• Hindu / Vedic — The Nagas: Half-human, half-serpent beings who live in underground realms (Patala, the underworld). They're classic reptilian—snake lower bodies, hoods, shape-shifters. Directly from under the earth, interacting with surface humans.


• Egyptian — Apep (Apophis): Massive chaos serpent who dwells in the Duat (underworld), slithering through it nightly to attack Ra. Pure reptilian—giant snake/dragon form - From under the earth.


• Babylonian / Mesopotamian — Tiamat: Primordial chaos dragon/goddess, often reptilian (multi-headed, scaly, serpentine). Her body forms the earth after defeat, but she's tied to watery depths/primordial abyss (underworld precursor). Close, but more "from the deep" than strictly underground caves.


• Norse — Nidhogg: A massive dragon/serpent gnawing at Yggdrasil's roots in Niflheim/Hel (the underworld). Described as serpent-like, malicious, dwelling below. Reptilian vibe as a dragon-serpent.


• Native American (Hopi) — The Sheti or "Snake-Brothers": A race of reptilian beings living underground, mentioned in Hopi lore as helpers or hidden folk. Some traditions call them reptilian humanoids. Emerging from below.

• According to Job, the Rephaim are beings that have come from below Hell:

Job 26:5-9 WEB "(Rephaim)The departed spirits tremble, those beneath the waters and all that live in them. (6) Sheol is naked before God, and destruction) Abaddon has no covering. (7) He stretches out the north over empty space, and hangs the earth on nothing. (8) He binds up the waters in his thick clouds, and the cloud is not burst under them. (9) He encloses the face of his throne, and spreads his cloud on it.

In Isaiah the Rephaim have taken over earth:

Isaiah 14:9 WEB Sheol from beneath has moved for you to meet you at your coming. It stirs up the (Rephaim) departed spirits for you, even all the rulers of the earth. It has raised up from their thrones all the kings of the nations.
