A stage is a location in which characters fight. There are currently twelve playable stages, each with their own unique Aether variant, featuring aspects such as the Sylvian Beast on the Aether variant of Treetop Lodge and the pillars of Rock Wall eventually breaking away after being damaged enough. As such, the Aether variants are meant for friendly matches, and are completely banned from competitive and online play.
Before each game, both players must decide which Stage is to be chosen through the banning system or alternatively by selecting the random option.
Currently, there are only three stages to have a unique skin (making 3 different unique variants of the one stage) is Rock Wall, with the promotional CEO skin able to be purchased and played on, Fire Capitol, which turns it into Neo Fire Capitol, and Merchant Port, which turns it into The Swampy Estuary.
