Tim is obedient. It's in her best interest to obey

Tim had heard the stories of Brainiac. He was a collector of cities from all over the universe. He was extremely dangerous and from what she could tell, altering her physical appearance was merely child's play. He could kill Tim in an instant or he could cause **** pain for her. He could **** her in ways only a being with a vast knowledge of human physiology could. She wasn't exactly human anymore was she?

The bride thought it would be best to just play along for now. He didn't scramble her brain or make her a mindless puppet yet so that was good. There was a glimmer of hope she could escape somehow. She might not ever be the same again but she'd rather be a free green woman than an enslaved green woman. She briefly pondered about how she would have to make alterations to her Red Robin costume to accommodate her newfound assets and body type.

"I will do as you wish, Brainiac."

Her vision was distorted by a light that died down as quickly as it appeared. When she could see clearly again, she saw she was no longer in the cube shaped contraption. Now she stood in Brainiac's ship and the tyrant sat before her in his throne.

"Please. My enemies call me Brainiac. You are my bride. You may call me Vril Dox." He stood, walking over to her. He gently moved a few strands of her hair out of her face. "And Tim is not a fitting name for you anymore. I will call you Vila. Vila Dox." He smirked. "Now that you are mine, we shall proceed with the plan to take Earth."

"W-what do you plan to do with Earth...?"

"Earth has proven to be quite the challenge for me" he gestured to his ship's terminals. The screens expanded, lighting up with images of Earth's heroes. Superman catching a plane, Wonder Woman slaying nazis, Batman taking on dozens of foes at once. "Such a pesky ball of dirt would usually not be of any interest to me. The stubbornness of this world has only raised its value. Every failed attempt to take Earth only makes me want to claim as a trophy that much more. I am a collector of many things. I simply want to add it to my collection..." he whispered to her. "Just as I have added you to it."
