These were just some quirk ideas for different my hero fanfics I might do tell me if you guys like them and give feedback if ya want

Sound booster

Type emitter

Allows user to amplify sound they hear and use it to create sound waves that the user is able to can be used to and back with lower frequencies or render someone unconscious with higher frequencies. The drawback being intense earaches and loss of hearing for 5 hours if overused.

Inspirations

An idea I had while watching a jet-set radio video and Kyoka jiros quirk.

Pixil

Type emitter

Allows the user to generate pixels that can be shaped into things as long as the user does not exceed a pixel limit and has memorized blueprint or a drawing in simpler creations what exactly their making, for example, a sword would just need a simple sketch with some notes on its characteristics while something like a gun or moving arm would need a blueprint with a lot of detail. If the user exceeds there pixel limit whether by making something too big making to many things or making something extremely complicated the user will suffer from extreme headaches

And bleeding from the nose.

inspirations

Momo Yaoyorozus quirk and borderlands.

Elemental absorbance

Type transformation

It allows the user to absorb elements through their hands to augment their body until, for example.

fire gives heat resistance and the ability to create flames.

water allows for water breathing and hydro kenosis.

earth allows the user to sense vibrations and manipulate earth.

air allows for better agility and air manipulation.

electricity allows for electromagnetism and the ability to produce electricity.

and ice gives cold resistance and the power to generate ice.

the downside. the user is limited to one element at a time and has a limit to how long they use the powers for and loses it faster with prolonged use as well eath element causes its own problems with prolonged use

Fire causes severe burns.

Water leads to dehydration.

Earth can cause bones to become brittle.

Air can make it hard to breathe.

Electricity causes muscle spasms.

And ice causes frostbite.

Avatar the last air bender and rogue from the x men

Turbine

Type mutant

The user has turbines on their for arms that allow them to manipulate wind and air.

Overuse leads to overheating and may cause the turbines to jam.
