Jalome Beacher was a chemical engineer who created a non-stick coating that could be applied to anything, only to be fired by his employers. He created a costume coated in the substance and decided to use it to rob banks. His all-white bodysuit allows him to slide across floors with relative ease, and renders him impervious to Spider-Man's webbing. The suit has pads on the gloves so that Slyde can grip objects without them slipping from his grasp. Slyde was part of the seventh such group called the Masters of Evil when the villainous assemblage tangled with the Thunderbolts, ironic because the Thunderbolts are mostly made up of reformed members of the Masters of Evil. Upon the realization that he was turning forty soon, he got a new costume, gave himself a new origin, and made an attempt at robbing a bank with henchmen—but it was all a ploy to lure Spider-Man out in order to fight him. At the end of the story, on the way to jail, he mused that, knowing that he "went toe to toe with Spider-Man", he is entirely all right with middle age. In Wolverine #26, Slyde was apparently killed by the sword of Elektra who was presumed dead/resurrected by The Hand. This was later revealed to be Jalome's stepbrother Matt, wearing Jalome's costume and using the Slyde identity while Jalome was in prison.
Slyde is among the army of villains recruited by Zemo and his Thunderbolts to serve as "hero-hunters" during the events of the Civil War. Jalome, as Slyde again, along with the Trapster, met with mob bossHammerhead, who was attempting to organize a group of super-criminals to take advantage of the Civil War between the Marvel superheroes. However, Slyde balked at the proposal. He was shot in the back of the head and apparently killed by Hammerhead's enforcer Underworld, in order to send a message to those who would refuse to join Hammerhead's organization.
Other characters named Slyde
Following the death of Beacher, another person assumes his costumed identity. The identity of this Slyde is unknown, but he appears in Jalome's costume and was seen on the cover of Avengers: The Initiative #1 as one of the 142 registered superheroes. Slyde's appearance however is not proof of his involvement in the Initiative, or may mean the Slyde costume has passed on to an heroic successor.
A new version of Slyde appeared though the costume was now completely blue. After a brief chase with Spider-Man, it was revealed that this Slyde was an undercover police officer.
Ripcord
After M-Day, the second Night Thrasher gave several former mutants technology he had obtained using the organization he owned. Former prostitute and mercenary Stacy X was given a modified Slyde suit, along with modified Stilt-Man armor, web shooters, and Frog-Man springs. She became a New Warrior, died in an explosion during battle, but later resurfaced again with her Stacy X appearance.

Television
Slyde appears in the Spider-Man episode "The Road to Goblin War," voiced by Phil LaMarr. In this show, Jalome Beecher is a former worker at Beemont Chemical Corporation who was fired by the company's CEO Alan Beemont for wanting credit for what he developed for the company. When Spider-Man first encounters Slyde in his revenge on the city, his webs can't affect him. Slyde gets away by causing a fire escape to collapse causing Spider-Man to save the people from getting crushed. His next attack is at the park where he manages to jam Spider-Man's web-shooters. With help from Otto Octavius, Spider-Man traced the chemicals that Slyde uses to Beemont Chemical Corporation where he is unable to get any information about Slyde from Alan Beemont. The corporation's CTO Dr. Joseph Rockwell speaks to Spider-Man where he revealed Slyde's origin. When Slyde attacks again, Spider-Man rescues people from the explosives that were set off. Thanks to Otto, Spider-Man finds Slyde's secret hideout at Beemont Chemical Corporation as the Octobots use special chemicals to counter Slyde's chemicals enabling Spider-Man to web him up. It is then discovered that Slyde was in cahoots with Dr. Rockwell so that Beemont would be fired and the Goblin Nation would take over. Slyde and Dr. Rockwell are arrested by the police.
