Paralyzer
From the Super Mario Wiki
Paralyzer is a Special Move that is used by Zero Suit Samus in Super Smash Bros. Brawl. When used, Samus will fire an electric ray from her gun, which will paralyze players who get hit. When this happens, the opponent will be stunned in one spot, allowing Zero Suit Samus to attack or run away. It can also be used to stop an opponents attack. If Zero Suit Samus charges the gun a bit more, the opponent will be stunned longer. If the player does a down smash with this move, she will fire at the opponents feet. Paralyzer is also used by Kirby if he has copied Zero Suit Samus' power.
