The jetwall was a barricade created by a light cycle in the TRON era. The light cycle riders were in constant motion on the Game Grid, creating jetwalls behind them as they moved. Each jetwall matched the color of its light cycle. If a driver hit a wall either by accident or by having no more room to move, they were derezzed, their jetwall disappeared and the last rider standing won.Due to system constraints of the time, the light cycles, and by extension their jetwalls, traveled only in straight lines and made only 90°-angle turns during light cycle battles, though the vehicles themselves could move more freely off the Game Grid. In the TRON: Legacy era however, the jetwall was superseded by the Light Ribbon, a barricade rendered in the more fluid motion of the vehicles in the Tron system.
