A Missile Block in Metroid: Samus Returns.

Missile Blocks are a type of destructible block that appear in Metroid Fusion, Metroid: Zero Mission, Metroid: Samus Returns, and Metroid Dread. Missiles can destroy them, as can Super Missiles and the shock waves from Diffusion Missiles. Missile Blocks appear identical to other blocks around them, unless uncovered by a Morph Ball Bomb or Power Bomb; these exposed blocks are then marked with a Missile icon, making their weakness easy to identify.

A direct predecessor to Missile Blocks, although never outright referred to as such, appears in Phase 7 in Metroid II: Return of Samus. The entrance to the area is blocked by a barrier of two large rocks, which are unaffected by Beams and Bombs. When shot with a Missile, the rocks are sent flying and smash to pieces upon hitting the ground. They remain permanently destroyed and do not respawn. These are the only two blocks of this type in the entire game.

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. Furthermore, Super Missiles can destroy these blocks if Missiles are not accessible. Additionally, Metroid: Other M features obstacles that can only be destroyed with Missiles; Search View identifies these obstacles with a Missile icon in a similar manner to revealed Missile Blocks in the 2D games.
