THE SPIDERMAN 3

Peter Parker has begun to feel secure in his life and plans to propose to Mary Jane. While Peter and Mary Jane are on a date, a small meteorite crashes nearby, and an extraterrestrial symbiote attaches itself to Peter's moped. Meanwhile, escaped convict Flint Marko falls into a pit of a particle accelerator that fuses his body with the surrounding sand. The result allows him to shape shift at will, becoming the Sandman. Peter's best friend, Harry Osborn, who seeks vengeance for his father's death, which he believes Peter caused, attacks him using new weapons adapted from the Green Goblin technology his father had left behind. During the scuffle, Harry injures his head and suffers from partial amnesia, making him forget his vendetta.
Later, during a festival honoring Spider-Man for saving Gwen Stacy's life, Sandman attempts to rob an armored car, and overpowers Spider-Man. Gwen's father, police officer Captain Stacy, later informs Peter and Aunt May that Marko is the one who killed Ben Parker. A vengeful Peter waits for Marko to strike again. The symbiote bonds with his costume while he is asleep; Peter wakes up hanging from a skyscraper in central Manhattan and discovers that not only has his costume changed, but his powers have been enhanced as well. Perhaps capitalizing on Peter's current conflicted and anguished state of mind, the black suit brings out the more vengeful, selfish and arrogant side of Peter's personality. Wearing the new suit, Peter locates Flint Marko, fights him in a cavernous underground subway tunnel and, upon discovering that water can dissolve Marko's body, rips open a large water pipe to deliver what he believes to be a lethal torrent of water, reducing the Sandman to mud.
The shift in Peter's personality alienates Mary Jane, whose career is floundering, and she finds solace with Harry. Harry recovers from his amnesia and, urged on by an apparition of his dead father, forces Mary Jane to break up with Peter. After Mary Jane leaves Peter, stating she is in love with another man, Harry meets him at a restaurant and claims to be the other man. Later, Peter confronts him at the Osborn mansion. With the help of the black suit, Peter is victorious in a brutal fight, which leaves Harry's face disfigured. Influenced by the suit, Peter exposes and humiliates Eddie Brock, a rival freelance photographer, who has just gained overnight star status at the The Daily Bugle by submitting doctored photographs supposedly showing Spider-Man to be a criminal. J. Jonah Jameson gets wind of the photos and Jameson fires Eddie Brock. Peter changes how he dresses and alters his hairstyle and begins to behave like a conceited lout. Meanwhile, the Sandman recovers from his injuries, having somehow survived Spider-Man's attack.
