Missile Blocks are a type of destructible block that appear in Metroid Fusion and Metroid: Zero Mission. Missile Blocks appear identical to other blocks around them, unless uncovered by a Morph Ball Bomb or Power Bomb. Missiles can destroy them, as can the shock waves from Diffusion Missiles. Though not actually featured in the Prime Series, there is an object of similar nature called Brinstone, which is also weak against Missiles. It is possible that the Blocks are made of the same materials, but it is never specified. Also, Super Missiles can destroy these blocks if Missiles are not accessible.
