The X-Tornado is a transforming jet/walker machine that appears in the anime series Sonic X. It was built by Miles "Tails" Prower and Chuck Thorndyke.
The X-Tornado was created when Tails' Tornado-2 plane proved to be no match for Dr. Eggman's E-90 Super Sweeper. It was designed with two engines in order to to accommodate the continual gain of energy from the Chaos Emeralds. It also has a hidden afterburner in the plane that can dramatically increase the speed of the X Tornado. It was later equipped with a variety of transformations like the X-Cyclone and a Battle Armor mode. The X Tornado is equipped with a ring launcher to power-up Sonic when a time came for him to destroy one of Eggman's robots. If a ring was also connected to a yellow conduit under Tails' chair, Sonic can be powered by the energy given off from the ring with the X Tornado.
