Seeker Missile

From Wikitroid, the Metroid wiki

The Seeker Missile, rather than empowering individual missiles, allows Samus Aran to simultaneously fire up to five missiles at up to five distinct targets, or to fire five missiles at the same target in one burst by charging her missiles. Using the Seeker Missile is a must to pass some of the puzzles in Metroid Prime 2: Echoes, though it is rarely necessary for combat.

Samus is also able to obtain the Seeker Missiles in Metroid Prime 3: Corruption. This time, they appear to be the result of Space Pirate research as they are obtained in a Space Pirate lab on SkyTown. They can harm Helios in his disc form and are used to open doors and locks on Skytown primarily by destroying several locks simultaneously.
