Agents of STRIKE
Real name: David Cannon
Documented extranormal abilities: David is a cyborg, his body augmented by Dr. Paul Ebersol (alias: The Fixer). His cybernetic augmentations include two large, electrically charged blades that vibrate at high frequency to cut through almost any object, and the ability to move at incredibly high speeds. Cannon uses these abilities to generate massive amounts of turbulence and other distortions in the air, spinning at high velocity and while still being able to fight effectively himself.
Why David Cannon decided to undergo cybernetic augmentation at the hands of the Fixer remains a mystery. He’s never been apprehended, and is still at large despite several run-ins with the Avengers and Spider-Man. He works as a mercenary and petty criminal, apparently motivated by repaying a debt to Dr. Ebersol for his cybernetics (Ebersol may also be blackmailing Cannon in some unspecified way, more data is needed).
Prior to his augmentations, David Cannon seemingly had a difficult life. A man who had trouble holding down a job, substance abuse problems, run-ins with the police, little in the way of familial connection, no significant other. It’s entirely possible he struck some kind of Faustian bargain with Ebersol to improve his life. If so, it’s possible SHIELD could make the cyborg a better offer if he was apprehended alive and in more or less one piece.
