Randall had found a wonderful life here in the human world, but he often wondered really what would happen if he ever tried going back to the monster world. He did miss some aspects of it, like being able to walk around freely on a daily basis. Hiding in secrecy all the time was very irritating a lot of the time when he wanted to go somewhere.

The Shredder had been his friends' most persistent enemy, and they were glad he was now out of the way. And there would probably still be the Foot clan to deal with. Hun was out of the way too thanks to Randall.

Another enemy the mutants had to worry about popping up was Agent Bishop. And he could do far worse, since he was after an army of super soldiers. Randall knew better than to give information about his world to him. The turtles had told him that even though they had banished him, it would be for the better that he never told Bishop anything. He would be capable of destroying the world.

Awhile back, when Bishop had kidnapped Master Splinter, Randall saw first hand how dangerous he was. And having experienced some torture at his hands before, there was no way he was giving him any information, even at the risk of his own life.

…

Back in the Monster World, it had been over a year since Randall Boggs had lived there. His disappearance to many was a mystery, but there were many who didn't miss him one bit, since he had been nothing but the biggest jerk to many.

Mike Wazowski was really glad he was gone most of all.

James P. Sullivan had been glad to punish Randall at the time he had thrown him through that door to protect his human friend, Boo. But it had been a long time now since Randall had been heard from, and Sulley was beginning to feel guilty about what he had done to the lizard. He often wondered if Randall was still alive.

The factory had now changed to Laugh energy instead of Scream. Sulley knew that Randall wouldn't fit in with the new way things were. Randall had never been much of a happy guy, at least that he had seen, and when he was, it was at the wrong things.

Once Mr. Waternoose had been arrested, it had taken about a month to get the factory back up and running because there was no CEO in charge, and the board of directors had to find a new one, and like pronto at the time.

Mike had actually given Sulley the idea of laughs that could power their world, and of course, he remembered during the door chase and when he and Mike had first discovered that a human kid could really power up their electricity with laughing.

Sullivan had talked to the board of directors about that laughter was ten times more powerful than screams. And it would save them from the energy crisis.

The head monsters on the board had been hesitant to try it, but once they gave the go ahead, Sulley was pleased. But he was a little more shocked when they asked him to be the new CEO.

New canisters had had to be made to collect children's laughter because it was powerful. They were much larger than the scream cans had been.

Mike found himself becoming the company's number one comedian. He had always been that way, as well as a good coach. He liked doing this more than just being the assistant, though he was proud of Sulley back when he was doing all the work as a scarer.

It had been over a year since the two friends had secretly banished Randall, and even Randall's former assistant, Fungus was doing a good job in the factory. He was even a comedian himself, and doing a good job of it. He was even happier, he didn't stutter so much when he talked now because he wasn't being threatened all the time.

Sulley had had a depression since he had taken Boo home and her door shredded, but in secret, Mike had been going through wood shreds and putting her door back together and he finally surprised Sulley with the door, and when Sulley put the final piece back in place, the door was now activated once again. This door would be kept as a secret from CDA.

Sulley found himself a lot happier now that he was seeing Boo again, as he had deemed her. But he was still thinking of what he had done to Randall.

Would banishments ever be lifted from the monster world as punishment? Why couldn't they just go to prison, like Waternoose had? Randall should have been in jail, not the human world.

Sulley would have been happy to look for him, but who knows if he was dead or alive by now, and he could have wandered off. But he could be looking for a way back for revenge too. Maybe he was back and just biding time for revenge against them.

Mike feared revenge from Randall should he ever return.

The CDA was on the lookout for Randall too. Waternoose had revealed that he had been part of a conspiracy working with him to take over the city. He wanted Randall to take the blame of punishment even more than him.

If Randall ever returned, he would be arrested, but there would be a hearing for him to see what his fate would be. Talking to witnesses and the lizard himself would determine it, as well as what his testimony was.

…..

Weeks later, after the Shredder's demise, the Foot Elite were stepping up as the new leaders of the Foot and were wanting to rule the city and take down their enemies, including the turtles and their comrades.

The Mob and Purple Dragons were also looting the joint and fighting with the ninjas too. All these baddies were trying to get a hold of the Shredder's empire.

At the lair, the family was seeing it on the news.

Randall saw it on the news too, which meant that he and the turtles would have to be extra super careful about when they went on patrols. But it was easy for Randall to get away from these enemies, as he could easily vanish, but the turtles couldn't, at least not in the physical sense. They could only hide.

The city had been at war once before, but the Shredder had come back into the picture before things got out of hand. This time, it was permanent. New leadership was trying to figure its way into the picture to take Shredder's place.

In Japan, there was a girl practicing her fighting skills. It turned out that she was the adopted daughter of Oruku Saki. Her name was Karai.

She had been raised and trained by the Shredder. But her fighting style was its own, a quite a bit faster and often times, even more extreme too.

Her phone suddenly began to ring. She went to get it. "Yes." She said.

"Mistress Karai. It is as we feared. The city of New York is at war." The male voice said on the line.

"I see. Thank you." Then she hung up.

Karai knew what it meant if the city was at war. It would be her job to restore the Foot to the top of the ranks. She ordered her jet be filled because she and her men were headed there.

Once on the way there, she was given a laptop that had a security coverage of some strange creatures fighting the Mob and Purple Dragons at one time. It was just four green creatures.

She smiled. This was something new. "Interesting." She said.

Karai vowed she would catch up with these strange creatures and talk business with them. She had yet to see if these creatures were her friends or enemies. After all, they had killed her father, but only because he had been so dangerous.

…

In New York, Leonardo was feeling the most responsible for what was happening to the city. He felt like it was his fault that because the Shredder was gone, now the city was at war again. He wanted to stop it, but he didn't know how to.

After a failed attempt at getting his sword into an aimed target board where he really wanted it to go, Leo was saddened.

Then Splinter came up to him. "Is there something wrong, Leonardo?"

"I just feel like what's going on above is our fault, Sensei." Leo replied.

"We did the city a favor." Raph came over out of nowhere.

"He was dangerous, Leo. We had no choice." Don said.

"It still feels like it's my fault." Leo said.

"We can't stop a whole war, Leo." Mikey said.

"I just feel like I have to do something." Leo said.

"Right now, Leonardo, you must let this go." Splinter said.

"I can't, Father. I can't!" Leo said and began to leave the lair.

"Leonardo! Leonardo!" Splinter called after him, but he was gone.

Raph wasn't too happy about this either. He and Leo had recently been out on patrol together and had gotten into a fight about what was happening. He knew Leo felt responsible, but he didn't. He was liking not having to fight the Foot all the time anymore under Shredder's orders and not having to worry about Mr. Spiky Pants, as Mikey had once called him that.

The family knew that Leo was going to be out there trying to find a solution to trying to stop this war going on in the city. It was going on and even some innocent people were getting caught in the cross fires.

Leo went out on a solo mission to just see what he could do. And if he had to delay going back to the lair for awhile, he would. He was old enough to take care of himself.

But Splinter was too worried about him.

"There is a chance Leonardo might get into trouble without you there to help him get out of it. Go and find your brother." Splinter ordered Don, Raph, and Mikey.

Raph was still ticked about this, but he went with his brothers to find their leader.

The trio of turtle brothers searched all over the city for Leo, and they figured to try to find him by any place that had Foot activity going on would be best. At least it was a start.

They later did find Leo on an old building that was real run down, that looked like a fire had taken it to shambles. From their perspective, when Leo took out his swords, it looked like he was about to take on the whole Foot clan, and from the last time he had taken them on all at once, there would be no good chance he would make it out from being uninjured. They couldn't let that happen. They had to stop him.

Leo had his katanas in his hands. "Looks like it's just me, against all of them." He said in a low voice, trying to get the proper go ahead feeling of going down to face the enemy, the Foot ninjas, all of them, and there were many of them, close to 100 or more.

All of a sudden, Leo felt someone grab his arms and pull him away from the hole in the building. "Hey! What the-! Let me go!" He shouted. Then he saw it was his brothers.

There was a chance the Foot had heard them.

"What are you guys doing here?" Leo asked.

"Making sure you don't get into something that you can't get out of on your own." Don replied.

"We shouldn't be here, Leo. This ain't our war." Raph said in a low voice.

"Any chance the Foot heard us?" Mikey asked. His question was soon answered as tons of Foot ninja gathered on top of the building. "Yep, I think they heard us." Mikey said.

Yes, there will be action from the Monster World too in this part, off and on. Stay tuned to see what the action brings.
