Sidon was designed by Yuko Miyakawa for
The Legend of Zelda: Breath of the Wild, asked to him a "passionate, dignified, and powerful character with a stronger physique than other Zora." She gave him a hammerhead shark design on his head, and his design ultimately lead to the game development staff giving him an in-universe fan club. He was initially grey, but this was changed for multiple reasons, including the fact that it is rainy in Zora's Domain when you first meet him, and a desire to make him resemble his older sister,
Mipha. Sidon has the typical design traits of the Zora, being a humanoid with features resembling a fish. He is primarily red or dark pink in colour, with a tail fin sprouting from the top of his head. As a member of the Zora race, Sidon is taller than the average Hyrulean, but is also tall by Zora standards. Due to the slow age rate of the Zora, Sidon is considered a young man despite being over 100 years old. Like other Zora, Sidon wears little clothing, but his attire features several items that reflect his status as prince of the Zora, such as his scarf, epaulettes, bracelets, and belt. Sidon's Japanese name, , is derived from the notes
ti do in the
solfege, alongside being named for the notes
mi fa (as well as other Zora characters having names derived from music terminology). According to sound director
Hajime Wakai and composer Yasuaki Iwata, both of these pairs of notes were intentionally used to create the siblings' respective musical themes and used as
leitmotifs elsewhere. Sidon is the prince of the Zora and a leader of its people, sporting a friendly, brave, and optimistic personality, reflected in his tendency to strike poses during gameplay. He has also been noted for his muscular physique and smile, which have resulted in many fans treating him like a heart-throb. When designing his personality, producer
Eiji Aonuma and game director
Hidemaro Fujibayashi described him as "overly enthusiastic at first," feeling it was "too much" until they improved it, at which point they grew to love his character. They were unsurprised by how popular he became. Sidon is the son of King Dorephan, the ruler of Zora's Domain, which makes him next in line as ruler. Sidon is voiced in Japanese by Kosuke Onishi and by James D. Mortellaro in English in
Breath of the Wild and
Hyrule Warriors: Age of Calamity. ==Appearances==
