A boastful Turanian champion who swore in drunkenness to slay Giv and Rostam. Driven by Afrasiab's mockery, he rode his black steed Shabrang, attacked Zourah (mistaking him for Rostam), and knocked him unconscious. Rostam intervened, impaled Alkus on his spear, lifted him, and smashed him to the ground, killing him.
