Leomon is a minor hero in Digimon Adventure and a major hero in Digimon Tamers. He can also Digivolve to SaberLeomon (despite skipping to the Ultimate Level). His known attack is Fist Of The Beast King. He is Ogremon's rival. He is partner of Jeri Katou in Digimon Tamers.
He resembles a humanoid lion warrior that weilds a mighty sword.
Leomon went face-to-face with his rival, Ogremon, he was infected by Devimon's Touch of Evil, turning him evil. Luckily Tai and Matt raised their Digivices and released the Black Gears from Leomon's body, returning him to normal.
Later, he returned as SaberLeomon to rescue Mimi and Joe from MetalEtemon. He challenged MetalEtemon to a battle as SaberLeomon, but was fatally wounded by MetalEtemon's attack. As he lay dying, Leomon said that he will be reborn in Primary Village.
Leomon first appeared from a rainbow when Jeri and Calumon were attacked by Kumbhiramon and became Jeri's partner after he defeated the rat Deva. While journeying in the Digital World with the Tamers to rescue Calumon, Leomon's partner, Jeri was kidnapped by an eight-headed serpent named Orochimon, whom he defeated and rescued Jeri. In the end, during Beelzemon's attack on the Tamers, Leomon was killed by Beelzemon by strucking him through the stomach, and as Leomon lay dying, he reminded Jeri to be brave and she has a lion's heart. After that, his data was also absorbed by Beelzemon, leaving Jeri mournful, upset, and sad. Takato then went into a rage to avenge Leomon's death.
Later, during the D-Reaper battle, while attempting to rescue Jeri and Calumon, Beelzemon showed an image of Leomon himself and used his attack, Fist of The Beast King, and blasted through a hole to try to pull Jeri out.
