<P> Creator Danny Antonucci explained Ed's inspiration saying, "Ed is...me, following his own path and slightly dysfunctional, a daydreamer who while people are doing one thing, will be busy thinking of another ." He also described Ed as "slow, living in his own world and he really doesn't fit in with the rest of the crowd," and explained that it was hard to decide who would voice him . Ed ended up being voiced by Matt Hill . </P> <P> Jonny, also known as Jonny 2x4 (David Paul Grove), is a loner and considered by his peers to be a nuisance . Jonny is often made fun of for his big head (Eddy usually refers to him as "Melonhead") and has a tendency of getting his head caught in branches when climbing trees . He talks a lot, and frequently gets on the other kids' nerves . He is rarely seen without his imaginary friend, a 2x4 wooden board with drawn - on eyes and a mouth, aptly named Plank . Jonny seems innocent and gullible, and often forgives people no matter what they do . He does not seem to mind the antics of the Eds, and is often the most friendly out of all the cul - de-sac kids towards them . He is very protective of Plank, and will burst into acts of bravery or extreme aggression if Plank is stolen or harmed in some way . He does not seem to acknowledge that Plank is just an inanimate, silent, 2x4 piece of wood, and when asked for help with an imaginary friend, he claimed to have no clue what the Eds are talking about . He and Plank both have superhero alter egos (Captain Melonhead and Splinter the Wonderwood, respectively), which they assumed twice throughout the series; first in "Robbin' Ed" to thwart Eddy's "Thingamajig" scam and to fight Eddy's own one - time only alter ego, Professor Scam, and then in "Ed, Edd n Eddy's Big Picture Show" to hunt down and get revenge on the Eds . After "Big Picture Show," he and Plank become The Gourd and Timber the Dark Shard in order to take revenge on the entire cul - de-sac . </P> <P> Jimmy (Keenan Christenson) is an insecure child, with a propensity to cry, and Sarah's best friend whom he is most often seen spending his time with . Jimmy is highly accident - prone, often seen sporting bandages, casts, and braces (particularly headgear), and is considered the weakest kid in the cul - de-sac . Though Jimmy has a cowardly, delicate, and effeminate personality, he truly wishes to be strong and muscular, and many episodes demonstrate his desire for fame and stardom . He can be crafty when motivated, and had twice made scams that were very successful . Jimmy has shown how deeply attached he is to Sarah when someone tries to take her away from him . For most of the series he wore a retainer to correct his teeth, due to a bowling pin accident during one of Eddy's scams . </P> <P> Sarah (Janyse Jaud) is Ed's grouchy, abusive, spoiled, short - tempered, whiny, and extremely selfish younger sister who acts cute and kind to the Eds only when it suits her . She is commonly depicted with a disgruntled facial expression and treats her intimidated, trembling older brother, frightened by his sister's constant threats of tattling on him, with complete disdain . Imposing, Sarah frequently orders people (sometimes even those of higher rightful authority than her) around, and her desires often have to be met or else she will fling herself into a violent temper tantrum or threaten the person in question . Throughout the course of the series, Sarah has been shown to possess an infatuation with Edd, but still occasionally subjects him to abuse due to guilt by association with the other Eds . </P>
