This is  MY AU THIS IS DIFFERENT FROM THE ORIGINAL AU . If you wanna use it we can. If you wanna use yours or the cannon au we can. Im not picky NO TCEST Though.

Now onto my au:

- Karai is neither splinters or shredders daughter. She is another Hamato soldiers daughter (hence her slightly blonde hair.

- Leo is 20 Raph is 18 gonna be 19 Donnie is 17 going to be 18 Mikey is 16

-  When I was about Mikeys  5th Bday the older three went to the surface for a present. They eventually split for a while.Hence Donnie meeting April and Casey. And Leo meeting Karai.

- Leo and karai started the group.

- Two years after the friend group was started Mikey was introduced.

-The adventures started after that.

- Karai found about the turts being hamatos. She told shredder. He started the war against them.

-Karai betrayed them 

- 6 months after the betrayal the turts and splinter found that she was Miwa

- Karai rejoined the hamatos after that 

- after Karai rejoining splinter pushed the turtles out of the 'my sons spotlight' basically dropping them as sons and saying they are his students.

- Cue the space adventure and everything before splinters death 

- a few months before his death splinter found  Karai was not his bio nor Shredders thus dropping her as his daughter

- up until a few days before his death splinter considered what was supposed to be his children students. He had a change of heart 6 days before his death.

- Even after being reowned Leo and Karai deemed themselves no where near siblings or even step siblings. Started dating.

- Mikey chose Renet over Shini

- April chose Donnie

- Raph and Mona got promise piercings on their tails. Signalling one day they shall marry.

- One day in the future Casey and Shini hookup and have a child. Then got married so their child could have a father.

-Mikey still has his electro powers after bishop said removing them could do more harm than good. He has mastered them since.

- After the ' Newtralizer incident.'  Mikey became the apple of his big brothers eyes and their pride and joy

and thats about it (for now at least)
