In a post-apocalyptic Earth, two powerful forces are destined to clash. Following a catastrophic nuclear war, humanity is nearly wiped out, giving rise to a new world where magic and primitive technology coexist. From this chaos emerge twin brothers, Avatar and Blackwolf, who embody good and evil, respectively. Avatar becomes a wise and benevolent wizard, seeking to heal the world through peaceful means, while Blackwolf delves into ancient technologies and dark enchantments to rebuild an army of mutants and demons. As Blackwolf rises to conquer what's left of the shattered earth, using recovered Nazi propaganda films to inspire his troops, Avatar realizes the dire threat posed by his brother and prepares to confront him.

Avatar is joined by a small group of allies: the warrior elf Weehawk, the fairy princess Elinore, and a former assassin robot named Peace. Together, they embark on a perilous journey through treacherous lands filled with malevolent creatures and ancient dangers. Their quest is not only to stop Blackwolf's malevolent campaign but also to destroy the source of his newfound power. As they venture deeper into enemy territory, they face numerous trials that test their resolve and unity. The stakes are nothing less than the survival of what remains of their world, as forces of magic, technology, and sheer will collide in an epic struggle between good and evil.
