Cannonball (Sam Guthrie) is a superhero in the Marvel Universe and has been members of the superhero teams The New Mutants, X-Force, The X-Men and the U.S. Avengers.


Sam Guthrie was a young man who discovered his ability to project himself at high speeds when saving himself and a co-worker from a mine collapse. Sam was recruited into the ten superhero team the New Mutants and took the name Cannonball.


Samuel Zachary Guthrie was born to Lucinda and Thomas Guthrie in the Guthrie Farmhouse in Cumberland County, Kentucky.  Raised with nine other siblings, Sam worked hard to help his family and began working in the mine after his father died from inhaling coal dust.  On his first day, Sam and his father's friend Lewis ended up trapped in a mine collapse and while panicking, he unwittingly activated his mutant power of jet propulsion to save the lives of the miners who were trapped.

This allowed him to be discovered by the evil villain Donald Pierce, who planned to use him in a plot against Professor Charles Xavier, the founder of the superhero team the X-Men. Pierce convinced Sam to battle against Xavier but upon realizing Pierce's true nature, turned against Pierce and sided with Xavier and his students. After the battle, Sam joined Xavier's new class of students, his New Mutants.


Cannonball possesses the ability to bodily generate thermo-chemical energy and release it through his skin. Accompanied by smoke, flame, and condensation, the equal and opposite reaction to this energy release propels his body through the air like a human rocket. Originally, Cannonball was unable to stop the propulsion until his immediate store of energy was depleted or until he hit an object of sufficient mass to stop him. With practice, however, Cannonball can now cut off his propulsive power at will. As a side effect of forming the thermo-chemical energies over the surface of his body, Cannonball is rendered virtually invulnerable while in flight. Accompanying the release of energy is a half-inch thick energy field that channels the explosion and protects his skin from the direct effects of the blast. It also negates momentum and related effects, thereby cushioning his body from any impact up to a half-minute from the depletion of his energy. Cannonball's "blast field" extends to any person or object with which he is in physical contact, and he can extend it further by concentrating to form a protective shield, even while standing still. Cannonball is also able to absorb kinetic energy through the field he generates and use it to either strengthen his field or redirect it as concussive force. Cannonball once recovered from mortal injuries that left him seemingly dead. It has been theorized that Cannonball's recovery was an indication that he was an External, one of a group of immortal mutants. However, since it has subsequently been demonstrated that even Externals can be permanently killed, doubt has been cast on his alleged immortality.
