0²

0² (also written as 02, Zero Two,[1] or Zero2[2]) is the true main antagonist and final boss of Kirby 64: The Crystal Shards. It resides deep within Dark Star. Rather than taking control of Planet Popstar, Dark Matter invades the equally peaceful home world of the Fairies, Ripple Star. While not seen to be producing Dark Matter forces, 0²'s role as the final boss, as well as the battle's location, suggest that it is the intelligence behind these events. Since Dark Matter's first priority on Ripple Star is the destruction of the Crystal in Ripple Star's palace, it is apparent that Dark Matter and/or 0² knows the Crystal presents at least a credible threat to the plans in motion. It is seen near the end of the game that the reunited Crystal has the capability to purge Dark Matter or related forces from the infected people (the Fairy Queen in this case) with a beam of light and relieve them of its possession without the victim receiving a thorough beating beforehand. Comparatively speaking, the Crystal is to 0² as the Love-Love Stick is to Zero. Playing into the fairly clear light and dark themes the game presents, it suggests Zero, 0² and Dark Matter are weak against light from the Crystal at least, as well as certain positive emotions as suggested by the effects of the Love-Love Stick against Zero previously in Kirby's Dream Land 3.
