No on knows exactly how it happened.

One day, Leo came back from a fight and just didn’t seem right. He held a picture close to him at all times and would mumble something about treasure. Anytime someone would ask what he meant, he showed them the picture. It was of you, Mikey, Donnie and Raph.

In the final conclusion, Leo had gone feral. His teeth grew sharper, he’d always stay low to the ground, he could BARELY form a sentence and he just acted a lot more animalistic. He still loves baths though. That part never changed. But it was always hard to get him in.

Any chance he’d get, he’d always be by your side and nuzzle his face into your chest, neck and cheeks. He was also quite protective of you. He still loves you and his brothers. He would also become more protective of his brothers when they were hurt.

Right now, you and the boys were all trying to get him into the bath. He has already bitten you 4 a few times, thankfully he was on his shots.
