In every region around the world, an academy has been established for new Fusion Battle trainers. And at the Castelia Academy for Fusion Battles, funded by the inventor of the Fusewatch himself, Professor Jan Brills, Class 3A has proven itself to be the best of the school’s best. With that, the students of Class 3A have been submitted as the school’s delegation to the qualifying round of the first Fusion Battle World Championship. Soon, the first battles of the qualifying round will be held here in Castelia City. And six months later, the first round of the World Championship itself will be held in the grand arenas of Nimbasa City to the north.
But the Castelia Academy is hardly the only Fusion Battling school; its counterparts--the Celadon School in Kanto, the Blackthorn Foundation in Johto, the Slateport Initiative in Hoenn, and the Snowpoint Institute in Sinnoh--will also be sending students to compete. And of course, private trainers from every region will be seeking to compete.
Yet, there are always those who seek to abuse the power of Pokemon, in whatever form they can get their hands on. Already, there are rumors of those who use the power of Fusion for crime and villainy. And while you compete for the title of Fuse King in the World Championship, what could they be planning?
