scott mccloud (of Understanding Comics et al.) did this hilarious one-shot called Destroy!! in 1986. he says on his site:
After Zot! finished its first ten issue run in late '85, I took a year and a half break (not entirely voluntary, since the book was losing money at the time) and, apart from moving office furniture, I also decided to do a giant-sized one-shot filled with nothing but pure senseless violence from beginning to end.
I got the idea when I first heard people complaining about a Marvel comic called SuperBoxers and claiming that it was "nothing but senseless violence from beginning to end." I thought this sounded cool, but was disappointed, upon acquiring a copy, to discover that SuperBoxers included a plot, characterisation, and other distractions. It wasn't PURE. Destroy!! was my attempt to get it right.
