Ursa Major (comics) given the code name Ursa Major (though he is also known as 'Major Ursus'). The first mission of the Soviet Super-Soldiers was to investigate the contained radioactive area of Khystym known as the Forbidden Zone and to stop the Presence. There they encountered the Hulk, and discovered that their former teacher Professor Phobos was engaged in a project to radioactively contaminate all of the Soviet Union in order to foster the birth of more mutants whose powers he could eventually siphon. The Soviet Super-Soldiers, aided by the Hulk, thwarted Phobos's plan and brought him before the government to stand trial.
