'''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]].

The stage takes place on top of [[Azurda]] (also known as Gramps), serving as the home of [[Rex]] in ''Xenoblade Chronicles 2''. The stage continuously floats through the skies as other titans fly by. 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. Throughout the battle, Azurda will provide banter and comment on the state of the battle. When the battle starts, gramps will say "I want to see a good clean fight, do you hear?" Other examples include when a figher is [[KO|KO'd]] 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:

*Argentum, with the Maelstrom following behind

Additionally, the lighting and color scheme of the background changes as the titans appear.

*Nia and Dromarch

They can appear either next to or on top of Rex's house.

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 general aesthetic of the stage comes from the beginning of ''Xenoblade Chronicles 2'', when [[Rex]] lives on the back of Azurda and they swim around the Cloud Sea in search of salvaging opportunities. The titans and other entities spotted in the background are all areas that can be explored in the game. The various background characters that appear on the stage are party members that Rex befriends throughout the game.

Due to its recent release and the ongoing COVID-19 pandemic, the legality of this stage is not fully decided, as Azurda's head does not move with hazards off.

*Sakurai stated that the reason why Azurda is not the main platform for the Ω and Battlefield forms is because the development team thought he would be "crushed into jelly" if they tried to make him the same size as Battlefield.

*Like [[Pyra]]'s fighter model and [[Mythra]], 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.

*The World Tree, a location in the original game, can be found at the beginning of the stage, when moving the camera to the left side. This applies to both its default form and its Ω and Battlefield forms.
