Whirlwind is a mutant with the ability to create super speed rotation and a supervillain in the Marvel Comics universe. He has also joined forces with evil organizations such as the Thunderbolts, the Lethal Legion and the Masters of Evil. Whirlwind is an enemy of the Avengers, Ant-Man, Wasp, Captain America, West Coast Avengers, and Iron Man.
David Cannon was always a bad seed. Born a mutant, David used his powers to bully other children and steal food. As an adult, David used his speed to become a figure skater, while moonlighting as a criminal called the Human Top.
For years, his crimes went unstopped, until Hank Pym (in his Giant-Man identity) and the Wasp caught him. He became their most persistant nemesis, rivaling Egghead in that title. Going underground for awhile, Cannon remerged as Janet Van Dyne's chauffer, "Charles Matthews", using this cover to spy on his enemies. Whirlwind used this alias to gain access to the Avengers Mansion garage, where he broke into the mansion and trapped Pym and the Wasp inside an ant colony Pym was studying, then planted a time bomb nearby. Pym managed to escape however and warn the Avengers about the bomb. Whirlwind fled the mansion, managing to elude the grasp of Quicksilver, also a superhumanly fast mutant.
Masters of Evil II
Whirlwind accepted the invitation of the Crimson Cowl (revealed to be Ultron-5) to join Klaw, the Radioactive Man, and the Melter in the second Masters of Evil. The Masters ambushed and took the Avengers hostage, but the Avengers escaped. All the Masters were apprehended except Ultron and Whirlwind. Whirlwind briefly reunited with Klaw, Melter, and Radioactive Man as the Masters in Rutland, Vermont.
Whirlwind teamed with Batroc and Porcupine on a mission for "The Hood" (actually an LMD of Baron Strucker), and then rejoined with some of the Masters of Evil for a minor skirmish with the Avengers in Vermont. He finally got another chance at revenge upon Pym when Pym was trapped at ant size, but he did not succeed in killing his old enemy.
Whirlwind remained undercover as Janet van Dyne's chauffeur "Charles Matthews" for several years, trying to devise a foolproof scheme to steal the van Dyne fortune. He also tried, though unsuccessful, to initiate a relationship with the already married Janet. Her multiple rejections made him attack the team more, also causing him to begin a strange fixation with her. Whirlwind's chauffeur identity was finally exposed during a battle with Yellowjacket when Whirlwind showed knowledge of Pym's new disruptor gun that only the Avengers and Charles had seen before.
Whirlwind used his know-how to turn a pack of cigarettes into a bomb that blew open a hole in his cell allowing for him to escape and plot revenge against the Avengers once more. The ruckus caused by Whirlwind's escape alerted the Vision to the situation. When Whirlwind attempted to attack the Vision, the android easily defeats him by utilizing his density powers and his solar energy weapons.
Lethal Legion I
After that, Whirlwind restricted himself to group efforts once more. He joined with the Living Laser and the original Power Man to work as Count Nefaria's henchmen, and was sent to jail after a clash with the Avengers. Count Nefaria used the Legion to give himself their powers.
Whirlwind was recruited into a criminal version of the Defenders.
Masters of Evil III
He was freed from jail by Egghead, who wanted Whirlwind to join his Masters of Evil. Somewhat stir crazy from the confinement, Whirlwind disobeyed Egghead and prematurely attacked the Avengers to get revenge on the Wasp, leading the Masters to an early defeat.
He managed to escape, however, and months later, at his high school reunion, encountered Iron Fist and managed to leave the scene unscathed.
Masters of Evil IV
When Baron Helmut Zemo was organizing his Masters of Evil, Whirlwind petitioned to join. But Zemo, perhaps hearing of how he was a deficit to the previous Masters, assigned Whirlwind the task of detaining Captain America, rather than joining in the main force that was going to take over Avengers Mansion. Whirlwind realized the slight, however, and was determined to prove his worth to the group. He contacted the Tinkerer, one of the underworld's major armorers, and had him create some weaponry for Whirlwind to use; whirling wrist-mounted saw blades. Whirlwind then joined forces with the Trapster, who also hoped to better his reputation, and the two set a road trap for Captain America. Unfortunately, Captain America outsmarted them, and they were both taken into custody.
Whirlwind escaped shortly thereafter and traveled to San Francisco to rendezvous with Tiger Shark, who had learned of a valuable piece of technology located there, while he was with the Masters of Evil at Avengers Mansion. Both Tiger Shark and Whirlwind were apprehended by Tigra, Hellcat, and Henry Pym while trying to procure it.
Iron Man and Whirlwind fought in the skies outside Stark Industries. Their fight causes them to crash through the window of Tony Stark's personnel office. A secretarial applicant named Bambi Arbogast rushes in and begins organizing all of the papers that are strewn around during the fight. She distracts Whirlwind by telling him that there is an important telephone call for him. While Whirlwind's head is turned, Iron Man has to opportunity to knock him out. Arbogast's brave assistance lands her the job as Tony Stark's personal secretary.
Daughters of the Dragon
Whirlwind, 8-Ball, Humbug and Freezer Burn skip bail and team up to rob the penthouse apartment of a wealthy publisher, they get more than they bargained for. Daughters of the Dragon; Misty Knight and Colleen Wing were on the case.
Long Way Down
Returning to his life of crime, David was upgraded and employed by Mandarin along other villains of Iron Man in Mandarin's vengeance on the hero. He fought Iron Man in the Wilmington Oil Field and later took part in the battle against War Machine, in which the hero faked his own death to help Tony Stark in a plan to defeat the Mandarin.
Due to the Mandarin implanting a bomb in him as well as in the rest of the villains, Whirlwind decided to help Mandarin's prisoners, Iron Man and Ezekiel Stane when they rebelled against the villain. He, a new Blizzard and the Living Laser attacked the Mandarin's armories. During the assault, Whirlwind's enhancements were damaged, and he couldn't partake in the final showdown against the Mandarin and his Titanomechs.
Following the death of the Mandarin, Whirlwind returned to the usual business of robbing banks along with Blizzard. When the Avengers left Earth in order to battle the Builders, he and Whirlwind were approached by Spymaster, who offered them to join a group of villains of Iron Man who planned to assault the almost-defenseless Stark Tower.
After Blizzard was revealed to be an Inhuman when Black Bolt set off a Terrigen Bomb, Whirlwind supported him in his decision to leave Spymaster, but they were forced into taking part of the assault on Stark Tower. Once there, Spymaster used teleporter discs to teleport some Iron Man Armors to his buyers, but he escaped and left Whirlwind and the rest of his accomplices to be discovered by the heroes which were using the tower as a base. They managed to defeat the heroes, and they were offered to be taken to Spymaster by Titanium Man. When they arrived to a spaceship where Spymaster was, they were ambushed by him and Titanium Man, who revealed himself as Captain Atlas of the Kree, the buyer.
They managed to escape custody and started fighting Spymaster, Titanium Man and the army of Iron Men, controlled by the first. The actual Iron Man arrived to the spaceship, after having tracked down the armors, and helped Whirlwind and his allies defeat the enemies. During the fight, Blizzard used the powers he discovered of being like a human battery to overcharge the armors and deactivate them, but he fainted and fell out of the spaceship's cargo door. A suit Iron Man was controlling rescued him, but in order to let his friends escape, Blizzard froze himself and the suit.
At some point, Whirlwind was caught by S.H.I.E.L.D. and sent to their new secret prison known as Pleasant Hill, were they used Cosmic Cube fragments to transform criminals into model American citizens. Whirlwind was transformed into a teenager known as Scotty, and was good friends with an ice cream vendor named Harold. One day, Scotty came to Harold to tease him about his dance with Sheriff Eva, whom Harold had a crush on. But in that moment, Baron Zemo started an uprising against S.H.I.E.L.D. and the prisoners changed back to their real selves. Whirlwind and the Absorbing Man--"Harold's" real self--went on a rampage in the town. But Elektra arrived to stop them from killing everyone, revealing herself to have been Sheriff Eva. Whirlwind saved Absorbing Man before Elektra could stab him, but he was so shaken by having his life twisted by S.H.I.E.L.D. that he was ready to surrender. But they were both rescued by Absorbing Mans wife Titania and the Hood, who had come to rescue Absorbing Man and took Whirlwind with them. The Hood latter offered both of them to join his Illuminati, which Whirlwind accepted.
Ant-Man Security Solutions
Whirlwind, along with Miss Thing, Beetle (Janice Lincoln), Magician (Guardineer), The Voice and Hijacker, recently joined Ant-Man Security Solutions. However, after Whirlwind helped Ant-Man infiltrate Cross offices, he chose to depart with ill-gotten gains rather than help Ant-Man.
In the Heroes Reborn reality, Whirlwind is featured as well. This version wears a streamlined suit of armor with multiple blades. He was hired by HYDRA to attack Tony Stark. To this end, Whirlwind kidnapped Stark's secretary Pepper Potts and blackmailed Stark to come to the Stark International office on Long Island alone without his "bodyguard" Iron Man (unaware that Stark himself was in reality Iron Man). Going to the office without his Iron Man armor, Tony was more than ready to deal with Whirlwind without his armor. Using various gadgets to defend himself and Pepper, Stark had Whirlwind chase him down to a Stark International Lab. There Tony activated a Kinetic Intake Converter that threatened to destroy Whirlwind if he didn't surrender. Refusing to do so, Whirlwind was engulfed with the converter's energy and killed.
Whirlwind is among the enthralled villains guarding Krona's stronghold. He tries to attack Thor from behind as Thor helps Red Tornado but is shot by Hawkeye.
Old Man Logan
In the pages of Old Man Logan, the elderly Logan awoke on Earth-616 and had a flashback to where Whirlwind, Red Skull, Baron Blood, Count Nefaria, and Spiral were standing over the dead bodies of the superheroes the day when the villains rose and the heroes fell.
Powers and Abilities
David Cannon is a mutant who has the ability to rotate his body lengthwise at superhuman speed. He can spin his body at about 400 revolutions per minute. It’s unclear if his arms or other limbs could spin the exact same amount and carry the same amount affects. When Cannon’s body is completely engulfed in the self-made whirlwind, his body becomes centered focused to where he could still see, hear, and speak. He could also travel any direction when spinning and travel up to 50 miles per hour in a straight line without tiring. Another unique feature of Cannon’s powers is that when he’s spinning, he becomes extremely difficult to physically touch because of his body’s abnormal rotation. Even though Cannon does appear to be human, his physiology isn’t normal because of his body adapting to his abilities. Because of this, the body fluids within Cannon are thick as heavy oil and his organs are more thick and durable than normal human physiology
Cannon later found ways to manipulate his powers to where he could use them for combat. Instead of having his entire body spinning in a whirlwind, Cannon could ride the whirlwind that his body made, leaving his upper body exposed. He also could manipulate his arms into forming small tornadoes that could be used against opponents. After awhile, Cannon managed to manipulate his abilities and reflexes to where he could deflect massive objects, pick up any objects while spinning, quickly change in and out of clothes while spinning, and physically attack a person while spinning.
