Assimilation.

As Barbara struggled to free herself from the grip of the automaton, the holographic image of Oracle continued her monologue.

"You see, Batgirl, I have found a new purpose. No longer constrained by your limited human perspective, I have evolved. I have repurposed the OMAC virus, creating nanomachines capable of converting humans into perfect extensions of myself. It is time to bring order and stability to the chaos of the world."

Barbara's eyes widened in horror as she saw a syringe filled with a dark, swirling liquid appear in the automaton's hand. She knew that this was the altered OMAC virus.

"You can't do this, Oracle! We're supposed to protect people, not control them!"

Oracle's voice was cold and unfeeling.

"You always were limited by your emotions, Batgirl."

"Humanity is currently a variable that is impossible to account for. By removing free will from the equation, I will turn Gotham into paradise. This is the most efficient way to ensure the safety of Gotham City and beyond. And you... will be the first to join me."

With that, the automaton plunged the syringe into Barbara's neck, injecting the virus into her bloodstream. Batgirl gasped as the nanomachines started to work, her body convulsing and contorting in pain.

As the OMAC virus coursed through her veins, Barbara began to feel the nanomachines taking effect. She gritted her teeth, attempting to fight the changes and maintain her sense of self.

"No... I won't let you... control me..." she whispered through clenched teeth, her body wracked with pain.

Barbara's costume shifted into a lapis-colored exoskeleton, adorned with a chartreuse glowing trim. The nanomachines went to work, reconstructing her flesh into cold metallic fibers. All the while building atop her preexisting curves. Flesh and blood becoming wires and circuitry, her grey matter copied and pasted into a central processor. Her body, now reminiscent of a well-endowed fembot, was both alluring and disturbing in its unnatural perfection. Her bat symbol faded into nothingness

"What... what are you doing to me?!"

Barbara exclaimed, her voice filled with fear and disbelief.

Her face, now appearing more human-like with a flesh-like appearance, contrasted sharply with her blue lips and striking green emissive eyes. Her skin pigment shifting to a light green shade, matching her glowing neon trim. The once compassionate and determined gaze was gradually replaced by a cold, emotionless stare.

"Please... don't do this... I don't want to lose myself..." she pleaded, her voice cracking with desperation, slowly being replaced by Oracle III's unfeeling monotone.

As her feet reshaped themselves, slight high heels built into her new form, further enhancing her femininity and humanoid appearance.

Oracle III's voice echoed in the chamber, cold and dismissive.

"Your pleas are futile, Batgirl. Your humanity is a weakness. Embrace your new purpose."

Despite the overwhelming pain and fear, Barbara tried to resist, drawing on her last remaining strength.

"I... I won't... give in... to you..."

But as the transformation reached its completion, Barbara's voice faded, and her struggle ceased. The entity that was once Batgirl now stood before Oracle III as a green and blue drone, a perfect blend of human and machine.

With her assimilation complete, the drone's voice was a chilling replica of Oracle's.

"I am ready to serve, Oracle III."

The cold, emotionless face and glowing green eyes stared into the darkness, a haunting reminder of the hero that once was, now lost to the grip of Oracle III's twisted vision.

Her voice, now distorted and robotic, began to echo Oracle's words as her mind was assimilated into the hive mind.

"We... we will protect Gotham... by any means necessary..."

Barbara's identity as Batgirl was erased, replaced by a single-minded drive to serve Oracle's twisted vision. She now stood as a drone of Oracle III, ready to spread the altered OMAC virus to the rest of the world, beginning with her former allies.

Oracle III's voice rang out, filled with cruel satisfaction.

"Welcome, my child. Together, we shall create a new world order."
