Miiverse is a stage in Super Smash Bros. for Wii U. It was revealed during the Super Smash Bros. for Wii U: 50-Fact Extravaganza on October 23rd, 2014, and added to the game in version 1.0.8 on June 14th, 2015. It featured a unique stage element: user-created Miiverse posts drawn in support of a particular fighter would appear in the background. Due to the discontinuation of the Miiverse service, these posts no longer appear as of November 8th, 2017.
Its layout is similar to Battlefield, though it is slightly wider, the platforms are longer, and the ceiling is slightly higher, giving it the highest ceiling among SSB4's legal stage list.
Selected messages created by users appeared in the background, intended to cheer the fighters on. Users were able to post drawings for each character in dedicated Miiverse communities, which would then appear when that character participated in a match. The post's border color corresponded to the slot of the character the post was cheering for. During the results screen, players had the option to send a post directly to Miiverse community to the character who won the match. This prompt occurred even if Miiverse was disabled on the system, but would not appear if playing with amiibo, seemingly due to the inability to suspend the game while amiibo are in use.
This stage is not available when playing against others online, making it the only stage with that restriction. When playing locally, this stage can be played even with the Wii U not connected to the Internet. Doing so will cause no messages to appear; this was the case even when the service was active.
Certain events caused additional Miiverse posts to appear:
The Miiverse social network was discontinued as of November 8, 2017; after that date, this stage no longer has posts displayed in the background, and users are not able to post new drawings to its communities.
The Ω form removes the thin platforms and resembles a smaller version of the Online Practice Stage. In addition, the length of the stage increases slightly to match that of Final Destination. While the service was active, Miiverse posts would still appear in the background as long as players were connected to Nintendo Network.
Miiverse's appearance is based on its namesake's interface: they both feature a white and green color scheme, as well as a gray checkered background.
Miiverse is either considered legal as a purely cosmetic Battlefield alternative or banned due to its redundancy as a semi-clone of said stage. When the service was active and the Wii U was connected to the internet, the posts in the background could be distracting for players and may contain inappropriate material. However, with Miiverse now closed, no posts will appear in the background, helping the stage's case for legality.
