In the movie, Sam Witwicky encountered the Decepticons Pretender, in the form of a young girl who tries to seduce him while actually trying to incapacitate him.
The Pretender can just imitate any looks or voices…
However in real life… Although there is no such high tech pretender, there is natural pretender… Not to name those organisms such as chameleon, but then also people around…
Not using color, not imitating looks or voices… But then enough for a death blow.
Furthermore, equipped with oxygen tank… If shot upon, will explode and everyone will die within vicinity.
Oxygen is vital to us, oxygen can kill us too…
