Production and Reception Notes
While “Immortal Bloodbath” was praised for its engaging character perspectives and continued exploration of the One-Punch Man universe, some critics noted inconsistencies in the animation quality from J.C. Staff, a recurring point of feedback for Season 3. The season’s animation has received significant backlash from audiences, with some describing it as low-quality, leading to intense criticism that reportedly caused the season’s director, Shinpei Nagai, to deactivate his social media accounts. Despite these production concerns, the compelling narrative and diverse character interactions continue to keep viewers invested as the season progresses towards its climax. The episode’s events further develop the Monster Association arc, adapting key moments from the manga and highlighting the struggles and triumphs of the Hero Association’s elite members against formidable monstrous threats.
