It was a clear night over New York city, allowing the moon to shine brightly down on the rooftops below as a set of Kraang-droids ran across them, with Raph and Casey in pursuit. The Kraang in the front held onto a silver case that glinted in the moonlight.
"Kraang must evade those that pursue Kraang," one of them announced as two of Raph's throwing stars took him out. He landed on the ground with a solid thud, accompanied by the cackling of failing electrical components. The remaining Kraang leapt from the edge of the building and landed on the fire escape of the neighbouring building. The one with the case held it tightly to his chest, being sure not to lose it, as another fired off a few blasts from his alien weapon. They began descending the rusty stairs as Raph followed them over the building's edge. He landed on the fire escape and stopped the Kraang carrying the case, pinning him against the wall with his sai.
"Move it, Casey!" Raph called as he glanced back at his friend, who was still running across the roof.
"You think I'm on a midnight stroll?" Casey retorted, struggling to keep up with the ninja. A grunt escaped his lips as leapt towards the fire escape. He was getting tired, and wasn't able to keep up his strength when lifting off. He managed to grab the outside rail of the fire escape to keep him from falling to the ground. He let out another grunt when his body collided with the bars. The action had jostled the platform and everyone on it, causing it to creak and strain against the weight. The bolts keeping the fire escape attached to the wall snapped out, and the platform began to arch down towards the ground.
"Agh! Hang on!" Casey cried out. It wasn't long before the other bolts came loose and sent the fire escape, along with Raph, Casey and the Kraang, crashing to the cement below. The Kraang recovered instantly, grabbing the silver case and getting back to his feet.
"They're getting away with the Plutoniam," Raph told Casey. "Can't lose 'em." He got up from the wreckage and ran after the Kraang, before being accidentally tripped by Casey, who had tripped himself getting out of the mangled fire escape. "Are you pulling my sai? Let's go!" Raph barked, continuing after the Kraang. He turned out of the alley as Casey lifted up his mask and put his gloved hand to his mouth, mumbling, "I think I lost another tooth." Raph ran down the street, not seeing any Kraang and furious that they had lost them. He passed an alley and quickly back tracked, finding out where all the Kraang had gone.
"What the-?" he breathed as he took in the strange sight before him. He walked into the alley that was now littered with damaged Kraang-droids, all of them missing the actually Kraang that resided inside. Casey nearly ran past the alley and his friend before running to Raph's side, panting heavily once he came to a stop. "Who could've done this?" Raph asked, looking around at the shear amount of damage.
"And it keeps getting worse," Casey told him as he raised his mask and looked over at the opened and empty silver case the Kraang had been carrying.
"They took the plutoniam," Raph moaned.
"What do you think they need it for?" Casey asked.
"No idea," Raph replied, turning to face his friend for a moment. "But whoever it was, packed some serious fire power."
"Let's just hope they're on our side," Casey said.
