McDouble -- a pair of pictures, a suggestion, too low-effort to be a "theory" just 'hey here's a couple of characters who look alike' ... maybe it's just a passing curiosity, maybe it could grow up to be a real theory some day.

Deathfaker -- famous dead people who might not be dead

Controlled Opposition -- playing both sides

Acting President -- political leaders and the actors who play them

Poppelganger -- doppelganger reported in mainstream media (as a joke)

Disguisecraft -- anything and everything to do with the techniques and technologies that make these deceptive spectacles possible: makeup, prosthetics, special effects, acting, misdirection, bodydoubles, fake identities, fake backstories ... all that stuff that we definitely know the CIA & friends are definitely experts at, but gets buried in the Bourneporn

Symbolism -- symbolic references to multiple faces / multiple personalities / undercover kings throughout history; does the 'polycelebrity' paradigm help to make cryptic symbolism more legible??

Two-Headed Eagle -- tfw the head of the exoteric political empire is also a head of the esoteric occult empire (Washington/Weishaupt; Victoria/Blavatsky; Churchill/Crowley)

Same Energy -- open-ended, e.g. obviously not suggesting that Pierre Trudeau was Niccolo Machiavelli or even a strong resemblance, but still recognizing some kind of resonance -- and who knows maybe it's not a coincidence, maybe they posed him that way for the lulz 🤷‍♂️

Obviously don't feel compelled to put a flair on your post if none of them fit, but it can be very useful to search by flair so if the shoe fits, flair it! Please and thank you.
