Lavanasura

Lavanasura is described as the son of the asura king Madhu and his wife Kumbhini. Madhu, who is portrayed as kind to brahmanas and friendly with devas and who had been granted a trident by Shiva, established his realm called Madhupuri. Lavana, however, inherited the martial legacy and the trident, developing characteristics opposite to his father: violent, predatory, and hostile to sages and kings. In the narrative he continues to harass sacrificial rites and local rulers during the reign of Rama, prompting the sages to seek royal intervention. The epic account culminates with Shatrughna, acting on Rama's counsel and with Rama's weapon, confronting and killing Lavana and restoring proper kingship at Madhupuri.

Primary sources summarized in the provided material do not furnish a detailed physical description (coloration, number of limbs, monstrous features). Narratives emphasize his great physical strength and combat behavior — for example uprooting and hurling trees in battle — and his habitual wielding of a trident (trishula) inherited from his father Madhu. Childhood cruelty is narrated (he beat, killed, and ate playmates), conveying a ferocious and dangerous corporeal presence rather than specific morphological traits.

Lavanasura is presented as a violently aggressive and destructive being who routinely attacks sacrifices and terrifies sages and people within his domain. He defeated multiple kings and used the trident inherited from Madhu to devastating effect (the weapon is treated in the story as effectively invincible or devastating while he held it). In combat he demonstrates superhuman strength — uprooting and throwing trees — and is characterized as a predatory hunter who habitually went out hunting for food. His possession of the trident and his pattern of disrupting ritual and political order mark him as a potent local threat within the epic cosmology.
