three adolescent boys collectively known as "the Eds," who hang around in a suburban cul-de-sac. Unofficially led by Eddy, the Eds constantly scheme to make money off their peers, in order to purchase their favorite confectionery: jawbreakers. However, their plans usually fail, leaving them in various predicaments. Eddy is a greedy, ill-tempered con artist and loudmouth, the self-appointed leader of the Eds. He goes to great lengths to scam the other kids out of their money, even at the expense of his friends' credibility. His efforts are all in the pursuit of jawbreakers, which he loves as much as he does money. He is very sensitive about his short stature, suggesting that he may have a Napoleon complex. Eddy detests school, and more than once has tried to escape. His report card labels him a megalomaniac. Eddy loves his retro styled room, complete with a lava lamp, a large round king-sized bed, a disco ball, and a record player. Eddy is mostly seen commanding the two Eds into building the scams while he usually does non-physical work or simply sits around. It is shown that Eddy cannot learn from his mistakes; on several occasions, he taunts and insults Sarah to the point where she loses her temper and attacks him. Edd (commonly referred to as Double D) is a young inventor, neat freak. The most intelligent of the trio, he is never seen without his head covered in some manner, almost always by his trademark sock-like black ski hat, hiding a secret unknown to everyone besides Ed and Eddy, which they learned in the episode "Stop Look Ed", when Eddy tied Edd's hat to a ceiling fan, and when he tried to get to Eddy it came off of him; he quickly covered himself back up, telling them never to tell anyone what they saw. While there have been vast fan-based speculations on what is under the hat, nothing has been officially revealed by the show's creators. He also has a significant gap in his teeth, which he sometimes gets things stuck in, to his embarrassment (see "Key to My Ed"). Because of his moral center and good heart, he is typically more socially accepted by the other inhabitants of the cul-de-sac than Ed and Eddy are. Ed is the strong, dimwitted workhorse of the group. His skin is yellow, unlike the other characters and he is known to laugh a lot and is happy most of the time. Ed has amazing physical strength which is humorously worked into many of the show's plots. His mind is a subculture grab bag full of comics and monster movies, which he often confuses with reality and also having the habit of shouting random remarks which have almost nothing to do with the current conversations.
The three Eds are all Sentinel Cadet in training. They still scheme from time to time, and tend to sneak Jawbreakers into the acadamy.
