In the Plutonet Universe, dogs possess a level of intelligence that is ten times more advanced than humans. A life well-lived to them means being crowned the Ultimate Alpha Dog - the best of the best! Thus, these dogs spend days and nights building and collecting engines, assembling the best robots to use as their fighting weapons. They travel from planet to planet, bringing the sounds of metals crashing and grenades exploding with them. And the battles won't stop until there's only one left standing - the one to conquer all lands, the Starbots King!
