All of the Knight's abilities come from his technology from Obadiah Stane. He wore a protective suit of armor, rode a mechanical anti-gravity steed, and wielded an energy lance which could pierce Iron Man's armor.

Other Info
Fletcher Heggs was the "Knight" in Obadiah Stane's team of special bodyguards named the Chessmen. (To learn about the above highlighted character and/or team, just click on their names.)

On the Knight's fist mission, Stane instructed him to intercept his business rival Tony Stark's plane on the way to New Mexico and assassinate Stark. With his anti-gravity steed and energy spear, the Knight tried taking down Stark's aircraft as it was en route; however, Tony managed to repair the plane using his Iron Man armor and arrived at his destination safely. (Click on the highlighted name above to learn about Iron Man.)

Later, the Knight made a second attempt to kill Stark at the compound of an Irish terrorist. In fact, in this assassination attempt, the Knight gained the upper hand thanks to his spear easily penetrating Stark’s armor, and came close to killing Stark more than once. However, Iron Man used tricked the Knight into a defensive position, enabling him to take the Knight out with an explosion. The Knight was then arrested and incarcerated.

Soon after the Knight was incarcerated, another one of Stane's Chessmen, the Bishop (Alban Emond), arrived in New Mexico to punish the Knight for his failures. The Bishop broke the Knight out of prison, flew him high into the sky, and then dropped him--letting the Knight fall to his death. (To learn about the Bishop, just click on  his highlighted name above.)

Later, Fletcher Heggs was succeeded by Basil Thorpe who took up the mantle as the "Knight." (Click on the highlighted character's name above to learn more about him.)
There isn't anything there, but here is the Marvel.com bio page of the Knight, http://marvel.com/universe/Knight_%281st_black%29.

In the Marvel One-Shot: All Hail the King, Fletcher Heggs appears as an inmate at Seagate Prison. He is a fan of fellow inmate Trevor Slattery, and acts as his protection from other, more violent prisoners. Also, Heggs frequently asks Slattery to do lines from his performance as the "Mandarin."
