Dusclops

“DUSCLOPS’s body is completely hollow - there is nothing at all inside. It is said that its body is like a black hole. This POKéMON will absorb anything into its body, but nothing will ever come back out.”

— Pokémon Ruby

“DUSCLOPS absorbs anything, however large the object may be. This POKéMON hypnotizes its foe by waving its hands in a macabre manner and by bringing its single eye to bear. The hypnotized foe is made to do DUSCLOPS’s bidding.”

— Pokémon Sapphire

“It is thought that its body is hollow with only a spectral ball of fire burning inside. However, no one has been able to confirm this theory as fact.”
