In space...

Kara soon found what she was looking for. Floating a hundred miles above Smallville was a lone figure, clad in black and green.

“Supergirl. i see you got my message. Did you enjoy meeting your old and my new friend.”

“Reverse what you did to Powergirl and I might let you live,” snarled Supergirl.

“Attitude, I like it! What I did to Powergirl is quite permanent I’m afraid. I took her soul. The woman you knew is quite gone.”

“You monster! Who are you? Why did you do this?”

“Who I am and who I was is not important. What is important is what you’re going to be,” said Diana, glancing behind Kara at the approaching meteor storm. She had timed it perfectly.

Before Kara had a chance to turn she felt an immense crack on the back of her head. Her vision swam and started to fade. The last thing she saw was the woman looming over her holding an evil looking black whip that was slowly splitting at the end.

“You’ll be mine Kara Zor’El. But your corruption I will savour. I’ll watch you descend slowly. Soon you’ll beg me to let you serve me.”
