These characters are responsible for keeping order in their worlds by collecting tokens and battling a myriad of diverse enemies that include fictional creatures. Many of the battles take place in colorful arenas as well as compact dungeons. A main boss is accompanied by a group of supporters in each of the fights. The CPUs must use their powerful arsenal to defeat all of the foes in sight.
