I have Quirk ideas.

Rewrite: This Quirk allows the user to rewrite a certain aspect of a person's Quirk - like if a Quirk damages a person's body in some way, the Rewrite user can rewrite the Quirk to not damage their body as much. To activate Rewrite, the user must first physically touch the person they wish to help, speak their name and the name of their Quirk, the aspect of their Quirk they wish to change, and how they want to change it. The drawback is each use of Rewrite causes neurons in the user's body to die, limiting their body movement.

First Letter Basis: This Quirk allows the user to take on a different first name every 24 hours, and the first letter of the name they chose dictates a wide variety of objects they can summon. Size and quantity does not matter. They can only summon items that begin with the same first letter as their first name, and they must decide beforehand how much of that item they need, because once that item is summoned, they cannot summon it again. Once a first name is used, they can only use a name with the same first letter 48 hours later.

Insane Companion: This Quirk allows the user to partake in any delusional fantasy of an unstable person within 10 feet of them. They can interact with the fantasy and basically become a friend that is equally unstable to the insane person. However, this Quirk cannot be turned off, leading to a rapidly devolving sanity of the user, as they aren't sure what is reality and what is fantasy.

Bloodhound: This Quirk gives the user the unique tracking skills of a bloodhound without any physical mutations. They have heightened hearing and smell, and once they have a scent, a colored trail lights up in their vision that guides them directly to whoever they're tracking. The only drawback is they're sensitive to high pitch noises.

Clear View: This Quirk causes a strong and wide nuclear energy to emanate from the user's eyes, disintegrating anything and everything they see - including people. It destroys everything so the person has a clear view of nothing but the sky. As their field of vision moves, so does the energy and the field of damage. The energy cannot be turned off, so a heavy duty blindfold is needed at all times.

And my personal favorite:

Flaming Eye: This Quirk causes a strong blue flame to emanate from the user's right eye, causing a black sclera. The user has partial control over the flame and can guide it to strike or spin its edge fast enough to draw in air, which causes enough friction to grab or pick up items. The flame can become a liability in enclosed spaces, and over exposure of the flame can lead to painful dry eye; constant use of an eyepatch is mandatory.
