The first version of the Legion of Monsters was united by chance to investigate the appearance of a strange being called The Starseed.
[2] A new version of the Legion of Monsters was formed by Morbius the Living Vampire, the Werewolf by Night, and the Man-Thing.
They first appeared when the Moloids that work for the Man-Thing find the decapitated parts of the Punisher (who was sliced up by Wolverine's son Daken) and Morbius reassembles him as FrankenCastle.
[4] The Werewolf by Night and N'Kantu the Living Mummy are shown attempting to arrest the Dimensional Man for feeding on the life force of fellow monsters, before being joined by Morbius the living vampire and Manphibian, who ultimately work together to capture him.
When Morbius discovers that the monster is dead, Elsa is arrested and held in custody while he performs an autopsy on its body.
