The Hammer is Kirby's Smash B move, introduced in Super Smash Bros. Melee (as were most Smash B moves). Kirby swings the hammer he gains from his Hammer ability in the Kirby series. On the ground, he swings it horizontally (as opposed to in the games, where he swings it vertically over his head to the ground in front of him), however, in mid-air, he swings it vertically, more like in the games. This is altered in Super Smash Bros. Brawl; while being used in the air, he swings the same way. The grounded version move is much better in Brawl, because it's as fast and has no sweetspot unlike Melee which was tiny and the sourspot was very weak and punishable.
While being used in mid-air, Kirby spins twice instead of once, and the hammer appears to be set aflame, akin to one of Kirby's attacks as Hammer Kirby. He also gains horizontal distance using Hammer. Of the two mid-air swings, the first does mainly vertical knockback and the second has great horizontal knockback. This is particularly useful against bosses like Ridley, as it can stall his fall time, allowing him to use Double Hammer again for a total of four hits. This is capable of taking out up to a third of Master Hand's HP.
In the E3 2006 movie of Brawl, Kirby was seen using the Hammer move in mid-air, using it in the same fashion as in Melee, so the attack must have been modified later in development.
Hammer is one of Kirby's many copied abilities from his various adventures. It has often some of the most powerful ones. It should be noted that Kirby swings the hammer differently than in his games. The hammer is almost identical in appearance to King Dedede's.
