The Digital World, a computer-generated subspace that exists between all forms of digital devices, and home of the creatures known as "Digimon" is under attack by a malevolent and powerful force known as Millenniummon, who seeks to corrupt all the data present in the world and modify it to his own designs. In response, several Digimon and their human companions have set out to stop Millenniummon and his minions before any irreparable harm can be done. This is accomplished in a very round-about and a-typical way to the fighting video game genre, by finding and defeating as many opponents as possible on the way.

While structured very similarly to a conventional fighting game, Digimon Battle Spirit is much more like a barebones representation of the genre, mostly due to the limitations of the handhelds it was released on. Each character only has a handful of special attacks they can perform, with the two action buttons, A and B, allowing them to jump or attack respectively.

Each match is won by collecting small blue/red spheres called "D-Spirits". These are obtained by hitting your opponent, which causes a few of them to fly from their body and scatter across the battlefield. Different attacks can produce more spheres to fly out, and the player who has collected the most by the time the round ends wins. Each character can also digivolve into their most powerful or "Ultimate" (Mega) form by touching a flying Digimon named Calumon that appears every so often in each stage. This form grants them different, more powerful attacks for a limited time.

As the player advances through each stage, they will occasionally have to battle a character named Impmon. Winning or losing this encounter has no bearing on the actual game progression itself, and only serves to award more points. In the final stage, the Digimon must face off against Millenniummon himself.
