Transmetropolitan (comic book) by Warren Ellis is everything you asked for, except the Punk element. Spider Jerusalem is a journalist that embodies everything about the aspect, though. He’s exceedingly anti-authoritarian, exists to antagonize societal and cultural norms, loud, in-your-face, and pretty much is everything punk except for the mohawk and circle pitting for 3-chord rebellious anthems.
I can confirm. As a person who had a chihuahua for 11 beautiful years, he yearned for the most violent death of any and all that displeased him, which was anything bigger than him.
