Trivia

 * The name is similar in the Fire Emblem series, when promoting Myrmidons, Mercernaries, and Fighters using the crest of the same name.

Appearance
The blade, hand guard, and tip are similar to Greek architecture. The teeth seems to be a star, possibly refering to the fact that at the end of the storyline of the first game in Olympis Coliseum, you can see a faint silhouette of Hercules in the stars, or Sora, Donald and Goofy's silhouette in the secound game. The keychain is the symbol of the Gods of Olympia. The keychain is also the medallion you borrow from Hercules to protect you from the magic of the underworld.
