Charge Shot
From the Super Mario Wiki
Charge Shot is a special attack used by Samus Aran in the Super Smash Bros. series. It is Samus's normal B Button move. Once done, Samus will hold up her arm, which acts as a blaster, and she will start charging up an Energy Ball. Although the attack can be fired at any time, charging it up makes the attack more powerful. If it is charged up to its maximum, Samus will hold the energy in the blaster, and can walk around with the energy. Then, when the right opportunity arises, the player can press the B Button again to fire the attack. If charged to the most, the attack will usually hold enough power to instantly KO an opponent. The attack was used in Super Smash Bros., Super Smash Bros. Melee, and has been seen in Super Smash Bros. Brawl. Kirby can also use Charge Shot if he has copied Samus's abilities.
