you can decide what it can do, you can also decide how you find it in your description

a ray Gun that turns whoever it hits evil for as long as the person who got zapped believed they're evil, a causer of mischief and that they have the right to be (which they may or may not do have) once they question themselves though they will snap out of it and the effect will no longer work on then, if they get hit again, they either think they're evil again or they become resistant, most however mostly give in again, because deep down…they want an excuse… the origin of the RayGun is unknown (unless the user says otherwise) possible story 1: A friend of yours found it and accidentally zapped you possible story 2: a stranger kidnapped you possible story 3: your option whatever you choose, just know that you can be anything you want, male, female, plastic cup- anything this is probably cringe-
