Hercules

One of the world's most advanced robots, he participated in the 39th Central Asian Conflict as part of the peacekeeping forces. On the front lines, he, Mont Blanc, and Brando drove out the Persian army's robots. Like Brando, he is the undefeated world champion of the Euro Federation and Greece in pankration suit matches. Brando is both his best friend and his unrivaled rival, with their past four matches ending in draws due to their evenly matched skills. Known as the "God of War" in the wrestling world, a monument depicting his victory pose stands near the Parthenon, making him a national hero in Greece.

He has a stoic personality, referring to himself as a "machine" and a "killing machine," and his civilian body gives the impression of a stoic martial artist. He does not engage in "imitating humans." During the Central Asian Conflict, unlike other top-tier robots, he did not express doubt or rejection of war, but after the war, he became aware that he could no longer deliver the final blow in matches and began to understand "hatred" and "compassion."

He collected the scattered remains of his friend Brando over the Black Sea and used his own resources to search for traces of Pluto. Although Epsilon stopped him from seeking revenge, he understood that he was already being targeted by Pluto and saw Pluto as the "ghost" of the robots lost in the war's devastation, challenging him to settle the score. To avenge Brando, he borrowed a military suit and engaged in a fierce battle with Pluto, inflicting damage but was caught off guard and killed by being pierced in the head with a horn.

Like Brando, he has multiple bodies, but unlike Brando, only his electronic brain is transferred. His humanoid body resembles a European male in his 30s to 40s, with a muscular athlete's build. The suit design is reminiscent of the original, but unlike the original, he fights barehanded.

"The Greatest Robot on Earth" version

A warrior robot equipped with a spear of immense destructive power and a shield that generates tornadoes, riding a flying chariot. The design is reminiscent of ancient Greek soldiers. He prides himself as the "strongest robot in history" and, out of pride, insists on a one-on-one duel with Pluto, refusing to team up with Epsilon, ultimately losing after a fierce battle. In "Astro Boy," he is also depicted as a champion of robot martial arts, but he accepts Pluto's challenge and is defeated.
