During his long lifetime, Ikaris also attempts to be a fair and just leader of the Eternals, but has abandoned Eternal traditions to take an active and public role in protecting the human race. He has even adopted a unique human identity by becoming a professional wrestler with the Unlimited Class Wrestling Federation as "Iceberg" Ike Harris. Ikaris and fellow Eternal Thena have had a strong dislike for each other for a long time, and find themselves coming to conflict when she is appointed as Prime Eternal. Questioning her worth as Prime Eternal, Ikaris faces her in the Hall of Eternal Judgment and defeats her, becoming the new Prime Eternal. Ikaris then battled Ghaur alongside the Eternals, Thor, and the West Coast Avengers. He also buried Margo Damian when she was killed by a Deviant experiment.
