Ed, Edd, n Eddy's Ed-ventures of Spider-Man 3

Ed, Edd, n Eddy's Ed-ventures of Spider-Man 3 is the third and final upcoming Ed, Edd, n Eddy/Spider-Man crossover to be made by Stuingtion. And a sequel to Ed, Edd, n Eddy's Ed-ventures of Spider-Man 2.

Plot
Peter Parker plans to propose to Mary Jane Watson, who has just made her Broadway musical debut. A meteorite lands at Central Park, and an extraterrestrial symbiote follows Peter to his apartment. Harry Osborn, seeking vengeance after his father's death, attacks Peter with weapons based on his father's Green Goblin technology. The battle ends in a stalemate, with Harry crashing out and developing amnesia, wiping out his memory of Peter as Spider-Man. Meanwhile, police pursue escaped prisoner Flint Marko, who visits his wife and dying daughter before fleeing again and falling into an experimental particle accelerator that fuses his body with the surrounding sand, transforming him into the Sandman.

During a festival honoring Spider-Man, Peter kisses Gwen Stacy, infuriating Mary Jane. The superpowered Marko robs an armored car and Peter confronts him. Initially warning him to leave to avoid battle, Marko easily subdues him and escapes. NYPD Captain George Stacy informs Peter and Aunt May that Marko was Uncle Ben's true killer; the deceased Dennis Carradine was Marko's accomplice. While a vengeance-obsessed Peter sleeps in his Spider-Man suit, the symbiote assimilates his suit. Peter later awakens and discovers his costume changed and his powers enhanced; however, the symbiote brings out Peter's dark side. Wearing the new suit, Peter locates Marko and battles him in a subway tunnel. Discovering water is Marko's weakness, Peter breaks a water pipe to reduce Marko to mud, washing him away and believing him to be dead.

Peter's changed personality alienates Mary Jane, whose career is floundering, and she finds solace with Harry. Harry recovers from his amnesia and, urged by a hallucination of his father, blackmails Mary Jane into unwillingly breaking up with Peter. After Mary Jane tells Peter she loves "somebody else", Harry meets with Peter and claims to be "the other guy". Later, Peter, wearing the black suit, confronts Harry about forcing Mary Jane to end her relationship with him and spitefully tells Harry his father never loved him. Another fight ensues, in which Harry throws a pumpkin bomb at Peter, who deflects it back, disfiguring Harry's face.

Under the symbiote's influence, Peter exposes photography rival Eddie Brock, whose fake photos depicted Spider-Man as a criminal. Soon afterward, to make Mary Jane jealous, Peter brings Gwen to the nightclub where Mary Jane now works, but Gwen catches on and leaves. Peter brawls with the bouncers and, after accidentally hurting Mary Jane, realizes the symbiote is corrupting him. Retreating to a church bell tower, he discovers he cannot remove the suit, but that the symbiote weakens when the bell rings. Peter removes the symbiote and it falls to the lower tower, landing on Brock, who had been praying for Peter's death. The symbiote bonds to Brock, transforming him into Venom. Brock locates Marko and convinces him to join forces to defeat Peter. Brock then hijacks a taxi with Mary Jane on board, and hangs it as bait from a web above a construction site, while Marko keeps the police at bay. Peter seeks Harry's help, but is rejected. While Peter battles Brock and Marko, Harry learns the truth about his father's death from his butler, and goes to help Peter as he is being overpowered, resulting in a battle between the four. Harry subdues the Sandman before assisting Peter against Brock. In the ensuing battle, Brock attempts to impale Peter on Harry's glider, but Harry intervenes and is impaled himself. Remembering the symbiote's weakness, Peter assembles a perimeter of metal pipes to create a sonic attack, weakening Venom and allowing Peter to separate Brock and the symbiote. Peter activates a pumpkin bomb from Harry's glider to destroy the symbiote, but Brock dives in, and the bomb kills them both.

Peter confronts Marko, who explains that Uncle Ben's death was an accident and has haunted him ever since. Peter forgives Marko, who then leaves. Peter and Mary Jane witness Harry, who dies beside them. Peter, Mary Jane, and Aunt May attend Harry's funeral. Later, at the nightclub, Peter and Mary Jane reconcile.
