- Lucifer (who is in basically every mainstream occult current and more)
- Lilith (same deal as Lucifer, except she’s not always as recognized sadly. However she’s a very powerful goddess in the sex current.)
- Satan (Satanism, sometimes Luciferisnism, Demonolatry, even in traditional Witchcraft as the devil or equivalent entity.)
- Set (Satanism, Setianism, Egyptian, Draconian, Demonolatry)
- Sekhmet (Satanism, Egyptian, Demonolatry, Draconian)
- Leviathan (Draconian, Demonolatry, Satanism)
- Behemoth (same as Leviathan.)
- Basically all demons have a place in at least Demonolatry and Satanism
- Samael (Samael is an angel as well as an avatar or name of Satan and he can be both dark and light. This also applies to Lucifer strangely.)
- Tiamat (she is one of the main gods of the Draconian current but she is also a Babylonian creation deity and has a place in the Cthulhu current).
- Bast/Bastet (Egyptian, Satanism and Cthulhu.)
- Shiva (Hindu currents like Tantra, Satanism, Demonolatry…)
- Shakti (see Shiva)
Feel free to add to what’s already here. This is only what I’ve come up with from the top of my head.
