In spring 2019, the Justice League returns for Justice League vs. The Fatal Five. Originally composed of supercriminals Tharok, Emerald Empress, Validus, Mano and the Persuader, the Fatal Five were first introduced in 1967 and are more commonly associated with the Legion of Super-Heroes. While they have appeared in animation before, both on Justice League Unlimited and on the Legion of Superheroes animated series, they’ve been largely dormant for a while (though Emerald Empress did play a key role in the recent Justice League vs. Suicide Squad comic book event). This is an original story, and there’s much we don’t know about it.
