Dark Mind
Dark Mind is the final boss of Kirby and the Amazing Mirror. He first appears as a large, cloaked figure during the first final boss battle, having two diamond-shaped glowing mirrors floating around him. However, after he is beaten and reappeared 3 times, he comes back as a large orange sphere with a single eye. In this form, he resembles an artificial sun, as his eye has mechanical aspects to it.
In humanoid form, Dark Mind can teleport around the screen and hurl stars of different colors. If Kirby swallows these, he will gain a different ability based on which color star he swallowed. In his true form, Dark Mind can hurl his (still present) two diamond-mirrors around in circles, fly across the screen, and fire a devastating laser from his eye. He also later fires stars once again, while Kirby has to counterattack using the Warp Star.
