In the Super Smash Bros. Ultimate Nintendo Direct on November 1st, 2018, Masahiro Sakurai confirmed that paid DLC would be available for Ultimate. The initial wave of content comes in the form of five Challenger Pack bundles, each containing one entirely unique fighter, one stage, and several music tracks. These bundles, which are also available through a complete pack known as the Fighters Pass, had the release deadline of February 29, 2020. Additionally, was available for free as a limited time early purchase bonus, and is currently available for purchase separate from the Fighters Pass. On November 6th, 2018, Sakurai announced on his Twitter account that the initial DLC line-up was finalized, and that potential fighters were proposed by Nintendo, with Sakurai passing final approval on them.

During the Nintendo Direct on September 4th, 2019, Nintendo revealed that more DLC fighters were set to be in production after the first Fighters Pass, due to Ultimate's strong sales. As with before, Nintendo proposed the potential fighters and Sakurai passed final approval. On January 16th, 2020, Fighters Pass Vol. 2 was announced alongside, with the previous Fighters Pass retroactively being dubbed Vol. 1. The Pass includes six Challenger Packs; just like in Vol. 1, each pack contains one fighter, one stage, and several music tracks. Both Byleth and Vol. 2 were made available for purchase on January 28th, 2020. These six packs had the release deadline of December 31st, 2021. According to Sakurai, this is planned to be the last DLC released for Ultimate. He also expressed caution that the DLC characters for the Fighters Pass Vol. 2 could face delay or that development could be stopped indefinitely due to the ; although development continued through remote working and ultimately went smoothly, without problems and concluded on October 18th, 2021. Fighters Pass Vol. 2 was originally planned to have five fighters, like the first pass, but was increased to six when 's inclusion was successfully negotiated for.

Updates
Updates to the game are downloadable at no extra cost. In order to use DLC and access online modes, the game must be updated to the latest version, which can be done automatically by starting the game from the system's Home Menu, or manually triggered from the Switch's Home Menu. Most updates also adjust game balance and mechanics, while fixing glitches and other errors as well. Changelogs for all updates are available at the links above.

As with any other game, DLC data is added via free updates. Completing a transaction to receive DLC is merely a "ticket" to grant access to said content. What this means is that DLC not purchased in an updated version is still technically installed but locked, and thus is accessible indirectly. Content that is locked can be seen and played against with opponents connecting via a system that has paid for the DLC (within Wireless and Online modes). Aside from this, locked content can also be seen using amiibo as Figure Players, and saving uploaded or shared replays.

Fighters
As every veteran is in the base game and none were cut, all DLC characters are newcomers.

After awakening 10 fighters in Adventure Mode: World of Light, all downloaded DLC fighters are unlocked for use as well.

Trivia

 * is the only DLC character with a unique Palutena's Guidance conversation.
 * With the sole exception of Piranha Plant (referred to by its Japanese name "packun"), every downloadable fighter’s name in the code differs from that of their actual names. 's code name is "jack" (Arsène's code name is "doyle"), 's is "brave," 's is "buddy" (with Kazooie specifically sometimes referred to as "partner"), 's is "dolly," 's is "master," 's is "tantan," Steve's is "pickel" (Creeper’s codename is "scarier"), Sephiroth's is "edge," 's is "eflame," 's is "elight," as a pair Pyra & Mythra's is "element" (Rex's codename is "diver"), 's is "demon" and 's is "trail."
 * According to Masahiro Sakurai, Fighters Pass Vol. 2 was originally going to have five Challenger Packs as with the first Pass, but Sora's inclusion was secured after the other five fighters were already determined, resulting in an "extra" Challenger Pack.
 * Following most DLC fighter reveals, the Super Smash Bros. Ultimate Official Site was mistakenly updated to add fighter slots for recently revealed fighters without removing corresponding "mystery fighter" slots, resulting in extra empty slots that never corresponded to actual unrevealed fighters.
 * Banjo, Kazooie, Min Min, and Sora are the only DLC characters whose voice clips are recycled from their own games rather than recorded specifically for Smash, while Piranha Plant and Steve are the only DLC fighters to not have any voice clips.
 * In North America, when trailers for new Mii Fighter costumes are shown off, costumes of characters that are from a franchise that typically have M-rated installments from the ESRB only show the name of the character alongside the Super Smash Bros. Ultimate logo, rather than the logo of the franchise the character is from. This has occurred with Altaïr (Assassin's Creed), Vault Boy (Fallout), Travis Touchdown (No More Heroes), Dragonborn (The Elder Scrolls V: Skyrim), Dante (Devil May Cry), and Doom Slayer (Doom).
 * Four of the Mii Fighter costume reveals would additionally gain a "rated TEEN by the ESRB" notice when the character's respective logo for a series that typically has T-rated installments from the ESRB appeared, those being the Hunter's Mail and Rathalos Mail (both from Monster Hunter), Lloyd (Tales of Symphonia), and Shantae (the series of the same name, possibly referring to the games Shantae and the Pirate's Curse, Shantae: Half-Genie Hero and Shantae and the Seven Sirens, as the first two installments are not T-rated).
 * Oddly, even though Altair, Vault Boy, and Travis' game logos were shown in the European versions of their trailers, this did not happen with Dragonborn, Dante or Doom Slayer, as their game logos are only shown in the Japanese versions of their trailers.
 * Persona, another series that typically has M-rated installments, did not originally follow this pattern. However, starting with Byleth's presentation, the North American versions of the Mr. Sakurai Presents presentations removed the logos of the games each of the DLC fighters hail from when showing an overview of the Fighters Passes, possibly due to Persona 5's rating.
 * Later in 2022, an article on Nintendo's website detailing Ultimate's reveal trailers refers to Persona 5 as "Joker's original game".
 * In a similar vein, the UK version of the Super Smash Bros. Ultimate website shows Kazuya's series as Super Smash Bros. Ultimate × Kazuya rather than Super Smash Bros. Ultimate × Tekken like in other regions. The logos for other franchises in the "Display by Series" option of the Fighters page would later be removed from the European websites due to this.
 * Oddly, when the Mii Fighter costumes for Barret and Tifa were shown, the trailer in Sephiroth's Mr. Sakurai Presents video as well as the separately-uploaded trailer with the Wave 8 Mii costumes uploaded the same day shows the logo of Final Fantasy VII next to the Super Smash Bros. Ultimate logo. However, the separate video was taken down and reuploaded on January 11, 2021, and the Final Fantasy VII logo was changed to just Final Fantasy.
 * This may be due to rating issues, which can be evidenced by how Sephiroth's page on the North American website includes a "FINAL FANTASY VII RATED TEEN BY THE ESRB" message, which also applies to Pyra/Mythra and Kazuya's pages with their respective games.
 * Despite that, the Super Smash Bros. Ultimate × Final Fantasy screen still appears during the Chocobo reveal, though this is likely due to the fact that the character is not tied to any specific installment.
 * At the end of October 2019, on the North American English-language official site only, Piranha Plant's purchase cost was incorrectly changed from US$4.99/CA$6.29 to US$5.99/CA$7.55 to match all of the other fighters. This error remains as of October, 2023. The actual eShop price charged remains the correct (lower) price. This error does not appear to be present in any other languages or regions.
 * Masahiro Sakurai revealed in a YouTube video that he considered releasing all music tracks in the base game as free downloadable content. This is due to the combined ROM data having been larger than the allotted 16 gigabytes of space a Nintendo Switch cartridge could hold at the time. This was prevented when a new way to compress audio files was invented so music tracks now take up a quarter of the space they used to without any loss in audio quality.
