Super Missile

The Super Missile is a weapon sometimes found in the Metroid series.

In 2-D Metroid games
In Metroid: Zero Mission and Super Metroid, the Super Missile is acquired by collecting a Super Missile Tank and is used much like a regular Missile. It is much more powerful than a standard Missile and can open both green doors and red doors (which require five regular Missiles in Super Metroid) in one shot and destroy Super Missile Blocks. In Zero Mission and Super Metroid, the Super Missile has a separate set of ammunition that had to be selected, but the expansion numbers between the two games differ; in Super Metroid, Samus gains five Super Missiles when she obtains an expansion, whereas in Metroid: Zero Mission, she only gain two missiles per expansion. In Super Metroid, the Super Missiles move much more quickly than normal Missiles, and do not need time to accelerate in order to gain speed. The appearance of the Super Missile in these games differs from the design of the regular Missile. While the regular Missile has a streamlined rocket-like shape with a small red or pink warhead at the tip, the Super Missile has a much more cylindrical shape with a ring around the midsection and a very large green warhead at the tip.

The Metroid Fusion Super Missile is gained from a Data Room upgrade. These Super Missiles completely overwrite the initial Missile upgrade, meaning ammunition can be gained from the same Missile pick-ups. They have triple the firepower of regular Missiles and have the ability to destroy purple Geron on the Biologic Space Laboratories research station. They highly resemble the original Power Suit Missiles, gaining a purple tip and more pronounced prongs than those from the initial Missile upgrade. These Super Missiles also release a larger amount of exhaust from their propulsion when they are flying and have a larger explosion upon detonation. The later Diffusion Missile upgrade changes the appearance of the Fusion Suit's missiles to highly resemble the original Power Suit Super Missiles. The SA-X, in its first appearance, used a Super Missile to completely destroy a door, indicating that the firepower of a Super Missile is fully capable of destroying Grey Hatches (Security Level 0).

In the Metroid Prime Trilogy
In the Prime Series, the Super Missile is the most frequently used Charge Combo and is usually the first one to be claimed. The Super Missile is used to defeat certain enemies, destroy Cordite in Metroid Prime, and to open Green Blast Shields in Metroid Prime 2: Echoes. In both games, the Super Missile Charge Combo is required to complete the game. It is obtained in the Observatory in Metroid Prime, while the combo is obtained by defeating 8 Space Pirates in the Torvus Temple in Metroid Prime 2: Echoes''.

The Super Missile is fired by charging up a shot from the Power Beam and then simultaneously firing a Missile. The Super Missile would then launch, and if the lock-on targeting system was currently in use, it would home in onto the current target. The Super Missile uses up 5 missiles each blast, so it is to be used sparingly, though some enemies can only be taken down by the Super Missile.

While not explicitly named "Super Missiles", in Metroid Prime Hunters Missiles can be charged in order to fire a single, more powerful Missile with limited homing ability.

The Super Missile is replaced by the Hyper Missile in Metroid Prime 3: Corruption.

In Metroid: Other M
The Super Missile makes a comeback yet again in Metroid: Other M. Of course, its lethal powers are used to destroy certain objects and damage specific enemies. It works similar to the Charge Combo variant from the Prime series; using a mix of the Charge Beam and five Missiles.

When the Seeker Missiles are gained, a Super Missile must be charged in order to fire them.

The Super Missiles are used during the battle with Ridley, Nightmare, and the Queen Metroid in order to damage specific events of them.

It is authorized for use by Adam while in Pyrosphere when Samus is under attack by an unviewable flying fire-breathing creature, and orders her to release the lava flow which is guarded by a Super Missile hatch.

Super Smash Bros.
In Super Smash Bros. Melee and Super Smash Bros. Brawl, Samus can fire Super Missiles by using her Forward+B attack as a Smash attack. Super Missiles are more powerful and move a lot faster, but they cannot home in on opponents like regular Missiles can.

In Melee, the two Missile types are identical in appearance, but Brawl redesigns the Super Missile into its traditional green-tipped shape.
