Violence Jack: Hell's Wind-hen

Insanely violent motorcycle gangs terrorizing small towns and wreaking havoc indiscriminately 

Both anime depict events happening in a post-apocalyptic world. They both feature violent motorcycle gangs and contain a lot of gore and nudity. Also, both anime are created around the same period. 

Great gory titles. Genocyber shows people being mutilated by mecha, and Violence Jack shows free violence and rape. 

Both are based on manga from Go Nagai and are set in the same universe. However, you don't need to watch Devilman to watch Violence Jack. They both have a similar dark and gritty tone. As well as similar art and a similar vibe. Violence Jack and Amon: The Apocalypse of Devilman are both set in a world of despair and mayhem. They are also both action-packed anime with lots of blood, gore, and gratuitous nudity. However, Violence Jack contains graphic scenes of rape while Amon: Apocalypse of Devilman doesn't. If you like one, you should enjoy the other.  

Both anime are created around the same period (late 1980's-early 1990's). Both are very similar in tone and content with a dark and gritty atmosphere. They are also both action-packed anime with similar animation and a similar vibe. Violence Jack and Urotsukidoji: Legend of the Overfiend are also both famous for being quite disturbing and contain similar levels of graphic scenes of violence, blood, gore, nudity and rape. However Violence Jack has no tentacle rape though. If you enjoy one, you should like the other as well. 

While these two anime take place in different settings, both are action-packed anime with a dark and gritty atmosphere. They are both filled with violence, blood and gore. The main protagonist (Guts in Berserk and Violence Jack in Violence Jack) in both titles have a badass personality and wields a powerful weapon. They are both not afraid of anything and will kill anyone that stands in their way. Berserk has a better story and better character development than Violence Jack. However, they are both are very entertaining to watch. If you like one, you may like the other.
