Knights of the Round Table
One of the fictional Fate media franchise's most well known characters, "Saber" aka Artoria Pendragon, is a female character based on King Arthur. In the mobile game Fate/Grand Order, she alongside various other Knights of the Round Table (Lancelot, Gawain, Bedivere, Tristan), as well as Mordred, can be summoned as usable characters. Additionally, in Fate/Grand Order, Sir Galahad is the Heroic Spirit that was summoned into the body of another character in the game, Mash Kyrielight, and therefore is the one to bestow her his powers.
