Tenorio is the embodiment of evil. He is a man of action who serves as the antagonist against Ultima and Antonio. Little is known about him except that the villagers believe that his wife was, and that his daughters are, black witches. It is suggested in the novel that he is a warlock, but this is not made entirely clear to the reader.
Tenorio is a determined man who carries out his threats. He is tenacious and holds on to his evil aims despite having to invest lots of time to realize them.
Tenorio has a thin, hunched body. His face is thin and drawn, with tufts of beard on it. His lips are thin, and his eyes are dark and narrow, with an evil glint emanating from them.
