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. 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.

Mikhail is one of the mutants who retained his powers after M-Day. He later returned to Russia, joining the new Winter Guard, investing the death of Abomination, repulsing the efforts of the Lady Liberators when they attempted to interfere in international business, and then facing the Remont 6 and mentoring new Darkstar, Sasha Roerich.

When he and the Winter Guard tried to capture the Intelligencia, the group used the Zero Cannon on them, sending the team to space and apparently killing them.

Powers and AbilitiesEdit

Powers

Transformation: Ursa Major is capable of transforming into a humanoid brown bear. This process grants him an additional 14 inches in height and 700 lbs to his frame. While in his bear form, he retains his full level of intelligence, personality, and ability to speak.

Superhuman Strength: While transformed, Ursa Major possesses superhuman strength much greater than an actual brown bear of similar size. At his peak, his strength is sufficient to lift about 15 tons.

Peak Human Speed: Like an actual brown bear, Ursa Major is capable of running at speeds of up to 35 miles per hour.

Superhuman Stamina: Ursa Major's musculature produces much less fatigue toxins during physical activity than the musculature of an ordinary human. He can exert himself at peak capacity for several hours before fatigue begins to impair him.

Peak Human Agility: Despite his great size and bulk in his transformed state, Ursa Major's agility and bodily coordination are equal to that of an Olympic level athlete.

Peak Human Reflexes: Ursa Major's natural reaction time, much like a real brown bears, is equal to that of an Olympic level athlete.

Superhuman Durability: The tissues of Ursa Major's body are harder and more resistant to certain injuries than those of a normal human. Ursa Major is particularly resistant to great impacts and blunt trauma force. While not invulnerable, he can withstand impacts, such as falling from several stories or being repeatedly struck with superhuman force, that would severely injure or kill a normal human with little to no injury.

Superhumanly Acute Sense Of Smell: Like a real brown bear, Ursa Major possesses a highly developed sense of smell. He is capable of tracking a target by scent with an impressive degree of success, even if the scent has been eroded over time by natural factors such as weather conditions.
