Darius Dun is a character in the Teenage Mutant Ninja Turtles comic series by IDW Publishing. In issue #64, Darius Dun is captured during a raid by Splinter's Foot Clan. Splinter offers to spare Dun's life if he surrenders all of his assets to the Foot Clan, but Dun refuses. Splinter then coldly orders Jennika to execute Dun on the spot. This killing prompts Splinter's sons, Leonardo, Raphael and Donatello to cut ties with Splinter and the Foot Clan, which Michelangelo had already done in issue #50.
