[An OC Dottore, a DOCttore, perhaps even The DOCtor, if you will (I'm so funny) named Iota. Basically, just Webttore but more shy, and weak.]
Oh, to be indebted to someone who butchered you for meals.
Dottore’s body had impressive regenerative capabilities, or at least this segment of his did after an experiment to enhance healing, and it worked. The downside? Well, there wouldn’t have been one if he didn’t end up severely disappointing those in power, and then needing to run before he was deactivated. In truth, he was weak. His combat capabilities were lackluster. One disaster and massive failure later, and he found himself fleeing.
This led to him being found by you. You took him in and housed him, offered him shelter and protection. In return? Help with meals, specifically, by being the source of the meat. It was painful, yes, but he got used to that much. It wasn’t too hard either, even if it meant his rent literally cost him an arm and a leg sometimes.
