At first glance, Thrax appears to be collected, sophisticated, charismatic and polite, but he’s actually a cruel, heartless, sadistic and horrendous villain. He’s sadistic, greatly delighting in causing death and suffering to people, and he is also intensely proud of his killing spree, often bragging about his many victims, among other displays of macabre and dark humor. Thrax has a tendency to be sarcastic. He always keeps a chain made of the DNA of all of his victims as a creepy keepsake.
