A member of the super-hero team the
Avengers published by
Marvel Comics.
Dane Whitman is a decendent of the first Black Knight, Sir
Percy of Scandia, an ally of King Arthur. Fighting as Arthur's
ally, Sir Percy was given his ebony sword, forged from a fallen
meteorite by Merlin. Sir Percy was eventually killed by
Arthur's son, Mordred.
Dane's uncle, Nathan Garrett, used the name the Black Knight
as a costumed identity for his criminal career. He was a foe of
Iron Man and died during one of their battles. His paraphernalia
came into the possession of his nephew, who decided to use the
identity of the Black Knight to make up for his uncle's misdeeds.
Dane rescued the Avengers from Kang and was granted membership
to the team. Instead, the Black Knight chose to be a reserve member
as he was currently living at his ancestral estate, Garrett Castle.
Later, the Black Knight was transported to the past by the Enchantress
where he inhabited the body of his ancestor, Eobar Garringtonb, during
the time of the Crusades. The Black Knight fought for King
Richard until Garrington's body was killed, sending Whitman back to the present.
The Black Knight became a full member of the Avengers for a time, but
succumbed to the the curse of his ebony blade, which turned him to stone. He
later was restored, and abandoned the blade, fearing it to be
to dangerous.
He served as a member of the Avengers again for a time and eventually,
left Earth with the Eternal Sersi for exile in another dimension. He was
eventually brought back to Earth. He was contacted by the Lady of the Lake and
told that he was the champion of Avalon. He was given by her a magical winged
steed and weapons.
The Black Knight has also been a member of Heroes for Hire.
