Weather Manipulation

Weather Manipulation is the Quirk used by Nine.

Description
Weather Manipulation allows its users to manipulate the weather in various ways. Nine has shown he is capable of creating large storm clouds that envelop entire islands, summon lightning bolts, and even create giant tornadoes. This Quirk also allows him to manipulate wind and grant him flight. The storms created from this Quirk are strong enough to severely damage an entire island.

Weaknesses
Weather Manipulation power puts an enormous strain on the user's body, causing cellular degeneration. For Nine, this effect was worsened after receiving All for One.

The lightning bolts generated from this Quirk can be absorbed by Denki's Electrification.

Usage
Nine is very proud of his Quirk's power and its capabilities. However, due to the severe cellular degeneration of this Quirk, he sought Cell Activation to negate its effects and allow him to use Weather Manipulation to its fullest extent.

Nine has used his Quirk for offensive purposes, summoning lightning bolts to incapacitate his opponents. When enraged, Nine unleashed Weather Manipulation's full power, forming a gigantic tornado and creating multiple more lightning bolts that heavily damaged the island he was fighting on.
