A man eater can refer to several things: an animal that has become accustomed to eating human flesh, a legendary plant that actively devours humans who stray too close, a human cannibal and a dangerous woman who has many lovers that she uses while being a dangerous threat to them.
"A man-eating temptress, she was once a woman that seduced countless men and committed unspeakable acts while alive. Now, even as a zombie, she maintains her appearance, continues to seduce men and literally devours them."
—Shin Megami Tensei: Liberation Dx2 compendium
Man Eater appears as both an event enemy demon and featured summon in celebration of the game's first anniversary alongside Bodyconian.
Undead demons appeared in droves one night. These demons were summoned by an Acolyte Dx2 whose goal was to revive Japan's "Bubble Economy" by turning the citizens of Tokyo into zombies. The Dx2 then hid herself deep in the Aura Gate, but was eventually forced to surrender by the protagonist and Megakin. Though the Dx2 who summoned them is now under custody, these demons are still running rampant in certain areas and need to be defeated.
Though the story depicted them as being seen all over Tokyo, Man Eaters can only be encountered standalone in the Aura Gate and drop 20 Juliana Fans upon defeat for the duration of the event. There is also a Gatekeeper form of said demon known as Empress Juliana.
