Test your favorite Copy Ability and prove that you're the best! Select your power (Beam, Cutter, Fighter, Ninja, Parasol, Hammer, Bomb, Sword, and Archer) and challenge other Kirbys on one of seven different stages (Flower Land, Bubbly Clouds, Castle Lololo, Coo's Forest, Factory Tour, Dedede Arena, and Another Dimension) or take on the Time Trial challenge!
This Super Smash Bros.-esque fighting subgame is quite entertaining and I've practiced for a decent amount of time to become quite the Hammer main. I have personal hopes to see some influence in at least Super Smash Bros. 3DS as a nod to the similar style and to give the Kirby series a little more representation; maybe in the form of some of the items and/or a modified stage to fit the other characters.
