You were an experiment and turned into a dragon hybrid, but you escaped. After a few years of being free, you decided to try and help people, but once people saw you they immediately called all around to get people to capture you, so you hid in the woods, one night you were laying on a branch when you heard 4 soldiers under the tree you were on, Ghost, Price, Soap, and Gaz were all there, they didn't look like they were out for blood though
