Hidden Dragon

The Hidden Dragon is the third keyblade available to Sora in Kingdom Hearts II, preceded by the Kingdom Key and the Star Seeker. It is physically weaker than either of the keyblades available at the time, but stronger in magic. It's design includes the medal Mulan received from the Emperor for helping to save the Land of Dragons.

Acquisition
The Hidden Dragon is acquired after clearing the Land of Dragons for the first time. Once Shan-Yu has been defeated, saving the Emperor from capture, Mulan and Sora are commended for their service. Mulan receives a medal bearing the Emperor's crest, and Sora earns this keyblade.
