Genetically engineered with cockroach DNA, the extradimensional Kree Noh-Varr joined the 18th Kree Diplomatic Gestalt, a team of intergalactic peacekeepers who became lost in transdimensional space when they encountered 3 astro-gods siphoning energy to explore Hypospace (the Omniverse). During the encounter, space-time collapsed, and the group was forced to escape through Macrospace. They careened through the Microverse and explored a multitude of realities while trapped there, until the alien-obsessed Midas caught their S.O.S., trapped them on Earth-616, and destroyed their ship. The sole survivor, Noh-Varr escaped Midas and destroyed his building before retreating to the New York subway system, which he made his temporary home. The enraged Noh-Varr, who had lost his lover Merree in the crash, took his aggression out on New York City, battling S.H.I.E.L.D. and their new experimental superteam, the Bannermen, a team of genetically enhanced superhumans pumped with gamma radiation and laced with Adamantium, whom he easily defeated. After destroying the living, planet-conquering corporation Hexus by sending their trade secrets to other companies and making them obsolete, Noh-Varr met Midas' head assassin and daughter, Exterminatrix.
Battling the Exterminatrix and Midas throughout New York City, Noh-Varr lost. Midas was about to kill him when Exterminatrix rescued Noh-Varr and escaped with him. Noh-Varr and Exterminatrix bonded over their mutual hatred for her father before Midas' agents, including one of the Dark Dimension's Mindless Ones, discovered them, forcing them to flee once more. Encountering the Cosmic Man, a renamed and newly empowered Midas, Noh-Varr immediately shot him in the head, which barely affected him. As Cosmic Man toyed with Noh-Varr, Exterminatrix used the decapitated Mindless One's head to shunt her father into the Dark Dimension, where he was attacked and seemingly killed by a large horde of the Mindless Ones. While Exterminatrix mourned her father, S.H.I.E.L.D. captured Noh-Varr and dragged him away to the Cube, a giant prison for super-villains, which Noh-Varr promised would be the capital of the new Kree empire within five months.
