Twister (たつまき, Tatsumaki, or ツイスター, Tsuisutā?) is a subset of Command Materia in Crisis Core -Final Fantasy VII-. They involve Zack spinning around several times to attack, hitting all enemies in a wide area and possibly hitting the same enemy multiple times.
The basic Twister attack, Assault Twister, deals only half the damage of a regular attack. The upgraded form, Assault Twister+, attacks with the force of a regular attack and is capable of dealing double damage. Assault Twister costs 8 AP to use, and Assault Twister+ costs 16 AP.
There are three other Twister attacks: Poison Twister, Stop Twister, and Death Twister. Poison Twister and Stop Twister have a chance to inflict Poison and Stop respectively, while Death Twister has a chance to inflict Instant Death. Poison Twister and Stop Twister cost 16 AP, and Death Twister requires 20 AP. The different versions of Twister can be made through Materia Fusion, as none of them are available in the shop.
