The Other was Thanos' personal servant. He provided Loki with the Chitauri army in an attempt to conquer the Earth and claim the Tesseract. In the wake of the failed Chitauri Invasion, the Other continued to serve Thanos and held frequent arguments with his new warrior, Ronan the Accuser until, in a fit of rage, Ronan killed the Other with his Cosmi-Rod by snapping his neck.
