Cato is really protective over his younger sister Zelda. He often protects her from his twin Thana when she bullies the two of them. He struggles with his need to eat flesh/blood, and because of this he is prone to stalling until he goes into fits of blind hunger where he follows the one need that drives him; the need to eat. He often sees his hunger as a separate entity from him because as his hunger grows, he changes. His hair starts turning light grey from the roots down. When he is in the throws of Blind Hunger his hair is completely light grey and his eyes turn a glowing red.
