A New Enemy

Robin, Starfire, Cyborg, and Beast Boy watched from the doorway as the workers bustled about recreating the Titan's new living room and kitchen. The ten workers had already been working for five hours and the room was almost complete.

"Marvelous!" Starfire exclaimed as she looked around the almost finished room.

"They're the fastest workers I've ever seen," Cyborg added.

"Bruce only hires the best," Robin told them proudly. "Quick and efficient."

"Good cuz I can't wait to kick Cyborg's can once the video game system is set up," Beast Boy proclaimed.

"We'll see about that," Cyborg responded.

Just then the Titans alarm went off.

"It's about time," BB said. "I was going nuts from boredom."

"There's trouble in town. Theft in a high security building," Robin read from the communicator. "I'll go tell Raven that we can handle this. She still should rest up."

Raven woke up from her sleep as the alarm in Titans Tower went off. She rubbed her eyes and tried to wake her dulled mind up. A knock at the door startled Raven back into awareness and she lifted the spell she had placed as Robin opened the door.

"Stay here," Robin said as he stuck his head through the doorway. "It's only a theft. Me and the rest of the Titans can handle it."

Raven was about to protest but Robin silenced her.

"Stay, Raven. You still aren't strong enough," he told her sternly. "You'd be more of a nuisance to us if you came in your weakened condition."

Raven nodded and Robin flashed her an encouraging smile before shutting her door and leaving. She knew Robin was right but she still couldn't help but curse herself for her weakened state and not being able to do a single thing about it.

Robin rode on his R-cycle while Cyborg drove Starfire and BB in his T-car. They were speeding along the streets, narrowly avoiding traffic as they made their way towards the site of the theft. Both slammed on their brakes as they stopped in front of the building. All of them immediately got out of the car and ran inside. It was dark save for the few emergency lamps that lit the halls. Unconscious guards littered the floor as they made their way towards the security vault.

"Keep your guards up," whispered Robin as they silently made their way down the hall.

They were nearing the entrance to the vault. As they got closer they were able to make out the huge blasted hole in the wall where the door should have been. Inside the vault it was completely dark only punctuated by Star's glowing green hands.

"Let me check it out," Cyborg said as they stood in the doorway. He ran his scans over the room to check for any heat signatures or anything abnormal but found nothing. "My scanners aren't picking up any life forms, must mean that it's a robot or something."

"We'll just have to find out," was Robin's reply as he threw ten light disks at the ceiling. Each landed with a thud as they stuck into the ceiling and then suddenly light flooded the room. Standing by the far wall a lone figure clothed in black stood, typing furiously on the main computer's keyboard with mechanical precision.

"Titans go!" Robin yelled. They ran forward preparing to attack the thief. But the thief quickly turned around to confront them while slipping a data chip into its pocket. "Are you another one of Slade's robots?" Robin asked as the Titans stood poised and ready to attack.

The robot-thief didn't answer, instead it moved swiftly towards Robin to deliver him a blow. Robin threw an ice birdarang but the intruder merely dodged and punched him in the chest. Robin was able to put up his arms to block it but he still was sent sprawling backwards.

"Robin!" Starfire cried out. She threw green star-bolts at the thief as it prepared to attack Robin again. The robot merely did a back flip to avoid the attack and turned around to find Beast Boy charging as a rhino towards it. Almost casually the robot pulled a small vial from out of its utility belt. At the last moment the robot threw it at Beast Boy's eyes before quickly dodging out of the way. Whatever had been in the vial exploded as it hit Beast Boy's face.

BB let out a scream of pain as he transformed back to normal so he could rub his eyes. "My eyes! My eyes!" Beast Boy screamed hysterically, falling to his knees with his face buried in his hands. "It burns! I've gone blind!"

"Star go see what's wrong with Beast Boy," Robin commanded her as both he and Cyborg dodged the bomb pellets that the robot was throwing at them. Suddenly the bombardment stopped and the robot was running towards them with fists raised.

"Oh, no you don't!" Cyborg yelled as his arm turned into a sonic cannon and he shot a fire straight at the robot. "Boo ya!" Cyborg stopped as the dust from the blast began to clear. "What where'd it- ugh."

The robot had leaped into the air at just the right moment, dodging the blast and using its foot to kick Cyborg right in the face. Cyborg went flying right into an unsuspecting Starfire, who had been kneeling next to BB and trying to soothe him. Together they were sent crashing into the far wall and they slumped against it, unconscious for the moment.

The robot then turned its attention towards Robin and once again threw a series of mini bombs which he narrowly avoided. He swiftly dodged them and made his way towards the robot. Taking out his titanium pole, he swung it with all his might at the robot's head. Robin was surprised that instead of dodging, it raised its arm to block the blow that would have shattered anyone else's arm.

This is no ordinary robot, Robin thought as he tried to find a hole in the robot's defenses. Not even Slade's robots were this tough. Its actions are way too fast and calculated. Perhaps Slade didn't make this one, but if not Slade, then who?

Robin continued his swift barrage of his attacks, blocking with the pole when he needed to. But the damn robot was just too fast. It nimbly stepped through his attack and defense and gave him a blow to the stomach that made him gasp in pain as all his breath was knocked out of him. The robot turned towards the door but Robin quickly jumped in front of it.

"You're not going anywhere."

The robot swung at him again and Robin was barely able to dodge the blow. He knew he couldn't continue to fight like this. He needed help and badly, but Starfire and Cyborg were still unconscious and BB was too busy crying out in hysteria to help. Robin desperately wished that Raven could have come. She was an important asset to the team and without her…well, this happened.

One fierce kick and Robin was knocked against the back wall. He could only watch as the robot escaped from the vault.

"Dammit!" Robin cursed as he clambered back onto his feet. His side hurt like hell and Robin had a feeling that one of his ribs may have been broken. Ignoring his pain he strode to where Star and Cy were and took out a small flask from his utility belt. He poured a bit of liquid into each of their mouths and waited. Suddenly they both blinked open their eyes and began to cough furiously.

"Ugh. What the hell was that stuff?" Cyborg asked incredulously as he spat to the side trying to rid the foul taste out of his mouth.

"Just a revival potion that Raven gave me," Robin replied.

"That tasted worse than bandecrawadium exeltorgs," Starfire agreed.

"What happened to that robot?" Cyborg asked his eyes scanning the vault.

"You caught him, yes?" Starfire asked brightly.

"Sorry Star, but he got away," Robin said casting his eyes down.

"No worries man," Cyborg said almost cheerfully. "At least we know what we're dealing with. Next time we'll be ready."

"Right," Robin agreed.

"Any change with Beast Boy?" Cyborg asked walking over to where Starfire was already kneeling by Beast Boy's side.

"No," Starfire replied sadly, trying to comfort the weeping boy.

"I'd probably go crazy too if something like that ever happened to me," Cyborg whispered quietly.

"Let's get back to the tower and see if we can do anything for him," Robin ordered. Starfire and Cyborg nodded. She lifted Beast Boy up and placed him in the back seat of the car where she clambered in next to him. Robin climbed onto his R-cycle and the two vehicles made their way towards Titans Tower.
