I think it would be Roxas, because...Anti-Sora was formed when Sora was still young and new to the keyblades. Roxas has the experence that Anti-Sora doesn't.
A fanfic story I am making about my KH fancharacter on the spot! ^^
Epiloge: Darkness reigns
"Mom! I'm home"
"Why, Mystica. Back so soon?"
"Jason and Monica are out on a date and Jamee is out of town."
"What are you going to do then?"
"Read, of course." Mystica ran to her room. The book she started last night was waiting for her. She couldn't wait to get it done. She glanced at the the desk. Safe and sound. She began to read....
"Mystica! Dinner!"
Mystica glanced up. 7 pm already? And she was almost done too. Sighing she got up from the bed. Something from the window caught her eye. How did the sky get so black? And...she saw some strange creatures on the ground. Mom and Dad were outside trying to keep them from the house. Mystia grabbed her jacket and went outside. Dad was trying to keep the monsters away but one latched onto him. The next thing Mystia saw was horrifing. What looked to be a heart flew out of her father. "Dad!" But he disappeared. What replaced was one of those monsters! Turning around she saw the same thing happen to her mother! Scared, she turned and fleed. She soon noticed that a black and red light was above her. It seemed to suck in everything! She held on to a tree nearby. Her grip started sliping...she had let go. She remembered floating upwards, then nothing more.
