Zacarías is a creature who appears in Jacinta’s dreams and possibly in her real life. Dressed in black, accompanied by a cat, and sometimes covered in scales, he seems distinctly demonic, but in fact he’s neither good nor bad; he tells Jacinta about the bad things that will happen in her life, but he also guides her towards her best experience: her relationship with Penélope. Notably, he shares his name with one of the Biblical prophets, underscoring his ability to predict the future. Zacarías is a supernatural counterpart to Laín Coubert, Carax’s alter-ego who is deadly and devil-like but still retains Carax’s human character.
