Major Story Arcs
The Goon Volume Three
Dug up by Houstus Grave & brought back into the mortal world by the Zombie Priest; the Mother Corpse helped bring forth an entire army of feral offspring to aid the Zombie Priest in his fight against the Goon. A spell was then cast on her by The Arab that fused several off her offspring with the spirit of Labrazio to use him in the fight against Goon. After the defeat of Labrazio and the Zombie Priest the spell on the Mother Corpse was removed and she was finally allowed to rest.
Powers & Abilities
It is unknown if she was granted her abilities on resurrection or if it was due to additional spells cast by the Zombie priest & The Arab, but the Mother Corpse had the ability to produce a massive amount of feral, undead offspring that could shape-shift & combine themselves into new and hideous forms. Despite missing the lower half of her torso she was still able to survive, displaying some level of invulnerability/durability.
