Super Smash Bros. 4 Official Site
The official website for Super Smash Bros. 4 launched on June 11, 2013, shortly after the two games' E3 2013 trailer. Like its predecessors, Smabura-Ken and the Smash Bros. DOJO!!, it was periodically updated with information on the games, but unlike its predecessors, the information was shown mostly through pictures instead of text. For a short time after a character was revealed, their image links would have an "UPDATE" banner affixed.
The website gives information about all of the characters and shows videos and images in both Wii U and Nintendo 3DS versions. On the main page, there is a picture that was changed every weekday. This picture was the most recent "pic of the day", which was also posted by Masahiro Sakurai in the Miiverse community called the Director's Room, where he started providing captions and sometimes additional pictures starting July 2013.
The language selection offered by the site includes English, Japanese, German, French, Italian and Spanish, like its predecessor Smash Bros. DOJO!!, in addition to the newly-added Portuguese, Dutch and Russian. For some languages, regional variations are available.
When a character was revealed, a banner under the daily photo that said "Warning! Challenger Approaching!" (a reference to the message that typically appears whenever unlockable characters are first encountered within a Super Smash Bros. game) was added. It remained there for a couple of days. The amount of time the banner stays up seemed to be dependent on how soon the next character would be revealed, though there was an approximate maximum and minimum timeframe.
Over time, the website was gradually fleshed out, later including Nintendo 3DS informational manuals about character movesets (Japanese version), as well as additional information regarding Pokémon, Assist Trophies, and music previews.
Each character confirmed for Super Smash Bros. 4 has their own character page. These pages can be accessed by clicking on the picture displaying the fighter on the website's front page. Each character page contains the characters' official render within a frame displaying their name, and ten additional photos. These pictures will be a mixture of Wii U and 3DS screenshots—there are typically more from the Wii U—and the Wii U pictures always precede the 3DS pictures. The background color of the page changes according to character. When applicable, these character pages will sometimes link to a recent or then-upcoming Nintendo game featuring the character. On special characters, such as newcomers and third-party fighters, there would often be a bonus video or piece of artwork alongside the main character render.
Unlike the website's predecessors, the Smash Bros. DOJO!! and Smabura-Ken, there is no additional text on the page regarding the character, except for Ryu, whose page explains the system for his Street Fighter-style inputs.
