void (kirby)
The absolute true form of Void Termina. Ancient texts imply that he is able to reincarnate from positive or negative energy. That along with attacks during his boss fight suggest a heavy connection to, among other things, Dark Matter, Zero, Dark Mind, and even Kirby himself. Defeating it allows the player to swap between Kirby's current appearance and the design he debuted with in Kirby's Dream Land.
Void's most notable trait compared to his previous forms is rainbow veins coursing through his body.
