief in her mission in the world.

Lisa returns as Jinx, a quick-witted criminal loner and a master of dark magic with a joy for manipulating others and creating chaos while doing it.

With Greg Walker as showrunner, Titans is backed by Weed Road Pictures and Berlanti Productions, in association with Warner Bros Television.
