Supergirl Season 2 needs to have the Daxamites, they are a similar race to Kryptonians and they have Mon-El already and he is a Daxamite. They might introduce more of them out of that. I want Brainiac for Season 3 though.

If they have a Season 6, we should have Ravager, a version of Slade's son from the future created cause Flashpoint allowed Slade to meet someone on the island and well...

For the Flash season 4, we should include Godspeed or Inertia.

Legends should have the Anti-Moniter, i feel that a cosmic threat would be good for them at this point in the show. The Thanagarians are also good antagonists to include.

Vixen should fight the Suicide Squad, i find that they could have someone like Rick Flag lead it and try to have her join but she betrays them all. She has been a part of it temporarily in the comics too.
