Baiorensu jakku: jigoku-gai-hen
The series takes place in the ruins of the Kanto region, after a massive earthquake (which in the OVAs was triggered by a Comet strike) dubbed 'The Great Kanto Hellquake'. Cut off from the rest of the world, The survivors of the disaster are divided between the strong and the weak. Violence Jack is uncovered amongst the rubble and demolished granite by the inhabitants of a ruined city, asking him to help the weak people and helping them destroy what, in most cases, are the strong groups commanded by killers and rapists (this is the story line of "Violence Jack: Evil Town"). In the three OVAs, Jack is requested to help different groups, such as the Zone A (later he ends up helping Zone C women) or a small town, as shown in "Hell's Wind". As for the manga, the stories change drastically, the first being the story Violence Jack helping a group of female models in a tropical forest in Kanto by possessing a boy living in said forest in order to fight off a roving tribe of bandits. Even though Jack contains the figure of a ruthless, evil character, he always helps the weak section of people, in trade for nothing.
When it was originally published there were several hints that pointed out the relationship between Devilman and Violence Jack. The final chapter reveals that the apocalyptic world in Violence Jack is in a world re-created by God. Satan (Ryo Asuka) is punished by being constantly humiliated by Slum King (Zenon). Jack is actually Akira Fudo, and is one of three parts that form Devilman, the others being a child Jack and woman Jack, both of which were normally seen as birds around Jack from time to time. They merge in order to stop the recently awakened Satan. This time Devilman manages to stop Satan.
