Schultz was originally a self-taught engineer and renowned safe cracker who invented a pair of gauntlets capable of producing powerful vibrational shock waves.

As the Shocker, Schultz quickly rose in New York City's criminal underworld and has been employed by various crime lords, which has often put him into conflict with Spider-Man.

After finally being caught and incarcerated for his crimes, he developed a pair of gauntlets designed to shoot air blasts, vibrating at high frequency.

[12] Shocker later joined Egghead's Masters of Evil (with Radioactive Man, Tiger Shark, Moonstone, and Beetle) to incriminate Dr. Henry Pym, then on trial for treason.

The Masters battled the Avengers in this encounter; Shocker was brainwashed and purposely abandoned by Egghead to deliver a false testimony,[13] and subsequently cooperated with the authorities in exonerating the ex-Avenger.

[14] Shocker was later hired by the Nazi war criminal Baron Von Lundt to kill Dominic Fortune, and built the vibro-shock units into his entire uniform to do so.

Previous alliances include Boomerang, the Beetle, Rhino, Leila Davis, Hydro-Man, and Speed Demon (all of which made up the Sinister Syndicate), and the Trapster, Constrictor and Jack O'Lantern.

[20] During one of his team-ups with Doctor Octopus, he participated in a raid on Avengers Mansion, hoping to help conquer it as the heroes were distracted by the events of the Infinity War.

Individuals thwarting Shocker's victories over Spider-Man include security guards, Dominic Fortune, and even a Scourge of the Underworld impostor.

Preparing to kill the resigned Trapster in an alley, he was attacked and rendered unconscious at the last minute by Spider-Man (then disguised under the alias Dusk).

[28] Shocker was terminated as a freelance agent by Hammer Industries and captured by Spider-Man while trying to rob a federal bank alongside Hydro-Man.

[30] Shocker plays a small role in the "Secret War" crossover event where he was among the villains used by Lucia von Bardas to attack New York.

[32] Shocker was among the group of villains that the Punisher attempts to kill at the wake of the recently deceased Stilt-Man that was held at the Bar with No Name.

Although he seems cooperative at first, as soon as he is secured by Spider-Man, he activates a powerful shock in his gauntlets through his belt, causing the main exit to collapse and allowing him to escape.

[38] During the Origin of the Species storyline, Shocker is invited by Doctor Octopus to rejoin the reestablished Sinister Six, where he exchange for securing some specific items.

[41] Shocker was then seen in the Raft due to a popular online vote at Marvel.com[42] and was selected to join the Thunderbolts's new Beta team called the Underbolts where it was revealed that MACH-V has put his name on the list of likely candidates.

", Shocker appears as a member of the latest incarnation of the Sinister Six, consisting of himself, Boomerang, Lady Beetle, Speed Demon, Overdrive, and the Living Brain.

[49] When New York City was covered in the Darkforce dome by the evil Captain America during the "Secret Empire" storyline, Shocker and Scorpia took advantage of this by robbing a bank but was stopped by Rogue.

[54] During the "Gang War" storyline, Shocker is among the villains hired by Hobgoblin to guard his hideout and are attacked by Scorpion, Shift, and Starling.

[56] The Shocker wears a pair of gauntlets he designed with vibro-shock units known as "vibro-smashers" that, when activated by a pump-action thumb trigger, can project a concentrated blast of compressed air that vibrates at an intense frequency.

A lesser known ability of the gauntlets allows Shocker to make incredible leaps, by directing the air blasts toward the ground in front of him.

How fellow villain the Looter was able to once wield one of the gauntlets without wearing a protective costume and suffering injury is unclear, though his super strength and durability were presumably a factor.

His suit now contains a number of built-in shock units, which throw up a protective vibrational field when triggered by accompanying motion detectors.

However, not trusting to share the whole of his secrets (and thus become what he perceives as expendable), he refused Hammer's technicians access to his actual costume, which (at least at the time) likely wasn't providing him with thorough protection from the feedback of the upgraded gauntlets (he cited nosebleeds as a risk he was willing to take).

He was once stricken with chronic anxiety and paranoia (in the Deadly Foes of Spider-Man series) stemming from his fears about being targeted by anti-heroes Scourge and the Punisher (surprisingly, he has survived encounters with both).

In recent stories ("Venomous" and "Senseless Violence"), Shocker has revealed that he is extremely frustrated with his place in life, not wanting to be known as a punching bag for superheroes like Spider-Man.

When temporarily partnered with Hydro-Man, he rebukes Morrie's suggestion that they go kill Spider-Man, being far more interested in more financially lucrative ventures and trying to rebuild a professional reputation.

Shocker managed to evade capture several times before Miss America finally discovered the entrance to his secret lab.

[86][87] This version is an employee of Adrian Toomes' salvaging company before it went out of business following the Department of Damage Control being established and the group turned to crime.

Additionally, Schultz is the second individual to use the Shocker alias after Toomes accidentally kills the first, Jackson Brice (portrayed by Logan Marshall-Green),[88] and wields a modified version of Crossbones' vibro-blast emitting gauntlet.
