Lunar Core

Lunar Core is a stage in Super Smash Flash 2.

Layout
The stage consists of three large platforms that are connected by staircases and two platforms that are situated on the upper right and upper left portion of the stage that is not connected to the rest and therefore must be jumped to. At certain times, multiple red beams will streak across the stage, harming any player in its path.

Music
The BGM of Lunar Core is a remix of the Final Battle when you're fighting Zeromus in Final Fantasy IV.

Origin
Lunar Subterrane, also known as Lunar Core in the advanced version of Final Fantasy IV is the final dungeon in the mentioned game and can only be accessed from Crystal Palace after the Giant of Babil is destroyed.

Tournament Legality
Originally, Lunar Core was seen as a tournament legal counter-pick stage when hazards were off. However, as the metagame progressed, people started realizing that the stage was to big and promoted camping to much. This along with certain characters being able to run out the clock during matches resulted in the stage becoming banned.
