I think the German dub is the best. It fits perfectly the personality of the characters. My favorite is Genos, he sounds way too serious and epic! The worst one is the english one. It's just trash
French one is the best ! The voice actor for Saitama is a french rapper named Orelsan, and the voice actor for Genos is so good! I love his "INCINERATION"
japanese is very fitting, as always french was pretty good, genos's incinerate in french was actually so damn cool english is somewhat decent, still nice though i couldnt hear spanish, but pretty cool too genos in german sounds like hes more serious, saitama in german is goofy as always what the fuck did he say as incinerate in german? that sounds so ai generated
