Chapter 1

Snow fell over the city of New York on a dark cold winter afternoon. The wind howled quietly as it blew around the first snowflakes of the year. The children smiled as they looked out to the sky and stuck their tongues out trying to catch the white flakes in their mouths. Salt trucks quickly covered the roads in a fine salty layer to keep the roads up to driving standards to keep the 5:00 traffic running smoothly. Everything seemed to be great in the town, just a normal winter afternoon. In a world where Teenage Mutant Ninja Turtles are involved though, when is normal ever normal?

Suddenly, the citizens of New York were sent into panic as large pink swirling triangles started to appear around them and Kraang robots started marching out and shooting their laser guns at anything that moved. Parents scooped up their children and ran in any direction they deemed safe to get away from the danger, many of them taking shelter in buildings and stores if they could. The Kraang invasion had just begun…

((An hour later…on the other side of the city))

Leonardo climbed up onto a dock after being pushed by a Foot-Bot into a large pit below a construction site. He had been ambushed almost 37 agonizing minutes ago by the foot and he certainly didn't expect all of this to happen when he woke up this morning. The bottom of the pit he was thrown into was filled with sewer water that had gotten colder and colder as the temperature dropped. It didn't help that it was below freezing outside either. He stayed lying on his back on the edge of the dock as exhaustion and hypothermia started to consume him. After feeling that his enemies were advancing on him he slowly stood and faced them with a glare in a defensive stance, trying to hide his weakness with strength that he didn't have.

He knew that the Shredder had planned this attack as he glared up at him and his top ninjas, Rahzar, Fishface, and Tiger Claw. They jumped down to stand in the pit with him. He didn't care though. If his brothers were safe, then he'd fight as long as he could hold out to make sure they stayed safe. He had purposely ignored Mikey's calls, not wanting to drag his brothers into a battle he knew they couldn't win.

"Now you may finish him." Shredder commanded his top three soldiers, smiling under his mask.

Leo didn't have time to react as he had been trying to catch his breath in fatigue. He fell back to the dock after an attack from Tiger Claw, leaving a slight redness to his skin. As he slowly stood back to his feet, not giving up, he was harshly kicked back down by Fishface. Before he even got a chance to stand again, Rahzar strikes him back down, leaving small cuts on his arm and neck. Thinking his enemy wasn't getting up, Fishface walked over to him with a smile. He would get to be the one finish him off. His smile melted off his face when the turtle turned his gaze onto him with pure white eyes. He hissed as he tried to back away from the turtle, but Leo easily grabbed his water tube with newfound strength and threw him across the dock, leaving the mutated fish too dizzy to get up after hitting his head too hard in the landing.

The turtle then rolled out of the way as he was attacked by Rahzar from behind. The exhausted blue banded turtle then jumped onto Rahzar's back once he was behind the double mutated dog. Rahzar tried his best to throw the turtle off his back with annoyance. When he finally succeeded he threw Leo at the wall of the pit he had fallen in earlier. Leo quickly reacted though, flipping in the air and kicking off the pipe he had almost hit to propel himself back towards Rahzar, whose eyes widened once he realized that he didn't have time to move out of the way before he was kicked in the face, leaving him partly unconscious close to the edge of the dock.

Leo cried out a battle call as he turned to face Tiger Claw. He ran towards the assassin and rolled to avoid his punch and then he kicked his stomach as he saw the unguarded area. As the mutated Tiger was sent flying back towards the other side of the dock Leo tried to ignore the stabbing pain he suddenly felt in his right knee when he slowly stood up he favored his left foot. Looking at what he had accomplished in his weakened state, he had forgotten that he wasn't quite finished yet. With a flash of lightning, the Shredder now stood behind him. Leo, sensing this tensed up and turned as fast as he could to attempt to defend himself. He was too late. Before he could react, Oroku Saki had brought his gauntlet down upon the turtle, cutting down to the flesh below his plastron. Leo cried out in shock and pain as he slowly fell to the ground and blacked out.

((42 minutes ago,…back at the lair))

Splinter looked over his destroyed home in sadness. He walked to a pile of rubble and bent down to pick up a broken picture of his sons, longing to live in that moment and not in this nightmare. He sighed and closed his eyes. "Don't just stand here like a fool Yoshi." He said to himself as he looked at the picture once more, "Find your family."

He ventured out into the sewers, thinking of places that they could have fled to. He first checked where Donatello kept what he called The Turtle Mech. He didn't find any signs that they had been there though and continued his search above ground at the first manhole he found. Thinking that they might have gone to April's house through all of the destruction, he headed there, carefully staying out of sight of the Kraang and the panic filled state of fear that the civilians were in as they tried to escape the danger.

He finally made it to April's house with relief as he saw Raphael making his way inside. Checking to make sure that no one was around, Splinter pulled the hood on his robe up and quickly ran across the street and into the bottom floor of April's apartment. With a sigh of relief, he took his hood back off and quickly ran up the stairs to the living area and opened the door to find April and Casey were hugging near the door.

"Sensei!" He heard three voices of his sons call out as he was ambushed by hugs. He smiled brightly as he realized it was his sons. He had been correct in assuming they would come here.

"Hello, my sons." Splinter said as he looked down at them. His smile faded when he suddenly realized that Leonardo was missing from the circle of hugs and from the apartment he was in entirely. He looked around the room in confusion, "Where is your brother?" he asked his sons in worry.

Donnie gasped, "Leos still out there!" he said in fear as he looked towards the window.

"What?!" Raph asked in surprise at the new information, not noticing his brother's absence since he had gotten there.

Mikey looked over at him in disappointment, "Long story bro. Basically-"

"There is no time to explain Michelangelo. Where did you last see him?" Splinter asked.

Mikey glanced over at Donnie, "Close to the construction site...or…at least I think that's where we were."

Raph smacked him in the back of the head with a frown, "Mikey! How could you forget?!" He asked as Mikey massaged the place where he had been hit to relieve the pain.

"The construction site isn't far from here!" April suddenly piped up.

"We have to find him quickly and get out of the city. We need to recover before we fight for our home and save the city." Splinter informed them as he led everyone outside.

Mr. O'Neal took the lead when they got outside and led them down the street to an old van, "We can take my old party wagon! From back in my hipster days. Groovy!" he said with a laugh. He was suddenly covered in mutagen. It started to painfully mutate him once more.

"Noo! Not again!" April yelled as Kraang Prime laughed at what it had done and got ready to fire at them again.

"Say goodbye turtles!" it shrieked before spewing more mutagen out onto the street, changing things around them to look like Dimension X.

Casey grabbed April's shoulders as he pushed her to the van that everyone else had already entered, "Come on red! We gotta go!" he exclaimed. April shook out of her shock and jumped into the passenger seat. Casey climbed into the driver's seat and quickly took off towards the construction site, taking a few extra turns to lose their pursuer.

With one last swipe as they got out of its reach, it shrieked out in anger, "Gaaah! Ill get you all!"
