Miracle Matter is one of the last bosses of the Nintendo 64 video game Kirby 64: The Crystal Shards. He is fought on Ripple Star, and his arena takes place in (possibly) the throne room. The tiny protagonist Kirby will be able to take on the beast after collecting every single Crystal Shard that there is to be collected (excluding the final one, which will be obtained after defeating Miracle Matter). At first assuming when Miracle Matter is fought that he is the final boss of the game is understandable, though it'll soon be revealed that another character, known simply as 0², is in fact the true final boss.
Miracle Matter is a white colored character who sports 20 red eyes and 20 faces. One of his special abilities is to transform into all seven copy powers that Kirby can transform into. To damage Miracle Matter, Kirby would have to use his inhale to suck in oncoming projectiles and shoot them back at the sender. The projectiles have to match their respective form in copy ability.
His needle attack bears a resemblance to the Laughing Needle move that Void Termina's core can use. When it does so, it jumps to the centre of the arena and bursts into laughter, unleashing 8 spikes from its body.
In Soul Melter, Void Soul has a similar attack called Full Smile where he splits into four and launches the needles. The needles are rotated 22.5 degrees from their original position. During this attack, Void Soul and his clones share their health bar. The clones will be at the same level as their creator is in Soul Melter EX and the group will shift to attack again.
