Gaur Plain

Gaur Plain (, Gaur Plain) is a stage in both versions of Super Smash Bros. 4 and in Super Smash Bros. Ultimate, based on an area from Xenoblade Chronicles. is fought here for his unlock battle in Ultimate.

Stage overview
There are two main rock platforms high up on each side of the stage with walk-off edges, with a giant chasm in between. A collection of smaller and mostly soft platforms appear below the main platforms, with the exact layout changing between the two versions of the game; the Wii U version of the stage also features, near the bottom, some more soft platforms and hard platforms with springs on them: characters can use the springs to bounce up to the top platforms. The Wii U version also has an extra soft platform on the upper left side, below the main platform.

In the 3DS version, the top blast line is very close to the stage, while in the Wii U version it is much further away. The side blast lines are also much closer to the platforms compared to the Wii U version.

The background shifts through a day/night cycle. In and Super Smash Bros. Ultimate only, there's a chance that Metal Face will appear at night, attacking the players with his claws and laser beams. His laser beam attack can target any of the two upper platforms, making them fall and destroying the platforms underneath. The original layout is automatically restored some time after he is defeated. If attacked enough, Metal Face can be defeated, causing him to explode; the explosion harms all characters in its range except for the one who landed the finishing hit. However, he may return when night falls again.

Ω forms and Battlefield form
In Super Smash Bros. 4, the Ω form is set on a rocky platform that is completely flat with a pillar at the bottom that extends below the blast line, which is solid in the Super Smash Bros. for Wii U version but just part of the background in Super Smash Bros. for Nintendo 3DS. Metal Face, springs, and walk-offs are removed, but the day/night cycle still occurs.

In Super Smash Bros. Ultimate, the main platform of the Ω form and Battlefield form is similar to SSB4's Ω forms; however, it is resized and reshaped to match and, respectively. The three soft platforms of the Battlefield form are metallic and are unique to this form.

Hazards Off
With hazards turned off in Ultimate, the springs are absent and Metal Face does not appear. This is reminiscent of the stage's design in for 3DS, though the platforms not in that version are still present.

Origin
In , is a location within the greater Bionis' Leg area. It is a lush, large plain featuring bodies of water and several peculiarly shaped rock formations. Shulk and his friend traverse it in their path to the Bionis' Head. In Xenoblade Chronicles, the plain is much closer to the Bionis' knee than in SSB4.

The gigantic figure seen in the distance is the Mechonis, the other of the two gigantic beings which make up the world in Xenoblade Chronicles. It is visible from Gaur Plain in the original game, but, due to the aforementioned position change, in this stage it appears to be farther away.

Tournament legality
While the Ω form of this stage is allowed, the standard stage is banned from tournaments due to it being very open, allowing for camping. Metal Face disrupts and even destroys the stage occasionally in the Wii U version. The stage also has walk-offs.

Trivia

 * Out of all of the shared stages in Super Smash Bros. 4, Gaur Plain is one of two stages (the other being Wily Castle) that has different gameplay elements between the two versions and is the only stage that has a noticeable difference between the 3DS and Wii U in its stage layout. The 3DS version of Gaur Plain has more condensed blast zones and has several platforms missing from the lower part of the stage, as well as one missing on the left side.
 * In Ultimate, the following Assist Trophies cannot appear on this stage: the Moon, Nightmare, Devil, Nikki and the Squid Sisters. Additionally, the following Poké Ball Pokémon cannot be summoned: Abra, Alolan Exeggutor, Lugia, Metagross, Inkay and Marshadow.
 * In the 11.0.0 update in Ultimate, the default My Music settings for the stage were reorganized; all songs from Xenoblade Chronicles 2 had their default priority lowered to zero, while all other Xenoblade Chronicles songs had their priority raised. The default "alternate" song was also changed from ' to ', making it the only stage to change one of its default songs in an update. This is due to the added Cloud Sea of Alrest stage prioritizing Xenoblade Chronicles 2 songs.
