Twister resembles a small, orange top with yellow floating 'arms'. From game to game, Twister's appearance remains much the same, differing slightly in the shape of its bottom and top.
Twister makes its debut in Kirby's Adventure. When idle, it spins slowly in place. When Kirby approaches this enemy, it takes to the air and spins faster, chasing him. This attack is similar to the form of attack of the Tornado Copy Ability, which Twister grants when inhaled. While spinning, Twister is invincible to most attacks.
Twister's form of attack does not change very much from game to game. However, in some games, Twister is able to pass through walls and sometimes travel off of the screen in some games.
In Kirby's Pinball Land, two Twisters are located at the top level of Whispy Woods Land. When Kirby hits one, he rolls right through it without harming it in any way. Doing this will earn the player 100 points.
