Godheads by Pantheon
Anasazi (Native American) - Manitou, though Tomazooma is shown in Thor I#300 (he didn't exist in real world mythology)
The Innua (Inuit/Eskimo) may or may not be a separate pantheon.
The Pueblo are referenced in Thor Annual#10, and might refer to Awonawilona.
Annunaki (Mesopotamian) - Anu
--Replaced by Enlil {Sumerian},
--by Marduk {Babylonian},
--by Ba'al-Hadad (Assyrian and Phoenician})
Asgardian (Norse) - Odin, Thor
Australian/Aboriginal Gods - mentioned in the OHotMU, but not seen.
Thuremlin per Ronald Byrd, Baiame per Eric J. Moreels.
Daevas (Hindu) - Vishnu (in trinity with Brahma and Shiva)
Vedic/Persian: Atar, Mitra/Mithras
Dievas (Russian) - Svarog
Heliopolitan (Egyptian) - Ammon Ra, Osiris, and Horus
--In Egyptian myth, Osiris was never more than god of the dead.
--Ammon Ra, however, was considered the Egyptian counterpart to Zeus (or Ouranos?).
Incan - Viracocha
Kahunas (Oceanic) - Tame
The Polynesian gods are specifically mentioned and would reference Tangaroa
Kalevalans (Finnish) - Ukko
Kami (Japanese Gods) - Izanagi, Takamimusubi, Amaterasu
--Religously, Izanagi was supplanted by the other two as the divine couple,
but all the myths revere Amaterasu as the true power and her husband as sort of a "figurehead"
Orishas/Loa (African/Voodoo) - Buluku; Ndriananahary, possibly also Nyambe, Lusa
The Yoruba are specifically mentioned, and would reference Olodumare
--My book on African spirits places a lot of importance as Nyambe as ruler, judge and Great Spirit.
--Lusa (Voodoo) is mentioned only as the sun-god who fathered the Great Twins of which Shango and Damballah are two of.
--In the MU, I would surmise that Buluku supersedes them both to keep dissension out of the Voodoo Gods and their relations, the Orishas {African Gods}
Mexican
With the subdivisions
Aztec Tezcatlipoca and perhaps Quetzalcoatl
Mayan Hunab-Ku and Itzamna
Mongolian/Siberian - Ulgen
Olympian (Graeco-Roman) - Zeus
Tuatha da Danaan (Celtic) - Dagda or Nuadhu
Xian (Chinese) - Shou-Hsing, Yu Huang
Judeo-Christian - God/Yahweh/Allah, Jesus Christ, Holy Spirit
--According to a former intern from Marvel, in What If I#32, the character seen in the bottom right panel of the gods and demons blocked from accessing Earth by Korvac was supposed to be Yahweh, though it looks more like Jesus.
