She has a violet color scheme with bright purple hair and possesses no weapon. Unlike the other Dark CPUs, her hands and feet will wisp with purple energy, and she has the ability to fire energy from the palms of her hands. She may perform her special attack without the need of weapons.
For as long as Uzume could remember, the four Dark CPUs have been destroying the Zero Dimension. Because of them, humans have become extinct, leaving Uzume to fight them by herself.
Zero Dimension Neptunia Z: Twilight of the Desperate CPU
Dark Purple's warpath of Destruction
After Neptune and Nepgear fall into the Zero Dimension, they find Uzume which after a brief fight, ask them about where they are. Suddenly Dark Purple descends from the sky, creating a violent shockwave in her wake. Neptune and Nepgear are stunned at the sudden appearance of the giant, while Uzume readies herself for another battle with it. She gets the sisters to leave her alone to fight Dark Purple herself, but Neptune refuses. Nepgear decides to assist as well, leaving Uzume to reluctantly accept their help.
Dark Purple approaches with a horde of monsters near, which the three defeat with ease. Then, Dark Purple ambushes the three while they were caught off-guard, wounding Uzume. Despite being injured, she still wanted to fight the Dark CPU. But Neptune and Nepgear forcefully carry her away from the giant.
The giant seemingly disappears from sight as soon as the three escape back to Uzume's base. Uzume briefs Neptune and Nepgear about the giant and there being three other ones destroying other cities within the Zero Dimension.
After recovering Umio and obtaining a big share crystal from a tribe of friendly Dogoos, Dark Purple makes her return. Briefly shocking Nepgear, Uzume prepares to create a Sharing Field from the Share Crystal in order to trap Dark Purple. However, Arfoire reveals herself and destroys the crystal before she could use it.
There, Arfoire reveals she is in cahoots with the Dark Purple, which she commands to attack everyone in their vicinity. With all hope seemingly lost, Uzume commands Neptune and Nepgear to take the Dogoos and escape. Neptune however still holds onto hope and refuses to run.
The three suddenly feel share energy flow into them, which is supplied by the Dogoos believing in them. Mustering up enough share energy, Neptune and Nepgear regain and transform back into their HDD forms. Uzume follows suit, and manages to trap Dark Purple within a Sharing Field.
Dark Purple manages to put a good fight against the three CPUs, but it was not enough; Dark Purple was defeated and subsequently destroyed within the Sharing Field by the combined efforts of Purple Heart, Purple Sister and Orange Heart.
Many days pass, with Uzume and Nepgear meeting an older Neptune and encountering Arfoire. During a confrontation between the three and Arfoire, she commands a following Croire to give her the power of Tari's CPU. Receiving the power, Arfoire in a fit of hysteria, summons Dark Purple. The Dark CPU quickly obeys Arfoire's commands and attacks the protagonists. Croire alerts Arfoire that Dark Purple would destroy them as well, to which she states that as long as they're destroyed, Arfoire would gladly give her life. Croire then escapes along with the three as Dark Purple begins her rampage.
While Uzume was wounded, older Neptune and Croire went on to gather information. she discovered that during the chaos, Arfoire and Dark Purple merged to become one. Arfoire tripped constantly over her gigantic new vessel, which allowed them to rest and recover in time.
When the time came, Uzume devised a plan for them to take on Dark Purple once more. As the giant traveled with a horde of monsters, they would lie in ambush before Uzume would trap her in a sharing field as she went by, avoiding the other monsters.
The plan seemingly worked at first, but Arfoire was prepared for it. She negated Uzume's first attempt at trapping her, making them seemingly lose all hope. Soon after the friendly creatures came with many share crystals, which Uzume used to try to create another barrier. Arfoire negated the barrier once again.
As they were shocked to see their second attempt fail, Neptune and Histoire contacted them in the nick of time and gave their shares to Uzume. The third attempt at trapping Arfoire finally worked, to which she cried in frustration and desperation. Proclaiming that she would not be put down by the CPUs, Arfoire used the powers of Dark Purple to fight four protagonists in the final fight of the Zero Dimension
Arfoire was eventually defeated. Dark Purple's body dissipated into nothingness, leaving the four protagonists victorious.
Heart Dimension Neptunia H: Trilogy Finale: Into Legend
Capture of the CPUs
After Affimojas' defeat, an enormous hole opened up within Gamindustri's sky. Sensing danger approaching, the CPUs trust their younger sisters to stay behind as they venture into the hole to investigate what is going on. After intercepting a horde of monsters approaching the Hyper Dimension, the CPUs find the familiar face of Uzume greet them.
Neptune introduces Uzume to her CPU friends. Uzume however acts out of character, causing Neptune to become suspicious. Her suspicions were proved correct as Dark Purple was quickly summoned by Uzume. Dark Purple quickly bellows in rage to the original CPUs, causing all of them to jump back in shock and fear. Dark Purple, being commanded by the Uzume they are with, captures the four CPUs and brings them into the other side end of the path.
Nepgear and Uni see this horrifying act of Dark Purple returning and Uzume commanding her, to which Nepgear begs Uzume to return their elder sisters. Uni however makes Nepgear retreat as at the moment they are nowhere ready enough to fight Uzume or Dark Purple. Dark Purple is completed as Kurome takes Neptune's power.
Dark Purple and the other Dark CPUs are re-summoned by Kurome Ankokuboshi. Older Neptune wonders how this is possible as they defeated her already. Kurome says that she has the power of delusion, as long as there is Negative Energy, she can create the Dark CPUs and she still has the CPU's power so they were be complete Dark CPUs.
Neptune says they have the Sharing Field so the Dark CPUs are nothing. Kurome counters with asking the Dark CPUs to fuse. Neptune is surprised by the giant monstrosity. Kurome explains that the new Dark CPUs now has all the powers of the CPUs and she decides to fuse with it to become Dark Orange. The party manages to defeat Dark Orange.
Dark Purple appears as a giant boss enemy in a 5-star quest in Multi Mode. Like the other Dark CPUs in this game, she is silent.
