Bosses

BRINSTAR

Kraid The giant lizard of Brinstar attacks Samus with thorny projectiles and spits spheres out of its mouth. No weapons -- beams, missiles, or bombs -- have any effect on its body. The creature's weak point is unknown.

(The Mini-Boss)
Spore Spawn This creature was genetically engineered by the space pirates. Its weak point is its core, which is protected by the plant's hard shell.
