Sodom's Beast/Draco, is an Alter Ego-class Servant summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order Arcade. She later manifests in the Beast-class in Fate/Grand Order.

Nero Draco is the juvenile form of Beast VI/S, reincarnated as an Alter Ego. While Beast Ⅵ has no particular desire to bloom a second time, she has remained behind in order to witness with her own eyes the fate of the humans who overthrew her (whether it be ruin, or glory). It appears as though she has a strong sense of responsibility.
