Edd, mostly referred to by his nickname "Double D," is one of the three protagonists in Ed, Edd n Eddy. He is the physically weakest but the most intelligent member of the Eds.
Role in the series
Edd is a rather scrupulous, but kind and good-intentioned youth. Docile, polite and disciplined, he willingly adheres to the laws and regulations of his community. With his love and desire for order, he occasionally undertakes the role of a peacemaker. He is incredibly gentle and accepting, albeit sometimes awkward and timid in his interactions, particularly with people of the opposite sex. Although considered an outcast, he is a generally well-respected, if not appreciated, member of his peer group, whom he gladly counsels and assists if need be. Even so, perfectionist Edd is something of a "goody-two-shoes," wishing to please and accommodate to the needs of others.
Edd is quite delicate and mysophobic, disliking any potentially "harmful" form of physical activity and among all, contamination. He will go great lengths to cleanse his environment, and exhibits numerous idiosyncrasies; among these odd habits are his tendency to name tag his every possession, to the extent of claiming to "not be able to rest in an unlabeled setting." He has a significant dislike of sports as well, rooted perhaps from an infamous, scarcely mentioned dodgeball incident from his childhood.
What Edd lacks in physical strength is substituted by his intelligence, in a total reversal of the dim-witted yet physically stronger Ed. Exceptionally precocious, Edd is a promising young inventor with an interest in science. Although clever and perceptive, his foresights are often denied by an insidious Eddy. It is then that he displays his characteristic neuroticism and sarcasm, to the chagrin of his friends. Edd has also proven on many occasions to be quite brave. In "The Day the Ed Stood Still," he volunteered to potentially sacrifice himself to make up for his creation of Monster Ed. In the movie, he is among the first to stand up to Eddy's Brother while he was torturing Eddy.
In earlier episodes, he was a little more laid back and a lot more soft-spoken, he was also much more subservient to the whims of Eddy. However, as time wore on and his character expanded, he not only became more understanding and disciplined, but also more sarcastic and insubordinate to Eddy. He also began to talk a lot more than he used to. His quirks were also played up a lot more as well, such as his intelligence, his perfectionism, and his obsessions with order and cleanliness.
He also gets upset when people are better than him in something he excels at, as seen in "Ed in a Halfshell," "Too Smart for His Own Ed," and "In Like Ed."
