Unfortunately, for Aster she quickly encounters a cranky superhero, insane costume villains, and a haunted building that wants to kill her.

Author's Note: Yes, this is the reboot of the Criss Cross series I wrote under the Pseudonym of jazzymaymay. Now, as justaddgigi I'm once again for the third time I am rebooting it. I'm older and wiser, and I have a fantastic beta to help me. I actually have this outlined pretty well this time, so hopefully I want get writer's block this time around. I want to thank DarkLadyEris who beta'd my stuff fantastically and was just so enthusiastic about it. Your enthusiasm encouraged me to give this series another go.

I want to let you guys know that although I'm writing about from the perceptive of trans woman, I myself, is in fact a cis woman. I have researched, and talked to real trans women. However, I am human and could have easily made a mistake. If I wrote something incorrectly please let me know. I really wanted to write a bad ass trans woman (which is solely underrepresented in media). Thank you all so much for getting on this ride with me and I hope you enjoy this fic!


"Are you ready for this?" asked Ron Weasley, as he flattened himself against the wall, wand at the ready. Aster Jane Potter silently nodded and raised her own wand. They slowly crept into the abandoned house.

The house was so dark, that Aster could barely see the vague outlines of broken furniture, trash, and various debris that littered the floor. They made their way through the room but there was no one there, Aster made a hand signal that told Ron that they were to check each of the rooms.

He nodded his head, his usual gregarious personality was uncharacteristically grim. Together, they checked each of the downstairs rooms, every little sound of they heard seemed to be amplified jangling their already rattled nerves.

They found nothing. Aster and Ron circled back to the main foyer. They exchanged bewildered looks. This was the address they were given by their informant but no one was there.

There was a loud crash from upstairs and Aster was suddenly running up the stairs, the heel of her boots thumping against the rickety staircase; Ron running behind her she could see his crimson Auror robes flapping behind him, a very real fear like ice over her spine as she followed the noise.

She stopped in front of a slut door and opened it. Aster couldn't move, at that very moment, the blood in her veins turned to ice as she took in the scene. The was so much blood, on the floors, on the ceiling, on every surface in the room. A hysterical part of her mind thought that it reminded of one of Teddy's finger painting experiments. Bile rising up in her throat, almost distantly Aster could hear Ron cursing up a storm.

At the centre of the horrific scene was Amycus Carrow holding a boy by his hair, wide tears staining brown eyes that seemed to hammer into her, pleading and begging for her to help him. His neck was leaking blood from the wide cut that she instantly knew was from a cutting curse.

"Drop the boy, Carrow!" She demanded, gripping her wand in a white-knuckled grip.

"Savior Potter," He snarled, "Always seeming to interrupt my plans."

"Give me the boy," Ron snarled, "And no one would get hurt."

"Avada Kedavra!"

Aster grabbed Ron, and pushed them both on the floor, barely just missing the poison green beam of the deadly spell, she turned and gasped as the boy's body fell onto with a sickening thud. His eyes open and lifeless.

"Always have to play the hero," Carrow taunted and pointed his wand right at her head

"Avada Kedavra!"
