Antoine Desloin is the lead singer of the Mercy Killers, going by the name of Hypno-Hustler. He and his band are scheduled to perform at a nightclub called "Beyond Forever".

When the club's manager catches Hypno-Hustler robbing his safe, he used his hypnotic equipment on the manager.

When it comes time to perform, Hypno-Hustler and his band use their hypnotizing equipment on the audience in a plan to rob them as well. Peter Parker is at the club at the time and changed into Spider-Man.

During the fight, Spider-Man discovers that Hypno-Hustler's headphones protect him from his own music. Spider-Man manages to remove the headphones from Hypno-Hustler, causing him to become a victim of his own hypnosis.

When the audience is free of the hypnosis, Hypno-Hustler and his Mercy Killers are webbed up and left for the police.

Hypno-Hustler later appears at a Vil-Anon meeting with Armadillo, Big Wheel, Equinox, Man-Bull, and Schizoid Man.

While Tombstone is in prison and in need of a heart bypass, Hypno-Hustler is among the inmates who he hires to protect him.

During the "Origin of the Species" storyline, Hypno-Hustler comes into a police station wanting help, as Spider-Man is on a rampage against various villains following the kidnapping of Menace's child.

After Tinkerer repairs his costume, Hypno-Hustler tries to escape from prison, only to be defeated by Deadpool and Spider-Man.

During the "Hunted" storyline, Hypno-Hustler appears as a patron at the Pop-Up with No Name.
