Based on TMNT 2012 season 3, Serpent hunt, the turtles interfere with Shredder and the foot clan, while he tries to retrive Karai from Anton Zeck and Ivan Steranko by making a deal. Leo only wants to free Karai and get his brothers out of this mess by any means necessary, even if it costs him his own life. (The story will be almost like the original one, only that the ending will be somehow different and the following episodes will take a different turn, but there will be episodes similar to the show too, just a bit altered)
*Disclaimer: I don't own the TMNT or it's characters*
(Thought I'd try a description)
Raphael accidentally hurts his baby brother, causing Mikey to leave the lair in a fit of anger only to be captured by Shredders assistants. The remaining turtles have to get him back but the only way is to get caught themselves.
A few months have passed and the turtles are now in outer space fighting for their lives and everybody else's, can they do it?
