Tornado Kirby is one of Kirby's copy abilities, introduced in Kirby's Adventure. It allows Kirby to turn into a spinning tornado. It is commonly obtained from wind-based enemies, such as Twister.
The main ability of Tornado is to turn Kirby into a cyclone. In this cyclone form, Kirby is impervious to damage and damages enemies on contact. The transformation ends after a few seconds. Until Squeak Squad, it could not break star blocks. Return to Dream Land added a few more attacks, including a projectile minicyclone and a bigger Hyper Tornado.
