Grapple Beam
From Wikitroid, the Metroid wiki
The Grapple Beam was one of Samus Aran's many weapons. It first appeared in Super Metroid. The Grapple Beam was used to latch onto certain surfaces, giving Samus some new maneuvers such as swinging from the ceiling. Notably, the Grapple Beam can be used to kill Draygon quickly by grabbing one of the electrified surfaces while in the grip of the boss.
Since Super Metroid, the Grapple Beam has appeared in Super Smash Bros., Super Smash Bros. Melee and Super Smash Bros. Brawl as Samus' throw.
It has also appeared in Metroid Prime, where the Grapple Beam was primarily used to get across long distances. The Grapple Beam didn't have much difference in Metroid Prime 2: Echoes, while Metroid Prime 3: Corruption uses it to pull barriers from doors and shields from Pirates (Grapple Lasso), and later on, siphon and feed energy to and
In Metroid Prime 3: Corruption, there are four Grapple Beam related powerups:
Somewhat notably, in all of the 3D Metroid games, the grapple beam was no longer fired from the Arm Cannon. Instead, a glove of sorts was used. This is likely to make it more real-looking. Swinging from the Arm Cannon would seem to cause sprains in the wrist, and maybe even break it due to having the ability to pivot the wrist restricted.
[edit] Note
The Grapple Swing is the game's name for the traditional Grapple Beam power-up, except in Corruption, where it is a seperate power up that allows Samus to swing from Grapple Points.
Samus Aran's gunship also gains a Grapple Beam towing cable power-up, that gives Samus the ability to transport various large objects by having her Gunship fly in and grapple them via ship-mounted Grapple Beam.
