Although Square Enix originally wanted Mickey Mouse to be the main protagonist of the Kingdom Hearts series, and Disney wanted Donald Duck as the protagonist, the role was eventually set as Sora, because Tetsuya Nomura wanted a human protagonist.Early on, Sora was designed as a young lion/human hybrid, wielding a chainsaw-like weapon with a lion's head keychain. The merging of Sora's design with elements from Square's proposal is referenced by his original costume, which shares many elements with Mickey's.
