The user can summon all types of natural disasters, such as tornados, acid rain, earthquakes etc. Whichever they create is purely based off of the current situation the user finds themselves in, and while they can control the movements and intensity of these disasters to a degree, they're mostly uncontrollable. For example, if it were raining then they could create acid rain, if they were touching water somehow, it would be a tsunami and if the user was within a windy area, it would be a tornado (you understand.)

Quirk Type - Emitter (Or if you wanted to take an extra mile, you could say the user can morph into the more solid forms of disaster (tornados and tsunamis) then it could be a Transformation quirk)

Best suited for - Offence (I genuinely can't think of many situations where others would be applicable, maaayyybe rescue if they learned to control it well and used like a flood or something to push people out of danger's way?? I don't really know)

Drawbacks - The user is not completely immune to the effects of these disasters, their body will be more durable to try endure better than others, but they're not completely defended from being like cooked by a wildfire or something 💀💀)

Possible Hero/Villain names -

(The first few names are mainly for oc's who mostly use one specific attack 💀💀)
Stormy Weather (Tornado, snowstorms etc)
Rainy Day (Acid rain)
Snowfall (Avalanches, snowstorms etc)
Natro Disastro (Sounds a bit weird but oh well)

Extra -

** I REEEEAAALLLY intended this to be a villain quirk for the record 😭😭😭
** A list of the disasters they can create is: Tornadoes, avalanches, forest fires, acid rain, snowstorms, earthquakes and tsunamis
