Sumabura Ken!! (スマブラ拳!!) is the name given to the Japanese Super Smash Bros. development information websites; the Melee edition is named Sokuhou Sumabura Ken!! (速報スマブラ拳!!), while the Brawl edition came to be known as Smash Bros. DOJO!! in other countries. The term "Sumabura Ken!!" (or "Smabura-Ken", from a mention on the English Brawl DOJO!!) is commonly used to refer to the Melee's Sokuhou.
The pages are written by Masahiro Sakurai and other developers during the creation of each game. The websites give information about characters and modes as they were in development. Melee's Sokuhou Sumabura Ken!! was updated between May 2001 and February 2002.

The Super Smash Bros. Melee Smabura-Ken contains interesting tidbits about it's development, including details about how Marth and Roy were intended to be removed from the game in international release.
Even more interestingly, it details about how James Bond was briefly considered for the game, and that Sakurai had dropped him quickly, stating that "he couldn't use the actor's likeness", and that guns weren't appropriate for a child's game. This was a turning point for the game and technically wrote the Smash Bros. Fighter Ballot's 'No Non-Video Game Character' rule.
