In Rocky IV, what is the name of the Soviet boxer Rocky faces?

In Rocky IV, the Soviet boxer Rocky faces is Ivan Drago.

Drago is introduced as a physically imposing amateur champion backed by Soviet officials and advanced training technology. He challenges Apollo Creed in an exhibition match in Las Vegas, where a fatal series of punches kills Apollo in the ring.

Rocky accepts responsibility for facing Drago in a Christmas Day bout held in Moscow. The fight is framed as a personal contest, but the film also gives it Cold War symbolism, contrasting American and Soviet institutions and public reactions.

Dolph Lundgren played Drago, while Brigitte Nielsen played his wife, Ludmilla. Drago later returns in Creed II, where his son Viktor faces Adonis Creed. This makes Ivan one of the few Rocky antagonists whose family continues the boxing rivalry into a later generation.
