LEGO Xalax, also know as Crash 'em Racers was a Racers subtheme which was introduced in 2001 and discontinued the same year. These sets used special Xalax Figures which were not minifigure scale. The Xalax Figures were customized figures that were slightly taller then an average LEGO bricks, but still shorter than 4 plates high. Most Xalax sets included eight pieces since they were just different modifications of the same car.
