Cyber, also referred to as cyber culture or cyberculture, is the name given to a subculture that has roots in multiple youth scenes including the goth and rave/clubbing scenes. Someone who identifies with the Cyber subculture can be referred to as a "cyber", although the term "cybergoth" is used to refer to the goth-influenced end of the movement, i.e., those who would attend clubs such as Slimelight or The Wendy House, and "cyberkid" to refer to those who attend trance/hard dance clubs such as Gatecrasher. While fashion and an interest in electronic dance music are two areas that define the cyber subculture, cybers also tend to have a general interest in new and future technology, its influence on society, and other such cyberculture topics. The subculture enjoys niche status and a relatively small following.

Fashion

Cyber fashion resembles a combination of rave and goth fashion. Some common themes include the use of starkly contrasting colours such as black, white, luminous neon and/or UV-reactive colours and materials, brightly coloured and often stylised hair (e.g., with hair extensions or braids using artificial materials, often with an undercut shave), large shoes or boots (typical brands include Swear and Transmuter), various forms of body modification, the presence of superfluous goggles (especially aviator-style), androgyny and the influence of cyberpunk or anime themes.

Music

Associated music is heavily electronic in nature, covering both alternative electronic genres such as electronic body music, futurepop, club oriented dance music styles such as trance and hard dance, and other electronic genres including drum and bass, synthpop, gabber and intelligent dance music.
