Out west, at Bishop's hideout, he was disappointed that Stockman's progress for a cure for the outbreak was a disaster. He was staring at the man roach in a containment unit full of fluid.

"This is unacceptable, Doctor. The progress is lacking. The situation in the city is getting worse, and it's keeping my attention away from my work." Bishop stated furiously.

"Your work? Please!" Stockman said sarcastically. "The original outbreak virus was an unintended side effect of the genetic accelerant I created for you. There are too many variables. I'm testing dozens of retro-viruses." he explained.

Then there was a beeping and a video screen popped up with one of Bishop's associates. "Pardon the interruption, Sir. There's a transmission coming in. We can't trace the signal." he said.

"What kind of signal?" Bishop asked.

"We've never seen anything like it. It's coming in on a dedicated frequency. Sir, they want to talk to you."

"I'll take it in the Comm Room." Bishop replied.

Bishop went to talk to this mysterious caller. He called in his special password and a video screen popped up, with a ghostly figure appearing on it. "Greetings, Agent Bishop."

"How did you get access to this frequency?" Bishop demanded. "How do you know my name?"

"We have been watching you, John Bishop. We know of your abduction by aliens so long ago. We know all." The ghost figure explained.

Bishop was astounded he knew about his secret. Not even the turtles knew about that. "Who are you?" he demanded.

"You watch the skies night after night for your little green men."

"Little grey men, actually." Bishop corrected him.

"Futially gathering all the technology you can to stave off invasion, but right under your nose is everything you need. Information that would set you centuries ahead in your work."

"And I'm to believe you're just going to give me this information?" Bishop asked.

"No, but I can help you get it, for a price." The ghost man proclaimed. "It will be worth it. There is an ancient gemstone encoded with thousands of intricate designs coded with advanced alien technology, and I believe you're familiar with the organization that holds it; they're called the Dark Dragons."

Bishop glanced up at that. He knew they were a branch off of the Foot ninjas that had once worked with the Foot clan.

In New York, down in the lair, Leo watched Raph punching his bag, then he looked back at Leatherhead and Randall, who also looked back at him. They were all hearing the roaring that was coming from the containment unit that held the giant Monster Donatello.

Raph finally stopped attacking the bag to take a break.

Mikey was serving up a tray of breakfast food. He winced at the roaring. He glanced over at Don. Leo was watching him too. They were all worried about him, and what was going to become of him.

As Randall and Leatherhead had been studying Don's results, it was a worrying sign.

Splinter came up and put a hand on Leo's shoulder. "Do not despair, my son. Where there is life, there is hope." He assured his oldest.

"I keep turning to ask Don what we're gonna do, see what brilliant cure he's worked up to fix this, then I remember, that is Don." Leo responded.

"We too wish to consort with Donatello regarding his condition." Leatherhead spoke up.

"He did the majority of the work on the outbreak virus." Randall added.

"Without him, I'm afraid our progress is too slow." LH explained. "Donatello's condition grows worse by the minute. The outbreak strain is reacting violently with the Utrom mutagen in his blood. His cells are breaking down. It's only a matter of time before he is lost forever."

"That's not going to happen!" Leo exclaimed, his hands clenched into fists. "We can't let that happen!" LH, Randall, and Splinter turned to him.

"Every problem has a solution. Every question, an answer. Perhaps we are asking the wrong questions. Donatello told me that this outbreak was artificial, that Agent Bishop created it." Splinter explained.

"And if Bishop created it…" Randall began.

"Maybe, he can uncreate it." Leo finished the sentence.

"Bishop is a dangerous man, Leonardo." Leatherhead warned.

"I know, but we may not have much choice. Especially if Donny's running out of time." Leo assured the croc.

Over in the cage, Monster Don seemed to have tired himself out and he crashed to the floor, looking like he had fallen asleep where he sat.

Mikey approached the cage carefully with the tray of cereal and milk and orange juice. He set the tray down and put a hand on the cage. "Rest easy, Don. We're going to find a way to help you." Then he picked up a remote that opened a hole in the bottom.

Monster Don saw this as an opportunity.

Mikey put the tray into the hole, "It's your favorite, Donny. When you wake up, you can-" he was cut off as Don knocked the tray and food aside. Don roared at Mikey angrily, then he reached out and grabbed his left leg. Mikey screamed in terror.

Mikey tried to free his leg from Don's tight grip on his leg. He tried to keep his balance. "Donny, let go! Raph, help!" he cried to Raph, as he was close by.

"Hang on, bro!" Raph came and grabbed onto him.

The others were alerted to what was happening. "Donny! Let go!" Leo cried out, running over. He leaned on the cage, "Let him go!"

Monster Don glared at Leo, then he heard his name, "Donatello! Hear my voice, my son. Do not let yourself be lost within this form. Hear my voice. You do not want to hurt your brother. Relax, let go." Splinter tried to make a connection to Don's mind. "Let go, my son. That's it."

When Leatherhead and Randall came over as well, Randall added his weight too in pulling on Mikey to get Don to let go. LH went over and pulled the lever that started releasing some gas into the tank.

The gas got Don off guard just enough for him to finally let go of Mikey's leg, making both turtles and the lizard go tussling a few feet.

Just as they were hoping Don would be going to sleep, he came out of it to try to get to them. "He's becoming resistant to the gas. I will have to work on stronger tranquilizers." Leatherhead declared.

Mikey, Raph, and Randall were all rubbing their heads. They all wondered why Mikey had even gotten caught in the first place.

"I just… wanted to give him some food." Mikey explained.

"As much as you want to help him, maybe it's better that you don't feed him, given how dangerous he is." Randall suggested.

Don continued roaring inside the cage.

"That settles it! We're going after Bishop! We'll make him help Don!" Leo exclaimed angrily. He couldn't take this anymore.

"And how exactly are gonna find him?" Raph asked. "Last time I checked, he wasn't exactly listed in the yellow pages."

"I know where he is!" Leatherhead growled. "Remember? He held me for weeks, torturing me! I vowed to catch up with him one day and even the score! But the journey is long. I fear Donatello doesn't have that much time."

Randall was another that understood how dangerous Bishop was too. He had taken some of his torture too. He would love to even the score as well. The turtles and Splinter had as well, if slightly less than Randall and LH had.

Leo rubbed his chin for a moment. "Hmm, maybe Donny can help us with that!" he stated proudly.

They all walked over to the area where Don had parked the new helicopter. Randall had been helping with it too. "This was the last thing Don was working on before…" Their faces all saddened. "Before." Leo finished.

Randall turned on the light switch.

"He completely overhauled Stockman's helicopter. It should get us to where we need to go fast enough." Leo stated. "Leatherhead, go get Donny. Randall, can you make sure all the proper modifications are in place?" he asked Randall.

"Yes, I can do that." Randall replied. He went over to the helicopter to examine it.

By the time Leatherhead had brought the cage with Don in it, Randall declared it was ready. "Everything's up and working perfectly. I even added fuel to it a few days ago. It's full."

"Good. Let's go." Leo ordered.

Mikey called April and told her that they were all going after Bishop to get help for Don. They would be back, but should they need help, that they should be on standby.

April wished them luck and hoped they could get Don cured. She then asked, "Is Randall going too?"

"Yes, he is. We might need his help." Mikey said.

"Be careful." she said.

Leo and Raph got into the pilot and co-pilot seats. LH brought Don on board. Splinter and Randall took seats in the back, as did Mikey. Leatherhead also brought his laptop to monitor Don's condition on it.

Leo brought the copter up out of the water in the pond in the park. It was so awesome the way Don had designed it to come up out of the water. They were off to find the evil Agent Bishop.

Randall was a little uncertain about the flying part about to come. He had never really ridden in one of these before. "Didn't Don say you guys had another helicopter stolen from the Foot a while back?" he asked.

"Yeah, he did. It's in the junkyard where the Professor stays, well, one of them." Mikey replied.

For Randall, so far, the flight seemed pretty smooth. It was just a new sensation he would have to get used to. Ascending hadn't been a problem. He just hoped his stomach could handle it all the way to wherever they were going.

…..

Karai was certain she would find whoever had stolen the Foot Mystics' gemstone and make them pay dearly for stealing it.

Yogami was proud to have stolen it. Now the Mystics were in his power. He was really wanting the Mystics to find the turtles, but most of all, Leonardo.

The Mystics sure hated the younger generations that made them serve them for their own greedy reasons, but then, the Mystics were no different.

Halfway across the US, the copter had to land and get some more fuel put into it. Randall snuck into a gas station and got some. He had watched Don numerous times on how to put fuel into his vehicles and into a gas container. He put some in two containers. Raph was with him, hidden from view, but he helped to get it back to the copter. Then they continued on the way.

Leatherhead kept a constant watch on Don. He kept a watch on his blood pressure and temperature.

They flew the rest of the night. It was five in the morning when they were nearing their destination. Randall had handled the flight pretty well.

…..

In his hideout, Bishop and his commandos saw the helicopter approaching on their radar. It was the one that Stockman had taken awhile back on his misguided trip. They didn't know who it could be, but the agency shut down to make it look abandoned to just see who it was.

…..

"This is it. Groom Lake, Nevada." Leo declared. "Prep for landing." he said to Raph and the others.

Descending was okay, but not nearly as fun as ascending.

"Wait. Groom Lake, as in… Area 51?" Mikey asked fearfully.

"Take it easy, Laughing Boy." Raph stated.

"What's wrong with this area?" Randall asked. The copter was now on the ground.

"We'll show you." Mikey said.

Randall followed the three turtles to a hillside and peaked over it. "Eep! Area 51." Mikey said in fear. The place looked so quiet from out here.

The turtles and Randall ran back to the copter. "This can't be right. Maybe we took a wrong turn, at Albuquerque?"

Randall still didn't get it.

"This is where Bishop's base is located." Leatherhead was sure.

"But Area 51? All those crazy stories. It's the heart of darkness! UFO central! The Nexus of Weirdness!" Mikey exclaimed fearfully, waving his fingers about.

Now Randall was beginning to understand. He had heard a few of the stories before on TV.

"Then you'll fit right in." Raph smiled.

"Weird or not, we're going in there. Straight infiltration! Raph, Mikey, and I will sneak in and get Bishop. Leatherhead, Randall, and Splinter will stay with Don, just in case. Once we have Bishop, we'll convince him to help Don." Leo ordered and explained the goal.

"Leatherhead, Randall, and I can handle that part of the plan. We can be very convincing." Raph put his right fist into his left hand.

"I long to get even with that maniac for what he did to me too." Randall declared, baring his sharp teeth.

"No mistakes. This is a military base. Special Ops, Bishop's turf. Be ready for anything." Leo warned the others.

The three turtles ran over to the fence line to get into the facilities. Their father and two friends waited back at the copter, making sure Don was alright. They would await the signal.

Jumping up and over the fence, Leo sliced the top wires with his katana to make sure his brothers didn't get caught in it. They all landed on the other side without hurting themselves. They just hoped they would stay that way.

"Split up and search the perimeter. Let's see what we're up against." Leo ordered. He and his bros split up.

Leo ran and jumped over another fence, close to a building. He saw the door was open. "Guys!" he called Raph and Mikey to him.

"Okay, you got me. I wasn't expecting this. The place is deserted." Mikey exclaimed in a low voice.

Leo wasn't so sure about that. He gestured for them to follow him inside.

"I'm telling ya, Area 51 is bad news. Aliens check in, but they don't check out." Mikey explained.

"Stifle it, Mikey! I'm warning ya." Raph growled at him. He and Mike followed Leo until he stopped in the middle of the floor. There was a shape in the darkness.

There was a sound, and a light came on, illuminating a man in black. "Bishop!" Leo exclaimed.

Bishop smiled evilly.

The three turtles all took their weapons out, bracing for a fight.

"Welcome, Turtles. I must say, I'm surprised to see you. We don't get a lot of guests here." Bishop said.

"I knew this was too easy!" Raph said lowly. "You think they saw the copter?"

"It's Area 51! They probably have a UFO watching it from space!" Mikey declared.

"Not exactly, Michelangelo. We detected the helicopter as it approached because it's my helicopter. Dr. Stockman took it to New York," Stockman came forward, in a new look, "on his ill-fated trip." Bishop explained.

"Stockman? Still alive?! I thought we were done with you for good!" Raph exclaimed to Stockman.

"Oh, I wish. But Agent Bishop didn't see fit to let me rest in peace." Stockman retorted.

"Enough chit chat. What brings you turtles to my house?" Bishop asked.

"There's been an outbreak in New York, caused by your alien invasion force!" Leo exclaimed.

"I'm… familiar with the situation in New York." Bishop replied.

"Don got infected. He's been transformed into…" Leo closed his eyes sadly. "Into a monster!"

Stockman laughed maniacally. "Oh, that's rich! So much for the smart one."

Bishop peeled his glasses down for a moment. "Perhaps we can be of aid to one another. What if I told you, I could cure your brother?" he stated.

"Why would you help us?" Leo demanded.

"I would help your brother because I require something from you, in exchange." Bishop declared.

"There is no way we should make a deal with this guy." Raph exclaimed angrily.

"Don's in trouble because of Bishop, and he tried to dissect us, remember?!" Mikey shouted at Raph.

The turtles had planned on this. "It may be a deal with the devil, but, what choice do we have?" Leo stated.

Bishop smiled.

The three turtles went back to the copter and told the other three that it was time. Leo flew the copter closer to the building, where there were commandos waiting to bring Donatello into their facilities.

All of Don's family went with him. There was a light being shown on them as they were all escorted inside. Randall had vanished. He didn't want to be seen, but he was there with them.

Don's cage was a platform that floated. He still wasn't happy being caged up, but no one had any intention to let him run loose until he was cured.

They all finished walking inside to where there was a big round, blue ball orb containment unit. Bishop was up on a balcony, overseeing what was going on. Leatherhead looked up and saw him.

"You!" The croc growled. He was ready to attack him, but his friends held him back.

"Easy, Leatherhead." Leo said. "Remember why we're here."

LH growled, but calmed down. Even Randall held still. He didn't like being this close to commandos, after what they had done to him months ago, nearly costing him his life.

"Where did you get this pathetic containment unit? In a junkyard?! Amateurs!" Stockman spoke sarcastically.

Showed what he knew. That cage had managed to keep Don contained without it breaking so far. "Ready the cell for transfer!" Stockman ordered.

Four commandos carried the platform with Don on it closer to the blue cell. The mutants and Randall moved out of the way, but watched every move.

"Doctor, is this transfer necessary?" Bishop asked.

"It is if you want more than his blood pressure and temperature." Stockman replied. "Now open that hunk of junk!" he ordered a commando.

A commando hit some buttons on the cage's keyboard and a purple cage hologram appeared. Then the door to Don's cage opened. He hesitated, then stepped out. It was his first time out since he was first captured.

The commandos tried to move him along with some tazers.

Monster Don didn't like their methods and he fought back. He knocked the first two down, and went to deal with the other two.

Don's family and two friends knew this had been a bad idea.

"Stockman!" Bishop shouted.

"Don, don't." Mikey said.

Don pulled the door off the blue cell like it was glass. He threw it at his family, but it hit Leatherhead in the stomach, making go flying back into a wall, winded.

"Oh, crud." Raph stated.

"This is just great!" Randall decreed.

"Good one, Stockman!" Mikey retorted.

Don then picked up the cage door again and he advanced on Stockman. "No, stop!" Stockman cried out. He got a face full of the door, knocking him away.

The four commandos standing by started shooting. Don put the glass in front of himself as a shield.

"No! No shooting!" Leo demanded, but the humans weren't listening.

Don started attacking the commandos. More tried to subdue him.

"Reinforcements, immediately!" Bishop ordered. Then he jumped down and removed his coat, revealing robotic armor. "Subdue the beast!"

"Don! Hang on!" Raph shouted. He and his bros and Randall flew into action.

Raph grabbed onto Don's right arm, while Mikey grabbed hold of Don's neck, trying to get him to release the commandos.

Randall and Leo kicked and whacked away commandos to keep them from firing at Don. Randall also tripped some with his tail.

"Donatello, please. Be calm, my son." Splinter tried reasoning with his smart son.

But the monster was ready to pound him. Leo jumped in the way and rescued his father just before Don's fists came down on him. "Sorry, Father, but I don't think that was going to work a second time." Leo said. They looked back at Don.

Don was ready to advance on them again when a gas grenade was thrown in his face, blinding him and making him go down.

"NO, BISHOP! DON'T HURT HIM!" Leo yelled at the man.

"If your brother cannot be contained, then he will be put down!" Bishop yelled back. A cannon appeared on his left wrist.

The others couldn't let that happen. Don was on his hands and knees, struggling to breathe for a moment. Raph and Mikey were still down.

"I had hoped we could do business together, but it seems I was wrong." Bishop decreed. He had his cannon aimed on Don's head. Randall, Leo, and Splinter were all angry that this was happening.

Just as Bishop tried to take aim, Leatherhead jumped forward with a roar of his own. He knocked the man away from Don and onto his back. He grabbed Bishop's arm with the guns. "You will not touch my friend! If he must be subdued, then I will do it. Not you, fiend!" LH exclaimed.

Leatherhead then went head to head with Monster Don once again. "Leonardo! Get the tranquilizers!" LH managed to shout to Leo before he and Don rolled down a shaft.

Stockman and Bishop ran toward the shaft. "This is Bishop to commandos! Send in two more squads! Lethal force is authorized!" Bishop ordered on the intercom.

"STOP! Just give me five minutes!" Leo demanded.

"You have two." Bishop said.

"Randall! With me!" Leo ordered and he and the lizard ran out of the building to the copter.

They got the guns full of tranqs that they used on other monsters. They had to hurry.

Don and LH finally came to the bottom of the shaft, and LH struck Don with his tail, sending him through a wall. The croc jumped on his back, but Don proved to be much stronger and he got LH off of him and threw him overhead to a torture lab area.

Leatherhead realized where he was, remembering all the cruel tortures he had endured before. "No! Not this place! Not again!" He looked at the devices in fear. He fell to his knees sadly.

Monster Don them came up, ready to get him again. He stopped by him and he was about to pound his fists down on him when a dart came out of nowhere, piercing him beneath his arm.

Leo had fired the first shot. Randall was beside him, visible. He was back up, but he would let Leo handle it first. They were standing in front of Bishop, Stockman and their commandos.

"Donny, I'm sorry, but this is for your own good." Leo declared.

Don roared and tried to charge him. Leo and Randall started firing their weapons at him. A lot of darts were imbedded all over Don's body, until he got close to them, and he finally teetered and collapsed, unconscious.

Randall and Leo both had hated to fire those darts into Don, but they hadn't had a choice. Leo walked around and placed his hands on Don's shell. "It's going to be okay, Donny." he said.

"He sure was one strong monster." Randall stated.

"He seemed to have gotten a lot stronger than from before." Leo replied.

The humans got Don's body onto another platform with Leatherhead's help and they took him to Stockman's lab and put him in a new undamaged cell, and filled it with the same fluid. The man roach that had infected Don was in the same room, parallel to his cell.

Don's family kept watch while Stockman examined what was going on with the mutated turtle.

"Hmm. Donatello's body seems to be breaking down at a fantastic rate, due to secondary stage mutations caused by the outbreak accelerant. He doesn't have much time. The animal was right." Stockman retorted.

Leatherhead growled, "Leonardo, this is wrong. We can't leave Donatello's fate to these devils. Stockman cannot be trusted, and him!" the croc pointed at the scientists angrily. "If you only knew what he was capable of!"

Bishop crossed his arms proudly of what the croc was saying about him.

LH bared his teeth at him again.

"Leatherhead's right, Leo. Bishop's the enemy! He's the one that caused the outbreak in the first place!" Raph yelled.

"Stockman created the outbreak accelerant on my orders. What you call, the outbreak virus, is an unintended side effect of one of my operations." Bishop proclaimed.

As Randall looked at both specimens in the fluid, he recognized the man roach. Then he looked back at Bishop. He was just as wary as they were.

"Do you have a cure?" Leo demanded.

Bishop looked at the mutants, and then at Stockman, who shook his head no. "Yes." he lied. "But as I said earlier, I need something from you." Bishop said.

Splinter and his family all glared angrily.

"Name it." Randall finally demanded.

"A simple errand really. An item that I require. A relic that may prove useful to my work. I want you to retrieve it for me." Bishop declared.

The mutants and Randall all looked at each other. "From where?" Leo asked.

"New York. In fact, I believe you know the man who currently holds it. His name is… Yogami." Bishop said.

They all gasped at that.
