Edd (also known as "Double D", or "Sockhead") is from the show Ed, Edd 'n' Eddy. In the show, he is the most intelligent and well-behaved member of the Eds. He is the one doing the engineering work for Eddy's plethora of schemes, and is also the brains behind them.
FusionFallHe appears in FusionFall, but makes no appearance in any of the Future Areas, hinting that Edd might have fell or got captured along with Ed and Mac. This implies that he hadn't survived to the point of Tech Square's fall. Instead, he is a Guide the player encounters in the past.
While Eddy proclaims himself to be the King of the Cul-De-Sac, Edd is much more of a leadership position. He was the one who set up the Cardboard Fortress that surrounds the Cul-de-Sac. Edd is never seen without his sock hat, raising eyebrows about what secrets lie beneath it. His eye color is also unconfirmed.Choosing him as a Guide will give the player access to missions involving finding buried candy treasure or learning secrets, meanwhile having the player hide the candy so as not to let Fuse take it. The candy that the player first discovers is a cursed candy that causes its consumer to go slightly insane. If Fuse were to gain this power, he would be able to weaken the heroes' defenses. Edd finds help from other characters, such as Bloo, when he agreed to help read one of the treasure maps; Billy, who also helps read a map that leads the hero to the Eternal Meadows infected zone; and Stickybeard, who tells the tale of the cursed candy. Courage and Samurai Jack also eventually help when some of the candy is found by Fuse's monsters and taken to the Darklands. Edd also offers valuable assistance to Dexter, as he was the one who first found the Power Level tracker, a device that Dexter used to track down missing heroes such as Samurai Jack and Buttercup. Edd appears as a hologram in Hero Square in the Future, along with Ben, Dexter, Mojo Jojo, and Bloo. He is mostly likely featured because he was a guide, and also possibly for building the Cul-De-Sac Castle. He is also on Mt. Neverest, greeting the hero in the "Meet Edd" mission.
Edd as Guide
Guide Edd is for players who like fun and candy treasures — but not only fun, for more than just that will be needed to destroy Fuse.
