Dr. Weird is a character in which Adult Swim cartoon?

Dr. Weird is a character in the Adult Swim cartoon Aqua Teen Hunger Force. He is a flamboyant mad scientist who appears primarily in the show's early cold openings.

Dr. Weird lives in an abandoned mental asylum and conducts bizarre experiments, often shouting strange declarations before unleashing a new creature or invention. His assistant, Steve, usually stands nearby in a lab coat and goggles. The character's chaotic appearances established the show's surreal, absurdist tone before the main story shifted to the Aqua Teens.

The Aqua Teens are Frylock, Master Shake, and Meatwad, three food-shaped characters who live next door to Carl. Although Dr. Weird is not part of the central trio, he is closely tied to the series' mythology. The feature film reveals an unusual connection between him and the Aqua Teens' origins.

The title can cause confusion because Dr. Weird is also used by unrelated comic-book and radio characters. In the Adult Swim context, however, the answer is specifically Aqua Teen Hunger Force.
