List of leaks
A leak is a revelation of information about a game that has been released prematurely, especially without prior permission to release such information.
Smash 64 and Melee leaks
Due to the lack of a developed infrastructure in the Internet prior to their releases, neither Super Smash Bros. nor Super Smash Bros. Melee had leaks of notable proportions prior to their release.
Brawl leaks
The significantly more developed Internet of 2007, however, made supposed leaks for Super Smash Bros. Brawl more common, particularly in the pre-release hype. The reliability of leaks, however, were invariably sketchy, with supposed contents of leaks sometimes being radically different than what the game actually contained. Upon Brawl's release in Japan in late January 2008, leaks could then cross-checked with the actual game; in addition, actual screenshots and videos of the game provided considerable information to players outside of Japan, most of which had not yet been revealed by the DOJO!!.
Smash 4 leaks
Leaks were particularly common in the pre-release of Smash 4, with fake leaks being extremely common. The arguably most popular leak was the Gematsu leak, which thousands of followers believed in its entirety before it was proven inaccurate by the inclusion of Robin and Lucina, and disconfirmation of Chrom, as playable characters. Other 'leaks' proved popular, such as a supposed leak showing Palutena as a playable character, the veracity of which is unclear.
In July 2014, a supposed email from Australian classification boards, OFLC, have supposedly indirectly leaked Wario as a playable character due to his use of flatulence contributing towards the game's rating.
