It’s not exactly stand-alone, but Garth Ennis’ Punisher MAX run is incredible, and it takes place in a very grounded alternate reality without any superheroes so it really does feel like it’s own thing.

The Goon by Eric Powell is also really fun, it’s kind of hard to describe but it’s very funny and has some great art, just don’t follow Powell on Twitter.
