Disclaimer: I do not own the teen titans.

================================

It was a normal average day for the titans, but that was all going to change.

"Dude I am so beating your butt." Cyborg cheered as he continued to press buttons like mad on his controller.

"Not for long." Said Beast Boy as he pressed buttons at an equally mad rate. Starfire cheered for them both as she watched from behind the couch.

"Beast Boy, your really loosing." Snickered Robin as he watched the game from the kitchen fixing a sandwich.

"Shut it bird brain." Beast Boy mumbled in return.

"What, did you say?" Robin asked in a menacing tone. Beast Boy pretended to ignore him and continued to play his game but the screen went blank. Cyborg had shut it off.

"Hey!" yelled Beast Boy.

"Dude answer the question." Said Cyborg gravely. Beast Boy looked from Cyborg to Robin.

"It'll have to wait, someone's at the door." Said Raven as she rushed into the living room and headed for the front door. As soon as she got there the titans herd a knock. Raven opened the door.

"Sup, you must be Raven." Said an unfamiliar teenage girl. She had shoulder length brown hair with silver highlights. She was wearing a black muscle shirt, black baggy pants, with a blood red sash hanging loosely across her hips. Raven starred into her stunningly silver eyes.

"Who are you and what do you want." Raven asked. The girl smiled.

"My name's..um what was my name again...it's been so long...Oh yah, Zox. I'll meet you on the roof about why I'm here." She said pointing up at the roof and disappeared as the shadows around her feet engulfed her body. Raven turned to the other titans.

"I feel a strange force around her. She's very powerful, we need to be careful." Said Raven.

"How did you know she was here?" asked Cyborg.

"I sensed her presence, it's very dark. I think she's a Forever Fighter."

"A what?" asked Beast Boy. Raven sighed.

"A Forever Fighter, an ancient race of extreme fighters always looking for a new challenge. They wander through the galaxy for another fighter that can match their skills. All of them have silver eyes and streaked hair."

"What does she want?" asked Robin.

"She said to meet her on the roof." She answered. Robin nodded.

"Lets go, be careful."

"What a nice view." Said Zox as she looked over to the city for the top of the tower.

"I'm glad you like it, now tell us why you're here." Demanded Robin from the doorway to the roof as he and the other titans came out.

"Yes, why am I here? I wish to fight you. One against one. If you prove to be a good, worthy, challenge I will let you live, if not you will die protecting your city."

"What do you mean?" asked Robin.

Zox put up her hand and pointed it towards the bay. A small black ball of pure energy formed at her palm. "If at least three of you don't prove to be a challenge this will happen to your city." The ball of energy went flying out into the bay. The titans watched in horror a huge explosion appeared a couple miles off shore. Giant waves erupted and the ground shook from the shock wave. The titans turned to Zox and saw her grinning evilly. "As you can see, I can easily wipe out your city, but you can stop me. Do you accept?"

Ha ha! Review!
