Hammers are items commonly used as weapons throughout the Mario series. They first appear in Donkey Kong, in which they are used to smash Barrels and enemies. Hammers are usually thrown by the Hammer Bros. and other enemies. However, Mario and Luigi, the heroes of the Mushroom Kingdom, have been known to effectively wield Hammers in combat. In the Paper Mario and Mario & Luigi games, Hammer attacks are used as a counterpart to Jump attacks. Some enemies cannot be damaged by Jump attacks, requiring the Mario Bros. to use their Hammers instead.
 Donkey Kong
In Donkey Kong, the original arcade game, Mario can destroy the barrels thrown by Donkey Kong, Fires created from the flaming Oil Drums, and Sand Piles in 50m. Mario is not invincible when using it, however. If attacked from the back, he will still lose a life. Mario also cannot climb or jump while wielding the Hammer. Hammers in this game can be found usually in the corners and some can only be reached by jumping.
In Donkey Kong for the Game Boy, Hammers make a reappearance. They can be used to defeat all enemies in the game. Super Hammers can even break brick walls. In this game, Mario can throw Hammers upwards. At several points in the game, the player has to throw the Hammer upwards, then quickly climb the ladder onto the next platform above to pick it up again. If the Hammer touches a floor, it disappears instantly.
 Super Mario series
Super Mario Bros. shows the Hammer being used by Hammer Bros. These Hammers are extremely hard to dodge, especially when the Hammer Bro. appears in pairs. They seem to have an unlimited supply of Hammers, just like Lakitus and their Spiny Eggs. However, the Hammer Bros. are not the only ones able to wield Hammers in this game. Bowser can throw a flurry of difficult to dodge Hammers, but only in the later worlds. The Hammer from Donkey Kong returns in Super Mario Bros. Special. Mario and Luigi can wield an unlimited supply of Hammers by donning the Hammer Bros.' Suit in Super Mario Bros. 3. When wearing the suit, they gain all the characteristics and abilities of the Hammer Bro., also giving them fire immunity. These suits start appearing in World 6, and can only be found in Toad Houses and the same type of Giant ? Block which houses the Frog and Tanooki Suits.
Hammers are also used in Super Mario Bros. 3 as a map screen item to destroy boulders preventing access to hidden areas. Usually, a Hammer just allows Mario to produce a quicker route, but in some cases, it is the only way to access a part of a map. In Desert Hill there is a section in the upper right corner that leads to an area that contains a Toad House with a Frog Suit, and a Fire Bro. battle containing the last Warp Whistle. In Water Land, there is a section leading to a canoe ride which takes Mario or Luigi to several Toad Houses and Spade Panels.
 Club Nintendo
Mario repeatedly used a Hammer in the German Club Nintendo comics. In 1994 "Super Mario: Verloren in der Zeit", he smashes his alarm clock (due to his dream in which there was an alarm clock-looking Time Machine). Later, in the 1995 comic "Mario's Picross", Mario makes a more effective use of a Hammer when he smashes the wall in a Pyramid, after reaching a dead end. While in the first comic the tool looks a lot like a regular Hammer, it resembles a Super Hammer in the latter.
 Super Mario RPG: Legend of the Seven Stars
In Super Mario RPG: Legend of the Seven Stars, Mario's first and weakest weapon is called the Hammer. After Mario beat the Hammer Bros. blocking the exit of Mushroom Way, Mario receives a Hammer apparently dropped by them with the Hammer Bros. insignia on it. The plumber uses this weapon to pound enemies, at least until he finds the Nok Nok Shell. When equipped, the weapon adds ten attack points to Mario's attack rating. When Mario uses it with the Timed Hit, he swings it up and down twice, similar to the old style. Later on in the game, he finds more advanced Hammers: the Super Hammer, Masher and the Ultra Hammer, along with another Hammer with an added effect.
 Paper Mario series
In Paper Mario and Paper Mario: The Thousand-Year Door, Mario receives not only the Hammer, but the Super Hammer and Ultra Hammer as he progresses through the adventure. He can use Hammers to knock items out of trees. Paper Mario and Paper Mario: The Thousand-Year Door give the Hammer much more focus and is the only way to defeat certain enemies. In battle, Jump attacks can not work on every single enemy, so the Hammer is introduced as an alternative. It works on all enemies and is always stacked damage, proving useful against fire, spiked, and high defense enemies. There is one flaw to it though; it does not work against air-bound and ceiling attached enemies. With a special badge, namely Hammer Throw, it can be used on all enemies.
Outside of battle, the Hammer can be used to break certain Blocks. The type of block Mario can break depended on what type of Hammer he had. In Paper Mario, Yellow Blocks can be broken by any Hammer, Stone Blocks by the Super Hammer and Ultra Hammer and Metal Blocks by only Ultra Hammer. In Paper Mario: The Thousand Year Door, small yellow blocks can be broken by any Hammer, big yellow blocks by the Super Hammer and Ultra Hammer, and stone blocks (big and small) by only the Ultra Hammer. Metal block can't be broken by any Hammer in the latter game. The move, Spin Hammer is also introduced in Paper Mario: The Thousand-Year Door as a way to destroy even bigger blocks. However, the Red Block is removed from Paper Mario: The Thousand-Year Door. In Paper Mario it is given by Goompa after finding him and his Hammer lost in the bushes. Jr. Troopa is the first one lucky enough to be tested on. In Paper Mario: The Thousand-Year Door it is a default weapon and it is degraded again into a normal Hammer. The first Hammers in this series are wooden.
In Paper Mario: Sticker Star, multiple Hammer stickers can be found throughout the game. While Mario can still use his hammer within the overworld, there are a variety of Hammer stickers found in the game, including:
Concerning the overworld hammer, Mario obtains this at the beginning of the game, after recovering from Bowser's attack on Decalburg. In World 3-7, Rustle Burrow, Mario loses his overworld hammer; as such, he is unable to use Hammer stickers in battle.
 Mario & Luigi series
The Hammer is used by the Mario Bros. in Mario & Luigi: Superstar Saga, Mario & Luigi: Partners in Time and Mario and Luigi: Bowser's Inside Story. However, this move is not used as much compared to the Paper Mario series. Unlike the Paper Mario series battle system, each Hammer upgrade do not affect in-battle damage and attack power.
In Mario & Luigi: Superstar Saga, Hammers are crafted by the Hammerhead Bros. out of Hoohoo Blocks. They are used to smash rocks (instead of blocks) in Mario and Luigi's path, defeat enemies in battle, and hit special buttons and switches. If used on an enemy in the overworld, its party will be stunned at beginning of the battle. They can later be upgraded to Super Hammer and, ultimately, Ultra Hammer. After Cork and Cask teach them the advanced method of using the Hammer they can use various overworld and battle abilities.
To do more damage in battle, Mario or Luigi must press their button when the hammer shakes.
In Mario & Luigi: Partners in Time, two Hammers are given to Baby Mario and Baby Luigi by the L33t Hamm3r Broz. These weapons can be used to tunnel underground (a useful technique when searching for Beans) and hit switches. In battle, Baby Mario and Baby Luigi can use their Hammers to attack enemies (and potentially stun them, rendering a monster inactive for a few turns). Unlike the other Mario RPGs, these Hammers serve their purpose for the entire game and are never upgraded.
The action command for the hammer is the same: press the button when it shakes. If the babies battled with the Mario Bros., The adult bro must press their button to lift up the baby, then press their baby button.
In Mario & Luigi: Bowser's Inside Story, Mario and Luigi gain Hammers much earlier than in the other Mario and Luigi games. Mario and Luigi find Hammers in the Trash Pit. Later, Luigi learns how to turn Mario into Mini Mario by using his Hammer in Pump Works.
Hammers in battle are used quite differently. Mario or Luigi must press their button at the very last moment before the hammerhead falls. Doing so gives the player an "Excellent".
 Mario vs. Donkey Kong series
 Super Smash Bros. series
The Hammer from Donkey Kong is a powerful item in Super Smash Bros., Super Smash Bros. Melee and Super Smash Bros. Brawl. The player will swing the Hammer back and forth repeatedly, and will strike anything upward in its path. The character cannot double jump with it. Very rarely, in Super Smash Bros. Melee and Super Smash Bros. Brawl, the head of the Hammer will fall off, and the character will swing the stick back and forth, leaving him or her completely vulnerable. However, the head will act as an item, and will have the same power as the regular thrown item. When the Hammer is used, the Hammer theme from the original Donkey Kong arcade game plays. The item returns in Super Smash Bros. Brawl, with the exact same effects. A much stronger variant originating from Wrecking Crew, the Golden Hammer, appears as an item in Super Smash Bros. Brawl as well. Kirby and King Dedede use a hammer attack in the game.
 Mario Party series
In Mario Party 3, Toad uses a hammer as his weapon when a partner.
Hammers are also used in other minigames in Mario Party 1-3.
The hammer is also Hammer Bro.'s signature emblem that appears in Mario Party 8.
Hammers reappear in Mario Party 9 in the minigame, Spike Strike, where players have to defeat the giant Spike using hammers. There is also one golden hammer for each round. If a character uses it, that character will earn three points, while iron ones are worth one. Additionally, when landing on a Battle Space, a Hammer Bro. might appear and it will throw hammers at each off the players, taking away three Mini Stars from each player.
 DK: Jungle Climber
The Hammer in DK: Jungle Climber looks somewhat like a Barrel. Donkey Kong can take it and, with the help of Diddy Kong, use the Hammer to smash barrels, rocks and other solid elements that Donkey Kong cannot break in his own. This item can only be used for a limited time before Diddy Kong drops it.
