MrSmartguy

MrSmartguy is a Sheikah born in Kakariko Village 20 years before the Great Calamity and brother of Impa and Purah. He learned about the Guardians and Divine Beasts at the age of 5 and started training for combat at the age of 10. By the age of 15 he could already take out a white lynel with ease. At the age of 20 he excavated a Guardian and managed to activate it. He moved to Castle Town a week before the Great Calamity. He and his Guardian survived the attack and he was one to rush Link to the Shrine of Resurrection. He came to hate Link after he was caught dating his girlfriend, Riju. He broke up with Riju after she seemed to hate him now for some reason.

Early life
Little is known about MrSmartguy's early life, but as I (as the author) have provided the information in the forms of flashbacks. MrSmartguy was born four years following his older sister Purah's birth. One year later, Impa was born and life started to change for him. Four years later, he learned about the Guardians and Divine Beasts from an ancient legend passed down in his tribe for generations. Whenever he remembers this, he thinks back to the "good old days" when he wasn't preoccupied with research. Then the raids begun and he was required to learn combat. He was prodigious, destroying any bokoblin in his path. Then only a few years later, his mother was murdered right in front of him. Filled with feelings of rage and vengeance, he defeated all Yiga Clan at the village.

The Great Calamity
After moving into Castle Town with his new companion, MrGuardian, Calamity Ganon attacked. MrSmartguy fled whilst hiding under MrGuardian for safety. He later escorted Link to the Shrine of Resurrection. After that he stayed in Kakariko as a guard for a hundred years.

Anti-aging
After 100 years had past, MrSmartguy went over to Hateno Ancient Tech Lab. Purah had created the anti-aging rune and MrSmartguy got younger, making him the longest living Sheikah in history that did not become a monk.
