Jalome Beacher was a talented chemical engineer who worked for the Beemont Manufacturing in New York City. He eventually took his life through crime, calling himself Slyde. Eventually, he was stopped by Peter Benjamin Parker and sent to prison. During the recent Avengers Civil War, Jalome was released from prison when he chose to register his name in the Sokovia Accords. Given a full pardon from his crimes, he joined the Thunderbolts, in which his job was to search for enhanced people, villains, and unregistered heroes, and have them all arrested or registered. However, he was captured by the Revengers and executed by Dmitri Anatoly Nikolayevich Smerdyakov under William Cross' orders.
