Luigi's Mansion

Luigi's Mansion (, Luigi Mansion) is a stage in Super Smash Bros. Brawl,, and Super Smash Bros. Ultimate. In both Brawl and Ultimate, Luigi is fought here for his unlocking battle.

Stage overview
The characters battle on a downsized version of the mansion that appeared in Luigi's Mansion. The mansion's interior rooms will be visible when the characters pass through the mansion's outer walls; similarly, when all of the fighters are outside of the mansion, the mansion's exterior is shown, although this is only if all four quadrants of the building are still intact. By attacking the support pillars, the mansion crumbles section by section until it is all gone. Due to its supernatural origins, though, it will rebuild itself back to its original status after a while. Unlike the destructible towers on Shadow Moses Island, it is impossible to destroy a quarter of the stage if another is on top of it.

As the pillars are able to be attacked, projectile users can have problems hitting enemies when they are on either side of them (there are some exceptions like 's Robo Beam). 's Raptor Boost, 's Green Missile, 's Quick Draw, 's Skull Bash, and 's Rollout can also can have problems because of this. Players can also use this to their advantage as refuge from such attacks. Notably, the bottom pillars can only be broken if their corresponding upper pillar is broken first; a bottom pillar still has an active hurtbox, but can never be broken unless its top pillar is broken first.

Important properties of the stage are that the mansion provides three levels to brawl on: the ground floor, the second floor and the roof. The roof is the only plain that can be jumped and dropped through - with the exception of a small piece in the center, the middle level has a thickened floor which cannot be penetrated by characters, attacks or items. When the mansion is broken apart completely, the stage layout distinctly resembles, with the addition of two minuscule platforms on either side. The platforms rise and fall alternately, much like the ones featured in the Stage Builder, but they can disappear and reappear at random. It is also impossible to glide underneath the stage because the mansion is on top of a small pillar.

When playing this stage with more than four players or turning off hazards in Super Smash Bros. Ultimate, the pillars lose their hitboxes, rendering the mansion impossible to demolish. This also provides more freedom for projectile users and characters with rushing moves as the pillars no longer hamper these attacks.

In Super Smash Bros. 4, Star KOs are disabled in this stage since their victims would be obscured.

Ω forms and Battlefield form
In Super Smash Bros. for Wii U, the Ω form is set on the roof of the mansion. Its interior is no longer accessible, thus, it can no longer be destroyed. Star KOs can occur here, and the stage extends below the blast line.

In Super Smash Bros. Ultimate, the Ω form and Battlefield form are identical to SSB4's Ω form; however, the stage no longer extends below the blast line and the main platform is resized and reshaped to match and, respectively. The three soft platforms of the Battlefield form resemble the soft platforms of the regular form.

Origin
This stage is based on the mansion in , which suspiciously won in a contest he never participated in. Upon visiting the mansion, he discovers that it is overrun by ghosts, so he must get rid of them with the. The mansion is made up of many different rooms, five of which appear in this stage:

The front door of the mansion leads into the Foyer, making it the first room Luigi enters. The ground floor has one door that leads into the and two staircases that lead to the second floor. On the second floor, there is a door on the left side of the room that leads to a separate hallway. In this stage, the Foyer is the middle room and looks similar to how it originally appeared; however, the door on the second floor is not there.

The Study is the room where Luigi encounters the first, , located on the second floor on the left side of the mansion. In this stage, the Study is the room on the top right, and its design is similar to how it appeared in Luigi's Mansion.

The Nursery is where the first boss,, is located. This room is located in the same hallway as the Study. The room in this stage is on the top left and looks similar to how it originally appeared.

This room is where the Portrait Ghosts are located. The room is large and has a portrait on the back wall along with spinning checkerboard pattern floors. A replica of the same portrait can also be seen in the Parlor. It is located on the first floor on the right side of the mansion. In this stage, the Ball Room is the room on the bottom right and is much smaller than it originally was. The design of the floor in Brawl and Smash 4 is also different than how it appeared in Luigi's Mansion; however, the floor in Ultimate was changed to resemble its appearance in Luigi's Mansion.

This room is located on the first floor on the left side of the mansion. Luigi enters this room after capturing the Portrait Ghost, allowing him to obtain the Water Elemental Medal for the Poltergust 3000. In this stage, the room is on the bottom left and appears very similar to how it originally appeared.

Outside
Outside the mansion, tombstones and wilted trees can be found. In the behind the mansion, there is a well where Luigi discovers that  is trapped inside a portrait. In this stage, tombstones, wilted trees, and a well can be seen in the foreground in front of the mansion.

Super Smash Bros. Brawl
In Brawl tournaments, Luigi's Mansion has progressively become a banned stage. This is due to its walls which prevent opponents from DIing out of certain multi-hit moves and, as they are solid from all directions, create relevant caves of life and introduce the potential for circle camping. The columns also stop projectiles, limiting approach options for characters which rely on them.

When it was legal in more areas, Luigi's Mansion was considered to be one of the best stages for (due to Olimar being able to survive much longer than normal and use up smashes as well as techs),  (due to being able to use down smash and Robo Beam better), and  (due to being able to survive long helping the Aura property). It was also one of the top stages and one of the best  and  counterpick stages.

This stage used to be a major counterpick on the West Coast and in the Midwest, while it was banned on the East Coast. Its potential for circle camping also led to it being banned more often than being a counterpick in tournaments. It is currently banned on a near-universal level at serious tournaments.

Super Smash Bros. 4
In SSB4 Luigi's Mansion was never legal in tournaments for the same reasons as with Brawl, and this remains true as of the 2017 recommended ruleset.

Trivia

 * As shown in a early screenshot of Brawl, the music called Castle/Boss Fortress (Super Mario World/SMB3) was originally intended to be played on Delfino Plaza. The track was moved to Luigi's Mansion for the final version of the game.
 * In Brawl and, there is a face of a Boo underneath the crib in the Nursery. However, it can only be seen with a hacked camera. The texture itself (pictured) seems identical to the one found on a Boo Ball in the original Luigi's Mansion, and is absent from the Ultimate version.
 * Even though the Foyer's second floor has two doors, they lead to nowhere, because the next rooms don't have doors. Also, in the original Luigi's Mansion, the Foyer's second floor has one door that's on the left. The Brawl version has two doors.
 * Luigi's Mansion, Halberd, and Pirate Ship are the only stages to have their own trophy in Brawl.
 * In Ultimate, the following Assist Trophies can only appear on the Battlefield and Omega forms of this stage: Chain Chomp, Mother Brain, Tiki, Kapp'n, Devil, Dr. Wright, Arcade Bunny, and Rathalos. The Moon, Nightmare, Andross, Nikki (due to the dark background obscuring her drawings), and the Squid Sisters cannot be summoned on this stage at all. Additionally, the following Poké Ball Pokémon can only be summoned on the stage's Battlefield and Omega forms: Alolan Exeggutor, Solgaleo and Lunala. Lugia cannot be summoned here at all.
 * Despite this, the website shows Lunala on the stage.
