In the 2012 universe, Don said "Okay by my calculations he should be on the left." as he and his two brothers made a turned. There, a holding cell on the right. He beamed, hoping that room held the person they were looking for, but he wasn't going to let the happy and excited feeling make him be so hasty with his decision making. As the purple clad turtle peaked through the cell's window with his maroon-colored eyes, a purple impish looking mutant jumped on to window which caused him to scream and jump back with widen eyes.

"Agh, Donnie, I thought you said he'll be in here?" Raph questioned though the mutant in the cell's noises with annoyance and anger in his voice.

"EXCUSE ME FOR BEING STRESSED ABOUT OUR BROTHER WHOSE BEEN MISSING FOR TWO MONTHS!"

"Uh? We got trouble." Mikey said.

Donnie and Raph peered over to where Mikey was staring at with a worried yet kind of shock face.

Thier expressions shifted to more of shock when they saw what it was. A bunch of Krang standing at a distance aiming their guns at them. Turtles scattered as the aliens fired their weapons.

As they evaded the lasers, Donatello heard his brother in red uttered, "I say we should check every door?"

He would have replied back with something sarcastic but didn't, knowing there was no time to do anything else. The trio searched cell after cell.

While the purple headband wearer heard Mikey calling their eldest brother Raph distracting the Krang and their attacks from behind Donnie peaked in into a cell. There he spotted the familiar from of Leo.

"Ha ha, GUYS, I 'VE FOUND HIM!"

"That good Donnie, now bust him out?"

When the turtle in purple turn back to do as Raph asked of him. he stopped and panic crept up. His older brother lied on floor unresponsive, motionless like he was asleep. At that moment he moment, he hoped that Leo was and the Krang tranquilize him or something because the alterative was something much worse. He made haste getting to work on the lock of the cell.

Once he managed to unlock it, the purple clad turtle dashed in there was the doors slide opened.

"Leo?" He called.

As he placed a hand on his brother's shoulder, a groan was heard followed by said brother's eyes opening a bit.

"Donnie?" The elder turtle questioned sounding tired as he appeared.

"Leo?"

"What's going on?"

"We came to rescue you."

"Agh, I feel sick."

The turtle in purple placed a hand to his brother's forehead. his brother didn't seem to run a fever, however if said brother was sick then him being under weighted and dihydride as he looked then it might be worse than getting sick. "Can you stand?"

As Don back away a bit, Leo sat up, but really seem to really struggle doing that. By the time he did he was out of breath.

"We need to get out of here." He said as he went over and placed one of Leo's arms around his own neck.

He then lifted and his brother up, allowing the older turtle to lean on his shoulder somewhat.

"Thanks Donnie."

As the two turtles left the cell, the fighting noise stopped. They peered to see their brothers standing over the leftovers of robot bodies, staring back at them with shock faces.

"Hey guys." Leo uttered in a bit of a tried voice.

"Leo." Mikey called heading to in front of the elder turtles.

"I 'm fine Mikey."

"Eh, for now. I 'm more concern with getting us out of here." Donnie stated.

"Alright Don, find us a way out?" Leo told him.

For quick second the brother in purple gave a small before shifting to a serious one.

"I say we should head this way?" He pointed to the side.

Mikey and Raph went head, but Donnie and Leo followed they ended going slowly, until they stopped when Raph turned head before heading back to them.

"Here?" The turtle in red said as he turned his shell to face his brothers. "I'll carrying him on my shell."

"But Raph-" Leo uttered but was cut off by Donnie.

"No Raph's right Leo. You can't run any faster."

The weaken leader sighed before he stated "Fine, but I don't know how long I could hold on."

"Right."

Raph kneeled down a bit before Leo gotten on. He then lifted his brother's knees and legs, and they were off again.

Leo held on though that task becoming increasingly difficult with each minute that pass. As his eye lids grew heavier, making him want to sleep to escape the stomach pain he felt, he felt Raph running before it halted. The turtle in blue heard lasers being fired followed by Raph moving him to some place. He struggled to keep awake, but his power to do so was fleeing.

After a bit felt his brother laying him down. Where? He didn't know. As the blue head-banded wearer peered over with tired eyes and saw Raph Looking back at him.

"It's alright we got this." His brother in red said putting a hand on his shoulder.

Despite having a bit of doubt on that, he didn't say anything. At that moment, his vision went to black.

Meanwhile, Donnie was inputting codes on the Krang's teleporter ignoring that Mikey was having behind him.

"How's the teleporter Donnie?" He heard Raph's voice sprang up.

"Not good it as though the Krang upgraded the-"

Just then, the turtle in purple ceased when a laser zipped past and over their heads hitting tube that was prompt up against the wall. It cracked but didn't break. That was good.

"I 'm going to work faster." Donnie stated as typed went back to typing.

"While you're doing that, I 'm going to help Mikey."

"Okay." He uttered as he soon heard more fighting noises in the background.

The maroon eyed mutant put in another code and another one, however each new code he did failed. Come on. There has to something to this machine? everyone's counting on him, including Leo.

All of the sudden, he heard something hit something else right before the screen to the teleporter turn blue. The next thing he knew, his vision turned to a blue light before it went to black.
