Labyrinth is an edited character which is supposedly the result of Alice Margatroid interacting with, being hideously mutated and brainwashed and losing her mind to the Elder Gods, as is explained in several files included with it.
Labyrinth is a Cheap Character which utilizes "bugs" spawned during certain moves (and whenever it is hit in their default palette) to completely immobilize and cripple almost any opponent, if not kill them outright. Several of its attacks are projectiles such as fireballs, and others involve armored tentacles sprouting out of its body or the area around them. When controlled by the player, it is surprisingly clumsy to use, being laid out in a 5-button manner with one button having no neutral input.
It should be noted that it has a 12th palette mode and that its default palette is 12, and changing it to a lower number will set how strong it is. In its 12th palette, its Life cannot drop below 1 by normal means or by the use of debug keys. Even on palette 1, however, it is still extremely strong and is capable of taking out most characters with ease, but is defeatable.
