In the English version, he is voiced by Paul St. Peter.

He look like original Leomon but they are in different universe.
Leomon first appeared from a rainbow when Jeri and Calumon were attacked by Kumbhiramon. He drives the rat away, and Jeri was charmed by Leomon’s handsome appearence to Leomon’s embarrassment. Jeri befriends Leomon.
While journeying in the Digital World with the Tamers to rescue Calumon, Leomon and the others befriend an Andromon (later Guardromon) who was defeated by Orochimon, an eight-headed serpent. He kidnaps Jeri as Leomon tries to rescue her, but fails. Leomon feels guilty for not saving Jeri in time, but with the help of the Gekomon, Leomon comes face to face with Orochimon. He along with Renamon and Guilmon fight Orochimon. With the help of Jeri’s Digi-Modify card, Leomon defeats Orochimon with the Darkness Wave attack.
In the end, during Beelzemon's attack on the Tamers, Leomon tries to convince to Beelzemon that to have power that he was given is not to be strong, but Beelzemon, angry by this, killed the lion warrior 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. After a grueling battle, Jeri orders Takato to spare Beelzemon’s life as it won’t bring Leomon back to life.
Later, during the D-Reaper battle, while attempting to rescue Jeri and Calumon, Beelzemon show the spirit of Leomon himself and used his attack, Fist of The Beast King, and blasted through a hole to try to pull Jeri out.
|“||Be brave, Jeri. Part of me will always be with you. Remember, you have a lion’s heart.||„|
|~ Leomon’s last words as he lay dying and being absorbed by Beelzemon.|
