Did we ever see Mimic's special unicorn power in MLP & Friends? (Besides being able to . . . get sick because of horseshoes. LOL.) I presume the powers of the horseshoes are their own thing and still still has her own unicorn magic.
Nope.
Mimic's backcard story implies piratical tendencies.
But no magic. Just treasure hunting pieces of eight. Which sort of makes me think she *is* the parrot? Weird
Maybe she's an impressionist...
Re: Ghostbusters - she's almost the right colour, too, to take over the role of Slimer.
