Trivia

 * The name is similar to an item in the Fire Emblem series; this Hero Crest is used to promote members of the Myrmidon, Mercernary, and Fighter classes in several games in the series.
 * Referring to a recent gameplay video, this keyblade is set to appear in Kingdom Hearts 358/2 Days.

Appearance
The blade, hand guard, and tip are similar to Greek Ionic architecture. The teeth seem to take the form of a star, possibly refering to the fact that at the end of the storyline of the first game in Olympus Coliseum, you can see a faint silhouette of Hercules in the stars, or Sora, Donald and Goofy's silhouette in the second 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.
