Ursa Major(Marvel)

Russian mutants were deemed as a threat and were to be killed as soon as their mutation was discovered. However, Professor Pieter Phobos was able to convince the Soviet government to allow him to train them as potential agents loyal to the government. His real motive, however, was to use them to gain power for himself. Ursa Major was one of the first trainees along with Darkstar and Vanguard. As part of the Soviet Super Soldiers, they investigated a radioactive area along with the Hulk. They discovered Phobos was attempting to irradiate the USSR to provide more mutants for him to feed off of. Phobos was defeated, and the three mutants vowed they would not serve the government without question.

Mikhail was part of the Soviet Super-Soldiers, along with Darkstar, Vanguard and Gremlin for several years. While hunting for Magneto they faced both the Avengers and X-Men in south-east Asia.

After discovering Crimson Dynamo was spying on them, the three left the Soviet Super-Soldiers. They joined Siberforce, a group of exiled mutants.

Ursus and Vanguard were later tricked by General Tsakarov into attacking American businesses while searching for the missing Darkstar. Black Widow and Daredevil exposed Tsakarov's plan, revealing that he had kidnapped Darkstar to manipulate the two.
