From now on, we're poison to Peter Parker and Spider-Man! We're Venom!
Edward "Eddie" Brock, also known as Venom, is one of the secondary antagonists (the others are Hammerhead, Doctor Octopus and Rhino) of the animated TV series The Spectacular Spider-Man.
He was a childhood friend of Peter Parker that grew to resent Peter over a series of events. After bonding with the symbiote, they became Venom, terrorizing New York City to become one of Spider-Man's greatest archenemies along with Green Goblin and Doctor Octopus.
Eddie was shown to be cool, friendly and brotherly to Peter Parker and Gwen Stacy. However, due to events in the series, he resented Peter and bonded with the symbiote becoming Venom to attack Spider-Man and his loved ones before attempting to expose Spider-Man's identity becoming one of Spider-Man's greatest opponents along with Green Goblin and Doctor Octopus.
Eddie Brock was a childhood friend of Peter Parker until both their parents died in a plane accident. However, Peter lived with Aunt May and Uncle Ben while Eddie had nobody to take him in which made him resentful of Peter living the easy life. However, he changed his attitude years later.
In Season 1, Eddie worked a ESU labs and was happy to see Peter and Gwen Stacy. However, due to different events, Eddie began to show animosity to Peter due to misunderstandings when it came to Peter taking photos while he was secretly Spider-Man thus damaging their friendship.
While trying to stop Black Cat from stealing a symbiote at ESU labs, it bonds with Spider-Man. Due to the symbiote's disappearance caused a loss of funding at ESU and Eddie was let go. Spider-Man begins to enjoy having the symbiote due to it enhancing his powers and taking out villains like Chameleon, Quentin Beck, Tinkerer and the Sinister Six. However, after finding out that the symbiote makes its host hostile and aggressive especially to people around them, Spider-Man returns it back to ESU a freezes it. Unfortunately, Eddie unfreezes it and bonds with it, becoming Venom. After learning from the symbiote's memories from its last host, Eddie finds out that Spider-Man is Peter and swears revenge on him. After having Tombstone hire him to kill Spider-Man, he attacks the latter at home while revealing that he knows about his loved ones. After a brawl at the hospital where Aunt May is, Venom reveals that he knows who he loves the most. Spider-Man believes it to be Mary Jane but it's revealed to be Gwen Stacy when Venom ties her to a parade float to lure Spider-Man into a battle with him. However, Spider-Man saves her and tricks the symbiote into leaving Eddie and buries it in cement.
In Season 2, Eddie returns stalking Peter and dressing up as the Black Suit Spider-Man to frame him for a few crimes. He then secretly has Peter lead him to the buried symbiote where he uncovers it and bonds with it again.
He later attacks Spider-Man on a roof before escaping. He then attacks the Daily Bugle and reveals that Spider-Man is Peter Parker. Venom then began attacking Spider-Man to unmask him in front of people but keeps failing. Deciding to cure Peter of his powers, Venom takes a vial of a cure used to cure Dr. Curt Connors. He attacks Spider-Man at Midtown High where Spider-Man with Flash Thompson's help, removes the symbiote from Eddie again. Fortunately, Peter's identity as Spider-Man is safe again and Eddie is taken to an asylum after being declared insane while the symbiote stalks the sewers.
It is unknown what will happen with Eddie and the symbiote, but it is very possible he could've returned again if the series would've continued with more seasons with Carnage having planned to appear in Season 3.
