Heracles is a member of the Hero Faction. He carries the spirit of the Greek mythological hero Heracles, until it was confiscated.


Heracles is a two-meters tall man with a well-built body and has shoulder length gray hair. He wears what appears to be an attire of a Japanese school uniform (more specifically, the gakuran worn by Japanese schoolboys in the fall), covered by what could possibly to be Greek inspired armor.


Heracles is shown to be arrogant, overconfident, brutal, stubborn, assertive, and pugnacious. Heracles loves battles and take great pride and confidence in his name and his skills. He often has a tendency to look down upon his opponents, as shown when he claimed that a "defect" like Sairaorg cannot possibly defeat him just because Sairaorg can't use any special demonic powers. He also has no qualms in employing dirty tricks to defeat his opponents like when he attacked a bus with children in it, all in order to defeat the Sitri group.


Not much is known about Heracles' past, other than that at some point before the series, he was persuaded by Cao Cao to join the Hero Faction.


The Heroic Oppai DragonEdit

He appears in Volume 9 during Issei's class trip to Kyoto, where he manages to defeat a drunken Rossweisse.

In Volume 12, Heracles fought against Sona Sitri and her peerage, defeating them by using the children of the Underworld as hostages. He later fought against Sairaorg Bael, looking down upon Sairaorg for not having any special demonic powers. However, he was outclassed by Sairaorg and later defeated after he abandons the Chaos Break doping and tried to face Sairaorg head-on. He was then captured by the Devils and Fallen Angels and was taken to be interrogated.
