Stage Description
This stage is played on an F-Zero track where players have to use Captain Falcon's ship, F-Zero racers, and hovering objects as platforms. If a player falls on the track beneath the racers, the player will start speeding to the left and be KO'd, unless the player quickly jumps back to safety. At other times, there is no track under the racers, and a fall at that time would result in death. The background scrolls incredibly fast and death upon hitting the track is nearly instantaneous. Items that float in mid-air (Flippers, for example) are also affected by the stage's movement, scrolling to the left.
Players can KO opponents at 0% damage easily by luring them to the car at the far left, grabbing them, and throwing them to the left. The foe will try to get up first, but while getting up, they will be KO'd. This works better if the foe is a heavy and slow character, such as Bowser.
 Tournament legality
Big Blue is banned in tournaments, in both Melee and Brawl. The primary reasons are that the track can easily cause SDs, the abundance of platforms causes the stage to favour good jumpers, and it allows excessive circle camping and stalling to be performed easily.
Big Blue is a race track that has first appeared in F-Zero and later appeared in F-Zero X. In the manual for F-Zero is a comic book of Captain Falcon's first bounty missions. Captain Falcon manages to shoot and kill a criminal for money, which makes rival bounty hunter Samurai Goroh angry. Captain Falcon escapes from Samurai Goroh with his Falcon Flyer and flies away. The Falcon Flyer never appeared in the game F-Zero itself or in F-Zero X. The Falcon Flyer seen in this stage looks very similar to the Falcon Flyer in the manual comic. The overall design of this stage resembles the Big Blue tracks in F-Zero X (such as the buildings in the far background and the design of the dolphin signs) with the overall straight design possibly coming from Big Blue Quick Turn (fifth track on the Queen Cup in the game), whose corkscrew layout gives the track the illusion of being a long stretch sometimes; however, F-Zero X's Big Blue does not feature jumps or a loop and the layout of the track in Melee and Brawl is randomly generated. The F-Zero machines are taken from the F-Zero machines featured in F-Zero X.  The race seen in the F-Zero Grand Prix stage of Adventure Mode also happens on Big Blue, but this one seems to be based instead on Big Blue Cylinder (fifth track of the Jack Cup in F-Zero X), given the tubular structure on the background on which the racers are seen before speeding through the stage.
There are two music tracks that play on this stage. The primary track comes from F-Zero's track Big Blue. While the track first appeared in F-Zero, it sounds more similar to "Decide in the Eyes", the song's hard rock version that plays on F-Zero X. The alternate track comes from Mach Rider. The track is a mix between the title screen theme and the piece that can be heard when playing on the courses.
