Characteristics
Sora appears as a spiky brown-haired child who, when first introduced, wears a red shirt alongside red pants as well as a white and blue jacket covered by keychains. Upon traveling to certain worlds, Sora's appearance is altered by Donald Duck's magic to adapt to different environments such as turning into a merman within the sea. After undergoing a significant growth in Kingdom Hearts II, he is given a new outfit given by Flora, Fauna, and Merryweather similar to the previous one but mostly black. When battling, Sora's outfit can change into other designs depending on the player's choices. Sora's Keyblade's primary form is the Kingdom Key (キングダムチェーン, Kingudamu Chēn?, Kingdom Chain), resembling a classic skeleton key approximately 3.5' long, with a long silver keychain extending from the hilt, and a Mickey Mouse token on the end of the keychain. But through using Keychains, the Kingdom Key can assume a variety of unique forms. During Kingdom Hearts II he also dual-wields Keyblades but their form depending on the players' use of Keychains.
Across the series, Sora is depicted as a cheerful teenager who cherishes his friendships and states that thanks to them he gains his strength. As a result, several of his enemies use his friends as a bait to use the Keyblade for their purposes. Although Sora is not the real Keyblade's chosen warrior to protect the worlds, his actions across the series cause others to believe Sora will be able to save the ones close to him.
