Infernus

This is Infernus the ultimate bad guy in my story(or about to be). He is a Triosus(the three wings pegasus). Triosus are very powerful but they are also peaceful species. But something has corrupted one of them and turn him to evil. With his dark powers he turn the Triosus's city and everyone who live in it to vanish in a single day. Now they are only three triosus still existed but who is the other two I can't tell you that.
