IDW Publishing's Godzilla: Legends. I do love me some Godzilla. But these are going to be stand alone issues where you don't really have to get into a whole back story about the monsters etc. IDW can be found Here
OSR idea tie in
I've used the lone back story adventure idea for years. Instead of the characters all meeting in a tavern. I've had the villain creaming a couple of the PCs loved ones & letting them fall together then tying it all up at the end of a campaign with the final battle. There's some awesome ideas in these comics for a post monster or apocalyptic game if you look. Anyhow here's the plot:
