Dark Mind's Army

Dark Mind's Army are an organization of evil counterparts from the Mirror World and the antagonists of the video game Kirby & the Amazing Mirror. They would go on to reappear as villains in Kirby Triple Deluxe and Team Kirby Clash Deluxe.

Kirby & the Amazing Mirror
Dark Mind and his army attempted to conquer the Mirror World using evil reflections of the people of Dreamland. However, his plan was foiled by Kirby and Meta Knight.

Kirby Triple Deluxe
Despite Dark Mind's destruction, his second-in-command Dark Meta Knight somehow managed to surviv and took control of the Dimension Mirror. The Dimension Mirror somehow found its way into the hands of Queen Sectonia, who stared into it and was corrupted by its power, turning the queen into a brutal tyrant.

In the "Dededetour" mode, after defeating Queen Sectonia DX, Dedede is confronted by an evil mirror clone of himself called Shadow Dedede. Once he has defeated the evil clone, Dedede jumps into the Dimension Mirror to confront Dark Meta Knight. After defeating him, King Dedede shattered the Dimension Mirror and Dark Meta Knight along with it.

Taranza was later corrupted and brainwashed by his mirror clone Dark Taranza as part of a plan to release King D-Mind from the Black Mirror. The plan proved a success though King D-Mind was defeated by Kirby and his teammates soon after.
