Ultra Hammer

The Ultra Hammer is the strongest variation of the hammer weapon in various Super Mario role-playing games.

Super Mario RPG: Legend of the Seven Stars
The item first appeared in Super Mario RPG: Legend of the Seven Stars. In this game, the Ultra Hammer is Mario's second most powerful weapon, being beaten by the Lazy Shell. It is found in the Factory inside a treasure chest, shortly before fighting Count Down. In the official artwork for the Ultra Hammer, the hammerhead has metal linings on each end and has the word "ULTRA", in red, at the side.

Paper Mario series
In Paper Mario and Paper Mario: The Thousand-Year Door, the Ultra Hammer is Mario's strongest hammer. Upon being collected, it replaces the Super Hammer. In battle, a timed Ultra Hammer attack deals six points of damage to a defenseless enemy without attack-raising badges (while Mario's normal hammer only delivers two, and his Super Hammer only delivers four).

Paper Mario
In Paper Mario, the Ultra Hammer is found within the caverns of Mt. Lavalava, and allows Mario to smash metal blocks. This new ability allows him and Kolorado to delve deeper into the volcano and eventually face the Lava Piranha. It can also be used to flip hidden panels on the ground just like the Super Boots, revealing Star Pieces from underneath.

Paper Mario: The Thousand-Year Door
In Paper Mario: The Thousand-Year Door, the Ultra Hammer is found inside a chest placed on a high platform in Rogueport's plaza that Mario must use the Spring Jump to dislodge it from underneath. This Ultra Hammer has been downgraded somewhat from the previous game in that it can only destroy stone blocks at the most and cannot reveal Star Pieces in the ground.

Like the Super Hammer, the Ultra Hammer can be used to perform a spinning hammer swing, which is capable of destroying large yellow and stone blocks alike, unlike the Super Hammer. It can also be used to get the First Strike on enemies, allowing Mario to start the battle with an Ultra Hammer attack without using any Flower Points. The Ultra Hammer attack in battles costs 4 FP and knocks the front enemy back into any enemies behind it and will always deal 3 damage to enemies attacked behind the front enemy, regardless of attack boosting power-ups and enemy defense. This is a stronger version of the Super Hammer move, which itself is very similar to the Spin Smash move from Paper Mario. Its action command is similar to the normal Hammer action command, but there are nine dots that light up before the star, increasing the time that the Control Stick must be held down.

Mario & Luigi: Superstar Saga / Mario & Luigi: Superstar Saga + Bowser's Minions
In Mario & Luigi: Superstar Saga and its 3DS remake, Mario & Luigi: Superstar Saga + Bowser's Minions, the Ultra Hammer is the third and last Hammer upgrade Mario and Luigi receive. After being tasked by Bowletta with going to Joke's End so the brothers can give her the revived Beanstar, Mario and Luigi can return to the Hammerhead Bros. in their cave in eastern Beanbean Outskirts, who have mastered a "brand-spankin' new hammer makin' technique". The two then continue to reforge Mario and Luigi's Super Hammers into Ultra Hammers using their new technique.

With them, they can break Black Rocks on the field (golden rocks in the remake), most notably giving the duo access to Surfing Spots on the shoreline of Oho Ocean, which are needed to reach their next destination, Joke's End. They also gain access to the second room behind the Hammerhead Bros.' cave, allowing them to have the chance to win the Secret Scroll 2, and with it, the new Bros. Attack, Cyclone Bros. by playing a minigame hosted by a Thwomp. Unlike the Ultra Hammers in the Paper Mario series, these hammers are not any stronger in battle in the original game, but they give higher damage variance. They also lack the red stripe.

Trivia

 * Mario & Luigi: Paper Jam's Trio Attack Hammer resembles the Paper Mario series' version of the Ultra Hammer, except that it reverses the colors and it has a star on its end.
 * The Ultra Hammer's appearance in Paper Mario and Paper Mario: The Thousand-Year Door resembles the Golden Hammer from Wrecking Crew.
 * It also resembles the hammer the character gets hit with when they lose a Game Guy minigame in Mario Party 3.
 * If Popple steals the Ultra Hammer in Mario & Luigi: Superstar Saga, it becomes gray like the Super Hammer. This may be an error.
