'''Cloud Sea of Alrest''' ({{ja|アレストの雲海|Aresuto no unkai}}, ''Sea of Clouds in Alrest'') is a stage in ''[[Super Smash Bros. Ultimate]]'' based on ''Xenoblade Chronicles 2''. It is bundled with {{SSBU|Pyra}} and {{SSBU|Mythra}} in Challenger Pack 9, which is also part of the [[Fighters Pass Vol. 2]]. It was released on March 4th, 2021.

The fighters battle on top of [[Azurda]] (also known as Gramps), serving as the home of [[Rex]] in ''Xenoblade Chronicles 2''. Azurda continuously floats through the skies as other Titans fly by. The entire stage has a gentle sway that slightly changes the altitudes of platforms. There is a single floating platform on the left end of the stage, and Azurda's neck acts as a mild slope on the right side. Occasionally, Gramps will raise and lower his head, which will affect the angle of the slope. He will also turn his head to look at the Titans, which temporarily shrinks the size of the stage. The stage contains indications for when he is about to turn his head, such as his neck shaking, a windmill spinning faster than usual, and the door to Rex's house closing. If there are fighters standing on Azurda's head or hanging from his horn when he turns his head, they will slide inwards rather than fall off. Throughout the battle, Azurda will provide banter and comment on the state of the battle. When the battle starts, Azurda will say "I want to see a good, clean fight. Do you hear?" When a player is down to one stock, Azurda will say "It seems that we will soon have a winner!" Other examples include when a fighter is [[KO|KO'd]], [[Self-destruct|Self-destructs]] and when a Titan appears in the background. He also possesses unique lines for {{SSBU|Pyra}} and {{SSBU|Mythra}} if they are present in the match.

Occasionally, the following Titans will appear in the background:

*Goldmouth, the Argentum Titan, with the Maelstrom following behind

The order the Titans appear is randomly selected at the start of the match; once all six have appeared the cycle repeats in the same order. Additionally, the lighting and color scheme of the background changes as the Titans appear. The World Tree will also occasionally appear in the background.

They can appear either in front, to the side or on top of Rex's house, standing either together in one spot or standing apart in two different spots. However, they will not appear in matches with five or more players.

The main platform of the [[Ω form]] and [[Battlefield form]] does not feature Azurda as the main platform, but instead uses a haphazardly constructed airship that matches the size of {{SSBU|Final Destination}} and {{SSBU|Battlefield}}, respectively. Additionally, the character cameos do not appear; however, the Titans still appear in the background.

The layout of the stage comes from the beginning of ''Xenoblade Chronicles 2'', where [[Rex]] lives on Azurda's Back as they swim across the Cloud Sea in search of salvaging jobs. The Titans spotted in the background are all areas that can be explored in the game. The background characters that appear on the stage are party members that Rex befriends throughout the story's events.

 

While this stage is a home stage for {{SSBU|Pyra}}/{{SSBU|Mythra}} and {{SSBU|Shulk}}, the latter can only be present at the beginning of ''Xenoblade Chronicles 2'' during a New Game+, as Rex loses Azurda as a home before encountering Pyra, with Azurda regenerating into a small larval stage for most of the game. Although Azurda regenerates into his adult form at the end of the game, Rex's house on his back no longer exists. Rex's fellow party members cannot be present on Azurda's Titan form at all until the very end of the game, as they do not appear at the start of a New Game+, unlike Pyra/Mythra and other Blades previously unlocked (including Shulk).

Cloud Sea of Alrest has been banned from tournaments due to the large slope on Azurda’s neck creating unusual, potentially disruptive geography. The lower blast zone somewhat obscures characters that are inside the cloud sea.

*Like with [[Pyra]]'s fighter model and [[Mythra]]'s appearance in ''Smash'' as a whole, Brighid's outfit as a background character has been modified from ''Xenoblade Chronicles 2'' due to ''Ultimate''{{'}}s lower age rating, covering up her midriff and legs. However, she remains uncensored in "cutscene" footage in Pyra and Mythra's reveal trailer.
