Turn him into the Bride of Brainiac

"Per my calculations, a brain as impressive as yours would be best suited to be by my side. It would be in both of our best interests for you to remain capable of independent thought. I will now alter your body to my liking. Please hold still."

"Wait! Hey! Stop!" Tim struggled against the restraints.

"Please do not resist. From what I can ascertain, the transformation can be quite pleasurable if you just relax. It will all be over soon."

"As if!"

The metallic tendrils shredded his Red Robin costume right off of his body. They snaked up his legs, coiling around him and injecting key points on his body with a foreign substance.

"What are you doing to me? What was that?!"

"Since you asked, the nanites I am placing in your blood will allow me to alter your physical appearance down to your very DNA." He explained.

The tendrils released him and he fell to his knees grunting. He felt woozy at first but that feeling was replaced with a high that made him feel like he was on ****. Not that he had ever done **** before. Bruce would kill him. All he could do now was hope that Batman got to him before whatever Brainiac's plan was came to fruition.

His skin changed shade just like that, matching Brainiac's emerald tone. His body was already thin and he wasn't a very big dude to begin with so all he really felt was his muscles rearranging. He lost mass on his shoulders and arms. His hips popped outward to his surprise. What was he doing? Tim thought Brainiac was attempting to make Tim look more like him.

Tim felt his waist get flat yet toned. He ran a hand along his skin, feeling how much smoother and hairless he was. His ass inflated, creating a cushion in between him and the cold metal flooring. His thighs thickened larger than they were before Brainiac started tinkering with his body.

"What are you doing to me..?"

"Though I have integrated my mind into the highest form of advanced technology, I am still at my core a biological being. Therefore I still have a biological need for female companionship. Your mind is impressive relative to your race, I will give you that. However, you are still eons behind my own and I of course am content with being superior. You will be easier to control than a woman from my own race."

"You... you're making me a girl...?"

"Put in laymans terms, yes. Do not fret. You will find your new existence to be quite enjoyable. At my side, you will have access to information previously lightyears out of your species' reach. All your desires will be met a thousand fold and with all this comes a new purpose."

Brainiac continued to edit Tim's DNA like a line of code. He simply switched the "XY" chromosomes to read "XX" and observed the ramifications of his meddling. Tim moaned suddenly, holding a hand over his mouth. His voice raised in pitch to where he didn't recognize it. His dick slipped right inside his pelvis as his vaginal walls formed. His genitals converted nearly instantly into a womb and ovaries. The feeling made Tim bite his lip, both hands going in between his legs as he fell forward.

"Ohhh..." he groaned.

"As I said. Pleasurable."

Brainiac reminded Tim he was watching.

The newly formed woman writhed on the floor as her breasts expanded in between her body and the ground.

"You are coming along nicely." Brainiac added.

Tim's facial structure reconfigured to Brainiac's liking, her hair becoming a light reddish auburn shade.

The tendrils returned, dressing Tim in a tight jumpsuit that clung to her curves rather well. The finishing touch was a small device placed on her forehead and a tendril popping into her neck to insert a small computer chip.

"Your transformation into my bride is complete. You will maintain your freedom of thought but you will be obedient and loyal to me. Disobey me in any way and you will be punished."

Brainiac sounded like he meant that last part.
