It was as epic as it was heartbreaking, it was the death of Apollo Creed. To start Rocky IV, Apollo takes on the The Siberian Bull in an exhibition match. In the fight, Drago overpowers Creed with a barrage of punches. By the start of the second round Drago continued to pummel Creed with ease. Rocky contemplates whether to "throw in the towel" and surrender the fight (against Creed's earlier instructions), but instead he decides to hold onto the towel while his friend, limp and unable to defend himself, continues to absorb blows to the head until he is finally killed. Drago exhibits no remorse whatsoever about what he does to Creed, simply stating in an interview after the fight that "if he dies, he dies."
But that brings up the question, did Ivan Drago really kill Apollo Creed? or did Apollo Creed kill Apollo Creed, with assistance from Rocky Balboa and an incompetent referee?
