Long before humans walked the Earth, a cosmic force called Monsuno streaked through space, blazed down through the atmosphere and struck the planet, bringing chaos and ending the age of the dinosaurs before disappearing. Now Monsuno has returned, and the fate of the world is in question. In this second season, five teenagers who crave adventure are back in the thick of monsuno battles, and Jeredy Suno has at last returned after being missing. Old enemies remain, and new ones join them. The Forge Resistance is a manufacturer set on wrecking the world with Wild Core Bombs. The S.T.O.R.M. Strike Squad, chosen by Charlemagne, acts as a mirror image of Team Core-Tech. The Hand of Destiny gathers ancient tribes that retreated underground ages ago. Six, a teenage clone of Dr. Klispe, is hunting Team Core-Tech. Chase and his friends face harder fights and fresh problems, and they must bond with their monsunos more closely than ever. The result is an action adventure series built around monsuno battles and a threat to the whole planet.
