Beheeyem are aliens! Or that's what people assume. Elgyem was thought to be an alien because it was first found near a UFO crash, and beheeyem is just the evolution of elgyem. They are normally reclusive Pokémon, only coming out to defend its home, and it does that by flashing the lights on its fingers which can control any creature and erase their memory. You don't ever remember meeting a beheeyem? How interesting...
