Downloadable content, usually abbreviated as DLC, is additional content available to download after the initial release a game. DLC was first confirmed for Super Smash Bros. 4 in the "Super Smash Bros. for Wii U: 50-Fact Extravaganza" video presentation on October 23rd, 2014. Downloadable content for the game includes playable characters, stages, and even additional features. Paid content in Super Smash Bros. for Wii U is found for purchase in the Nintendo eShop, and in Super Smash Bros. for Nintendo 3DS is found within a game-based DLC shop.

Updates to the game are downloadable at no extra cost. The game must be updated to the latest version to purchase DLC, which is done automatically after starting the game from the console's main menu. Most updates also adjust game balance and mechanics, while fixing glitches and other errors as well. Change-logs for all updates is available at the links above. Nintendo has not released any detailed information as official announcements.
As with any other game, DLC data gets 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 DLC paid for. ("With Anyone," "With Friends," and local Nintendo 3DS Versus). Using amiibo as Figure Players (FPs), saving uploaded or shared replays, and even illegal hacking are some alternative methods without the need of people with DLC.
Similar to clone characters, DLC characters are recognized by being placed in a particular area on the character selection screen, regardless of which franchise from which they hail. When more than four DLC characters are on the 3DS version, and all other characters are unlocked, the DLC characters are labeled "Extra Fighters" on a separate page.
DLC characters also lack custom moves, and all have a generic, previously unused Palutena's Guidance scene. While there are no official reasons for this, the former is presumably due to time and budget constraints, and the latter is presumably due to repeatedly bringing back voice actors each time a character is released.
Mii Fighter costumes
Additional costumes for the Mii Fighters are available as paid DLC.
Trophies of fighters for All-Star Mode and Classic Mode are included upon purchasing the fighter, as well as additional trophies:
