Background character
Background characters are cameo characters that appear in a stage that corresponds to their home universe (e.g. King Dedede appears in the Super Smash Bros. stage Dream Land). Note that background characters should not be confused with stage hazards, since background characters do not directly affect gameplay.

Pyoro can occasionally appear in the background of the stage with the blocks from the Bird minigame from Game & Wario, which players can use them as another way to hide from 5-Volt's line of sight. Reporter John can also be seen in the background on the TV while 5-Volt is watching it.

New Donk City Hall
The members of the band, including Pauline, appear on floating platforms, and on the ground in front of City Hall.

Dracula's Castle
Shadows of Dracula and Kid Dracula appear occasionally, illuminated by flashes of lightning. Other boss characters make an appearance, each with an entrance based on how they appeared during their original battle in the Castlevania series: the Creature and his Flea Man ally Igor, a Mummy, Medusa, the Werewolf, Carmilla and Death. With the exceptions of Dracula and Kid Dracula, all Dracula's Castle background characters received new original artwork for Spirits mode in Ultimate.
Mementos
Morgana, as the Morganamobile, will occasionally drive in the background of the stage, dropping off members of the Phantom Thieves of Hearts. These include Ryuji Sakamoto, Ann Takamaki, Yusuke Kitagawa, Makoto Niijima, and Haru Okumura. They'll react to the battle whenever a fighter is KOed. At times, a platform will lower down onto stage as well, which has a cracked screen on it. This screen has a chance of showing either Morgana running or Teddie, referencing the loading screens of Persona 5 and Persona 4 respectively.
Yggdrasil's Altar
As the stage begins to rise from the ground to the skies, Cetacea can be seen flying with it shortly. Once airborne, the stage will occasionally feature Slimes or Tockles appearing to watch the battle for a while before exiting via leaping off or vanishing respectively. Very rarely, a Liquid Metal Slime will appear in the background of the stage for a very short amount of time, before quickly fleeing and jumping off similarly to Slimes.
Spiral Mountain
Randomly-selected flocks of 1-5 Jinjos fly around the mountain in circular patterns. Bottles pops out of various molehills around the mountain or on its summit, scratching himself often as he did in Banjo-Kazooie, as well as waving at the fighters. Mumbo Jumbo magically appears in various locations (including the mountain's summit, the entrance to Gruntilda's Lair, or the cliffs in the background), and juggles his eyeballs much like he did in Banjo-Kazooie: Nuts & Bolts. When the stage stops rotating and Gruntilda's Lair is visible, Gruntilda rides her broomstick around the mountain while cackling. Tooty constantly runs along the path going through the Mountain's various landmarks (occasionally stopping to wave at the fighters above). Numerous Buzzbombs fly around as well. Unlike other characters, Tooty and Buzzbombs can be seen even while the camera is rotating. With the exception of Mumbo Jumbo, all Spiral Mountain background characters received new original artwork for their Ultimate Spirits.

King of Fighters Stadium
A number of characters from various SNK franchises appear in the background watching the fight, akin to how selected fighters would "wait for their turn" in The King of Fighters '94-'98. It is random which characters will appear, but selecting specific music to play will sometimes guarantee the appearance of a character. For example, selecting the "Pasta - FATAL FURY 2" song will guarantee that Andy Bogard appears on the stage. A total of 20 different characters may appear in the stage, from several series such as Fatal Fury, The King of Fighters, Art of Fighting, Psycho Soldier and Ikari Warriors.
Garreg Mach Monastery
A number of characters from Fire Emblem: Three Houses appear in the background watching the fight. The house of affiliation of the characters in the background depends on the phase of the stage; characters from the Blue Lions will appear in the Marketplace, along with the Gatekeeper standing near the main gate, characters from the Black Eagles will appear in the Reception Hall, characters from the Golden Deer will appear on the Bridge, along with a Pegasus Knight flying in the background, and finally characters from the Church of Seiros will appear in the Cathedral.
Spring Stadium
Numerous 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.

Minecraft World
Two of a randomly selected farm animal will appear as soon as the stage starts. These include cows, sheep, and chickens. Some biomes may feature Villagers that perform farmwork during the day. They can be seen occasionally turning to fighters and watch the battle when close. At nighttime, Villagers retire to their homes and two different types of monsters will appear. These include a Zombie, an Enderman, a Skeleton, and a Spider; they do not affect gameplay. When morning starts, the monsters will either catch fire and burn up or simply retreat depending on the monster, repeating the cycle.
Cloud Sea of Alrest
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.
Mishima Dojo
Heihachi Mishima, in his older appearance, makes a cameo in the background of the Mishima Dojo. He initially sits down with his back turned to the fight, and will stand up once a fighter is KO'd, and later react to following KOs.
Trivia
- Northern Cave and Hollow Bastion are the only non-Smash original new stages in Super Smash Bros. Ultimate that do not feature at least one background character.
