Fan CastingTeen Titans Season One (Arrowverse)

This season runs alongside season 7 of Arrow, season 5 of The Flash, season 4 of Supergirl, Season 4 of Legends of Tomorrow, and Season 2 of Black Lightning. The episode opens with Roy, Thea, and Nyssa searching for the remaining Lazarus Pits. Eventually, they find one, but when they do, they're taken down by an assassin. They can't see who it is. When they wake up, Slade Wilson is standing over them in his Deathstroke suit. He explains that he needs them to kill someone for him, and shows them a picture of a man neither Roy or Thea have seen before, but Nyssa recognises him. She tells them that it's Trigon the Demon in his human form. Roy at first responds with "I don't kill", but when Slade threatens them, they agree to help him. Later, when Roy and Thea are looking for Trigon with a tracker bomb on each of them, placed there by Slade, they decide they need to get help. Roy goes to see Wally West, who is meditating, and Thea goes to Earth-38 to see Supergirl. Supergirl explains the she can't join them as she has duties on her own earth, but then reveals that she actually has another cousin as well as Superman. His name is Kon-El, and he goes by Supergirl. Meanwhile, Wally is complaining that whenever he meditates people come to recruit him, while Roy is trying to convince him to join their team. He eventually manages. So Arsenal, Speedy, Kid Flash and Superboy set out, then the episode goes on from there.
