Mikhail Ursus

Mikhail Ursus is a Russian mutant born with the ability to transform at will into a massive humanoid brown bear while retaining full human intelligence and speech. He joined the Soviet Super-Soldiers as Ursa Major, serving as one of the USSR's government-sanctioned superhuman defenders.

Mikhail Ursus is one of Marvel's most intriguing Cold War-era creations, bursting onto the scene in The Incredible Hulk #250 in 1980 — a landmark Bronze Age issue brought to life by the legendary team of Bill Mantlo and Sal Buscema. With team affiliations spanning the Soviet Super Soldiers, the Fantastic Four, Alpha Flight, and the Avengers, this character has moved through Marvel's universe with a remarkable breadth of allegiance, sharing pages over the decades with heavy-hitters like Wolverine, Darkstar, Vanguard, and Ursa Major. Across 54 appearances stretching all the way to 2026 — touching titles as varied as Rom, The Incredible Hulk, and Captain America — Mikhail Ursus has proven quietly enduring, with two collector-significant key issues to his name; for fans who love digging into the rich geopolitical texture of Bronze Age Marvel, he's absolutely worth tracking down.
