Hellsing is a manga series written and illustrated by Kouta Hirano. The series chronicles the efforts of the mysterious Hellsing organization as it combats supernatural and vampiric forces that threaten the United Kingdom. The series largely follows Alucard, a powerful vampire in service to the Hellsing family, as the organisation is faced with undead foes, a rivalry with the Vatican, and an eventual impending war with the rogue remnants of a Nazi battalion. Many of the characters in Hellsing were based on concepts from Hirano prior works as a freelance manga artist.

Hellsing Organization The protagonists of the series are the members of the Hellsing Organization, a clandestine British royal order led by the Hellsing family that is tasked with defending the United Kingdom from supernatural threats.

Alucard

is a powerful vampire in complete service to the Hellsimg organisation. Alucard is violent, sadistic, and masochistic, taking a disturbing amount of pleasure in viciously ripping his enemies apart. He's also highly egotistical, taking pride in his abilities while looking down on both opponents and allies. Despite his methodical behavior, however, he strongly admires and respects humanity for their will to fight for their lives, something that he gave up on when he was a human himself, and he ultimately devotes his servitude to the Hellsing organization to protecting the innocent. Alucard is an exceedingly lethal combatant, even unarmed, due to his extensive supernatural abilities and strength. He is strong enough to tear a human body apart with ease and move faster than the eye can see. He can regenerate his body after taking any fatal damage, even if he was decapitated, split in half, or reduced to a pile of flesh and blood. Alucard can also shapeshift into whatever form he chooses. when he drinks his victim's blood, he can absorb their soul as well, obtaining their memories and converting said victim into an extension of himself known as a familiar. Other abilities include telepathy, intangibility, teleportation, telekinesis, and hypnosis. However, he also uses various weapons in battle. Weapons include swords, machine guns, and traditional vampire-slaying tools such as stakes and crosses. Alucard also has two signature weapons: a pair of intimidating, high-powered semi-automatic handguns named the .454 Casull and the Jackal.

Seras Victoria ;

is a young, strong-willed, empathetic policewoman who is turned into a vampire at the beginning of the series and then serves as Alucard's assistant, dubbed "Police Girl" by Alucard. Often, she is at odds with Alucard due to his preference for bloodshed and her refusal to fully accept her vampirism. She acts as the viewpoint character in the series. A character similar to Seras, Yuri Kate, is in its prototype version, The Legends of Vampire Hunter.

In the series, Seras is originally a police officer who, with her squad, is sent to the village of Cheddar. A vampire has taken control of the town and turned its inhabitants into ghouls. When Alucard appears, she is taken hostage by the vampire until Alucard shoots both of them, killing the rogue vampire and almost killing Seras. Alucard offers to turn Seras into a vampire to save her from dying, which she accepts. Then, she assists the Hellsing Organization against the increased vampire attacks. After Millennium declares war, she and the Wild Geese defend against Zorin Blitz's assault on Hellsing Manor, killing off most of the vampire soldiers before taking on Zorin herself.

Seras' past is revealed during Zorin's illusion trap. Her father, a police officer, "gets in too deep" during an undercover mission. The group he has infiltrated traces him back to his home and brutally murders him and his wife. A distraught Seras charges and stabs one criminal in the eye with a fork. She is then shot in the gut and thrown against a bloodstained wall. The flashback ends with Seras seeing one of the criminals having sex with her mother's corpse. After having her arm sliced off, her life is spared by consuming Pip's blood. Drinking Pip's blood transforms her into a full-fledged vampire, with a shroud of energy replacing her arm. Pip becomes her familiar. With her newly acquired strength, she can kill Zorin. She leaves the manor and meets up with Integra, who is being escorted by Alexander Anderson and his soldiers.

She is later shocked at Walter's return as a vampire, seeing him as a father figure. Despite now being enemies, she thanks Walter for everything before boarding the zeppelin with Integra to face the Major. On the ship, she does battle with the Captain before finally managing to kill the werewolf. Later, she and Integra witness the evil Major's grand plan to kill Alucard as he disappears. She is then able to shatter the protective glass that shields the Major allowing Integra to finish him off. With the war now over, Seras carries Integra back to the remains of Hellsing Manor. In the epilogue, Seras has become Hellsing's highest-ranking vampire after Alucard's supposed death. After he returns, she is finally excited to be reunited with her master.

Integra Hellsing ;

is a 22-year-old noblewoman member of the Protestant Knights who is the head and last member of the Hellsing family, the Bureau Director of the Hellsing Organization, and the current master of Hellsing's vampire, Alucard. Integra is usually emotionally collected, rarely allowing them to get in the way of business. However, she is sometimes prone to fits of anger. The Hellsing family is "on a mission from God", and she values her duties to protect the United Kingdom and the Anglican Church above everything else. For her, failure is not tolerated, especially her own. She runs the Hellsing Organization with charisma and patriotism, and she is one of the few people who can stand up to the force of Alucard's personality and command his respect. As a child, she develops a deep sense of duty to Hellsing, not standing for anything that may threaten her or her organization. Being the first matriarch of Hellsing, she struggles to maintain respect from members of the Queen's government known as The Round Table who often question her judgment.

During the Valentine brother's invasion, Integra takes full responsibility for allowing the vampires to break into the Manor and personally slays all personnel who turned into ghouls because of it. After Millennium declares war against England, she and Walter flee from the attacking vampires with Walter hiding behind to allow her to escape. She soon meets up with Alexander Anderson and his men who reluctantly agree to accompany her through the city. After witnessing Alucard and Anderson's final duel, she is shocked to see Walter return as a genetically modified vampire. Integra and Seras leave for the Major's zeppelin, but not before declaring Walter an enemy to the Hellsings and ordering Alucard to kill him with no remorse. She makes it to the Major but is unable to kill him due to a protective glass wall shielding him. After this she witnesses the Major's plan unfold, resulting in Alucard's supposed death. After Seras shatters the major's defenses, Integra finally shoots him in the head, but he shoots her in the eye at that same moment. With the battle over, the two return to Hellsing Manor.

In the epilogue set 30 years after the war, a now middle-aged Integra laments about finding someone to take over for her when she dies. Later that night Alucard returns, having managed to regain his sense of self but with the cost of having to take a long time to do so. She offers Alucard some of her blood, welcoming him back after decades of his absence.

Walter C. Dornez ;

is a member of the Hellsing Organization who also serves as the Hellsing family retainer, a job that he has maintained for most of his life. His ability to use high-velocity monomolecular wires with incredible skill and precision earned him the nickname the "Angel of Death". During the events of Hellsing: The Dawn, Walter accompanied Alucard in the storming Millennium's base during World War II in Warsaw, Poland where they put end to the organization's first attempt at create an army of artificial vampires. However, due to his fears of being forgotten and The Major forcibly drafting him after witnessing his abilities, Walter became a double agent of Millennium within the Hellsing Organization's infrastructure in the aftermath of the war.

Decades later, Walter arranged for Integra Hellsing to unseal Alucard and make the vampire her servant. Walter carries on his duties as the current Hellsing head butler while providing special weapons for use by Alucard and Seras Victoria. Despite his advanced age, Walter can still fight his way through hordes of the living while helping Integra make numerous difficult choices when Alucard harms innocent humans in order to achieve mission objectives. While he appears to accept his age with proud resignation, it is a façade to hide his fear of being useless and desire to be a true Angel of Death.

Once Millennium begins its attack on London, Walter is retrieved by the Captain to be made into an artificial vampire to prepare for his fight against Alucard, being restored to a much younger form. Appearing while crushing what remains of the deceased Alexander Anderson underfoot, Walter slaughters Yumie before facing Alucard in a duel. During the duel, it is revealed that Walter's vampirism was hastily conducted as he lacks the ability to regenerate normally like the Last Battalion while also growing younger. Having regressed to his teenaged self and stating he risked everything to prove his worth against the vampire, Walter loses his chance as he is forced to watch Alucard fall into The Major's trap and cease to be after unknowingly absorbing Schrödinger. Entering the Hindenburg II after dealing with the vengeful Heinkel Wolfe, Walter kills the Doctor before being consumed in the inferno caused by the zeppelin's explosion. Walter's prototype was in Daidōjin Monogatari alongside Heinkel.

Pip Bernadotte ;

is a French man with an eye patch over his left eye. He is from a long line of mercenaries and leader of the Wild Geese. His ancestors were members in for six generations. While experienced with the AK-74 as his weapon of choice, Bernadotte can be a narrow-minded womanizer with a compulsive smoking habit. Bernadotte and the Wild Geese are hired by Walter after Hellsing's military is slaughtered by the Valentine Brothers and their Ghouls. While Bernadotte and his men initially refuses to believe in vampires during his first debrief, they are all convinced shortly after meeting with Alucard and Seras. Soon after, while flirting with Seras on a regular basis, Bernadotte supports Alucard and Seras during their mission in Brazil where Pip and Seras start to bond.

During Millennium's attack on London, Bernadotte and his men suffer losses as they and Seras attempt to defend Hellsing manor from Zorin Blitz's forces. Though already severely injured, Bernadotte tries to save Seras from Zorin before the Millennium member impales him. After finally getting Seras to kiss him, Bernadotte tells her to drink his blood to save herself by awakening her full vampire abilities. The act results with Bernadotte becoming Seras' Familiar as his memories enable her to resist Zorin's attack before killing her. Later, during Seras' fight with The Captain, Bernadotte makes his presence known as he advises Seras in her fight before manifesting from her body to land the deathblow for his Seras. Unlike others that have been turned into familiars, Bernadotte's personality remains intact as shown when he communicates with Seras, In the series' epilogue, as Heinkel hurts Bernadotte so the other Iscariot members can see, it is revealed that Seras has Bernadotte's function as the restored Hellsing manor's security system in the form of a shadowy mass covering the estate.
