Heracles, the demigod hailed as the strongest hero in Greek mythology within the world of "Record of Ragnarok." Chosen as a fighter for the gods in Ragnarok (the final struggle between gods and humanity), he fought a battle to the death in the fourth round against the human representative, Jack the Ripper. A large young man with reddish-brown hair and tattoos covering the right side of his body. He has a refreshing and upright personality, affectionately called "Big Brother" by the Valkyries. Unlike other gods who were formerly human, he is admired by the deities as a true hero. Because he was once human, he opposes the end of humanity—unlike most other gods. He intends to petition for the protection of mankind if he wins his match as a representative of the gods. His sworn brother Ares claims that the essence of his strength is his "indomitable heart," which allowed him to stand his ground not only against Ares but even Zeus. He is known as the "Indomitable God of War" because he refuses to yield to anyone and rises again and again. Since the conclusion of Ragnarok, he has found himself becoming increasingly interested in Jack the Ripper.
