Leon is an anthropomorphic F-Zero pilot, who makes his debut in the 1998 N64 game, F-Zero X.
Twelve years ago his parents were killed in a big war on the planet Zou. His species had natural advantages over humans, such as sharper reflexes and natural instincts. He met Super Arrow and Mrs. Arrow when the couple were vacationing on his planet. They decided to give him a chance in racing the King Meteor.
Given his skill, it was decided he would be sent to the F-Zero Grand Prix to be a symbol of hope for his ailing, war-torn planet. Although he wasn't considered especially bright, he proved to be a natural at the F-Zero races, despite his young age. Although he was teased at first by other pilots, his continued performance has given him a good track record. It's his hope to become champion so he can use the money to save the children of Zou from poverty.
- He coaches a soccer team for children in his spare time. He is a wrestler as well.
- Leon also bears a passing resemblance to Wolf O'Donnell of the Star Fox series. Interestingly, James McCloud, an obvious reference to a character in the Star Fox series, is in the F-Zero series as well, even resembling the appearance of said character. Leon even shares the name of one of Wolf's lackeys, Leon Powalski.
- When he isn't racing, he is the head of an orphanage back home. He often dedicates most of his actions and winnings to the children in said orphanage.
