Plenty of popular and critically acclaimed anime series exist out there, but even the finest of shows fail to completely overshadow the sins committed by the worst anime of all time. Just like Hollywood, the anime industry often invests in ventures that don't just flop, they bring John Carter-levels of shame to the medium.
Bad anime dubs can blame mistranslations for their downfalls, but the terrible anime series below have nothing to blame but their own reflections. Anime like Mars of Destruction, Boku no Pico, and Garzey's Wing apparently got storyboarded, animated, and voice acted without anyone involved in the process wondering whether or not they might be making bad anime.
Even the most hated anime characters can rest easy knowing they likely do not appear in the worst anime series ever made. In order for someone to appear on that list, they would need to be in an anime people actually enjoy watching. These anime are, unfortunately, not the "worth watching" type.
