"Supreme Mind Destruction Wave" was an exceptionally special Psychic-type Z-Move.
Its essential effect was to use Psychic-type power to forcibly distort space, dragging opponents into a temporarily created mirrored dimension. There, terrifying Confusion crushed them, while the destructive force of the shattering mirror dimension was inflicted upon their bodies.
