Miracle Matter is one of the last bosses of the Nintendo 64 video game Kirby 64: The Crystal Shards. 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 it's understandable to assume when fighting Miracle Matter that he is the final boss of the game, 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 its special abilities is to transform into all seven copy powers that Kirby can transform into. To damage Miracle Matter, Kirby would have to suck in oncoming projectiles and shoot them back at the sender.
