Ikelos leads the Ikelos Familia, possessing dark blue hair, brown skin, and an average-height frame, typically clad in black attire during his prime. His personality centers on finding personal amusement in chaos, elevating "fun" as his core moral guide while actively disavowing responsibility for his Familia's actions and denying affiliation. As Familia head, he oversaw a group initially focused on exploration that later shifted into black market operations, specializing in capturing and trafficking sentient monsters called Xenos. This involved ambushing and imprisoning Xenos like Wiene and her companions, leading to their torture and death by Familia members, including Dix Perdix. Ikelos directly confronted Bell Cranel regarding Wiene's whereabouts, demonstrating personal involvement in the hunt for escaped Xenos. His Familia utilized Knossos, an artificial labyrinth constructed by Dix Perdix under an ancestral curse; Ikelos supported its creation through illicit funding gained from Xenos trafficking. Following the Hestia Familia's intervention during the Xenos conflict—marked by the public rampage of an enraged Wiene and Dix Perdix's death—Ikelos faced permanent exile from Orario as punishment for his Familia's crimes, resulting in the Familia's dissolution. Trivia identifies "Ikelos" as an alternate name for Phobetor, the Greek god of nightmares.
