The Legion of Doom is 'one of the many super-villain teams that exist in the DC Universe. There are others, like the Injustice League, the Secret Society, the Injustice Society.

Similarly, the Marvel Universe has numerous super-villain teams like the Masters of Evil, the Sinister Six, the Frightful Four, and the Brotherhood of Mutants.

However, I think it's safe to say that the closest counterpart for the Legion of Doom is the Masters of Evil. The other mentioned teams are more focused on a franchise, the Sinister Six are Spider-Man villains, the Frightful Four are Fantastic Four Villains, and the Brotherhood of Mutants are X-Men villains. The Masters of Evil are Avengers villains, and because the Avengers are made up of heroes with their own franchise, it covers a wider variety of foes.
