Alter Ego (アルターエゴ, Arutā Ego?), an existence taken out of or separated from a certain Spirit Origin and altered (一つの霊基から摘出、あるいは分離し、変化した存在?), is a non-standard Extra Servant Class comprised of beings that are split off from another. Differing from Alter Servants that are an alternate side or interpretation of a Heroic Spirit, Alter Egos are a phenomenon where "one persona of that Heroic Spirit gains independence as a separate entity." Artoria Pendragon is the same person as Artoria Pendragon Alter, while BB and Passionlip are unique individuals.[1]

The term Alter Ego is not limited to a Servant class, but also the Servant's very state of being. It's possible for an Alter Ego to be of another Servant class while still being an Alter Ego. Both the Sakura Five and the Tamamo Nine are comprised of Alter Egos.
