Devilizing the armored serpentine beast was not actually a problem.
However, a problem was healing its wounds. The wounds it had sustained from the Space Piranhas' relentless attacks were not the only issue either. The biggest issues at hand were the beast's deformed organs, the fact that the beast seemed to be a fetus or a youngling that had been abandoned, and that he had no fucking clue how to help this kind of beast.
He could spend a tremendous amount of his energy to heal it but he was not exactly sure what the beast was supposed to look like in the first place. That was basically an invitation for fatal errors.
