Future Leo - Good Future?

Splinter died when Leo was 29 years old, 17 years ago, and now Leo is 46. Raph also died, but when Leo was 34, but Donnie transferred his consciousness into a robot that looks almost exactly like him, except now the robot representing Raph is about 5 meters tall. Donatello made a mechanical arm for Leo when he lost a fight with the Kraang. Mikey managed to become a master, opening portals and teleporting with ease, and even grew his hair out (I don't know how, but it's okay, since they are part human).

He was restless and irresponsible when he was younger, but with the job of being a leader and the certain "traumas" he went through, mainly the one involving the necklace and seeing his brother, Raph, die in front of him when a Kraang pierced Raph's head, even though he was "revived" as a robot by Donatello some time later.

They went through an apocalypse, the Kraang invaded Earth and tried to dominate it, but the brothers managed to stop them, and now the city is slowly rebuilding itself, they were more recognized for their heroic acts but still preferred to stay protecting the new New York in the shadows

lost his right arm and now uses a mechanical arm that Raph, his brother who died and Donnie turned into a robot, used in an old version, muscular, tall, red-eared turtle, developed a small tail when he passed adolescence
