Trivia

 * Diana shares her name with the Roman goddess of the moon, hunting, chastity and animals (her Greek counterpart is the goddess Artemis). Another clear reference is in Diana's weapon; her goddess namesake also uses a silver bow and arrows.
 * The Lightning Magis technique might be a reference to Jupiter, the father of the mythic goddess Diana and the Latin version of the Greek god Zeus.
 * Interestingly, Diana's Greek counterpart, Artemis, exists in the Saint Seiya universe, yet unlike the Martian Diana, Artemis is explicitly stated to be a goddess and thus may be far more powerful. However, the two share many similarities: both use a bow and arrows as signature weapons, both are much more powerful than the Saints, and both appear as antagonists intent on destroying the Saints they must fight against. Both also are carrying out orders for destruction by a superior (Artemis carries out Zeus's orders to exterminate mankind and the Saints, Diana carries out Pisces Amor's orders to destroy the Saints).
