Shadow was born from a very rare mix of wolf. Then his parents died when he was just a pup. He had to learn how to hunt by himself. When ho grew older there was a massive fire. he got his leg, snout, and tail burnt off. A mad scientist took shadow into his lab and started working on him. He got robotic parts and could speak human language. https://www.tinkercad.com/things/7vkmZ8k1EKr-shadow/edit
