King of Fighters Stadium
King of Fighters Stadium (KOFスタジアム, KOF Stadium) is a downloadable stage for Super Smash Bros. Ultimate. It was released on November 6th, 2019 as part of Challenger Pack 4, being the home stage of Terry. The stage is a large arena themed around the King of Fighters tournament, which was featured in the Fatal Fury series before branching out into its own series with the same name.
The stage's layout is a simple flat ring, similar to most stages in the Fatal Fury and The King of Fighters series, which is slightly elevated above ground level. It takes place in a large, arena-like stadium close to the center of a gridiron football field. Similar to both Pokémon Stadium and Boxing Ring, a large jumbotron that records the on-screen action can be seen in the background. Invisible walls are on both sides of the stage, blocking the respective blast lines; these walls can be broken by dealing enough knockback to a fighter, akin to the shields in Home-Run Contest from Brawl onwards. However, fighters can still be knocked into the vertical blast zones with enough knockback.
In addition to the invisible walls of the side, there is also an invisible ceiling above the upper blast zone, which prevents players from getting over the walls, as technical limitations prevent them from having an infinite height.
Background characters from Fatal Fury and The King of Fighters make cameos just outside of the ring, similarly to how they do while watching the fight in the early The King of Fighters games. There are 20 in total, but only three or four will appear in a single match. While they are normally random, the choice of music will guarantee specific characters to appear. If there are more than four players in a match, no characters will appear.
Several additional effects occur whenever a player scores a KO: the crowd cheers, background characters react, smoke machines on the football field deploy multicolored smoke trails, sparklers on the arena activate, and the "King of Fighters" logo above the jumbotron lights up in multiple colors.
No changes are made when hazards are turned off.
Ω form and Battlefield form
The Ω form and Battlefield form are set far above the ground overlooking the field. The main platform resembles the ring of the normal form, but resized and reshaped to match Final Destination and Battlefield, respectively. The three soft platforms of the Battlefield form are metallic and are unique to this form. The invisible walls of the normal form are removed in keeping with the stages of their respective forms. The character cameos remain present in both forms, appearing in the background of the main platform. The additional effects that occur after a KO remain in both forms.
The following characters cameo in the background of the stage.

Cameos for specific music
During the "Mr. Sakurai Presents Terry Bogard" video, Masahiro Sakurai notes that some character cameos will always appear depending on the music track that is playing. The following is a list of confirmed cameos with accompanying music.
Rather than being a stage based on Terry, such as his iconic Transcontinental Railroad stage, King of Fighters Stadium is an original design based on the various arenas from The King of Fighters series. Its overall open-field design, muted metallic tone, and design of the stands along with the jumbotron bearing the King of Fighters logo, most prominently resembles a mixture of the Stadium stage from XII and the Antonov Super Arena from XIV. However, the bold green design of this logo is completely original to Smash, and the circular design of the main platform appears closest to Kagura Stadium from '96, including the "KOF" logo in the center, which has a Smash logo in place of the "O". While these stadium stages in The King of Fighters series all appear to be dedicated venues for fighting tournaments, the one seen in Smash is an adapted American football stadium.
The layout of the stage is designed after a traditional fighting game like the Fatal Fury series, where the layout is flat and even, and ringouts are uncommon. The breakable walls are inspired by Real Bout Fatal Fury, which features a similar mechanic; in that game, however, the walls permanently break after enough damage, and they are usually not invisible. The stage's day/night cycle is a reference to a similar effect many stages in the Fatal Fury and The King of Fighters series go through, namely shifting from day to dawn to night (not always in this order) as rounds begin and end.
"King of Fighters" is a recurring tournament in SNK's gaming universe. The concept was first introduced in Fatal Fury: King of Fighters, although canonically, the first time a King of Fighters tournament was ever held was in Art of Fighting 2. Recently, the tournament's most prominent appearances are in The King of Fighters series, which was based on the idea developed in both series, as well as Ryo Sakazaki's appearance as a secret extra opponent in Fatal Fury Special.
