The Mirrorglaives, according to the index, were an interplanetary invasive species that moved from planet to planet causing mayhem and chaos, because they thrive in a chaotic environment.
Their abilities involve shapeshifting, fear manifestation, and illusions. Their ability to shapeshift into any kind of creature isn't limited to just that creature's physical appearance.
They also mimic their biology, DNA sequence, cells, and finally, their ability, if said creature possessed one.
No one could have suspected that Erin was, in fact, the Mirrorglaive. She...or rather, it, was yet to display any form of unnatural action. It had taken Erin's whole personality, because it had been watching her for days now.
