This is my first teens titans fan fiction. BTW this is min. I hope you enjoy this story.

As the night went on, there was a strange feeling to it like something would happen. And something would something huge.

The night started out normal , but all the sudden the alarm went off. Robin, Starfire, BB and Raven all burst into in. Cyborg was already at the computer getting the coordinates all set.

"What's the matter Cyborg?" Asked Robin.

"A break in at the jewelry store on eight street." Said Cyborg as he tapped away on the computer.

"Titans GO!" Robin called out. All the titans raced out of the tower to the T-Car. As soon as they were in they started down the road. Soon they were at the location though nothing looked out of place. An explosion sent all the titans to the ground. As they try to get to their feet, the ground starts to shake. All the titans are shocked to see Terra, right at that moment.

"TERRA!" Shouts Beast Boy.

"Later Titans." Terra say before she disappears into the smoke and rubble. Back at the ttower, BB starts to cry after seeing Terra after she 'died'.

"Beast Boy, I'm sorry but theres no way that was, Terra." Said Robin as he walked out.

"But it looked like her!" BB cries.

"I'm sorry but there is no way that she survived." Said Cy as tried to calm his sobbing friend.

"Friend, I am also sorry to say that there is no possible way for our friends Terra to survive." Starfire said In a sad tone. BB just cried harder. Robin was in the evidence room even though here was no evidence at the scene. He couldn't believe that an explosion that big left no physical evidence. Also there was something that the others didn't notice, Terra had an accomplice. But who was she? that was the question that sat on his mind. Who is she and how do we stop her?

"Friend Robin, please come join us for some pizza." said Starfire as she walked in to the evidence room.

"Yeah, I'll come join you in a moment." said Robin as Starfire walked out. They all just sat down to eat as the alarm went off. "Titans GO!" shouted Robin

"Where is it Cyborg?" asked Robin.

"The same place." said Cy with a confused look on his face. "Why would they hit there twice?"

"I don't know." Robin said. It took less time to get there this time. As they raced to the site, prepared to duck or run if need be, but there was no explosion. Soon they were inside but the place was up in flames.

"Titans find out if there are people still in here." said Robin. All the sudden terrified screams sounded out of the back area. As they raced to the back room the heat and flames got more intense.

"Where is it?" someone hollered

"I DON'T KNOW!" the another person screamed

"Flames, turn up the heat." said the first person.

"I don't want to. It hurts me and the person. I seriously don't want to do this anymore." said a new voice

"Too bad. Master said to, now do it." the first voice shouted.

"NO!"

"YES!"

"Stop!" Robin called as a scream that sounded different from the first rang through the air. This person sounded to be in total agony.

"Well, well, well. Who do we have here? The miserable titans." said Terra

"Stop Terra. Thats enough damange as it is." said Cyborg

"To bad." said Terra "Come on Flames."

"No, I won't. Plus my names not flames, its Lilly. So why don't you shut up." Shouted Lilly

"Come on! Terra shouted.

"NO!"

"Leave her alone!" BB shouted

"Fine." said Terra as she stalked out but not before she knocked Lilly out. The titans raced over to Lilly. BB stopped by Lilly putting an arm around her. Her eyes shot open and she jumped off of BB.

"Wait!" called Robin as she ran off.

"I'm Sorry." Lilly said

"Wait! Let us help you." said Cyborg, But it was too late. Lilly was gone. As they headed back to Titans tower, robin was deep in thought. He thought there was something familiar about that girl. Like he knew her. Starfire noticed this and was worried.

"Robin? Are you alright friend?" asked Starfire

"Yeah, Yeah I am, Starfire. I'm just thinking." said Robin.

"about what?" asked Raven

"Lilly. She seems familiar." said Robin "Like I might know her."

"How would you know her?" asked BB

"I don't know how I would know her. But it feels like I might. I don't know. She just seems familiar to me." said Robin.

So this is my version of an episode. Basically its a what if. Before Robin became Robin, He was a criminal. A theif. Now when a new foe comes into play, how will robins past be revealed? Will the team accept him back?
