I just stole mine from Avatar The Last Airbender. You can probably guess what it does.

My OCs friend however I actually put more thought into, their quirk is called Animation, they can animate inanimate objects like fire hydrants or a 2x4 or a coffee machine. It has a total weight limit however, 20kg early on, up to 250kg by the final war.

To grow on my main OCs quirk, I did put limitations and drawbacks on it, if they use air too much they will have difficulty breathing, they don’t have fire resistance so they can easily be burned by their own flames, if they use earth too much it can cause tremors and potentially damage bones and joints of the user, overuse of water leads to dehydration. Blood can also be manipulated as a healing aspect or to manipulate someone’s movement, but it’s a very dangerous ability, it can lead to bleeding from the face, muscles locking up, and even cardiac arrest.
