The Legion of Doom is a faction, comprised of various different enemies to the members of the Justice League.
Following the creation of the Justice League and defeat of Steppenwolf, Lex Luthor had escaped from Arkham Asylum and contacted Deathstroke. Slade met with Luthor on his yacht, where he proposed the creation of a league to combat that of the Justice League.

- It is unknown if the team will be called Legion of Doom or Injustice League, since Luthor said it would be a league.
