Eddy's Brother is an unseen character from Ed, Edd n Eddy who appears in its TV movie finale, Ed, Edd n Eddy's Big Picture Show.
He was previously an unseen character, and is the only one of the series adults that has been both seen and heard. Aside from the Kanker Sisters, he is the real main antagonist of the series. He has a deep, smooth voice and a room that Eddy hopes to inherit and reside in. His room is complete with a car and all kinds of memorabilia and strange items. For example, he owns a pet snake, a giant dusty taxidermy camel, a brick-covered window, a bed that folds-up into the fridge, and a (now broken) trophy (unknown for what, but it might be chewing ice cubes because Eddy said before Ed saw the trophy that he was a whiz at chewing Ice cubes.), however in Ed, Edd n Eddy's Big Picture Show it is seen on the floor unbroken. He is probably over 18 due to the fact that he owns a car and doesn't live with his parents. He may have a kinship with the Kanker Sisters, as he was able to set Eddy up to go to their trailer for a prank, but this is unlikely because the Kankers moved in after Eddy's brother was gone. He also tries to scam everyone similar to Eddy, but much more successfully. His room is guarded by a chained lock, pieces of wood nailed to the wall, and a falling safe, and along with the fact that it was camouflaged to blend in with the rest of the wall. The door to his room is hidden behind wallpaper for some reason.
In some of the early seasons, many fans didn't think he was "real". He has his first appearance in Ed, Edd n Eddy's Big Picture Show. He is one of the few people whom Kevin fears probably because of his strength and due to the stories Kevin has heard about him. Eddy's Bro wears a red plaid jacket, and a tweed cap. He also has some hairs on his rather large chin, and he also has three hairs sticking out from the back of his head just like Eddy.He resides in the costal theme park Mondo A-Go Go in a trailer (Eddy's Brother's Trailer).
Although a major antagonist Eddy's Brother actually appeared only for a brief period of time in the movie itself and was originally playing to Eddy's original stories of being benevolent and protective of his little brother - however he quickly demanded that he and Eddy "play uncle" and twisted Eddy's leg around painfully.
Edd was horrified while the Kanker's became angered - the other kids also seemed upset (save for Ed, who was too oblivious to understand what was happening): after Eddy's Brother began to violently smash Edd against the door of his trailer Edd decided to confront him only to be beaten by the much larger male.
This made even Ed realize what was happening and the other children rose against Eddy's Brother in an effort to protect Eddy - however he was far too strong for them to take down without risk of injury, luckily Ed (in a rare moment of genius) finally had enough and pulled out one of the bolts holding the door to the trailer.
The door proceeded to catapult out and slammed into Eddy's Brother face, knocking the brute out - his final words being "uncle".
While the other kids celebrated their victory the Kanker Sisters dragged Eddy's Brother away to an unknown fate..
There have been clues about Eddy's older brother throughout the show: in season one's "Fool on the Ed," we learn that Eddy's brother showed him how to make the special-recipe El Mongo Stink Bomb, "before he went away," and in season two there's a glimpse of a picture on Eddy's wall - 2 boyish silhouettes, one bigger than the other. The biggest clue lies in the episode "Ed in a Halfshell" where Eddy sets himself the task of making Jimmy his protégé, and we learn that Eddy was himself molded in just this way by his older brother.
Season three provides an abundance of brotherly details, starting with the episode "O-Ed Eleven" where we get to see hallowed ground - Eddy's brother's room. The decor is just as unique and twice as bizarre as Eddy's room, and gives hints towards how multifaceted he appears - from bouzouki playing to bricklaying, from chewing ice cubes to ticking off Eddy, his big brother has a lot of unknown tales to be told. In the episode "An Ed is Born," Eddy gets a care package that shows just what Big Bro thinks of his baby brother, and perhaps Eddy's "No more beating up little Eddy!" comment at the end gives us a pretty good idea of just where he got that knack for shoving around his pals. And how could we talk about Eddy's brother without mentioning the stir caused by rumors of his return in the episode "Ed, Pass it On"? Not since the Kankers went on their latest hissy fit had the whole neighborhood been in such an uproar – Rolf digs a moat and knits a very special offertory vest to protect his chickens, Nazz gleams at the prospect of having someone as rad as Eddy's brother to hang with, and even tough-guy Kevin disintegrates into a groveling coward as he ponders the implications of Big Brother's return. You've got to admit, Eddy's brother seems to give off a foreboding aura.
He sent Eddy a box of baby-related items like a pacifier and a rattle in the episode "An Ed is Born", which shows less chance that Eddy is actually respected by his brother (social issue). His true nature is shown in his first on-screen appearance in Ed, Edd n Eddy's Big Picture Show.
In Ed, Edd n Eddy's Big Picture Show, after Edd analyzes all of stories Eddy has told him of his brother, Edd comes to the conclusion that Eddy's Brother is a prankster. However, during the end of the movie Eddy's Brother's true colors are revealed. He is indeed a huge jerk. He makes fun of Edd by calling him Eddy's girlfriend, and then proceeds to bully Eddy continuing the stereotypical dysfunctional older brother/younger brother relationship, although it must be noted that his beatdown, though cartoonish in several ways, shows that he is a very sadistic person, to the point of being downright evil, as there was literally no reason for him to do that to his brother, he just played "Uncle" as an excuse to hurt his little brother, his experiences with Eddy may actually have severely injured Eddy. However, this ends when Ed pulls out a hinge that is barely holding onto Eddy's Brother's trailer and it ends up slamming him in the face (with Eddy still clinging to the door in fear) and knocking him out cold.
