Though it may not seem like it to some, Bastard!! is one of Shounen Jump's best selling manga series of all time. Having debuted in 1988 and still running today (no matter how infrequent), this dark fantasy gained popularity over the years despite itself. Manga featured in Jump publications are typically crated to appeal to either a young or extremely broad audience. Bastard!! broke the Jump mold its copious amounts of sex and violence, but was not punished for it whatsoever in terms of sales., While all of this may be unusual for a Jump published work, it is somehow appropriate for a dystopian and highly heavy metal influenced work. And when I say it's heavy metal influenced, I mean that in every possible way. The main character, Dark Schneider, is named for German heavy metal vocalist Udo Dirkschneider (of Accept and U.D.O.). The world itself is named Metallicana (obviously a play on Metallica), and more characters and spells than you can count have names that are references to well known heavy metal and rock musicians: Lars (Lars Ulrich of Metallica), Bon Jovina (Bon Jovi), Guns N' Roses, Whitesnake, Anthrax and more. We even get into the more obscure with the character Dai-amon (a reference in both name and appearance to heavy metal vocalist King Diamond, of both Mercyful Fate and his own solo work) and Abigail (most likely a reference to one of King Diamond's most well known albums of the same name).
