Kirby's already a total bad-ass on his own, chomping enemies, cloning their powers and using those powers to kill their friends in the face. Now he's multiplied and he's unstoppable.
Look at him throwing clones of himself at that tree of all evil. Or using his combined strength to slap down that enemy that wasn't having any of it when there were only three Kirbies. Not even giant onions are a match for him.
Kirby Mass Attack looks wicked. It's due out on DS/DSi in UK this month, and US on September 19.
