YMMV / Last Bible

• Complete Monster (Last Bible III): Banipal, aka the Soul Eater, is a sorcerer who experiments on humans and sapient beasts, leaving them in a state of constant agony, in his pursuit of immortality. In the present, Banipal hunts the Shadow Walkers in orders of Ben-Shoah in exchange for the Necronomicon. When the people of Baruch, home of a Shadow Walker, found and took care of a disguised Banipal, he used the opportunity to massacre the town and create monsters that would brutally murder children, sometimes as sacrifices, of nearby towns that Banipal plans to destroy as well, devouring the souls of their last guardians to send a message. Killing Miss Carol when she tries to stop him, Banipal survives the destruction of his lair and continues his atrocities, killing Jonathan's beast partner and performing lethal experiments on Harry before trying to experiment on the protagonists.
• Magnificent Bastard: From III:
  • Ben-Shoah is a survivor from Blantica who seeks to rebuild his society and prevent its mistakes by controlling Gea usage. Becoming part of the Council of the Polisian States, Ben-Shoah ends the Polisian War by creating the Phelesteau Tower to farm the Gea of eternally sleeping people caught in a pleasant dream. Initially sparing the Shadow Walkers after sealing their unconvenient memories until Alek Mecenas rebels, Ben-Shoah orders their persecution and hires the cruel Banipal, causing innocent deaths and exiles. Meanwhile, Ben-Shoah consolidates his power by using fake news and organizing events to show his charming personality to the public, going so far as to liberate prisioners after the heroes win a tournament. When the Polisian Council rejects Ben-Shoah's proposal to invade the Magoku Kingdom, he rallies a mob to become dictator and promises to not let any Polisian die, fulfilling his promise by using the Archweapon to annihilate Magoku's best warriors and force them to surrender, succeeding at taking over the world. Even after the destruction of the Arch-Weapon, Ben-Shoah takes it as a minor setback until a repentant Polisian Councilmen helps the heroes to defeat him.
  • Alek Messenas starts as a member of the Shadow Walkers, war heroes of the Polisian States. In the past, Alek discovered the truth behind the Phelesteau System and got his memories sealed for years until the seal was accidentally broken. Rebelling against the Polisian States, Alek's family is murdered during a assasination attempt, making him travel to the Gate of the Underworld to obtain power and have his revenge. Becoming a vengeful spirit, Alek would form a demon army that would challenge the Demon Lords and use his recently murdered Shadow Walker friends as his generals. Now deciding to take revenge on humanity as a whole, Alek would succeed at stealing the Book of Belial and invade the Mortal World, stunning Lucifer himself. Alek's demon army would then proceed to depopulate the planet while Alek boasts of his victory and challenges humans to defy him. When Ciel defeats him, Alek accepts his second death and congratulates the "Children of the Force".
