The Golden Hammer (ゴルデンハンマー, Golden Hammer) is an item in Super Smash Bros. Brawl and Super Smash Bros. 4. It acts similarly to a regular Hammer, but has its own distinctive properties to make it arguably more formidable in comparison.
As an item
When the item spawns normally, only its podium will appear. A second later, the actual Golden Hammer will grow from it. The hammer cannot actually be picked up until it is fully grown from the podium. When picked up, the Golden Hammer forces players to constantly swing the weapon back and forth, much like the standard hammer. Compared to the standard Hammer, characters wave it back and forth considerably faster, and it also has considerably higher knockback, hitlag, and damage output compared to the Hammer. Its knockback is also diagonal, as opposed to the Hammer's vertical knockback. While characters cannot use any attacks while swinging it, constantly tapping the attack button will cause the player to float in midair.
Like the Hammer, getting hit by attacks that inflict knockback can cause the wielder to drop the Golden Hammer; in addition, it is impossible to manually let go of the Golden Hammer unless the wielder is tumbling. If the Golden Hammer is dropped by its wielder, however, it will immediately disappear upon hitting the ground. Golden Hammers that are dropped can be grabbed by air-dodging players.
Similar to how the Hammer can lose its head, the Golden Hammer also has the chance to backfire on its wielder. Called the Golden Squeaky Hammer, the item still allows players to float, but it does not inflict any damage or knockback to opponents; instead, it produces a squeaking noise upon striking them. Unusually, counters can still activate if hit by the Golden Squeaky Hammer.
Unlocking certain challenges will give players access to Golden Hammers to break other Challenge boxes. Each Golden Hammer can only be used once. Using the Golden Hammer allows the player to attain any rewards from the box, as well as revealing criteria for the two boxes next to it. Players can immediately break open a challenge with a Golden Hammer without having to meet the condition. However, some challenges cannot be broken with the Golden Hammers, particularly difficult challenges, as well those that involve plot elements from the Subspace Emissary. In the PAL version of Brawl, this does not apply, and instead, Golden Hammers can open all challenges.
In Super Smash Bros. Brawl
The Golden Hammer Trophy is obtained by hitting a combined distance of 15,000m (45,000 ft) with all characters' Home-Run Contest records.
A hammer that glows with golden light. It's easier to swing than a normal hammer, and more powerful too. If you tilt the Control Stick and press the attack button repeatedly, you float in midair. It's a very powerful item, but one that rarely appears. There's also a Golden Squeaky Hammer that does absolutely no damage at all. It's what you would call a fake.
In Super Smash Bros. 4
This special hammer is several times stronger than the regular hammer. While wielding it, jumping repeatedly will let you float in the air. It doesn't appear often, so grab it when it does! However, watch out for the squeaky version. It looks like the normal one but is really useless.
This special hammer is much stronger than the normal one. And on top of that, it has a special ability - press the jump button repeatedly while holding it to float in the air. These things don't show up often, though, so if you see one, grab it fast! Just watch out for the Golden Squeaky Hammers - they look the same, but do exactly zero damage.
The Golden Hammer originates from the NES game Wrecking Crew where it is a rare and temporary item that allows the player to swing faster. It is also more powerful than a normal hammer. When the hammer appears, a short tune can be heard, then when the hammer is acquired the Power-Up Music track is played; this track can also play on the Mario Bros. stage.
Contrary to its depiction in the Smash games, the Golden Hammer cannot act "squeaky" in Wrecking Crew or otherwise malfunction.
