I do not own TMNT. If I did it be even more of a anime than it already is.

The crispy Autumn air was in New York city as many people roam the streets. In the past, many people would have been scared to walk outside their homes. Usually, it was the Purple Dragons, causing the dangerous accidents in the streets, but then people soon realise gangs is not their only problem. Dangerous mutants that came from children nightmares came to life and was 10x more dangerous than the simple Purple Dragons. Some were worse the others, but humans soon realise their life was not so simple. However the Big Apple seems to once again in peace, many people just acted like the danger of before was just a bad dream. So many people acted like it didn't even happen. However, to the knowledge of four huge talking turtles, many humans friends, and not- human friends, this peaceful period was just what they needed.

Deep under the tunnels of New York, happiness brightened the dark sewage as Splinter smiles at the family he thought he would never have. Many times he thought himself and his sons would be dying by the hands of the humans, sickness, the Shredder or something else in the father nightmare the old rat dare not to think of. However 18 whole years the family has survived any danger that came their way. Many tears, bloodshed and lives were lost but it was all worth it. To see the smiles and laughter that was happening right now in their home. Splinter couldn't help but chuckle as he thought of how much his sons grown up. After the battle with Shredder and many other enemies, the turtle had become bored. So there all decisions to do something and get jobs, which was actually easier than they thought it was gonna be is.

Michelangelo the "youngest" of the four turtles seem to have matured more than the others. Mr. Murakami let Mikey stay after store hours to clean up and protect him against anyone who wanted to harm the blind chef. In reward, he has been teaching Mikey how to improve his cooking to become a "Ninja with food" as Mikey calls it. Splinter always knew if Mikey put his mind to it, he could do anything. Mikey quickly became a gold student with his cooking. Once a week on Tuesdays Mikey even cooks for the children. Since the kids are half price on that day it a plus to see the turtle chef cooking for them. Doing back flips and fighting makes believe enemies as they eat. Mikey even helps with the money and the business of the Japanese restaurant. Even in body shape, the orange turtle grew. He was able to grow a couple inches. Thought he was still the smallest of his brothers, he was still the fastest and flexible as always.

Splinter smiles as he sniffs the air to smell his son making food at this moment. Attacking his brothers who kept trying to eat the food for the party. Yes, Mikey might have mature, but he was still as goofy as ever. No one wanted him any other way.

Donatello the 2nd youngest and the smartest of his four sons had gotten a job working in April new laboratory. April had become the new boss of an old laboratory and she quickly became rich and famous for her inventions. Don usually helps at home, though his computer or go to the lab himself to help April out. Splinter himself could never understand the technology his son had become in love with. It did not matter to him, to see Don smile was all he care about. Seeing him come home with books of the science world made Splinter happy always. Don had also matured at a level also. He realises that April had feelings for Casey and him being a turtle did not help win the heart of the girl of his dreams. So many nights of crying and staying in his lab, he has accepted his faith. Don smiles at the memory of Mrs. and Mr. Jones wedding. He finally shows that he was happy for new his family.

Finally accepting that his dream girl won't be his, mostly a least.

Splinter got up from his chair and walk over to look at his sons Raphael and Leonardo who was playing a game on the Playstation 4 April gave them Christmas. He was thrilled his sons now had a better relationship than before. They both has fought less and begin to work together more than before. When they did fight, it was just for fun most of the time. Even Splinter noticed they spend a lot of time with each other. It seems they been able to work together better than when they were teenagers. Ralph has gotten a job helping Casey drive Shipping trucks at night. They both also usually were the guards at the business also. Both loving a job where they can "bust skulls for money". Ralph has also gotten better with controlling his anger issues. Meditating at night time, so his brothers ( even if they all knew they did not bring it up) to not mess with him. Everyone begin to enjoy the peace that was happening in the Earth, It took Ralph a while but he finally gave in

However, Leo was the hardest to accepting the peace in the world. He kept having nightmares of the Shredder or worse coming back to kill his brothers. At times he did nothing but train until he would faint at the Dojo. With the help of his brothers, he has begun to calm down ( though they all still train) on enemies coming back to do revenge. Leo usually travels to Japan in order to train and do daily jobs there for Ultimate Daimyo. It is a great chance to learn more about the history of Japan and to teach his friends in Japan about American.

Yes, life was looking good for the turtle brothers. For now.

" It time to eat"! As quickly as the words left Mikey mouth, his brothers and Casey surrounded the table. All drooling looking at the masterpiece on their kitchen table. Mikey smiles as his sat down at the table knowing once again he did a good job. Splinter then clears his throat, catching the attention of his family. " My sons. Today is a very important day for you all. You four have been through so much ever since you was small babies. All becoming the strong mutations you are today. Every long winter, training, fights and more had made you all very powerful. You now all birds being kicked out the mother nest to see the world. This is the time when you start seeing who you are and how your skills can help this world. So far you all have done an amazing job with that. I am proud of you, my sons" Splinter smiles as he looks at his son's smiling faces. They all then all got up and look at each other,with a secret language they made up since they were babies. The turtles then hugged onto their father. Tears going down Mikey's eyes as he hugs on to his father longer than the other brothers "N-No Mikey don't cry! I cry if you cry"! April says softly as she wraps her arms around the crying turtle. It was only a few times seeing the happy hyper Mikey actually cry his eyes out. " I-I'm just happy. Happy tears dudes." Mikey sniffs and wipes her eyes as the brothers hug him and rubs his head. When Mikey blows his nose and gives an okay smile to his family, they all finally begin to eat the feast Mikey made for them. Pizza was of course there, but others things like sushi, Fried chicken, Mac, and cheese plus more was also there. It was a strange combination of food, but hey it was a birthday party. Today they were going to break the rules.

The family smiles as they ate their food. Smiling as Splinter told stories when the turtles were babies. " I remember when the turtles had our first rough winter. We did not have many items for warmth, so for many nights my sons would cuddle for warmth. It was a sad sight yet the same time to be a sign of how nothing can break these young turtles determined minds. That was also the first year when Michelangelo had the flu. Leonardo took the role of leader fast. He seems to take control of trying to find has many dry clothes to keep Mikey warm as possible. Donatello begins to steal medicine with Ralph. I did not like how they both with to the surface, but they did leave money. Thought I had no idea where the money came from." April laugh as this as Don and Ralph both blush at this. " It was an amazing sight to see the turtles reading to him and playing games with him. They also were able to get paper and crayons for Mikey also. Which is how I believe he falls in love with Art, The very first picture was his family all smiling." Splinter smiles as he thought of how he stills have that picture to this day.

" Can we please open our gifts before Master- Father tell more stories"? Mikey said as a loud whine come out his mouth. The turtles quickly agree as the rat father smiles at them. They all walk in the living room and the turtles sat in the middle of the floor, smiling as they saw a table of gifts. Mikey got an upgrade to his computer and a drawing table, with a Manga drawing program to go with it. Don has got new tools for his lab and also he has a pet lizard. " Just someone to keep you company," April says as Don blush. Leo was gifted with new books that were only on shelves in Japan. As long with a new teapot that was handcrafted just for him. Last Ralph was given new boxing gloves with a new boxing bag." This one is unbreakable" Don says. "This new one should last the hot head much longer, well should be". With hugs of thanks and smiles, the turtles were very happy to finally be adults. The family surrounds the table as Casey light the cake. With big smiles, the family said in one big voice.

" HAPPY MUTATION DAY"!

Elsewhere a man smiles as he looks at his new subjects. They finally reach the age 18, which means he can finally start his plan.
