Virabhadra

In the canonical Purāṇic account of the Dakṣa yajña, Śatī (Sati) immolates herself after Dakṣa insults Śiva. Hearing of her death, Śiva produces Virabhadra as a violent emanation of his wrath—variously described as formed when Śiva plucks a lock of his matted hair and casts it down (hair-lock origin) or as an emanation from the god's bodily efflux in different tellings. Virabhadra is sent to the sacrifice to punish Dakṣa and the yajña participants; after the rampage Śiva recalls or pacifies him and restores order (sources: Wikipedia summary; Hare Kṛṣṇa retelling; Purāṇic summaries such as the Skanda Purāṇa; Padma Purāṇa note on variant origins).

Purāṇic summaries depict Virabhadra as a fearsome, martial figure: three‑eyed and bearing many arms, entwined with great serpents, and attended by vast chariots and mounts — descriptions in some sources give epithets such as 'bearing a thousand arms' and a chariot drawn by thousands of horses and multitudinous lions (Skanda Purāṇa as summarized). Devotional retellings describe his incandescent emergence when Śiva snatches a blazing strand of hair and laughs like a madman. Regional sculpture and bronze repoussée plaques portray him as a supreme warrior-hero in temple art in some South Indian contexts (museum/gallery description).

Virabhadra functions as a specialized warrior and agent of divine punishment: he lays waste to Dakṣa's sacrifice, slaughters devas and sacrificial participants, attacks principal gods (confronting Indra and other devas), and in variants assaults or plucks out the eyes of specific deities. He marshals heterogeneous troops — lists in the Purāṇic accounts include ganas, rakṣasas, yakṣas, piśācas (pishachas), hosts of bhūtas, yoginīs, and guhyakas — and can overwhelm the sacrificial order until checked. In some versions Viṣṇu intervenes with the Sudarśana cakra to oppose him (Skanda Purāṇa summary); other variants narrate complex interactions in which the cakra is swallowed and later returned or in which Virabhadra recognizes the unity of Viṣṇu and Śiva (different Purāṇic accounts). After his mission Śiva pacifies him and restores the victim (Dakṣa), showing Virabhadra's authority is derivative and recallable by Śiva (sources: Skanda Purāṇa summary; Wikipedia; Padma and Kurma Purāṇa reports as summarized).
