Reon Sai Leonardo is a 17 jaar old mahogany lion from Icarus Island. Reon grew up in a rough part of Icarus where there were a lot of gang members lurking around. His father, Leone, was worried about his son every time he walked to school, thinking that he was going to get attacked door thugs and killed, so he taught Reon how to do tae kwon doe so that he could defend himself. It took years to perfect it, but Reon managed to learn tae kwon doe. With his newly found techenics, Reon beat up every single thug and gang member that came his way. However, he started to abuse this techenics at school, and got expelled from attacking the assistant principle. His father was afraid that he was going to become a thug if he wasn't in school, so he sent Reon to stay with his mother, Femleon. 3 months later, Femleon was telling Reon that there are people who can't be attacked physically, so she taught him how to use heliokinetic powers. Years later, Reon decided to go out on his own so that he can find someone to fight. On his voyager, he met Liza, the leader of a group called "The Neko High Force, a unit of felines that go on missions to keep order in the Western Islands. He challenged Liza to a dual, and Liza accepted only if this would happen. She zei if she wins, Reon would have to kom bij the Neko High Force. Reon agreed and the fight began. Reon lost the fight all because he made a miscalculation, and didn't time his attacks right. Reon keep his word and joined the Neko High Force, then became the 2nd in command.

Reon is very competent, and calm. Though sometime a little bossy, but he tries to lay off. He loves to eat fried barracuda, but has a rivalry with Danny The Hyena.

Reon mainly fights with physical attacks, oppose to range/chemical attacks. His has great speed, and stamina. However, he tends to get careless, and go after his opponent haphazardly. Reon's heliokinesis comes in handy when he's in a tight place.
