Disassembly Magic(分開 Punkai lit. Separation) is a Caster Type Magic utilized by several powerful mages.
The caster makes a net-like pattern which runs straight through whatever it touches, tangible or intangible. However, instead of being destroyed, the objects that are touched split apart and form numerous, smaller versions of the original. When used on a living organism, the recipient gets reduced into small, doll-like versions of themselves, complete with deadpan expressions. According to Gildarts, Natsu Dragneel was the first person to try to keep fighting after falling victim to this spell. This spell doesn't cause permanent damage since the object will return back to normal after a little while. Gildarts has also shown the ability to reconstruct the victim by motioning at the disassembled object. However, it is implied that Gildarts has trouble controlling this ability, as shown in his battle with Natsu.
