Description
Choi San-Hae is the main protagonist of Digimon Adventure 02 and a new Chosen Child who inherits the crest of courage. As an eleven-year-old student, he attends the same class as Ricky and Shin Na-Ri and has known Shin Tae-Il and Han So-Ra from the school soccer team for some time. He lives with his parents and has an older sister, Jun. San-Hae's connection to the Digital World began during his early childhood when he, along with his parents, was among the people captured by Myotismon and isolated at a broadcasting station. This early incident contributed to his eventual selection as a Chosen Child.

San-Hae is characterized by his hot-blooded, optimistic, and mischievous nature, embodying a spirit that hates anything overly rigid or angular. While often seen by peers as a typical hot-headed and somewhat simple-minded boy, he possesses an unexpectedly strong and positive personality. His favorite activities include physical education and lunch, though he is not particularly athletic and has been shown to struggle with academic subjects like mathematics. Despite these shortcomings, he demonstrates a practical intelligence in areas like English, where he can communicate comfortably with international Chosen Children. A defining trait is his unwavering courage and lack of fear, which becomes most evident when others are shaken. He is notably satisfied with the present and has no major complaints or worries, a mental fortitude that makes him immune to deceptive techniques that prey on inner doubts.

His primary motivation stems from a deep admiration for his senior, Shin Tae-Il, whose influence is so strong that San-Hae initially wears goggles as a symbol of this respect. He harbors an unrequited crush on his classmate, Shin Na-Ri, and often finds himself competing for her attention with his rival, Seo Jung-Woo. Over the course of the story, San-Hae’s motivations grow from simple admiration and personal desires into a genuine, selfless drive to protect others, leading the group when their resolve is tested.

In his role within the story, San-Hae acts as the central figure among the new generation of Chosen Children. His partner Digimon is V-Mon, with whom he has a very strong calibration. He is known for being the first among his group to have his Digimon evolve, and he can Jogress evolve V-Mon with Jung-Woo's Digimon to form Paildramon, which can further evolve into Imperialdramon. San-Hae also possesses the ability to use Digimentals for Armor Evolution, including the Miraculous Digimental, which allows V-Mon to evolve into Magnamon, a member of the Royal Knights, though this power is temporary.

San-Hae's key relationships are central to his development. His rivalry and friendship with Seo Jung-Woo are essential, as they must cooperate to achieve their strongest Jogress evolutions. His unrequited feelings for Shin Na-Ri drive much of his early behavior, though he ultimately starts a family with someone else years later. He shares a close bond with his senior Shin Tae-Il, from whom he inherits the legendary goggles and the crest of courage. He also develops a strong partnership with Michael, an American Chosen Child, during the Christmas world tour.

San-Hae’s development is marked by a gradual maturing of his natural courage. A pivotal moment occurs during the final battle against a revived and powerful Myotismon. While the other Chosen Children are paralyzed by the fear of losing their partners, San-Hae remains utterly unafraid, fighting alone with XV-mon and proving that his unwavering spirit is a key to turning the tide. This event showcases his growth from an impulsive boy to a reliable leader who can steady the resolve of others. About twenty years later, he has cut his hair short and lives in the United States, where he successfully opens a ramen restaurant chain, becoming a businessman. In later appearances such as Digimon Adventure tri., San-Hae and the other 02 members are rendered missing after being defeated by Alphamon, though they eventually return to the real world and recover their health.

Notable abilities of San-Hae include his exceptional proficiency as a Digimon tamer, allowing V-Mon to access multiple evolution paths. Through the Digimental of Courage, V-Mon evolves into Flamedramon, and through the Digimental of Friendship, into Raidramon. His most powerful individual evolution is Magnamon, achieved with the Miraculous Digimental. In a Jogress with Stingmon, the partner of Seo Jung-Woo, he forms Paildramon, which then further evolves into the Ultimate-level Imperialdramon. His signature weapon in this form as Imperialdramon Fighter Mode is the Positron Laser.
