Brand of Justice

If I become a vigilante, I would want to use special brass knuckles with my insignia on them (similar to John Constantine's cross knuckles) and somehow electically heat the logo part so that when I punch my enemies, they are branded with my logo. That also allows me to make puns about my harsh brand of justice. I could also use this as a costumed criminal, but then I would have to talk about my brutal brand of something else.
