A {{s|metroidwiki|Chozo Statue}} on the main platform comes to life and briefly walks before settling down into its original position, much like the Torizo in ''Super Metroid''; it does not move in ''[[Super Smash Bros. for Nintendo 3DS]]''. There is a large brain-like organism in the far background that shakes constantly, though it is not based upon any specific creature from the ''Metroid'' series.

A few [[Nintendog]]s or a calico cat can appear as background characters in this stage.

[[Mii]]s appear on this stage, flying through the sky riding jetpacks. Unlike most Mii appearances, these Miis are pre-modeled and do not use the faces of Miis from the player's system.

{{s|mariowiki|Lubba}}, along with several other Lumas, appears on {{s|mariowiki|Starship Mario}} in the background.

A {{s|mariowiki|Blue Toad}} can be seen filming the race from a cliff in the background.

Gracie, Dr. Shrunk, Lloid, and Redd can be seen in the City variation, while Wendell, Pelly, and Sahara can be seen in the village variation.

{{s|zeldawiki|Loftwing}}s can be seen flying around.

Crowds of [[Mii]]s can be seen watching the fight in various sections of the stage, such as Sugarsand Beach, Wishing Fountain and Swordplay Colosseum. Additionally, a single Mii playing frisbee with their dog can be seen on Sugarsand Beach, while at the boating gate it is possible to see a bunch of Miis competing in a water scooter race.

The members of the {{iw|mariowiki|band|Super Mario Odyssey}}, including [[Pauline]], appear on floating platforms, and on the ground in front of City Hall. Interacting with the band members causes them to begin performing "{{s|mariowiki|Jump Up, Super Star!}}" or "Ground Theme (Band Performance)". {{s|mariowiki|Captain Toad}} and the {{s|mariowiki|Odyssey}} can be seen in the background as well.

The {{s|zeldawiki|Old Man}} from ''The Legend of Zelda: Breath of the Wild'' periodically floats onto the stage on his Paraglider.

[[Judd]] and {{s|inkipedia|Li'l Judd}} appear on the stage, indicating who is in the lead by holding up a flag that corresponds to the player's color.

Shadows of [[Dracula]] and [[wikipedia:Akumajō Special: Boku Dracula-kun|Kid Dracula]] appear occasionally, illuminated by flashes of lightning. Other enemies make an appearance, each with an entrance based on how they appeared during their original boss battle in the ''Castlevania'' series: the Creature with Flea Man, Mummy, Medusa Head, Werewolf, Carmilla, and Death. With the exceptions of Dracula and Kid Dracula, all Dracula's Castle background characters received new original artwork for {{b|Spirits|menu}} mode in ''Ultimate''.

Numerous {{iw|arms|fans}} can be seen on the stands of Spring Stadium, similarly to how they appear in ''ARMS''. While they appear to be [[Min Min]] fans, they sport a slightly different attire than they do in the original game, with ''Super Smash Bros.'' themed shirts and caps instead of shirts with Min Min's emblem and her signature beanie.

 

Additionally, a jumbotron on the stadium displays promotional images for all the 15 playable fighters in ''ARMS''. However, the characters themselves do not make a physical appearance on the stage.

One pair of characters will randomly be selected to appear during the match, appearing as a Driver and Blade pair. These pairs include Nia and Dromarch, Tora and Poppi α, Mòrag and Brighid, and Zeke and Pandoria. The selected pair can be in one of three locations, being either to the left, the front or on top of Rex's house, either standing together in one spot or apart in multiple spots. They will perform various actions taken from their idle animations in ''Xenoblade Chronicles 2''. Additionally, several Titans will appear in the background, which includes Goldmouth (the Argentum Titan) with the Maelstrom following behind, Gormott, Uraya, Mor Ardain, Genbu, and Indol. All six Titans will appear in a random preselected order; after all have appeared the cycle repeats for the rest of the match.  

*So far, [[Northern Cave]] is the only non-''Smash'' original new stage in ''[[Super Smash Bros. Ultimate]]'' that does not feature at least one background character.
