Cosmic Silverback

The Cosmic Silverback is a zombie silverback gorilla in the Call of Duty: Black Ops zombie map Dead Ops Arcade.

Dead Ops Arcade
The Cosmic Silverback is the primary antagonist of Dead Ops Arcade, where he serves as the final boss at round 40. He will also appear at the end of a round, usually every five rounds, in an attempt to kill the players; he can be deterred at these times if the player(s) shoot at him and keep their distance, or if they move to the next round. He will appear again when the players see their final scores after they all run out of lives, this time crushing the player with the highest score and stealing all of their treasure.
