Olympia

The Olympia (パワーオブヒーロー) is a Keychain for Sora's Keyblade which appears in Kingdom Hearts and Kingdom Hearts: Chain of Memories.

In Kingdom Hearts, the Olympia is in a chest at the Coliseum: Lobby, but the chest will not open until Sora completes the Phil Cup, Pegasus Cup, and Hercules Cup. In Kingdom Hearts: Chain of Memories, the Olympia is the signature Attack Card for Olympus Coliseum.

In Kingdom Hearts 358/2 Days, during Roxas's dreams of when Sora defeated the World of Chaos at Kingdom Hearts, the Keyblade is in its Olympia form.

Design
The handle and sides of the Olympia's guard are gray columns. The base of the guard is white, and the top of the guard resembles two white arms flexing their muscles. The shaft of the Keyblade white with gray edges and "Hercules" engraved into the white section. The teeth are set very high on the Keyblade, and are attached to the tip. They resemble clouds. The Olympia as a whole is meant to resemble Greek architecture, and appears to be carved from marble. The Keychain is made of several silver links, save for the first one, which is gold, and the token is the Olympus Stone.

The Olympia's name references an ancient Greek city of the same name, which was where the first Olympic Games were held.
