Bravely Default (ブレイブリーデフォルト, Bravely Default) is a series of role-playing games developed by Silicon Studio and published by Square Enix in Japan, with Nintendo publishing in all other regions. Originally conceived as a sequel to Final Fantasy: The 4 Heroes of Light, the connections to the Final Fantasy franchise were eventually dropped in favor of original characters and settings. Battles are turn based, with the unique twist of being able to brave or default every turn. Brave Points (BP) must be spent to attack, or "Brave" enemies, and more available BP means more chances to attack. The player can even go into negative BP, but are then unable to perform any action until the BP balance reaches 0 again. BP will restore naturally, or the player can choose to "Default," which reduces damage taken and replenishes BP quicker. The game also utilizes a job system to give characters special abilities in battle

On February 23, 2021, it was announced that spirits from Bravely Default II, the third game in the series, would be added to the Spirit Board in a Spirit Board event simply titled BRAVELY DEFAULT II on February 26 as a tie-in to the game's release. All four protagonists are available in pairs: Seth & Gloria and Elvis & Adelle.

Dependent universes

Dependent universes are universes that are technically represented in some form in the Super Smash Bros. franchise, but are not considered their own series.

• Anarchy Reigns is an open world beat 'em up game developed by PlatinumGames and published by Sega. The fighter spirit artwork of Bayonetta from the first Bayonetta game, as well as some of her alternate costumes, come from this game.
• Dance Dance Revolution is a series of dance rhythm games by Konami and one of many franchises developed by Bemani. A sticker of Bowser uses artwork from Dance Dance Revolution: Mario Mix. Mario's down smash in Ultimate also resembles his breakdancing on that game's cover art, as opposed to just his leg sweep from Super Mario 64 as it was prior.
• DreamMix TV World Fighters is a crossover fighting video game published by Hudson and developed by Bitstep. Simon Belmont received his Japanese voice actor in Hideo Ishikawa through this game.
• Eggerland is a series of puzzle games developed by HAL Laboratory. The games' main protagonists Lolo and Lala served as direct inspiration for the Lololo and Lalala characters from the Kirby series, who appear on their door on the Mt. Dedede Boss Rush Lobby phase in Dream Land GB.
• Final Fight is a series of beat-em-up games made by Capcom. The series is a spinoff of Street Fighter, hence why Cody, one of the series' protagonists, appears as a playable character in several Street Fighter games and receives a spirit in Ultimate, referencing his appearance in Street Fighter Alpha 3.
• Flicky is an arcade platformer made by Sega. Flicky, the game's eponymous character, is the basis of the Flicky animal friends from Sonic the Hedgehog, which appear on Windy Hill Zone and as part of a trophy in SSB4.
• The Halloween Hack is an unofficial ROM hack of EarthBound created by Toby Fox, who would later go on to create Undertale. The music track MEGALOVANIA made its debut in this ROM hack.
• Killer Instinct is a fighting game franchise created by Rare. The music track Funky's Fugue was originally written for an internal update video for the first game in the series. It was later repurposed for Donkey Kong Country.
• Kingdom Hearts is an action-RPG series primarily developed and published by Square Enix, with the brand owned by The Walt Disney Company. The series is a crossover between properties from both companies as well as original assets owned by Disney. The first Kingdom Hearts game marked the debut of Takahiro Sakurai as the consistent voice of Cloud Strife. Some of Sephiroth's moves (like Shadow Flare) were adopted from this series by Dissidia Final Fantasy, which then became the basis for their Smash appearance. Aerith's name was retranslated to better match her Japanese name. Additionally, Sephiroth's one wing debuted in the original game; it was derived from the title of his battle theme in Final Fantasy VII, "One-Winged Angel", which reappears throughout the series and in other Compilation of Final Fantasy VII installments as Sephiroth's general theme.
• Legend of the Chambered is an action RPG developed by Notch, the creator of Minecraft. Many of the sprites used for the weapons and armor in Minecraft originated in this game, and were later reused.
• Lode Runner is a 2D puzzle-platform game, published by Broderbund and developed by Hudson Soft. Bomberman's current design is based on the enemies from the NES version of this game.
• Marvel vs. Capcom is a fighting game series featuring characters owned by Capcom and Marvel Comics. Mega Man's up tilt is based on the Mega Upper from this series, and Ken's Shinryuken is based on its incarnation from this series, although neither originate from the series. The series is also indirectly referenced by Palutena's Guidance in the conversation about Ryu.
• Meteos is a series of puzzle games developed by Masahiro Sakurai and originally released for the Nintendo DS. The X Bomb's behavior in the Super Smash Bros. series is similar to that of the item of the same name in Meteos, in which it explodes in a cross shape rather than exhibit its behavior from Kid Icarus: Uprising.
• Mystery Dungeon is a series of roguelike and role-playing games developed primarily by Spike Chunsoft. While the Chocobo's cartoonish design is unique to Final Fantasy's Chocobo subseries, its design for the Mii Costume is based on the latest title of the Chocobo's Mystery Dungeon trilogy, being Final Fantasy Fables: Chocobo's Dungeon in Smash 4 and Chocobo's Mystery Dungeon: Every Buddy! in Ultimate.
• Policenauts is a sci-fi adventure game made by Hideo Kojima for Konami. One character, Meryl Silverburgh, would serve as the basis of a character by the same name in the Metal Gear series, who appears as a sticker in Brawl and a spirit in Ultimate.
• Pulseman is a platformer game made by Game Freak and published by Sega. Pikachu's Volt Tackle is inspired by the Volteccer, Pulseman's signature attack, and even has the same name in Japanese.
• Rad Mobile is an arcade racing game made by Sega. The game is mentioned on Sonic's fighter Tips in for Wii U and Ultimate as Sonic's first appearance in a video game.
• Shin Megami Tensei is a post-apocalyptic RPG series made by Atlus. Persona is a sub-series of Shin Megami Tensei. The Tsubasa Oribe and Tsubasa Oribe (Carnage Form) spirits in Ultimate originate from Tokyo Mirage Sessions ♯FE, a pop idol-themed crossover between Shin Megami Tensei and Fire Emblem. Joker's down special moves, Tetrakarn and Makarakarn, first appeared in 1992's Shin Megami Tensei for the Super Famicom.
• Table Tennis is one of the games included with the Magnavox Odyssey, the first home video game console. After distributing the Odyssey in Japan, Nintendo acquired a license from Magnavox to produce their own dedicated game consoles. The Color TV-Game 15's version of Table Tennis appears as an Assist Trophy in Smash 4 and Ultimate.
• Warriors is a hack-and-slash series by Omega Force (stylized as ω-Force) and Koei Tecmo (previously Koei prior to their merger with Tecmo). Originally a spin-off to Koei's Romance of the Three Kingdoms series titled Dynasty Warriors, the game would spawn an entire sub-series of games under the Warriors title or otherwise have the same type of gameplay, including having crossovers with Dragon Quest, The Legend of Zelda, Fire Emblem, and Persona series. Spirits from Hyrule Warriors: Age of Calamity appeared in Ultimate via a Spirit Board event. Additionally, Sophia from Persona 5 Strikers, a Persona 5 spin-off, is available as a spirit for those who have save data from the game in the system. She will be available to purchase from the Shop at a later date.
• Yume Kōjō '87 (lit. "Dream Factory '87") was a promotional event held by Fuji TV in 1987 in Japan. Yume Kōjō: Doki Doki Panic is a game featuring the mascots of this event, which was localised as Super Mario Bros. 2 and eventually re-localised back to Japanese as Super Mario USA. Mushroom Kingdom II is based on the Super Mario All-Stars version of the game, and characters from the game such as Birdo, Pidgit and Shy Guy have appeared in various forms as parts of the Mario and, in some cases for Shy Guy, Yoshi universes, In fact, Birdo and Shy Guy's Trophies in Smash 4 mention the game sans Yume Kōjō '87. Additionally, Lina's floating jump, a special ability which was then inherited for Peach in Super Mario Bros. 2, appears as a mechanic for Peach since her debut in Melee, also being inherited for Daisy in Ultimate.
