Paralyzer

The Paralyzer is Zero Suit Samus's main weapon, capable of only stunning enemies. It made its first appearance in Metroid: Zero Mission.

Super Smash Bros. appearances
In the Super Smash Bros. series, Paralyzer is Zero Suit Samus's standard special move, since her introduction in Super Smash Bros. Brawl. Upon using the move, Zero Suit Samus fires a blast from the gun that can stun opponents. The blast can be charged by holding down the special button, which increases the distance that the blast can travel and the duration of the stun effect.

In Super Smash Bros. for Nintendo 3DS / Wii U, the Paralyzer has two custom variants. The first is Blast Shot, which fires faster and has a greater range, but does not stun and deals less damage. The second is Electromagnetic Net (named Spreading Shot in British English versions), which fires a larger blast that covers a greater range and explodes, dealing continuous damage, but it does not travel as far.

The Paralyzer is also involved in two of Zero Suit Samus's other special moves: the Plasma Whip and, in Super Smash Bros. Brawl, the Plasma Wire. It is also used in her taunts and grab.
