A devastating villain that would occasionally hound the Avengers first began when a young David Cannon realized that he had a unique talent to move his body at great speeds. Fascinated as to how he never grew tired or gained sickness, Cannon realized that he was untouchable when spinning in a tight circle. Cannon quickly started on the wrong path with his gained talents by becoming a bully toward other children and then using them for his criminal career as a petty thief. As an adult Cannon found legitimate work as a circus performer, a professional wrestler, and a professional ice skater. However, Cannon’s talents caught the attention of some criminals who specialize in fixing games and employed Cannon to help them with their criminal gains. Cocky and flamboyant over his success, Cannon grew careless over his actions as authorities grew suspicious of his activities which caused him and his criminal partners to be investigated.
Growing overconfident with his success and abilities, Cannon quit his career in fixing games and pursued a criminal career as a costumed thief. Designing a costume and an alias that strongly resembled his abilities, Cannon embarked on a crime spree as the Human Top.
As his main enemy Hank Pym became more involved with the Avengers, Cannon's criminal changed for the better when he redesigned his costumed and renamed himself Whirlwind. As Whirlwind, Cannon became a threat to Hank Pym and the Avengers several times. Eventually, Cannon never made any more major impacts as his remaining career became unsuccessful and he became nothing more than a distrusting lacky who challenged the patience of his partners because of his arrogant, self-centered, egotistical attitude.
