Sisilkhan is the younger son of the raven-creator Kutkh and Miti and the standing villain of the Itelmen tale cycle: envious, lazy and boastful, he covets his elder brother Ememkut's game, brides and good fortune, sends his sister Sirim to spy and slander, and is regularly shamed or destroyed by his own devices. Meletinskii notes that in some tellings the scheming pair function instead as cousins of the elder children, and records the variant name Chichikan. The figure corresponds functionally to the envious-cousin antagonists (Illa, Kilu) of the neighbouring Koryak Raven cycle.
