Similar to the show's premises, Mamodo Battles
pits pairs of fighters, one human and one Mamodo, against each other with hopes of becoming King of the Mamodo. Though their human counterparts will occasionally get in a few licks, battles are strictly left up to the Mamodo and their collection of spells that you control. In addition, each Mamodo will also have a special mega-attack that will inflict a whole world of pain on opponents. The catch is that using one of these devastating attacks will also tire out your Mamodo. Knowing when to use these attacks forms the backbone of Mamodo Battle's gameplay, adding a layer of strategy to what would otherwise be a normal fighting game.
Other modes will also be included, such as a Develop mode that allows you to build up your Mamodo's skills and a Bonus mode that will unlock special Zatch Bell! trading cards. Nearly all of the characters from the show will appear in the game, including a special character or two that must be unlocked.
