In the Fourth Branch of the Mabinogi Dylan is born to Arianrhod in a miraculous narrative context connected to Math ap Mathonwy's court. When the newborn is baptised he plunges into the sea and 'immediately when he was in the sea, he took its nature'; he is recognised by Math and by his maternal kin (Arianrhod is daughter of Dôn), situating him within the household/divine family of Dôn. His birth and instant affinity with seawater mark him as a personified aspect of the sea rather than a mere human child.
The medieval account describes Dylan initially as a 'sturdy blonde boy' at birth but gives no sustained anthropomorphic detail. The decisive descriptive moment is his immersion in the sea at baptism after which he 'took its nature, and swam as well as the best fish that was therein.' Later modern summaries sometimes call him a sea-god or merman, but the primary narrative confines the depiction to a human infant who immediately manifests fully aquatic nature upon contact with seawater.
The primary attested ability is an innate and immediate aquatic adaptation: upon entering the sea Dylan 'took its nature' and swam as well as any fish. The narrative presents no catalogue of additional powers, cult, or ongoing intervention in human affairs; his status in modern summaries as a 'sea-god' is interpretive. His narrative is also bounded by mortality within the tale: he is struck and killed by his uncle Gofannon, showing that his marine nature does not render him invulnerable.

None recorded.
Elatha
Elatha is a figure in Irish medieval myth portrayed as a king of the Fomorians who also fathers several leading members of the Tuatha Dé Danann. He is depicted as a noble, luminous maritime prince associated with gold and light imagery and appears in narratives such as the Second Battle of Mag Tuired and genealogical accounts explaining the ancestry of figures like Bres, the Dagda, Ogma, and Lir.
Gofannon
Gofannon is a figure in Middle Welsh literature attested as a master metal-worker and named son of the goddess Dôn. He appears in Welsh tale-cycles in roles tied to smithcraft (for example sharpening a plough) and in a narrative incident in which he unknowingly kills his nephew Dylan Ail Don.
Dyaus
Dyaus (Dyáus; Dyauspitr/Dyauṣpitṛ́) is the Rigvedic daylight‑sky deity and archetypal 'Sky Father' whose union with the earth goddess Prithvi forms the prime parental pair in Vedic cosmology. He functions as a progenitor and sovereignty figure in hymns of the Rigveda and is cognate with the Proto‑Indo‑European daylight‑sky father (cf. Zeus, Jupiter).
Dybbuk
A malicious possessing spirit in Jewish mythology, believed to be the dislocated soul of a dead person. (Note: Power tier should be Lesser or Greater, not Primordial (the entity's power level seems too high for a dislocated soul). Origin story and Appearance sections are missing. Abilities should be more sp)
Dyesebel
Dyesebel is a fictional Filipino comic-book mermaid character created by Mars Ravelo and drawn by Elpidio Torres, widely adapted into films and television. In her stories she inhabits the marine realm, interacts with humans (notably a love interest named Fredo), and in some versions gains full human form via a bargain with a sea-witch.
Dyggvi
Dyggvi (Old Norse Dyggvi/Dyggve, glossed 'Useful, Effective') is presented in the Old Norse legendary-historical tradition as a Swedish king of the Yngling dynasty. He appears in genealogical and saga sources (Ynglingatal, Snorri Sturluson's Ynglinga saga, Historia Norwegiae, and the Íslendingabók succession list) and is said in later summary tradition to have died and become a concubine of Hel, the ruler of the dead.
Dying God (motif)
A comparative-mythology motif in which one or more deities die, are destroyed, or depart permanently from the world; used by scholars and popular writers to explain mythic themes of change, loss, fertility cycles, or cultural transition rather than denoting a single named being.
Dymas
Dymas (Ancient Greek: Δύμας) is a personal name borne by multiple distinct mortal figures in ancient Greek epic and mythic traditions rather than a single supernatural being. Bearers of the name appear in narratives connected to the Argonautica, the Theban cycle, Dorian genealogies, Trojan War material, and the Odyssey; no consistent divine or liminal attributes are ascribed to them in the cited sources.
Dynamene
Dynamene (Ancient Greek: Δυναμένη) is one of the Nereids in Greek mythology, a daughter of the sea-god Nereus and the Oceanid Doris. Her name is a participle meaning glossed as both “the bringer” and more precisely “she who can, the capable one,” and she is associated with the might of great ocean swells and with the ability to appear and disappear rapidly. She appears in Homer’s Iliad as one of the Nereids who comes to Thetis in her grief for Achilles.
Dyosa
Dyosa is a 2008 Philippine televised fantasy drama whose protagonist Josephine is portrayed in-series as the Takda (Chosen One), a predestined female figure of divine/supernatural origin who must restore balance between rival immortal factions. Within the show's internal cosmology, the Dyosa manifests elemental powers and transforms into three elemental forms to harness those powers.
Dyspontos
Dyspontos (also attested in a cataloguing entry as Dysponteus) appears only in very limited genealogical material within Greek mythic traditions connected to the royal house of Pisa in the Peloponnesus. The surviving attestations treat the name as a minor mythic figure recorded in lineage lists with variant parentage rather than as a fully developed narrative character.
Dywel fab Erbin
Dywel fab Erbin is a minor heroic figure of medieval Welsh literary tradition: a son of Erbin, brother to Geraint and Ermid, and named among King Arthur's knights at Celliwig. He is attested in early Welsh poetry (the Black Book of Carmarthen and the Stanzas of the Graves) and in the Arthurian tale Culhwch ac Olwen, where his death in battle and the location of his grave at Caewaw/Caeo are recorded.
