Edd has straight brown hair with points in some parts and wears a green hoodie with laces and brown khakis. Edd's shoes are green with laces. He wears a white "Smeg Head" shirt under the hoodie. Overall, Edd's portrayal is inconsistent throughout his appearances. He is sometimes portrayed as carefree, adventurous, and/or self-centered depending on the situation. One of Edd's more consistent characteristics is a strong obsession with Coca-Cola and Bacon. Edd is portrayed as more generous and kind.

Matt has ginger hair and a square chin. Matt used to wear either a black t-shirt, then a black hoodie, as well as a green overcoat, blue jeans, and black shoes. In Zanta Claws, Matt received a purple hoodie as a Christmas gift from Santa. Matt has worn the purple hoodie and a green overcoat since then. In the Eddsworld theme video, Matt wears a black "I ♥ M@" shirt. Matt is the second tallest compared to Edd, Tom, and Tord. Matt is generally portrayed as narcissistic and picky about looks. Matt can be smart or stupid depending on the situation and likes to hoard stuff. Matt appears to be slightly nicer but more dimwitted. . In "Fun Dead", Matt went as far as to name a cymbal playing monkey earned from a claw machine "Little Tom", only for Tom to destroy the monkey shortly afterwards. In the same episode, Matt told Edd "If I don't make it, I want you to give my novelty toy collection to Tom.", only for Tom to reply "And if I don't make it either, please BURN my new novelty toy collection." In part two of "The End" Matt uses the control panel to make Tord's robot punch itself for 3 reasons; 1. Destroying Edd's house 2. "Killing" a friend (Tom) 3. Tord punching Matt in the face..

Tom wears a blue hoodie, large spiky hair (he called it "Steve" in Moving Targets), no eyes, and a spherical head. Sometimes, Tom is shown to have dark blue jeans whereas at others to have normal grey leg-wear. He wears checkered shoes which are the set out the same way as a chess board. Tom is the shortest compared to Edd, Matt, and Tord. Tom's eyes started off as a black line, but later transitioned into empty, black sockets. He inherited this peculiar trait from a bowling ball (considered Tom's "mother"). Tom seems to have a more consistent portrayal throughout his appearances. Tom is generally portrayed as cynical, pessimistic, and cold. Tom can be smart or stupid depending on the situation. Tom does not usually get along with others such as Matt or Tord, and does not enjoy Christmas. Tom is addicted to alcohol, particularly Smirnoff, and cares deeply for a bass guitar (which Tom calls Susan). In "Fun Dead", Tom's "mother" was a bowling ball and Tom's "father" was a pineapple, explaining the lack of eyes and spiky hair
