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.
To be fair to Boku No Pico, its creators initially meant it to be hentai. This means they never approached the series with a good storyline and compelling characters at the forefront of the planning stages. Even still, this does disservice to hentai that actually possess good plots, and Boku no Pico is simply bad regardless of its sexual subject matter.
Boku No Pico follows a twenty-something who tries seducing a 15-year-old who looks about nine years old, and it basically illustrates this story through uncomfortable material designed to appeal to predators. Yuck.
In the world of anime, the premise of cute, big-breasted high schoolers enlisting in the military actually sounds like a potential sleeper hit. Unfortunately, Skelter Heaven fails to turn this fan service into an anime worthy of any fandom whatsoever. This poorly animated travesty is half training exercises that make boobs jiggle, and half totally illogical military responses to a giant alien squid floating over Tokyo.
This show boasts a shocking 1.9 rating on MAL, which means few people have anything good to say about it. If you want to watch it anyway, godspeed.
Two brothers who transform into cats must solve the mystery of a demon plague that inexplicably involves tentacles. If this sounds like a thinly veiled excuse to draw some adult material, it absolutely is. The whole transforming-into-a-feline trope that sets Dark Cats apart from other shows isn't even capitalized on, as the characters spend half the series chasing demons, a task better accomplished in human form.
The voice acting is awful, mainly because the actors keep pausing in the middle of sentences for no reason. Maybe they, too, cannot believe Dark Cat actually got made into a real series.
Very few shows pull off making the main character a rapist and then have him remain sympathetic. Berserk arguably pulls it off because Griffith is such an intricately developed character, and the anime fleshes him out without excusing or diminishing his attack on Casca. Wounded Man, a five-episode OVA from the '80s, utterly fails at this.
Not only is protagonist Baraki a totally generic "bad boy" with few redeeming qualities, he sexually assaults a reporter named Ryuko and beats up her male crew members in the first episode. Apparently, this is supposed to warn them that Brazil is so horribly dangerous a Japanese person should never set foot there.
Even worse, Ryuko and Baraki end up falling in love, even though he, y'know, assaulted her. Wounded Man deals in the kind of '80s bigotry that culture left behind for a reason.
