Vanessa is the main antagonist in Cytus II, and is one of the 25 playable characters. She was released with the 3.0 update. Currently, Vanessa has 23 songs, and maxes out at Lv. 50.


One of the original "architects" created by mankind. Her unit number is OPCI_2501_V. A girl who wishes for a peaceful, kind future, where humans and architects can coexist without conflict.

Due to her weak core, she is more fragile than her fellow Architects, though she possesses a gentle, kind personality.

Shut down for hundreds of years, she was eventually rediscovered by humans. Forcing her to serve as the core of the virtual internet, her interaction with countless records of human atrocities caused a glitch in her system, producing a new persona bent on eradicating humanity.

Further information about Vanessa: Ivy OS Logs

Vanessa is a kind, caring and empathetic architect who wishes for a world where architects and humans can coexist. As Vanessa is a half awakened architect, she lacks the ability to process negative emotions without syncing to Cytus. In a desperate attempt to become awakened, Vanessa forced herself to become less reliant on Cytus and as a consequence all the negative emotions she feels are left to fester in her core.

Ivy awakens 500 years later to find out the world has greatly changed, though Vanessa still remains immobile. Seeking out a way to awaken her, Ivy uses several methods to try and bring Vanessa back, and ultimately succeeds 2 years later, though that proves to be a great mistake, as Vanessa's core is unstable and all she can feel is immense hatred towards humans, which is her main personality trait. The former tries to stop her, though it's too late by then, and Vanessa unleashes havoc onto humanity by means of the Ender Virus. In a desperate attempt to console Vanessa, Ivy kidnaps Noah to help her transfer Vanessa's original consciousness into an empty architect shell; this fails, and as a result Vanessa becomes the head of a hive mind of Architects, each of which now emulate her burning hatred for humanity.


  • OP_201137_V - Vanessa's core once belonged to the Operator known as OP_201137_V (the protagonist of Cytus). After OP_201137_V chose to engage the Hyperion Protocol, she, alongside the other Operators, were decommissioned and rebuilt as Architects. A glitch in the memory reset procedure allowed Vanessa to retain minimal knowledge of her time as OP_201137_V (the procedure only reset 99.92 / 100%).
  • Ivy - The first awakened Architect that Vanessa befriended, the two viewed each other as sisters. Despite their inseparable inclinations, the events of The Purge ultimately separated them for over 500 years.
  • Ilka - Ilka saved Vanessa from a potential worksite accident and later worked with Ivy to create a temporary Cytus matrix for Vanessa to connect to. Despite actively helping Vanessa numerous times, Ilka harbored resentment towards her as she was the reason Ivy refused to join The Blessed.
  • PAFF - When trapped in her secret garden within the OS space, Vanessa cried out for help and PAFF heard it. After attempting to reach Vanessa, PAFF was forcibly disconnected. Later on, PAFF must decide whether or not to kill the berserk Vanessa.
  • Violette - Following the Decommissioned in the late 400s N.A. and the subsequent founding of A.R.C., Violette recovered Vanessa's unconscious body and used it to create the virtual internet cyTus, used by all humans except those in ConneR's hometown Node 13.
