SkunkyArt | GeluAteKurama — tmnt2012-AU-Oroku Saki rat

Teng Shen didn't die and Hamato Yoshi/Splinter defeated Oroku Saki/Shredder but let him live with the agony and embarrassment of his defeat. So Yoshi and Teng lived happily with their daughter Miwa/Karai.

While Oroku had no other choice but to leave as everyone who once knew him lost all respect for him and felt petty over his existence. Over the years, he has had anything but regret and pain. His mental and body health became an issue, it was almost as if he was dying from the inside.

He tried to look for help but mostly failed because of his anger issues. Eventually, the TMNT 2012 plot thing happen and he was mutated when he went to buy 4 little turtle pets as a suggestion from his therapist.

Oroku thought of better leaving the mutated baby turtles in a better place (maybe with Yoshi and Teng if he could ever find them) but with his new form and past he knew that no one would accept him or the little turtles, and remembered how much he regretted hurting his adopted family he took the little turtles as his own and really but really just tries to be a good dad...

He still wears the Hamato clan symbol as just a memory and a sign of respect as he also preserves his deadly metal claws, though they became nothing but rusty metal.

He may be angry 24/7 but will always keep his composure and try to use the peaceful route as they once thought him to do, but if the situation demands it, he will scratch and be hard.

When the Krang started to look for him and the turtles, in one fight he lost his tail and he hides that from everyone.

He started to train his kids when they were at least 10 as he wanted to give them enough space so they could enjoy their childhood before confronting the world. Shredder also took his time to make suitable weapons for his kids (though Tenoch/Donnie made his weapons with better quality and in little time), Shredder is so proud of that.
