Hiranyaksha had an elder brother named Hiranyakashipu, who similarly achieved a boon of invulnerability and conquered the three worlds, seeking vengeance for his brother's death. He tried to persecute and abuse his son Prahlada for being a faithful devotee of Vishnu. While Hiranyaksha was slain by Varaha (the boar avatar of Vishnu), Hiranyakashipu was killed by Narasimha, the fourth avatar of Vishnu. Their sister was Holika, who tried to kill her nephew by attempting to immolate him, but got burnt herself and killed.
