Alters are corrupted Heroic Spirits, usually turning them into their polar opposite. Alteregos are divided aspects of an original being, in that case : BB.

Alterego is aso a thing only in the Mooncell, and are customized Servants made of various data found in the Mooncell. Technically, they are far more advanced than your typical Servant.

''Hmmm... That's interesting to note that the Servants from Shinjuku are kind of "prototypes" of the Alterego concept : Servants created by mixing-up aspects of various folklore characters until it's stable enough to be a viable Heroic Spirit. Or am I looking too deep into this?''
