No single traditional origin narrative is documented in the supplied materials. The Leak appears in Balinese and broader Indonesian popular belief as a personified form of dangerous sorcery and animistic fear around pregnancy and infants. Modern retellings and cinematic adaptations (for example the 1981 film Mystics in Bali / Leák, based on Putra Mada's novel Leák Ngakak) have kept the figure in contemporary circulation, but the provided sources note that detailed indigenous cosmological origins or a canonized origin myth are not present in the excerpts reviewed.
The supplied materials do not present a consistent, detailed indigenous description of physical morphology. Popular summaries and horror media depict Leak as a witch-like being and individual legendary Leyak are named in at least one secondary source (Cryptid Wiki), but the provided excerpts do not document specific, corroborated visual traits (for example, any fixed daytime human guise or nighttime flying-head motif cannot be asserted from these materials). Where modern accounts or films portray the entity, those are narrative depictions rather than ethnographic description.
Across the available popular summaries, Leak/Leyak is described as a malignant sorcerous being that attacks reproductive vulnerability: it is 'said to fly trying to find a pregnant woman in order to suck her baby's blood or a newborn child' and is characterized with cannibalistic behavior in some modern summaries (Cryptid Wiki). The figure functions in narratives as a feared supernatural phenomenon associated with black-magic-like danger; cinematic and literary treatments emphasize its harmful, frightening actions. The supplied materials distinguish between traditional belief and modern media portrayals but do not provide a full catalogue of powers beyond the predation on pregnant women and infants and the general label of a 'bad witch.'

Acintya
Acintya is an Indonesian Hindu theological-symbolic representation of the ineffable supreme divine principle. In Balinese and Javanese practice it functions as a way to make ultimate reality present in ritual and art—often aniconically as an empty throne (padmasana) or anthropomorphically as a naked, flame-surrounded figure—rather than as a narrative, intervening deity.
Aji Saka

Antaboga
Antaboga is a primordial serpent deity in Javanese and Sundanese traditional beliefs, later incorporated into Balinese Hinduism. Portrayed as an original creative being, Antaboga meditates and brings forth the world turtle Bedawang and other divine figures; its image appears widely in Javanese and Balinese ritual ornament and iconography.

Batara Guru
Batara Guru is a supreme divine figure in multiple Indonesian mythological traditions (Indonesian Hinduism, Batak, Bugis, Javanese). He functions variously as a guru-aspect of Shiva, a creator or world-recoverer in Batak narrative fragments, an ancestor and progenitor in Bugis and Batak genealogies, and a high deity of the kahyangan in Javanese cosmology.
Batara Kala
Batara Kala is a Javanese and Balinese underworld deity associated with death, time, and destruction; feared as an ogre-like devourer of the unlucky, he is also ritually propitiated to avert misfortune, especially for at-risk children.
Batara Sambu
Batara Sambu is a deity in Javanese Hinduized mythology described as the god or patron of teachers, the first-born son of the high god Batara Guru and queen Batari Uma. In wayang (Javanese shadow-play) tradition he is depicted as a ruler of clouds, ancestor of rakshasa (giants), and resident of the southern heavenly realm Kahyangan Swelagringging; his pasaran (Javanese calendar day) is Pa(h)ing and his palace is said to be made of copper.
Bawang Merah dan Bawang Putih
A widely told Malay/Indonesian folktale about two eponymous human stepsisters — Bawang Putih (the humble, patient sister) and Bawang Merah (the vain, cruel sister). The story uses small supernatural motifs (magic pumpkins, a talking fish, a gift-bearing old woman) set in rural liminal spaces to reward virtue and punish vice; it functions as a didactic children's tale rather than an account of a discrete spirit being.
Busang
Busang is not attested as a supernatural being in the supplied sources; rather it is a polyvalent proper name found as a toponym (places in Borneo), a lect name (Busang Kayan), a mining prospect label (Busang deposit in the Bre‑X scandal), and as a personal name. No mythological origin, appearance, powers, or ritual practices directed at a supernatural Busang are recorded in the provided material.
Calon Arang
Calon Arang is a witch figure in Javanese and Balinese folklore, traditionally portrayed as a master of black magic whose cemetery ceremony—including the sacrifice of a young girl to the goddess Durga—brings flood and an incurable plague to the village of Girah. In the tale a royal ritual specialist (Mpu Bharadah) and his disciple (Mpu Bahula) neutralize her by recovering her magic scroll and confronting her in ritual contest.
Chen Fu Zhen Ren
Chen Fu Zhen Ren (陳府真人; Hokkien: Tan Hu Cin Jin) is a deified ancestral/tutelary figure venerated in East Java, Bali, and Lombok. Centered on a historical/legendary migrant craftsman who became a local immortal, his cult is maintained in Chinese temples and by indigenous Kejawen practitioners and functions as a protective, communal ancestor patron.
