Off the ocean coast of a bustling metropolis lay a tiny island, sitting atop the island sat a large T shaped building. Titan Tower.
It was an ordinary, boring evening for the young inhabitants of the tower. Robin sitting in front of the stereo listening to music, Cyborg and Beast Boy playing video games and making a lot of noise while doing it, Terra watching the two, Starfire wandering about doing this and that, and Raven with her nose deep in a book trying to ignore all the racket.
Suddenly, without warning, the young heroes were violently startled by the thundering boom of what sounded like an object hitting water at enormous speeds. All quickly stopped whatever they where doing and rushed to the closest window in the direction of the alarming sound.
Outside was the apparent source of the noise; two humanoid figures viciously fighting in shallow water, bodies shooting at each other at almost blurring speeds and clashing weapons. It wasn't late, but since it was winter it had grown dark early and it was impossible to determine much about the mysterious combatants, so everyone went as fast as they could down to the exits to get a better look.
After the group had gathered on the beach and Cyborg tuned on his flashlight, they could better see the two individuals, who had brought their fight closer to shore. One, wielding twin katana swords, it was difficult to tell what he was wearing, for he stayed a black silhouette, even in the direct light. The second held a long sword, he was a boy, maybe in his early teens, wearing a long, dark brown trench-coat that was flowing and flapping as he went. Their battle was awe-inspiring! The first, flipping and spinning like he was a ninja doing some raging, deadly dance; and the boy, leaping and shooting in every which way as if a great, invisible giant was hurling him from earth to air to earth like there was absolutly no distinction between the two.
It was like watching two gods, or perhaps demons, fighting some legendary battle; never tiring, never slowing for a second. The Titans dared not intervene, somehow knew to stay away... but how did they know that? It felt as if the thought had been put in their minds from the outside. They realized it was the boy, who was giving them a grim expression, using some kind of telepathy.
Was he protecting them?
The sword wielding boy's attention was then brought back to the fight, dodging and blocking several attacks while the six teenagers at the water's edge wondered the boy's allegiance. Then they caught the attention of the ninja. He cut off from the fight to sprint at blinding speeds straight for them. Unfortunately they had no time to react.
Wait! He seemed to suddenly swerve and veer off his deadly course, barely missing the closely huddled group, throwing up plumes of sand and rocks like bullets as he went past them.
That's when Raven felt it; it felt like a thousand daggers stabbing into her side. She looked down with wide eyes and saw the red blood pouring from the side of her blood-soaked lower torso. "KYYYAAAAAAAAAHHHHHHHH!!!!!!!!" She screamed in pain as she collapsed on her back to the sand, which was now red with her blood. One of the kicked up stones must have hit her side and broken some ribs.
The boy fighter now doubled his pace and leaped at an angle some thirty feet in the air, a second later the ninja had recovered, spun around, and followed suite from the opposite direction. Just as they where about to meet, a short burst of gunfire rang out through the night. As the young boy's feet hit the ground, the ninja's body had gone limp in mid-air. His body flopping and flailing around before it made contact, head first, with a boulder on the beach. It hit with a stomach-churning "SLPACH!!!" and lay lifeless in a crushed, mangled heap on the beach.
In an instant the boy was down next to the wounded Raven, examining her bloody side. "What the hell are you doing!?" yelled Robin, very alarmed that someone who had just fought so maliciously was leaning over his good friend. But then he stopped his protests, the strange boy was gentle, careful, and had a look of pure concern on his face. Was this the same boy he had watched just moments before?
The mysterious boy paid no heed to Robin' words, as if he hadn't heard them at all. He then brought his hands over Raven's injury, which had a disturbing lump that must have been a rib, pushing out, and a large bleeding cut on the fleshy part of her right side. He concentrated, and then, miraculously, the wound slowly began to disappear. He was healing her!
The boy breathed heavily and clenched his teeth; apparently this was a difficult task. In about forty seconds the wound was gone. The astonished Raven sat up, "Th-thank y--". She gasped; when she looked down she had realized that the boy's strain wasn't from effort,
It was from pain.
Exactly where the gash had been on Raven's side there was a growing circle of fresh blood soaking through the boy's shirt! The boy met Raven's gaze with a soft, yet odd, almost laughing smile as he lay down on the sand and slipped into unconsciousness.
