Dr. Daniel Clarke is a minor antagonist in the video game Call of Duty: Black Ops. He worked for Nikita Dragovich on Project Nova where his expertise in biology and chemistry came to play, primarily to stabilize certain volatile components in the Nova-6 gas. In Kowloon, Hong Kong, he was interrogated by Hudson and Weaver but they were attacked by Spesnaz forces intending to kill Clarke from Dragovich to help him tie up loose ends. The three escaped from the ambush, but with Clarke's stashed weaponry, they fended off the Spesnaz, but Clarke was killed before he could tell Hudson what Dragovich had planned by a sniper.
