Y'know, I'm sick of you whining about what you can't do... Let's run like the devil and make Hell freeze over!
~ Speed Demon

Speed Demon is a supervillain in the Marvel Comics universe. He is an enemy of the following heroes: The Avengers, The Defenders, Spider-Man, Wolverine (who was under the alias Patch), Rage and the Falcon (who is the current Captain America at the time). The character first appears as the Whizzer – a member of the team the Squadron Sinister – in the final panel of Avengers #70 (October 1969) and was created by Roy Thomas and Sal Buscema.


James Sanders was a disgruntled chemist tired of his job with the Hudson Pharmaceutical Company of West Caldwell, New Jersey. He was contacted by the Grandmaster and offered superhuman powers in exchange for joining a team that would compete on his behalf. Saunders agreed, and he created a formula based on information given to him by the Grandmaster and that granted him superhuman speed.

The Grandmaster then had him take the identity of the Whizzer, join the Squadron Sinister, and fight the Avengers, who themselves were pawns of the Grandmaster’s opponent, Kang the Conqueror. Although the Squadron was defeated, the Grandmaster kept his word and returned Saunders and the others to Earth with their powers. A few months later, Saunders and the other members of the Squadron Sinister were hired by the alien geographer, Nebulon. Nebulon and the Squadron Sinister tried to melt the polar ice caps, but they were stopped by the Defenders. In the end, Doctor Strange cast a spell of amnesia over the Squadron members, causing them to forget their powers.

Saunders got his job back at Hudson Pharmaceuticals and worked there for a short time until his memory was accidentally restored when the Avengers questioned him about one of the other Squadron members, Doctor Spectrum. Saunders experimented with the original formula that had given him his powers, creating a variant that increased his speed to even greater levels. He took a new name, Speed Demon and began to use his powers in various thefts, most often clashing with Spider-Man.

Later, Speed Demon joined the Sinister Syndicate, led by the Beetle (now the hero MACH-V). During this time, he developed a rivalry with various other members of the team. The team proved short-lived, and Speed Demon rejoined their later incarnation led by the wife of the villain Ringer, which was similarly disbanded shortly after, due as much to the petty in-fighting among its members as their defeat by Spider-Man.

Deciding to branch out, Speed Demon would later participate in an event called the Bloodsport, an annual tournament held in Madripoor showcasing fighters from around the globe. During the first round, He was pitted against Wolverine (as Patch) in a Cylinder Match. Despite his best efforts and the addition to throwing blades into his arsenal, Speed Demon did not fair well. While trying to incapacitate Patch in a vortex of wind, Speed Demon was caught in the neck by one of his own throwing knives as the result of a well aimed throw by Patch. Bleeding profusely, Saunders fell prey to Patch. While the crowd cheered for death, Patch ultimately chose not to kill his wounded opponent. Speed Demon, despite his injuries, survived.

Sometime later, He joined the villains-turned-heroes team the Thunderbolts and, with them, fought Fathom's Five, HYDRA, the Purple Man, and the Avengers. Always contentious and prone to grandstanding, he seemed to serve faithfully with his teammates, but in fact Sanders had been hired by Baron Wolfgang von Strucker to spy on the team for him (although he gave up this role after Hydra was defeated). Sanders had also been committing crimes in his old identity of the Whizzer, funneling it into an account to keep the Thunderbolts operational. He was originally discovered by his teammate, Blizzard, but Speed Demon bullied him into keeping it a secret.

This came to a head when Saunders robbed a division of Richmond Enterprises, which resulted in his former teammate Nighthawk (who owns that company) seeking him out. Before the Thunderbolts could stop Nighthawk, a revived Squadron Sinister also arrived, and they took both Nighthawk and Speed Demon away with them. The Squadron hoped to take over the world in order to better solve the world’s problems, but they were again confronted by the Thunderbolts. Speed Demon hoped to trick the Squadron into thinking he would help them, but he turned on them, helping the Thunderbolts force them to escape. Nevertheless, Songbird ultimately kicked Speed Demon out of the Thunderbolts because of his previous robberies, claiming that what the Thunderbolts needed more were members whose hearts were behind their efforts to reform.

Speed Demon returned to the Squadron Sinister, who preferred to be called Supreme Power, who were again recruited by the Grandmaster. This time, the Grandmaster claimed that the stakes of the game would affect the entire universe, and he hoped to use the Squadron to find the Wellspring of Power, from which he drew upon to grant the Squadron their abilities. (Indeed, Speed Demon’s powers had been noticeably increasing during his time with the Thunderbolts, presumably having something to do with the Wellspring.) The Thunderbolts’ Joystick, investigating the Wellspring on behalf of Baron Helmut Zemo, intercepted Speed Demon’s attempts to track the Wellspring, and the two fought. Joystick surprised Speed Demon by suddenly exhibiting superhuman speeds even greater than his own, and she left him defeated, both his legs broken. Speed Demon was eventually restored when the Wellspring of Power was finally dealt with.

Speed Demon appeared in Brand New Day as one of the villains in the bar. Speed Demon later left the Thunderbolts after it went through a roster change; he then resumed a carrier of villainy. He did a fairly good job of staying away from super-powered foes for a while after that--he was only seen sporadically until joining the Hood's Crime Syndicate. He did so after the attacks on the New Avengers, but before a few of them (including him) battled Mister Negative. The fight ended before anyone died, and Speed Demon remains in the gang making more money then he probably ever did before. However he is no longer a hero. Sanders recently appeared as a member of the Sinister Six, alongside Overdrive, Shocker, Boomerang, the Living Brain (former), and Beetle. After landing "thousands of blows in a fraction of a second," he caused Spider-Man to run away. He was nearly beaten to death by him when he returned. Speed Demon later appears robbing a pawn shop with Man Mountain Marko when they are caught by Rage. After a brief fight, they escape while Rage gets arrested by the Americops. He is later captured by Sam Wilson, the current Captain America, who forced him to confess of his and Marko's involvement in the pawn shop robbery.

Other Versions

The second was Jerry McGee, Tina McGee's husband who went by the name "Speed McGee" and "Speed Demon." A scientist for Genetech where he took the drug Steroid B-19 which gave him superhuman strength, speed, and endurance, he wanted revenge on his wife for leaving him which brought him into conflict with the Flash. The hero managed to help him off the drug and Jerry eventually returned to his estranged wife.

House of M

  • In the House of M reality, Jim Sanders, along with Abner Jenkins, works as a biochemist for Major Josten and General Dugan. He was given a Kree blood sample in hopes of creating a bio-weapon to use against the Kree to stop their alliance with the mutants.

Marvel Zombies

  • The character is infected; he becomes an agent for the zombiefied Kingpin. He is sent with Quicksilver and the Whizzer to pursue Machine Man, who is opposing the zombie efforts. The Whizzer is flattened and the other two are shredded by a taut-wire trap.

In Other Media


  • Speed Demon appears in the Avengers Assemble episode "Dark Avengers," as a member of the Squadron Supreme rather than Squadron Sinister.
