Hercules

A demigod of Greek mythology, a refreshing and good-natured young man, revered as a heroic figure by the gods and called "Brother" by the Valkyries. Being a demigod, he opposes the end of humanity and intends to protect humanity if he wins as the representative of the gods in Ragnarok. Ares, who once fought Hercules, has said that the essence of Hercules' strength is not only his indomitable spirit, recognized even by Zeus, but also his "resilient heart," earning him the title "Indomitable God of War."

His divine weapon is a club shaped like a lion's head. The tattoos on his body, which spread each time he uses one of the "Twelve Calamities and Sins" – divine techniques he mastered just before becoming a god after completing twelve labors – cause immense pain that would make a normal god faint even if they spread just one millimeter. If they spread over his entire body, he would completely vanish.

As a human, he lived in Thebes under the name Alcides and from his youth, he lived by the principle of being an ally to the righteous. During Ares' invasion of Thebes, he drank Zeus' blood from a temple in Thebes and endured the ambrosia, gaining the power of Zeus, the god. He single-handedly devastated the vanguard of the divine army and fought Ares to a standstill until Zeus stopped the fight. When Zeus proposed that he become a god, he made Zeus promise never to harm humanity again, earning deep trust from Ares, who calls him "Godfriend."

He regards his opponent Jack, who toyed with many human lives, as scum and was initially furious with Brunhilde for choosing him as his opponent. However, during the fight, he learns of Jack's descent into pleasure from poverty and betrayal, and decides to save Jack from his suffering. At the end of the battle, he praises Jack as a formidable opponent. Satisfied with his fight against Jack, he entrusts the salvation of humanity to Brunhilde and completely vanishes. Many, including gods like Ares and Loki, as well as Brunhilde, Göll, the people of Thebes, and his opponent Jack, mourned Hercules' disappearance.
