Kuśadhvaja is presented within the Ramayana's royal genealogies as a member of the Videha/Mithila kinship network. Sources identify him as the younger brother of Janaka, king of Mithila, and as husband of Chandrabhaga. In the episode recounting the war with Sudhanvan, Janaka kills Sudhanvan and crowns Kuśadhvaja as king of Samkasya; elsewhere he is associated with the area around Rajbiraj. Genealogical variants (noted in secondary discussion) attribute different filiation in other texts, but primary cited sources present him as Janaka's brother and as installed by Janaka in Samkasya.
The cited sources do not provide a physical description of Kuśadhvaja. He is characterized by social and familial roles: a king, younger brother of Janaka, husband, and father. Textual mentions emphasize his participation in courtly and ceremonial life—being present at the Sita–Rama wedding celebrations and being part of dynastic arrangements—rather than any bodily or visual details.
No supernatural powers or magical abilities are attributed to Kuśadhvaja in the provided sources. His activities are political and familial: he participates in royal ceremonies (he is summoned by Vashishta to the Sita–Rama wedding recitals), occupies kingship when Janaka crowns him king of Samkasya after Sudhanvan's defeat, and acts as a marital actor by fathering daughters (Mandavi and Shrutakirti) who marry into Rama's family. Sources do not ascribe extraordinary or otherworldly capacities to him.

Janaka
Janaka is a legendary and dynastic king of Videha (capital Mithila) who functions in Indic sources as an exemplar of ideal kingship and spiritual realization—a ruler who combines political authority, patronage of Vedic learning, and non-attachment. The name is used both as a regnal title for Videha's kings and as the personal/regnal name of the famous monarch who is the adoptive father of Sītā in the Rāmāyaṇa.

Mandavi
Mandavi (Sanskrit: Māṇḍavī) is a princess of Videha (Mithila) in the Ramayana tradition, wife of Bharata, and is regarded in some retellings as an incarnation of the shankha (conch shell) of goddess Lakshmi. She functions as an exemplary pativrata (dutiful wife) noted for sacrifice and perseverance and figures in narratives that link Mithila and Ayodhya through dynastic marriage.

Rāma
Rāma is a major divine-hero in Hindu tradition, worshipped as the seventh avatar of Viṣṇu and the central protagonist of the Ramayana. He is portrayed both as the ideal man (maryāda puruṣottama) and, in Rama-centric sects, as the Supreme Being; his life-story (birth in Ayodhyā, 14-year exile, Sītā's abduction, and the defeat of Rāvaṇa) functions as a primary exemplar of dharma.
