To put forth an example, in Zenless Zone Zero, Belle and Wise are commissioned to impersonate a Proxy known as Phaethon. Little do their clients know, they are Phaethon; they just had to dispose of that identity when their account was hacked, and they're now working under a different moniker. As such, they're essentially impersonating their old identity.
Is there a trope for that?
