As for anime, Astroboy is pulp as hell, so is Golgo 13. Might fit your taste
After I said I wasn’t a big anime guy, a few people have given me recommendations.
Golgo-13 sounds awesome, like a hardboiled men’s adventure novel hero from the 1960s, only more far out. I appreciate the recommendation. I’ve always felt that men’s adventure heroes like Pendleton’s Executioner, to say nothing of the “Special Forces/Green Beret” gun porn men’s adventure novels of the 1980s, grounded themselves needlessly; they should embrace the fact their characters are slightly superhuman and theatrical, the way the Shadow did in the 1930s (which is why I tend to enjoy the pulp heroes of the 30s more than the men’s adventure heroes of the 80s). So, just conceptually, I like the approach.
Astro Boy though, violates one of my two ironclad rules: no talking animal sidekicks, no cute little kids.
