generally not super into shapeshifter characters being revealed to have like a singular True Form. isnt it much more interesting to imagine a creature so fluid and ever-changing that even they cant identify any one body as the "true" self, or simply dont see the need to?
is this you? yes. this one too? yes. but then which one is the real you? define "real" define "you" theyre all me. even the ones that are someone else? especially those.
tip: everything you pretend to becomes a part of what you are and even the facade you wear for the sake of deception reveals a crucial truth.
also: the self is a multi-faceted, ever-shifting thing
