Digimon Rumble Arena

Rumble Arena is played in a similar matter to Nintendo's Super Smash Bros., with players being able to choose from up to 24 characters (fifteen of which need to be unlocked) from Bandai's Digimon Adventure and Digimon Tamers franchises, such as Terriermon, Agumon, Gatomon, and Renamon.
