In Kingdom Hearts, the Metal Chocobo is a reward for defeating Cloud in the Hercules Cup.
The blade resembles Cloud's metal Buster Sword, and the Keychain's token is a Chocobo. It possesses a red handle and a brown guard. At the base of the blade, there are two holes, one on top of the other, and there are three holes adjacent to the teeth.
Although the Metal Chocobo's name is directly derived from the Chocobo of Final Fantasy, the appellations of its upgrades in the Japanese version of Kingdom Hearts Re:coded are actually derived from those given to the various forms of Bahamut in the Compilation of Final Fantasy VII, in which Cloud is a major character.
In contrast, the appellations in the English version play on the "Metal" portion of the name: Iron (Fe), Silver (Ag), Gold (Au), and Platinum (Pt).
