queen_draco_(fate)
Beast-class servant in Fate/Grand Order Arcade. Initially appears as an aged down version of Nero Claudius (Fate/Extra), but this is considered her immature state. Her mature form is referred to as Beast VI/S, with the S representing Sodom
The immature form of Queen Draco can be obtained as a welfare SSR Alter Ego Servant - as of this writing, the only five-star rarity welfare Servant throughout all of FGO and FGOA. She is later introduced into the mobile game as a summonable Beast-class Servant, making her the first playable Beast in the entire franchise, with a unique summoning animation included. The character card for the Beast class uses her matured Beast VI/S form as the representative.
