Somewhere along the line, Donnie had decided to become a doctor. Maybe not an official one with a degree, given their circumstances. But a self-taught doctor none the less. They could really use a medic, there was no one they could turn to if they were injured, and he deemed himself to be the best turtle for the job, given his interest and ease for learning.

Besides his brothers... well let's just say those topics and the requirements weren't their strongest suit.

Things became easier once he'd built a laptop and connected them to the internet, giving him access to more knowledge than he could ever consume. He sure was glad he was also an engineer, an inventor and chemist at the same time. Some things you didn't actually need legs for, which he was immensely grateful for. It also made it easier on their dad.

As he grew older he'd also started upgrading his wheelchair as he learned to build, trying to make maneuvering easier. They'd built some ramps around the lair as well and adjusted his work tables and shelves.

His brothers did help him as assistants on occasion, when he needed to reach or get somewhere he just couldn't do completely on his own. It didn't always have to do with not being able to walk. Sometimes it was just about needing three arms, or four.

he vowed to never let his brothers get so seriously damaged as he did as a child, ever. He'd do anything to prevent that, or heal them back to top shape if it ever did.
