Shapeshifter

This is truly a sad tale...She sold her soul long ago. Though always accompanied she will always be alone. For she has no loyalty save one, her youngest. He too will see the shapeshifter when the light comes on. The damage will be irreversible and irreparable. His fate is that of his father. Both are caused by the wickedness that lies within her. The puppet master will rejoice, for she will have no other but him. That was his plan, knowing she could not see more than two steps forward.

Mary is a shapeshifter.

Tom is a shapeshifter.

One day, Mary revealed to Tom that she was an extraterrestrial shapeshifter who had come to Earth several hundred years ago to study humanity.

The shapeshifter Lisa Bowalk, unable to shed the guise of a black panther, had gone onto the plain as a prisoner but was not now to be found among the dead above or the Captured down below.

Like the teller of shapeshifter stories—who conjures a shifting world of perceptions and expectations for his or her audience that is strikingly similar to the worlds created by the shapeshifter for its victims—the cultural practice of imagination...is an inherently shifty enterprise....

“The Jem'Hadar? You fought the Dominion? Ah. The shapeshifters sent many warriors to Sto-vo-kor. I wish I could have seen it.” “No, you do not. There was no honor, just massacres.” “But in the end you were victorious.” “Starfleet is supposed to be about puzzling together the mysteries of life, not fighting wars. I don't want to be a general. I don't, I don't want to send my friends off to die. I just want to be an ensign. If it was good enough for Sito, then it's good enough for me.”

“Oh, no! That house belongs to shapeshifters. [spits]” “Fuck.” “You're kidding me, right?” “Shapeshifters are... extremely freaky.” “They are awful, abhorrent creatures that use the most ancient of sorcery to transform into whatever murderous, all-powerful shape their wicked hearts desire. And now, they have infiltrated our street.” “I have had horrible experiences with shapeshifters in the past. I was once in a relationship with a woman for four years who then transformed into a possum. I stayed with her for six more months, but then I just had to end it.”
