I have a theory that someone, maybe a group, or maybe a single person, placed the energy steroids in the hands of the fishmen purposely. It may have been to use the fishmen as test subjects or maybe it was placed there to cause chaos among them. The side effect would be an added bonus or maybe the main reason of placing them there knowing that the fishmen would choose them for their power anyway. In short, Im saying that the energy steroid may have been introduced to them solely to hurt them in th end. This is just a theory. What do you guys think?
