The Black Knight was originally a normal athletic human being with no superhuman powers. While sharing the
gann josin with
Sersi, his strength, speed, and other physical abilities were mildly enhanced. After the
gann josin link was broken, Whitman returned to being a normal human being. As part of his new role as the Pendragon Whitman has gained minor mystical abilities, such as the ability to see through mystical illusions by looking "past the mundane".
Whitman is an excellent swordsman whose skills have allowed him to best

Captain America and
Wolverine. He is also an expert horseman. Whitman started out as a scientist, earning a master's degree in physics while being proficient in a wide array of advanced sciences and technologies, including genetic and mechanical engineering. He maintains a scientific approach and perspective more often than not, despite his ties to the world of magic. He has also demonstrated good leadership skills as leader of both the
Avengers and
Ultraforce. He has strong strategic and tactical skills.
For a short while Dane became a recipient of the Phoenix Force while partaking in its mock trial contest to choose a new vessel for its power. He lost those facilities when he was bested by the Winter Guard's Crimson Widow.
