Super Smash Bros. Melee/Samus

Throws
Samus will extend her Grappling Beam and reel her opponent in if the tip connects. It's best to use this while dashing, because the animation is faster.

Bomb jump
A must for Samus players, the bomb jump is one of Samus' best assets. She can use it to get back onto a ledge from extremely long horizontal distances. The technique is executed by repeatedly laying bombs (down + B button) and guiding oneself so that one lands on them and bounces into the air towards the ledge. This is repeated over and over until the player reaches the ledge. A Samus player who has mastered the bomb jump can recover from just about any hit except for a meteor smash or a hit that sends her off the screen instantly.

Missile cancel
The missile cancel is the fastest way to fire missiles. It is performed by firing a power missile just before Samus hits the ground. This cancels out the lag of the missile and allows the player to perform another action (including firing another missile) immediately afterwards.

Super wavedash
This is more of a novelty than a useful technique. It causes Samus to shoot across the screen at a distance almost equivalent to the width of the Final Destination stage. It would be very useful as a form of evasion, but it is very difficult to execute consistently. It is performed by laying a bomb, then, just as Samus hits the ground, smashing the control stick as quickly as possible in the opposite direction the player wants to travel, and then in the direction the player wants to travel. The timing for this technique is extremely precise - it can only be executed in the window of 2 frames.

Extended Grab
Press left and right on the d-pad while tapping Z. You can only grab by pressing Z again and home to the other players by holding R. It may take many tries to get right.
