In Gnosticism, Yaldabaoth is the Demiurge (a flawed, ignorant creator god) who rules over and imprisons souls within the material realm.

• The False God: Born of the Aeon Sophia without her divine consort, Yaldabaoth is blind to the higher spiritual universe (the Pleroma) and arrogantly proclaims, "I am God and there is no other".

• The Material Prison: He fashions the physical universe, planets, and lower heavens as a copy of the divine realm, trapping human beings—who carry a divine spark of light—inside physical bodies.

• The Archons: He rules alongside a council of lower cosmic rulers or demons called archons, who act as wardens and gatekeepers to prevent human souls from awakening or ascending back to the true God.

• Symbolic Form: He is frequently described or depicted in Gnostic texts (such as those from Sethian and Ophite traditions) as a monstrous, lion-faced serpent or dragon.
