King Mystery is a king of darkness and lives up to his name by his form and the minions he keeps. He has the head of a cobra, a feathered body, a lizard's tail, and his hands and feet cannot be identified as to what it belongs to. He also has no eyes except for the hollow sockets that peer through that metallic mask that never seems to leave his face.

Mystery Agent: A faceless minion that seems like an FBI agent. They're a plentiful minion just like the Waddle Dees are for King Dedede. But these minions aren't afraid to use an arsenal of weapons to protect their king, including handguns, bombs, swords, and whatever tool they can get their hands on.

Mystery Shade: A powerful minion for King Mystery that at first appear as a whirling vortex of white and black, but when they sense an intruder they take form and attack. An advantage of these minions is that Kirby would not be able to draw them into his mouth as they anchor themselves to whatever surface they are on.

Shadow Sword: A living sword of darkness. Always quick to attack and ruthless. Kirby can easily obtain the Sword power from these.

Rorshach: A splatter of darkness that shapeshifts at random into things to attack the intruder. They normally appear as an inkblot.
