Fictional character biography
Thomas Maximoff
Thomas and William were twins, with Tommy being the older of the two, Thomas and William supposedly born to Scarlet Witch and Vision; in reality, Scarlet Witch used her reality warping powers to create twin sons, unknowingly, from two of five scattered fragments of the soul of the demon Mephisto that were previously lost to him in an ill-fated encounter with the powerful mutant child Franklin Richards. When the boys' souls were reabsorbed into Mephisto, because of the power Wanda put into the soul fragments, they destroyed him and their souls were reincarnated as Thomas Shepherd, the Young Avenger Speed, and Billy.
Thomas Shepherd
Thomas "Tommy" Shepherd was raised in Springfield, New Jersey, as the only son of Frank and Mary Shepherd, who are divorced.
Wiccan and the other Young Avengers locate him as another teenager with ties to the Avengers using the same program devised by the Vision that Iron Lad used to locate most of the current Young Avengers, their intent being to recruit more super-powered teens who could help them rescue their abducted teammate, Hulkling.
The Young Avengers find Tommy in a high-powered facility in Springfield that Hawkeye (Kate Bishop) initially describes as "just juvie" (juvenile hall), though the facility and its staff are equipped with advanced offensive and defensive technology such as robotic suits and power dampening containment cells.
Vision states that Tommy is being held at the facility, presumably under court order, because he "accidentally" vaporized his school. When they release him from his cell, it is immediately noted that Tommy, a white-haired speedster, bears a striking resemblance to Billy ("twin-like") and Quicksilver, sharing the latter's hair color and similar abilities.
The team encounters the armed officers of the facility. Tommy cynically and cruelly begins attacking the officers and fleeing doctors, stating that he had been locked up for months and that during his time there, he was tested and experimented on with the goal to make him into a living weapon. Hawkeye and Patriot manage to stop him and convince him to join them in rescuing their teammate Hulkling from Kl'rt the Super-Skrull. Little more has been revealed about the facility or Tommy's experiences there prior to his release, nor have they been addressed by the other Young Avengers or Tommy himself.
Tommy joins Billy as they search for the Scarlet Witch through Genosha and Wundagore before finally encountering Master Pandemonium at a former residence of the Scarlet Witch and the Vision. Pandemonium decides not to fight the boys after recognizing Wiccan's magic as being the same as the Scarlet Witch's. Instead, he elaborates on their history concerning Mephisto and the Scarlet Witch and advises them that the history they search for is filled with "darkness and chaos" and that they should embrace who they are in the present.
Powers and abilities
Speed is a mutant with the power to move and accelerate at speeds far beyond those of normal human beings. His physiology is designed to move at high speeds which also grants him superhuman reflexes, agility, and durability. This durability is limited to impact forces, so bullets, energy blasts, and other piercing attacks are capable of harming him. It is also likely that Speed possesses a high amount of superhuman strength in his lower body, allowing him to lift around 1 ton, while his upper body is strengthened to the point where he can lift around 800 lbs. Although his top speed is unknown, he can exceed the speed of sound (about 1,225 km/h, or 761 mph) and resist the effects of friction, reduced oxygen, and kinetic impact while moving at those speeds. In Young Avengers Presents #3 he asserts that he is "Quicksilver fast", shown running from the eastern seaboard of the United States to Genosha, an island off the east coast of Africa, as well as search the entire island for anyone living there in the same amount of time it takes Wiccan to teleport the same distance. This indicates that Speed is fast enough to run across the surface tension of a body of water without sinking. In addition, his mind can operate in an accelerated state, allowing him to read in super speed and remember everything he has seen.
He can also generate hyperkinetic vibrations that accelerate the molecules in matter, causing any solid object he directs his vibrations at to explode. During the Civil War: Young Avengers and Runaways crossover, when both teams invaded the Cube to save their friends, Speed is shown exploding a gun in his hand by using his hyperkinetic vibrations. He is also able to accelerate his molecules (or even those of small groups of people) and vibrate fast enough to pass through solid matter, such as walls.
Reception
Critical reception
Nishid Motwani of Comic Book Resources (CBR) referred to Speed as a "fan favorite character audiences can't help but love," writing, "Speed has spent a lot of time isolated. He was kept in a facility where high-powered individuals are held captive and experimented upon. Despite the things he has gone through, Tommy's personality is still vibrant and he instantly makes fans fall in love with him." Alex Schlesinger of Screen Rant wrote, "Speed sits at a unique intersection where Young Avengers fans feel they know Tommy and have witnessed his growth, and yet have incredibly few stories where he's a central character. Now would be the perfect time to tap Speed to act as the team lead and mentor for the next generation of youthful superheroes. Speed has the charisma, power, legacy, and connections to be an ideal leader, and it would be incredibly helpful for a new team to have a slightly older, more experienced leader who could guide them in their heroics. The hero Speed, son of the Scarlet Witch, has not been utilized enough in Marvel Comics, but hopefully the future will give Tommy the spotlight as the leader of the Young Avengers."
