The Dark CPUs (ダーク女神/ダークメガミ, Dāku Megami) are five of the antagonists in Megadimension Neptunia VII and the destined enemies of Uzume who has been fighting them alone for a very long time. One of their most notable characteristics is their gigantic size that towers over any other giant monster in the franchise.
They appeared suddenly and began destroying the Zero Dimension. The destruction brought by the Dark CPUs isn't only physical, but also ends up erasing space itself. Therefore, wherever the Dark CPU appear even the land completely disappears into nothingness.
The only way to defeat them is to trap them within a Sharing Field, which Uzume can create with enough share energy, otherwise they are invincible and impossible to fight.
In MegaTagmension Blanc + Neptune VS Zombies, the Dark CPUs (except Dark Orange) can be fought as giant bosses in Multi Mode. Each of the four appear in a 5-star quest.
