Axemon

Axemon is a Demon Beast Digimon whose Japanese name and design are derived from " ". It is a younger brother who exchanged cups of brotherhood with SkullKnightmon. As a brawny fighter replete with nimble movements and limitless physical strength, it faithfully obeys its sworn brother SkullKnightmon, and battles with faith in its sworn brother in order to obtain victory. It shows off lightning-speed movements fast enough that they earned it the alias of "Running Lightning", and its top speed is so fast that you can see afterimages. However, fine maneuvers are its weak point, so its linear movements can be easily read by its opponent, and it easily collides with obstacles. However, if you see its sturdy body smashing through those and continue running with a defiant, thunderous roar, you would probably agree that the name "Running Lightning" is appropriate.
