|Appearance||Super Smash Flash 2|
Rainbow Route, formerly titled Mirror Chamber, is a starter stage in Super Smash Flash 2 based on the primary location from the game, Kirby & the Amazing Mirror. It is very similar is terms of appearances to Super Smash Flash's Kirby Hub Room.
Rainbow Route once again appears in Super Smash Flash 2, but this time as a full-fledged stage. The main focus on this stage appears to be the blue platform in the middle below the golden mirror that served as the entrance to the Mirror World in Kirby & the Amazing Mirror. It regularly opens and closes.
It should be noted that for its appearance in Super Smash Flash 2, Rainbow Route once again uses its original tiles, albeit revamped this time.
- The main track is titled Rainbow Route, a remix of Nature Area from Kirby and the Amazing Mirror.
- The alternate music track is titled Speed Eaters, a remix of the mini-game from the same game.
Rainbow Route is located at the heart of the Mirror World. It connects to each of the levels that Kirby must enter to find the Mirror Shards. It begins as a simple grassland, but the scenery changes depending on where it's located, such as having a mountainous terrain when approaching Mustard Mountain, and pine forests surrounding Carrot Castle. Being the first level, the earlier parts of Rainbow Route do not have many challenges and is overall easy to venture through. As Kirby's quest progresses further, he moves to harder and more diverse parts of Rainbow Route, which have more complex puzzles and a wider array of enemies and impediments. The only place Rainbow Route does not come in direct contact with is the final level, Candy Constellation. SSF and SSF2 appearance is directly taken or based on the starter chamber where the Mirror Shards are placed and Kirby can access to other locations via special mirror doors.
This stage is a counterpick in competitive play. Rainbow Route was originally seen as a decent stage when hazards were turned off. However, as more characters with long or disjointed range rose to prominence, players realized that the stage was more favored towards these types of characters. The floating platform in the center gives anyone who is underneath it complete control over the stage. The stage itself is also rather large with small blast zones, giving a further advantage to characters with strong onstage presence, bad recovery, and high knockback. Though the stage was banned for over a year, it has recently been restored due to further developments in the metagame that have diminished the impact of the stage's flaws.
