Rider-class Servant first debuted in Fate/Grand Order. Also known as "Blackbeard", the most notorious pirate in history who was known for his purported ruthlessness and his brutal death. He appeared in the Third Singularity "Okeanos".
In-game, Teach is depicted as a pervert and has strong otaku vibes, visible in several quotes in the game (in which he mentions several Visual Novel tropes), his final ascension art, and as well as several memetic references.
