Beheeyem is a brown alien with an oblong head dented on both sides. A light collar, four chest dots, and red, green, and yellow fingers set it apart.
It evolves from Elgyem. It can erase or rewrite memories, and it is believed to cause Dubwool to vanish.
Under Leon, the Dream Thief, it kidnaps sleeping Pikachu, Axew, and Meowth and replaces them with dolls.
Beheeyem may come from BEM, bug-eyed monster. Its hat and trench coat suggest spies and the Men in Black.
