Missile is Samus Aran's side special move introduced in Super Smash Bros. Melee. Samus fires a missile from the Metroid series that can also home in on opponents by slightly angling themselves as they fly, eventually stopping in midair and exploding. By using the attack like one would a Smash Attack, Samus instead fires a Super Missile, a larger and more powerful missile that flies directly forward before automatically exploding.
Super Smash Bros. for Nintendo 3DS / Wii U introduces two custom variations for this move. The first variant is Relentless Missile, which has Samus fire a slower missile that better homes in on opponents; the Super Missiles are also made slower, and do not have as much range. The second variant is Turbo Missile, in which Samus fires missiles that hang in the air for a moment before moving, but move faster and can adjust their angle to home in on enemies before taking off; the hanging property also applies to the Super Missiles.
