In Rocky IV, what is the name of Apollo Creed's exhibition opponent?

In Rocky IV, Apollo Creed's exhibition opponent is Ivan Drago.

Apollo agrees to face Drago in a highly publicized exhibition match in Las Vegas. Drago is a new Soviet challenger presented as an extraordinary athlete, and the event is promoted as a showcase rather than a serious title contest.

Apollo treats the bout as a theatrical comeback, complete with a flamboyant entrance and James Brown's performance. Drago, however, fights with overwhelming force. Apollo refuses to stop, and Drago's punches cause fatal injuries.

Apollo's death changes the direction of the film. Rocky decides to face Drago himself, even though the fight is not sanctioned as a conventional championship bout. The exhibition therefore functions as the story's emotional turning point and links Apollo's legacy to Rocky's final confrontation.
