An Evolved Human Alter Ego is the presence of multiple personalities within one mind. One with this ability may be docile and harmless while one ego is present, but powerful and vicious while another ego is present. And perhaps an ego may be invoked based on what type of persona the user thinks the current situation requires (this faculty is called Jungian Shift). It is also possible that each personality comes with a distinct ability or distinct traces (like scent, fingerprints, etc.) within each personality, this is an aspect of Shape Shifting, along with possible transformation based on which personality is active. Sometimes one personality (the normal or dominant personality) has no anomalistic abilities at all.
