Necropossums are an original species created for the Floraverse canon. They have the ability to resurrect themselves and attach various body parts. Necropossums who have not gone through a death process yet can reproduce.

Necropossums exist in various stages of decomposition. They are typically undead, or zombies. However, they are still intelligent. They also possess the ability to raise the dead under their control, as well as to manipulate anthropomorphic objects such as dolls, puppets, and mannequins.
