Why These Anime Work for All-Star Superman Fans
These series resonate through shared DNA: power as burden (Casshern Sins, Yuki Yuna), legacy-driven growth (Ultimate Muscle, Kenichi), and moral complexity (From the New World, Ergo Proxy). They prioritize character depth over spectacle, using unconventional settings—post-apocalyptic wastelands, psychic dystopias, or historical battlegrounds—to explore heroism’s human cost. Unlike mainstream hits, their underrated status stems from niche appeal, but their thematic richness offers profound alternatives for fans seeking substance beyond capes.
