|“||The one who summoned the invader from another dimension was none other than Taranza, who plotted while hidden in apparent defeat. He has summoned the giant mirror as his final weapon, gazing not only upon its shimmering surface but the dark shadows lurking within...”|

The black mirror is an item in the Kirby series, debuting in Team Kirby Clash Deluxe. It is the origin of Dark Taranza and King D-Mind, and seems to be the reverse counterpart of the Dimension Mirror.
The black mirror resembles a darker, more sinister version of the original Dimension Mirror. Instead of an angelic design with feathery wings, it is adorned with numerous spikes and, with two of the spikes curving upward to resemble demonic horns. The mirror itself appears onyx with some hints of silver, contrasting the Dimension Mirror's golden color scheme.
The origins of the black mirror are unknown. Taranza had somehow obtained the black mirror in an attempt to use its powers to resurrect Queen Sectonia after her death. However, he could not control its dark powers, and as a result, it corrupted him and made him lose his sanity. In this state, he began influencing legions of powerful enemies to besiege the Dream Kingdom.
After feigning his defeat in the Empyrean and summoning Parallel Susie while coming up with a new plot in the shadows, Taranza summons the black mirror as a last resort to use against Team Kirby. Dark Taranza, the embodiment of the darkness in Taranza's heart, emerges from it and does battle with the team; when defeated, Dark Taranza calls up the black mirror as well and summons the King of Darkness, King D-Mind. He destroys Dark Taranza and assaults Team Kirby. He is defeated, but the black mirror returns and summons a stronger form of King D-Mind. The heroes challenge him and defeat him, and, using their magic, they lift his unconscious body back into the black mirror and seal him away in a far-off dimension, before shattering the mirror.
With the mirror shattered, Taranza comes to his senses and becomes a passive member of the village. Peace returns to the Dream Kingdom and Team Kirby vows to suppress any threats that should emerge.
|“||And so, the king of darkness—who sprang from the ugliness of the black mirror—has been sealed in a far-off dimension by Team Kirby. Taranza is now free of the mirror's magic and has returned to normal. Now, at last, peace will return to the Dream Kingdom...”|

|“||The black mirror is gone, and peace is finally, truly restored to the land! You faced so many hardships. I know it wasn't easy... After all of the battles you fought for the people of this kingdom, you have my gratitude, and my respect. Your deeds will surely go down in history. No, they'll become legends! For all you've done, I truly thank you!”|

- The black mirror appears to be the direct opposite of the Dimension Mirror; it has a demonic frame that contrasts the Dimension Mirror's angelic frame, and it behaves similarly to when the Dimension Mirror was corrupted by Dark Mind in that it reflects only bad things rather than granting wishes.
- Whether they are one in the same is unknown. In a Nintendo Dream interview, the black mirror is referred to as the "Distorted Black Dimension Mirror." This may imply that this is the case, although it is more likely that they just share a name.
- Parallel Susie's mech sports the same eye insignia as the one found on King D-Mind's hammer and clothing. This suggests a connection between the two, which could indicate that Parallel Susie has some tie to the black mirror itself, despite being a counterpart from Another Dimension and not the Mirror World like Dark Taranza is.
- According to a Nintendo Dream interview, Parallel Susie (as well as Parallel Landia) was created as a result of Taranza meddling with the black mirror's powers while trying to revive Sectonia, throwing the world out of balance and thus allowing Taranza to bring her forth from Another Dimension. This may explain as to why she has the insignia, even if she is not the same type of counterpart as Dark Taranza.
