Dr. Weird is a supporting character and main antagonist in the show Aqua Teen Hunger Force. For the first two seasons of the show, he was the subject of its cold openings. He rarely appears outside the cold openings.
Dr. Weird wears a purple and green robe, with a W-shaped hole in the front. He also has a "hairarium" or hair heater around his head. He has white hair that somewhat forms the shape of a W. Reminiscent of super villains from the 1960s and 1970s, Dr. Weird has a mask that covers his eyes, which appear to be solid red. He also wears gloves.
First and foremost, Dr. Weird is completely insane. In the series premiere, Dr. Weird invented the Rabbot to take care of the world's "vegetable problem." In the film, Dr. Weird and his assistant Steve, who Dr. Weird's lab assistant and occasionally his guinea pig, dressed up in various disguises. At one point, while Dr. Weird was wearing a chicken disguise that was actually the size of a chicken, Steve remarked, "That's my wife." It is never fully explained what this means. It could be possible that Dr. Weird forced Steve to marry him (although later in the film, Steve later remarked that his wife wanted him home by a certain time, implying that this is not true). It could also be possible that this was a backstory formulated by Dr. Weird to make the disguises more believable.
When the show began, the cold openings would feature Dr. Weird shouting "Gentlemen, BEHOLD!!" to Steve and no one else, then he would usually demonstrate something that would be used later in the episode, such as the RainbowMaker 400 in "Escape From Leprechaupolis" or MC Pee Pants in the episode of the same name. By the end of Season One, however, the cold openings with Dr. Weird and Steve were changed to utter nonsense. They had nothing to do with the following episode, and nothing in them made sense. Of course, not making sense has always been Dr. Weird's main personality trait.
Powers and Abilities?Edit
Although it is never fully addressed in the series, Dr. Weird seems to have some manipulation over the laws of physics and logic in general. While Frylock's science experiments usually have some base in real-life science, Dr. Weird seems to completely defy science. For example, in "Revenge of the Trees," a gigantic version of Dr. Weird's head eats Steve, whose body falls on Javier (Dr. Weird's hispanic janitor) and explodes. In "Super Bowl," Steve pops out of Dr. Weird's body, yet Dr. Weird is perfectly fine. In the film, he was able to fit himself into a chicken outfit that was the size of an actual chicken. He is also, presumably, the creator of a moth-human hybrid known as Mothmonsterman, and a monster made to look like a present. He also has a blue gas inside of him that is seen in multiple cold openings.
Failure to ReturnEdit
It was announced at a convention  that there would be Dr. Weird cold openings for Season 8. He and Steve did appear in the cold opening of the first episode of Season 8, but Dr. Weird didn't return for "Allen Part Two" nor any of the other Season 8 episodes; though, one can see Dr. Weird in the opening sequence of Aqua Unit Patrol Squad 1 after Meatwad morphs into a machine gun. At this point, it is highly unlikely for Dr. Weird to return. A similar fate befell Mr. Beefy who was confirmed via Dave Willis's Twitter account to appear in every episode of that season, despite appearing only once in "Allen Part Two."
- Even though in the film Dr. Weird said he was created by Frylock and that they were creations of Walter Melon, it was confirmed in 2010 during "Aqua Teen Hunger Force Live" by series creator Dave Willis that Dr. Weird was indeed the creator of the Aqua Teens, making them brothers. Thus confirming that Weird's confession was just another one of his insane rants and that Walter Melon was simply one of his creations used for his insane and convoluted plot to mess with the Aqua Teens. 
- In the cold open for the episode The Dressing, Dr. Weird kills Space Ghost and uses his head as a mask. This is humorous because Weird's voice actor C. Martin Croker potrayed Zorak on Space Ghost: Coast to Coast, and because Matt Maiellaro and Dave Willis were writers on Space Ghost: Coast to Coast.
