Zuggtmoy is served by her lieutenant, Yibiyru, the Rancid Lady of Bitter Bile. She has been seen working with the demon lord Haagenti, the Lord of Alchemy, as well. She shares her layer of the Abyss with the demon lord Juiblex. Zuggtmoy is an ally of Iggwilv and Iuz, and has also been romantically linked to the latter. Recent publications, such as Fiendish Codex I: Hordes of the Abyss and Dragon, have Zuggtmoy retaining this appearance her original fungoid form has become a mere aspect. Instead of the almost comical puffball-mushroom look of T1-4, she was given a more fearsome appearance: resembling a blue-skinned demonic female with long sharp claws and whose lower body consists of strands of fungoid matter.

When the Temple of Elemental Evil computer game was released in 2003, Zuggtmoy was given an updated image makeover. Canonically, Zuggtmoy can also appear as a feeble old crone or a ravishingly beautiful human female. She could extrude pseudopods from her bloated body and squash opponents. A toadstool-shaped head with squashed and vague humanoid-like features resided atop her body.

As Lady of Fungi, Zuggtmoy as originally presented resembled a huge puffball fungus on top of four elephantine legs.
