Di Lung is a young Chinese inventor and the creator of Mecha Courage. He is very inconsiderate and rude, and usually gets caught in the middle of the chaos going on in Nowhere. He has twin aunts; one evil and the other good. Di Lung is voiced by Tim Chi Ly, who also serves as one of the show's animators. He is known for saying, "Watch where you're going, you fool!" and his distinctive laugh.
While primarily a cameo character, he has a larger role episodes like Courage the Fly where he "invents" a potion that makes Courage a fly, and Courage vs. Mecha Courage, where he invents the "Mecha Courage."
