Origin

Greek Dero: In classical Greek mythographic lists she appears as Δηρὼ, one of the fifty Nereids, daughter of the sea-god Nereus and the Oceanid Doris; the supplied source records the name and parentage but gives no individualized mythic narrative for her (Wikipedia: Dero (mythology)). Modern (Shaverian) dero: In Richard Sharpe Shaver's mid-20th-century writings and later commentary, 'dero' (often glossed in that corpus as "detrimental robots" or malicious subterranean beings) are described as inhabitants of abandoned caverns beneath the Earth's surface who use or operate ancient technologies to harm surface humans; this is a product of modern pulp/fringe myth-making rather than an inherited religious cosmology (fandom summary; MonsterTalk episode and related commentary).

Appearance

Greek Dero: The provided classical source lists her genealogically among the Nereids but does not supply a distinct physical description for Dero herself; she is therefore attested only as a named sea-nymph (Wikipedia: Dero (mythology)). Modern dero: Fringe and fandom summaries characterize deros variably as diminutive, sadistic humanoid or machine-using creatures, often mutated by environmental and technological radiation and associated with ancient machines; accounts differ across sources and no single consistent morphology is attested in the supplied material (aliens.fandom; Shaver-related reviews/discussions).

Abilities

Greek Dero: No individual abilities or deeds are recorded in the provided source beyond her membership among the Nereids (Wikipedia: Dero (mythology)). Modern dero: Shaver-derived sources and summaries portray deros as torturers of humans who clandestinely manipulate or operate neglected ancient technology from subterranean caverns to afflict or sabotage surface people; they are described as using machines and ancient tech rather than as possessing distinctly supernatural powers in the supplied material (aliens.fandom; MonsterTalk; related reviews).

Aba (disambiguation / name-form)

Aba is a polyvalent name-form attested across many unrelated contexts (place names, personal names, animal names, and brief mythological listings). The provided sources do not support a single, coherent supernatural entity called "Aba" and offer no descriptive or ritual material for such a being.

Abarbarea

Abarbarea is a name attested in classical Greek and Roman sources for freshwater nymphs (naiads). The name appears for at least two individual mythic figures — a naiad wife of Bucolion and a naiad counted among ancestors of the Tyrians — and Hesychius records plural forms that may indicate the name was also used as a class-name (Abarbareai / Abarbalaiai).

Abas

Abas (Ancient Greek: Ἄβας, gen.: Ἄβαντος) is not a single mythic being but a recurring personal name borne by multiple mortals and minor mythic figures in Greek epic and genealogical traditions — kings, founders, seers, warriors, attendants, a centaur, and a youth transformed by a goddess. The name is glossed in the sources as 'guileless' or 'good-hearted' and appears across Argive, Theban, Trojan, Euboean, and other local cycles.

Abderus

Abderus (Ancient Greek: Ἄβδηρος, romanized Ábdēros) is a mortal heroic figure in Greek myth closely associated with Heracles, remembered as the youth left in charge of the Mares of Diomedes who was killed by them. He functions as an eponymous local/divine-hero ancestor for the city of Abdera and received funerary commemoration and athletic agones at his tomb.

Abena Mansa

A name attested in a single contemporary Ghanaian blog anecdote as a 'mysterious being'; available sources do not establish Abena Mansa as a coherent, traditional supernatural figure or provide corroborating ethnographic detail.

Abin Sur is a fictional extraterrestrial Green Lantern from the planet Ungara in DC Comics. A former history professor turned Green Lantern of Space Sector 2814, he discovered and investigated a prophecy tied to the "Blackest Night," died wounded on Earth and chose Hal Jordan as his ring-successor, and was later reanimated as a Black Lantern in the Blackest Night storyline.
