Digimon Battle Spirit

Digimon Battle Spirit is a fighting video game originally published by Bandai and developed by Dimps for the Japanese-only WonderSwan Color handheld system under the name Digimon Tamers: Battle Spirit (デジモンテイマーズ バトルスピリット, Dejimon Teimāzu Batoru Supiritto).

The game features characters and Digimon that were included in the first three seasons of the animated series of the same name in a somewhat simplistic fighting scenario, and also has slightly arranged samples of the show's soundtrack.

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 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.
