Intamin built several "Impulse Shuttle" coasters, such as Vertical Velocity and Superman: Ultimate Escape, in 2000 and 2001. However, Wicked Twister has several changes from these previous coasters. Both vertical spikes have twists, whereas the previous rides had one straight and one twisted spike. Also, the train on this coaster seats more people than the trains on earlier Intamin Shuttles.
