"Bring him back!" Raphael yelled, stomping over to the communication orb and shaking it furiously. "Give him back!"

"Raph..." Mikey murmured, gently placing his hands on the orb and looking into his brother's eyes in concern. "That won't do anything, bro. Put it down," he said gently, using his hands to direct Raph to place the orb back on the worktop.

"We have to tell Master Splinter, guys," Leo stated, turning his back on his brothers and heading out of the lab, fiercely blinking and wiping at his eyes.

"Leonardo," a familiar wise voice spoke up, causing said-turtle to spin around to face his sensei and father. He tilted his head as he looked down at his eldest son, "What is it that troubles you?"

"Sensei..." Leo stuttered, unable to look his master in the eyes. "Donnie's gone."

"Gone?" Splinter's expression hardened a little. "What do you mean 'gone', Leonardo?"

"The Kraang orb, sensei," Leo continued, gesturing his hands in the direction of the lab. "It began to glow and act all weird then one of the Kraang portals opened inside the lab...Donnie fell through it but it closed as soon as Donnie was pulled in, almost as if-"

"As if something from the other side of the portal needed Donatello specifically?" Splinter rhetorically asked, finishing what Leo was saying to him. Leo simply nodded in response to this, causing Splinter to frown a little and then walk toward the lab. "Come along, Leonardo. We must hurry."

There was a bright flash and Donatello found himself hurtling through the air and crashing headfirst into a pile of broken wood and bricks. He groaned as he sat up, rubbing smudges of dust and ash off of his arms and plastron while taking note of his surroundings. His eyes widened a little as he noticed that he was stood in one of the streets of New York...But it didn't look like the New York he lived in; this city was bleak and empty and the sky was a dirty-shade of brown and red. All he could smell was smoke and the steam of rusted engines, the silence of the city scared him a little as he stood up, using his staff as support as he got to his feet.

"What happened here?" Donnie asked himself as he began to walk toward the huge buildings in front of him. As he placed his staff back into the harness strap on his shell, the sound of sirens filled the entire area as several armed-cars sped towards where Donatello was stood.

As the vehicles screeched to a halt in front of him, Donnie turned to run in the opposite direction but was stopped when a large, bright and blinding light covered him, causing him to shield his eyes. The spotlight came from a helicopter hovering above the situation, after locating the turtle, the helicopter began to land.

"Don't move!" several armed soldiers screamed, running out and aiming their guns at Donnie, who was understandably, frozen in fear. Before any of the soldiers could react, a long, thick chain flew out of nowhere and wrapped around one of the soldiers, who dropped his weapon, sending it skidding towards Donnie.

Whatever or whoever was controlling the chain suddenly yanked the soldier forward and threw him into the other soldiers. The light was taken off of Donatello as it located another figure that looked like a taller and older version of the younger turtle. The figure suddenly ran out of the shadows and quickly snatched up the gun and shot at the helicopter, several of the bullets hitting the propellers which eventually caused it to crash into the vehicles underneath it.

"Quick!" the figure grunted, grabbing Donnie's arm and pulling him down behind a small, half-destroyed wall. Before Donnie could react or speak, a massive explosion shook the ground they sat on and filled the sky with black smoke and flames. As the figure stood into the light of the flames, Donnie gasped.

Stood above him was an older turtle wearing a belt with numerous gadgets shoved into the pockets. This turtle was missing part of his left arm and Donnie immediately recognised the turtle due to the orange bandana that covered the entire top of his head. "Mikey?" Donnie gasped. "Is that you?"

"Heh," Mikey responded, smirking at Donnie. "Sure, it's me," he continued gruffly, helping Donnie up from the ground. "Don't look so shocked," Mikey said, watching as Donnie looked over at the huge fire in the distance. "Stuff like this happens all of the time."

"Wha-What?" Donnie stammered as Mikey began to lead him away from the city. "Are you serious? Mikey, what's going on?"

"If what happened back there wasn't enough for you to understand then I have no idea on how to answer that," older Mikey huffed, his gaze softened a little as he glanced at Donnie. "I...I've got to get you someplace safe," he decided. "We're in trouble if the Foot see us."

"The Foot?" Donnie squeaked. "You still deal with them? Even now?"

"Oh yeah," Mikey replied. "Seeing as Shredder took over the city, times have gotten a lot tougher and more dangerous. We have to move now, so follow me."

Donnie complied with the older version of Mikey. He couldn't help but feel sad every time that he looked in the turtle's direction. Where was the fun-loving, playful and cute little brother that he grew up with? This Mikey was the complete opposite, acting grouchy and unhappy with scars all over his body and his arm...Donnie shuddered at the possibilities of what could have happened. But then, there was one thing that reminded Donnie of his little brother; older Mikey's eyes. Yes, they reflected sadness and anger but there was a hidden look of care which showed whenever Mikey looked at Donnie.

Besides, what was that other thing Mikey had said? About Shredder taking over the city? The thought of that was a lot scarier than it sounded. Donatello took a deep breath and continued to follow his brother, planning to ask more questions once they were "someplace safe."
