Kaikeyī

Kaikeyī is introduced in the Valmiki Rāmāyaṇa (Ayodhyā Kāṇḍa) as a princess of Kekeya who marries King Daśaratha of Kosala and becomes one of his three principal queens. A notable early episode relates that during a battle (narratively placed among cosmic struggles of devas and asuras or in martial campaigns), a bolt of Daśaratha's chariot wheel slipped; Kaikeyī inserted her thumb into the hole of the bolt to keep the chariot steady. Pleased, Daśaratha granted her two boons to be claimed later; those boons become the formal instrument by which she later demands Rama's fourteen-year exile and Bharata's coronation (sources: Valmiki Rāmāyaṇa — Ayodhyā Kāṇḍa; summarized in secondary sources such as Wikipedia).

The supplied sources do not supply a detailed physical portrait. Narrative descriptions emphasize status and comportment rather than bodily detail: she is depicted as the king's favourite queen, politically influential, temperamental and possessive in court matters, and capable in war (the chariot incident is presented as evidence of her presence and vigor). Modern summaries and encyclopedic entries foreground these character traits rather than specific physical features.

Kaikeyī is portrayed as an able counsellor and politically influential consort: among Daśaratha's wives she 'exerts the most influence' and is described as the king's favourite. She participates in wartime events (the chariot-bolt incident in which she steadies the wheel demonstrates practical courage and quick action). Her salient behavioral ability in the narrative is political agency — exercising prerogative through invocation of previously promised boons — and susceptibility to persuasion: her nurse Mantharā successfully convinces her to demand the boons that send Rama into exile. There is no indication in the provided sources of supernatural powers; her capacities are those of an influential mortal actor.
