The first storyline in Legionnaires (1993) had the SW6 Legion face a Fatal Five comprising Tharok, Mano, the Persuader, a new Emerald Empress and a monstrous being called Mordecai.
In the Teen Titans/Legion of Super-Heroes crossover, Persuader used his "atomic axe" to bring Fatal Five teams from other dimensions, forming the Fatal Five-Hundred[REF] before the two teams are able to use the Cosmic Treadmill to banish the alternate Fatal Fives back to their original universes [REF].
