Years later, in a subsequent campaign of terror by Thanos, Eros fought alongside Titan's handful of survivors. Eros joined the alien Captain Mar-Vell in battling Thanos's minions. Eros was held captive by Thanos, who revealed that he had killed their mother. Eros was freed from captivity and met Iron Man and Moondragon, and assisted Mar-Vell and the Earth hero-team called the Avengers in the first major defeat of Thanos. Eros later met Pip the Troll, and his relationship with Heater Delight was revealed. Eros was later held captive by ISAAC, but was eventually freed. No longer bound by duty on Titan, Eros left the war-torn moon, seeking out pleasure and recreation on humanoid-inhabited worlds.
