Fictional character biography
Professor Nathan Garrett is the distant direct descendant of Sir Percy, and was born in London, England. He becomes a biologist, research scientist, and university professor. He then became the head of an espionage ring, and was captured by the hero Giant-Man. Garrett fled to Europe, where he found Sir Percy's tomb and the Ebony Blade. Garrett's evil tendencies make him unworthy of wielding the sword, and he is shunned by Sir Percy's ghost. The embittered Garrett then devises an arsenal of medieval weapons that employ modern technology and genetically engineers and creates a winged horse called Aragorn. Calling himself the "Black Knight", Garrett embarks on a career as a professional criminal to spite his ancestor. He battled Giant-Man again and the Wasp but is defeated. Garrett joins the supervillain team known as the Masters of Evil at the request of master villain Baron Heinrich Zemo as the counterpart to Giant-Man, and spreads Adhesive X over the city. However, with the help of jailed villain Paste-Pot Pete, the Avengers find an antidote and the Teen Brigade apply it to the containers, causing it to free the people. The Black Knight is defeated by Thor, as Captain America had decided to catch the Masters of Evil off guard by the Avengers 'switching' foes. He later attacked Stark Industries' plant to lure the hero Iron Man into battle, and was defeated. Alongside the Masters of Evil, he again battled the Avengers and is captured. The Black Knight was among the villains assembled by Doctor Doom to destroy the Fantastic Four. Garrett kidnaps Happy Hogan and falls from his winged horse while trying to kill Iron Man. Mortally wounded, the dying Garrett summons his nephew Dane Whitman to their family estate, reveals his secret identity and repents for his life of crime, with Whitman deciding to adopt the Black Knight identity himself. After his death, Garrett is resurrected by Immortus as a member of the Legion of the Unliving. He battled Hank Pym once more, and "dies" again. His horse is found by Victoria Frankenstein, great-granddaughter of Victor Frankenstein who tried to restore the horse to normal, but instead only mutated further. The horse later became the property of the supervillain Dreadknight.
