Builder Mario

Builder Mario is the form Mario takes in Super Mario Maker 2 after collecting a Super Hammer, a power-up found exclusively in the Super Mario 3D World style. It adds a tool belt and a hardhat, and, in Mario and Luigi's case, changes their attire to yellow shirts and colored overalls. It grants Mario and co. the ability to swing a large hammer to slam the environment and enemies alike. Unlike Hammer Mario, where the hammers are arched projectiles, Builder Mario uses them as a melee weapon. Builder Mario can also create a maximum of five Builder Boxes at a time to be used as platforms.

In Super Mario Odyssey, a cap and outfit based on the Builder Mario appearance (named the Builder Helmet and the Builder Outfit respectively) can be purchased from Crazy Cap stores in Metro Kingdom.

In Super Smash Bros. Ultimate, Builder Mario appears as an alternate costume of Mario.

Abilities
Using the Dash button will make Mario execute a melee attack with his hammer, having a range of about 1 block in front of him and 2 blocks high. This attack is able to destroy Hard Blocks. If the attack is too close to an unbreakable object, such as ground, Mario will bounce back once the attack hits it. When the player holds up, Mario will appear to hold his breath, signalling that he is now able to create a Builder Box. Using the Dash button while holding up will create a Builder Box. Up to 5 Builder Boxes can be made at a time, after which the boxes will disappear as new boxes are created. Builder Boxes are similar to Crates, but they have the player character's emblem on it.

Trivia

 * Builder Mario's design comes from the Wrecking Crew series, where Mario also wears a helmet and attacks with a hammer. The helmet's appearance is similar to the one in Wrecking Crew '98.
