Avengers: Endgame - Everything You Need To Know About Black Knight
5. He Wields The 'Ebony Blade' - And It Almost Appeared In Doctor Strange
The Black Knight, as with most knights (at least the cool ones), wields a pretty spectacular weapon. However, this isn't just any medieval artefact - it's the Ebony Blade.
The blade was wielded by the original, medieval Black Knight (named Sir Percy of Scandia) back during Stan Lee and Joe Maneely's original run on the character, and it has been passed down to each generation of Black Knight ever since. With Whitman being a great descendant of Sir Percy he is the most recent figure to wield the blade, which is also enchanted and, let's face it, looks really, really cool.
Interesting to note, however, is that the weapon very nearly appeared in 2016's Doctor Strange, as a weapon locked within the armoury of Karmar-Taj, where Strange went to train. For one reason or another the blade was pulled from the script, which may actually hint that Marvel do indeed have plans to use both the weapon and the character of Black Knight in the future.
Ultimately, the studio probably just didn't want to have to force a retcon like they did with the Infinity Gauntlet, which was originally housed in Odin's vault until it was revealed to have been a fake by Hela in Thor: Ragnarok.
