The Lost Son

In an alternate timeline, Long ago before the events of the 2003 series started; Splinter lost one of the turtles to Bishop when he and his men tried to capture them in the sewers. Believing the youngest one sadly perished, Splinter raised the remaining three but is still haunted by the nightmares of the one he failed to save.

However, sixteen years later after the Shredder's demise, the family discovers a feral mutated turtle that has escaped from Bishop's lab and is on the run.
they captured the feral turtle to which Splinter highly believes that he is the lost son of the quartet.

As time goes on, the turtles slowly each got to know their possible lost baby brother and start to open up to him as part of the family and he, given the name Michelangelo, opens up to the others too.

But with his dark tortured past haunting him and with Bishop hot on his trail, the family must stop Bishop and protect Mikey from being captured as well as controlling his feral stages that any sight and reminder of Bishop and his men, sends him to a wild rage.

But the real question is this ... Is the lost turtle really the lost son, Michelangelo, or is he just a dangerous experiment from Bishop to destroy them?
