Cloud Sea of Alrest
Cloud Sea of Alrest (アレストの雲海, Sea of Clouds in Alrest) is a stage in Super Smash Bros. Ultimate based on Xenoblade Chronicles 2. It is bundled with Pyra and 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. 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'd, Self-destructs and when a Titan appears in the background. He also possesses unique lines for Pyra and Mythra if they are present in the match.
Occasionally, the following Titans will appear in the background:
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 following characters appear as cameos in the background, with one Driver and Blade pair being randomly selected:
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.
Ω form and Battlefield form
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 Final Destination and Battlefield, respectively. Additionally, the character cameos do not appear; however, the Titans still appear in the background.
With hazards off, Azurda's head does not move at all, staying at the starting position throughout the match.
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.
While the stage is a home stage for Pyra/Mythra and Shulk, they 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).
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.
