This is a list of characters of the manga series Bastard!!.

Main characters /

Dark Schneider (noted to be named after Udo Dirkschneider) is the most powerful wizard, revealed to have been created during the final days of the Old World by the Ten Wise Men of Europa as the pilot of the "Dragon Knight", a mecha created to destroy Anthrasax. Following the cataclysm, Dark spent the four centuries cheating death while seeking world dominion and amassing a large harem. Fifteen years prior to the storyline, Dark amassed the Dark Rebel Army from thousands of wizards and warriors, led by his Riders of Havoc, Arshes Nei, Gara and Kall-Su. Dark was defeated by Metallicanan prince Lars Ul Metallicana, reincarnating himself inside the body of Lucien Renren before his spirit is sealed within the newborn by Geo Soto Noto, causing Lucien to grow up into different person. When the reformed Dark Rebel Army commenced a campaign to resurrect Anthrasax, Dark's seal is broken as he becomes a reluctant ally of Metallicana while winning back his Riders of Havoc before resuming his ambition. While originally requiring Yoko to kiss Lucien to manifest, Dark gradually gains the ability to freely take over his host. After losing his battle against Anthrasax, Dark is cast into the depths of the upper levels of Hell where he encounters the fallen angel Satan. Satan reveals to Dark that he is a reabsorbed fragment of his brother Lucifer, the first fallen angel and Lucien's true identity, who is destined to lead demons and mankind to war against Heaven, but Dark refuses to align himself with Hell and then is thrust into battle with the High Commander of Hell, Porno Diano. Four years later, he returns to Earth and fights alongside the Seraphim against the devil Konron (Conlon). His body is destroyed by Konron's Trelldor Spinning Fist attack, but his head survives.

Yoko is a strong-willed and somewhat temperamental redhead, daughter of the Geo Soto Noto, a chaste virgin, self-appointed guardian and friend of Lucien. The primary love interest of Dark Schneider, she is the first to use the "virgin's kiss" to awaken Dark. Having undergone priestess training she does not show any magical talent until later in the manga (acting as the party's cleric) and never in the OVA. Despite this, she is the one person that DS fears and (mostly) respects. She disappeared during the four-year series break, apparently being killed during the fall of King Crimson. In the same time period, a woman with the same appearance and known as "Lilith" appeared alongside the Kings of Hell. She was found near the borders of the Lethe and seems to have some memories about DS.

Four Divine Kings

Gara is a master of Ninjutsu who became a member of the Dark Rebel Army's Divine Generals after impressing Dark in an assassination attempt. He commands a sword which can draw its life force directly from the swordsman, allowing almost unbeatable magic attacks. Unfortunately, the strongest attack is usually fatal to use. When Gara learned of Dark's resurrection, he abducted Yoko and forced Dark to confront him at his keep in a battles that caused them to each lose an arm. Though defeated, Dark wins back Gara's services after restoring his arm and keeping his men alive during the keep's destruction.

A half human, half Dark Elf. Her name is a reference to Whitesnake. Kept as a slave by the Wood Elves, she is now raised by Dark as his adopted daughter and eventual lover, following her tribe abandoning her. As one of the Dark Rebel Army's Divine generals and founding members, Nei is well aware of Dark's abilities and revived some ancient magic used by her followers. When Nei's loyalty to the Dark Rebel Army comes to question, she allowed herself to be cursed by Abigail with the spell Accused. When Nei confronts Dark, Lucien's spirit made Dark Schneider aware of what was driving his daughter to attack. DS was outraged and tore out his own heart to drive off the power of the Accused spell (later resurrecting himself). Arshes rejoins him at this point, and they destroy the advancing armies. After learning Kall-su's true colors, she is completely shocked and sad as she saw him as a friend, even though he never treated her and the others as friends.

Kall-Su was the second general of Dark Schneider; he commands the Ice-Falchion, a great sword, and is innately magically powerful. Kall-Su was born in a distant village, persecuted for his father being an Ice-Dragon in human form. It led to him killing his ashamed mother in self-defense and then destroying his village soon after. He was later found and adopted by Dark, treated as an indentured servant. He boasts extreme power and is capable of transforming into an Ice-Dragon at will. He destroys the entire city of Whiteos-Neiki with his spell, Vizkaya, which freezes everyone in the Kingdom into solid ice. After Abigail's defeat, Kall-Su is made into Anthrasax's thrall and used to track down Sheila to Crimson King Glory, but Kall-Su manages to be freed of Anthrasax's influence and joins Dark in facing the being. Kall, Nei and Gara figure out why "glowing beings of light" have started a war against them via ancient computers in an underground base. They discover that the Apocalypse is fast approaching and the beings of light are in fact angels sent from God to kill a third of mankind (those deemed sinful for worshiping false gods). One of the twelve elves of Europa (riding an abomination looking similar to a behemoth with human feet, and dozens of eyes) sees the three and is angered that they have discovered the reason behind the current events of the earth through his computer system. After calling forth many monsters, they do battle. Before the battle evens starts, however, they discover that their swords are going erupting with energy and seems to have lost their power. Four years after the battle on earth, Kall-Su is found to be blinded (apparently from the scars over his eyes and face). He says that his power has increased exponentially over the past four years, though he does not know why. It is eventually made clear to him through "The Mysterious Boy" that he is filled with the same power as Elijah and deemed worthy to be his successor. It is also said that he is the "true" king of Metallicana, and will eventually have to do battle with Dark Schneider alongside the "Mysterious Boy". Many people do not believe that he is Elijah's successor, namely the dwarf king Jeloy, who was armed with a mighty ax to repel this fact. He and his men, however, were stopped by Lars, thinking that he was truly Elijah's successor (as he is a well-known hero in the dwarven kingdom). He corrects their statement, saying indeed that Kall is Elijah's successor and was told to do the work of God. After leaving the dwarf kingdom, Kall-Su decides to go to the world of spirits to seek help and awakes a mighty giant from his frozen slumber. The giant curses him for violating "holy" land and says that he will have to die for his "sins". Kall claims that "death will not be enough to atone for my crimes in this world" and throws a ball of super-condensed water at the giant, throwing his Ice-Falchion at the ball to release a surge of water upon the giant, returning it back to captivity in a pillar of frozen ice. Nei approaches him and tells him that it's not like him to be so rash. The ground begins to rumble and a gigantic gateway appears before the two, Kall claims that he will journey to the realm of spirits to try to ask for help against the upcoming war on Earth. His name is a reference to Kal Swan of the bands Lion and Bad Moon Rising.

Abigail is a mysterious member of the Dark Rebel Army's Divine generals who appears after Dark's demise fifteen years prior, originally a scientist during the final years of the Old World as a member of Ten Wise Men of Europa who studied spiritual matter and played a role in Anthrasax's creation. After the fall of the Old World, Abigail traveled the new world before joining the Dark Rebel Army to orchestrate his scheme to facilitate Anthrasax's resurrection after ending up in the latter's thrall. He curses Arshes with the Accused spell, which forces her to obey him or her body would be painfully distorted into an immortal toad. He succeeds in breaking the three seals of Anthrasax, personally invading Metallicana while using the three Demonic Treasures. Despite nearly killing Dark's group, Abigail is purged of Anthrasax's influence while his defeat obliterated Metallicana Castle. In the "Requiem of Hell" arc, Abigail concealed himself in a robot body and joined Dark's allies in Iron Maiden as Angus Yarn. Following the angel attack on earth, Abigail converts his spirit into the mainframe grid system of the flying ark King Crimson Glory. There are clues that Abigail may be the "false prophet", the servant of the Antichrist mentioned in The Bible. His name comes from King Diamond's classic album, Abigail.

Metallicana

Lars Ul, whose name is a reference to Lars Ulrich of Metallica, is the prince of the kingdom Metallicana. He is said to be their greatest warrior, due to him having the ability to slay armies of thousands single-handedly. A portion of his power comes from the "blood of dragons" flowing through his veins, giving him the increased vigor, power and speed, as well as the ability to use the "Ki", or spiritual power of the dragon for his attacks. He wields the dragon sword "Heavy Metal", a translucent blade whose destructive can be further augmented by absorbing the "ki" of dragons. Fifteen years before the story starts, he fought Dark Schneider to a standstill as the latter has conquered most of the world at that point. This forced Lars to kill Dark by using the "Dragon Knight", but Lars is cursed since he used the Dragon Knight to kill Dark instead of its intended quarry, transforming him into a baby dragon with everyone assuming he died defeating Dark. In the form of a baby dragon, Lars sought to find a successor to the Dragon Knight before he was taken in by Gara as pet and then following Dark despite their history. Lars eventually regains his original form once Dragon Knight was destroyed by Anthrasax, revealing the truth of his curse. During the angel attack, Lars fights on against the angels using the power of the dragon. He is the last to stand his ground (as the Sorcerer Shoguns and Samurai were slain), though he eventually is killed by the higher ranked angels.

Named after the artist Jon Bon Jovi, Bon Jovina is the unfortunate Captain of the Guard of Metallicana. He is constantly being crushed by enemies, but appears to be quite durable, because he survives being smashed by a Hydra, pummeled by a Minotaur with a giant war hammer, flattened by two walls, and blasted through two walls by the Hurricane Sword. He greatly dislikes Dark but is very loyal to the princess. Currently, Bon Jovina is in the Halls of Gathering with the other races of half-humans around the world to decide what to do about the upcoming battle.

Princess of Metallicana and Lars's sister, she is strong and determined, but only somewhat magically powerful. She has been taken in by Dark's charms, even going as far as admitting that she "loves" him. She is also revealed to be one of the four seals of Anthrasax, sent away to Crimson King Glory for her safety after the three other seals were destroyed, but she dies during the battle between Dark and Kall-Su, freeing Anthrasax as a result.

The current, unnamed, King of Metallicana and father of Prince Lars Ul and Princess Sheila.

Yoko's powerful cleric father; he transformed and imprisoned Dark in the form of Lucien at the end of the Great War which occurred 15 years before the main storyline. His name appears to reference Jeff Scott Soto, former singer for Yngwie Malmsteen.
