|Cause of Death||
Klaus was an Old One, also known as a pure-blooded vampire. He is the ultimate big bad and villain of the entire series overall (although he is first featured and seen in Dark Reunion). Klaus is resurrected in The Hunters: Destiny Rising, on a mission to get revenge and destroy Elena and all of her friends. Klaus is the ultimate enemy to all of the main characters in the series, especially to Elena and Stefan. Klaus is a pureblood vampire, one of the 'Old Ones' who has never been a human, and he existed long ago before the pyramids were built, which was 2500 B.C. According to him, he fought in the Trojan war and helped cause the downfall of the Roman Empire. In the late fifteenth century, he lived in a village in Germany, where the people thought that he was the devil himself.
Klaus is Nordic in appearance, with electric blue eyes and short, close-cropped, platinum blond hair. He is described as being handsome although his features are often contorted in madness. He wears a dusty long tan coat. Personality-wise, Klaus is extremely deranged, and the line between his evil and his madness are very blurry. When pressed, he is deadly serious and reminds everyone about his unfathomable old age, but usually, he seems unnaturally chipper, and his evil deeds during Dark Reunion are tinged with irony. He refers to everyone as "sport." He writes "Goodnight, sweetheart" on Vickie's mirror after brutally murdering her and leaving the same song playing in her room. He nearly kills Stefan with the white ash wood spear that was intended for him. His mood changes from cheerful and amused to enraged in seconds. Despite his seemingly erratic and scattered personality, he appears to be a patient and methodical killer capable of elaborate plans. One day, a maid begged for his help to save her dying mistress, Katherine Von Schwarzschild. Klaus turned her into a vampire and instructed her on how to be malevolent and despotic.
Centuries later, Katherine thought that she killed him, but Klaus arrives in Fell's Church, where he helps Tyler become a werewolf. After that, he uses Tyler and his own enhanced vampire powers to play with the Salvatore brothers and their human friends. He murders Sue Carson, a friend of Bonnie and Meredith, and Vickie Bennett in an extremely violent manner. He offers Damon a truce if he will keep out of his way whiles he violently kills Stefan. Klaus also kidnaps Caroline Forbes and holds her hostage as bait to get Stefan to fight him. In the final showdown, all the weapons used against him fail. Stefan bravely faces Klaus in an attempt to battle him and defeat him to protect the people he cares about and the town of Fells Church. However, despite Stefan's bravery, Klaus about almost kills Stefan and also, nearly kills Damon as well until there is an intervention from Elena's spirit, leading an army of Civil War ghosts. The ghosts carry a screaming Klaus away, and his current whereabouts (and state of being) are unknown. Klaus is reborn by Ethan. Klaus awakens all the vampires he turned that are dead and creates an army. Klaus promises to kill Elena and all her friends for revenge. Klaus tries to kill Elena over and over again but fails. When Klaus drinks out of Elena he dies. It is reviled that Elena is the one that can kill the old ones by letting them drink from her blood.
Klaus is of unknown age, earliest memory is of carrying a bronze ax, placing his inception in the Bronze Age (4500 BC - 3200 BC). He fought in the Trojan War (1194 BC to 1184 BC), was part of Alexander the Great's army (336 BC - 326 BC) and witnessed the death of Julius Caesar on March 15, 44 BC, and in the wars that led to the Roman Empire's downfall (on the Germanic side) in AD 456. During this time, probably, he met and gained the confidence of a being named The Devil, with which, later, signing a pact. He then, probably, decided to stick around the general area of Germany. In the late fifteenth century, he lived in a village in Germany, where the people thought that he was the devil himself. One day, a maid showed up and begged for his help, because her young mistress was dying. That girl was Katherine Von Schwarzschild aka Katherine. He then turned her into a vampire, feeding her with his blood, saving her from death and making her much stronger than she had been in life, and Gudren used more of her connections to find Katherine a spelled lapis lazuli ring so that she could walk in the daylight. Nothing more is known about Klaus' whereabouts when, one day, in 1450, Katherine returned to the German village to find him, after faking her death in an attempts to get both Salvatore's brothers to reconcile by fooling them into believing she had committed suicide. The two then spent the next five century together. The books suggest that Klaus abuses her while teaching her to become a significantly tougher, stronger vampire, and over time with Klaus influence, she becomes power-hungry and insane, losing utterly her childlike innocence and naiveté. At some time, however, Katherine eventually attempts to kill Klaus, evidently believing that she has succeeded, but Klaus survived. His vernacular suggests that he's spent a lot of time in modern America, though - certainly enough to pick up slang like "sport" and use it comfortably and casually, and know (and use with effective irony) the song "Goodnight, Sweetheart." Probably during this time, on June 6, 1999, Klaus found the home of vampire hunter slayers Fernando and Gabriela Sulez and killed their guards with one blow. He then attacked Gabriela's parents, killing her mother and driving her father to insanity. Klaus then made her children, Meredith and Cristian, drink his blood, which presumably had a spell cast on it to start turning them into aging vampires without having to die. Their parents came home and Klaus tried to take the children, but Meredith fought back and bit him, so he let her stay and taunted her parents, saying to feed her a tablespoon of blood a week if they wanted her to stay alive. Klaus then sent them a picture of Cristian every June 6 (the children's' birthday) until 2006 when they were 10. In each picture, he had fully elongated fangs like a real vampire, but he was still getting older, whereas Meredith only ever had "kitten teeth" since she was only getting the bare minimum amount of blood to survive. On June 6, 2013, the Sulez family received another photo of Cristian, possibly indicating that he had been killed and turned into a full vampire by Klaus. When the news of Katherine's death reaches him, he decides to go to Fells Church to get revenge.
Throughout the Series Edit
Klaus showed up in Fell's Church in 2014, where he encountered Tyler Smallwood and reveals his true origin and identity. During a surprise party for Meredith's eighteenth birthday he helped Tyler kill one of Bonnie and Meredith's friends, Sue Carson, to trigger Tyler's werewolf gene, and then they drank her blood together from her chest. Later Stefan hypnotizes Vickie, who was present during the murder, who tells him that Sue was thrown out the window by a tall blond man with blue eyes. Vickie is certain the man will come for her and kill her next. Her belief is reinforced in the next few minutes while objects in her room start to move, lightning cuts through the sky, and the words “Goodnight, Sweetheart” appear written on her mirror with lipstick. Stefan gives Vickie vervain to help her resist Klaus’s influence and promises that they will all keep watch over her. The others realize that Stefan believes Sue’s killer is a vampire and Damon is left to guard the girl. Stefan then comes up with a plan that the rest followed. Meredith and Bonnie stage a loud argument during graduation. Meredith says she will go alone to Elena’s grave that night to lay a flower there. Their argument is overheard by the party intended to overhear it: Tyler Smallwood, who shows up and changes into a werewolf to attack Meredith. Stefan, Matt, and Bonnie are waiting for Tyler, though, and they appear and tie him up. They lead him to the ruined church and threaten to amputate a limb, which will have the effect of destroying his werewolf abilities unless he tells them what he knows. Stefan explains that he knows that the killer cut Sue’s chest to let Tyler drink her blood. The blood initiated Tyler into his hereditary powers as a werewolf. Tyler refuses to admit any involvement until Stefan feints with the ax. Hysterical with terror, Tyler tells them that the killer is an Old One, an Original vampire, who cannot be killed and can only be injured by one type of wood. Tyler doesn’t know what type. He also says that the killer plans an attack on Vickie that night. Klaus successfully killed Vickie and offers Damon a truce if he'll keep out of his way while he kills Stefan.
When Stefan and the others return to where they left Tyler, he is nowhere to be seen, probably helped by the same Klaus. Instead of going home, Stefan tries to contact Elena, with Bonnie's help. When she finds Elena in a vision, though, Stefan and Elena have only a few minutes together before the Old One shows up and begins to control Bonnie’s mind. The Old One identifies himself as Klaus, the vampire who turned Katherine. He destroys Elena’s appearance to hurt both her and Stefan, but Stefan refuses to turn away from his beloved and uses his own Powers to restore her appearance. Before Klaus destroys Bonnie’s dream-vision, Elena tells Stefan that one of Klaus’ victims will know how to defeat him: Meredith's grandfather is the person. To figure out the type of wood needed to kill Klaus, Meredith, Bonnie and Matt go to visit him and he just screams "white ash wood." On June 20, Klaus sends Stefan a package with Caroline's scarf in it and a note telling him to meet him alone to the Old Francher Place. Bonnie, Meredith, and Matt follow along, anyway, against Stefan's wishes. A confrontation occurs in the woods, with Klaus and Tyler fighting Stefan, Bonnie, Meredith, and Matt. Caroline is rescued. Bonnie knocks Tyler unconscious, but only after Tyler rakes Meredith’s leg to the bone and gives Matt a concussion. Klaus stabs Stefan multiple times to kill him slowly. Damon shows up and throws his own spear at Klaus, distracting him. Damon and Bonnie try to help Stefan, who is too badly wounded to save. Stefan asks Damon to promise to save the others, and Damon agrees when he can find no way to save Stefan’s life. The promise is made moot when Klaus reappears and hits Damon with lightning, knocking him unconscious. Klaus is about to kill Bonnie, who is vainly trying to shelter Stefan with her body, when Bonnie suddenly calls upon Elena. Elena’s ghost appears, along with the ghosts of the Civil War soldiers. The soldiers carry a screaming Klaus away, and eventually he is destroyed.
At Dalcrest College's campus, the special fraternity called the Vitale Society, which Elena's parents were involved in, is led by a vampire named Ethan. He reveals to Stefan that one of Klaus' descendants turned him and that he plans to resurrect the Old One at the equinox. He needs, however, the blood of his descendants to do this. Luckily, the gang manages to win the fight against the Society, but not before Ethan gets a vial of Stefan and Damon's blood. Meredith kills him before he can do anything. In the epilogue, it is revealed that Meredith missed Ethan's heart and he is still alive with both Salvatore brothers' blood and can complete the ritual as expected the equinox unknown to Elena and her friends.
Ethan and the Vitale Society are determined to resurrect the Old One. Klaus was later resurrected by Ethan Crane using the blood of vampires descended from him through Changing. He used more blood to resurrect Katerina and then used a vampire army to get revenge on Elena Gilbert. However, he was killed when he drank her blood, which had the power to kill Old Ones.
Personality + Physical Appearance Edit
Personality wise, Klaus is extremely sinister, sadistic, sociopathic, evil, vengeful and dangerous. He is highly powerful and is highly intimidating and threatening. Klaus is extremely deranged, and the line between his evil and his madness is very blurry. When pressed, he is deadly serious and reminds everyone about his unfathomable old age, but most of the time he seems unnaturally chipper, and his evil deeds during Dark Reunion are always tinged with irony. He refers to everyone as "sport," he writes "Goodnight, sweetheart" on Vickie's mirror after brutally murdering her and leaving that same song playing in her room, and he kills (or nearly kills) Stefan with the same White Ash Wood spear that was intended for him. His mood changes from cheerful and amused to absolutely enraged in seconds and he is very unpredictable. Despite his seemingly erratic and scattered personality, he seems to be a patient and methodical killer capable of elaborate plans. Klaus is very tall and very Nordic in physical appearance, with piercing electric blue eyes and short, close-cropped white-platinum blond hair. He is described as being very handsome despite the fact that his features are often contorted in madness. He wears a dusty long tan coat. Vickie Bennett describes Klaus' physical appearance in Dark Reunion as the following: "He wears...an old raincoat. It flaps around his legs in the wind. He makes the wind blow. His hair is blond. Almost white. It stands up all over his head. His eyes are blue - electric blue". Vickie also describes Klaus as very tall in stature and very handsome.
- Transcendent Vampire Physiology (also known as "Absolute Vampirism", "Divine Nosferatu Physiology", "Ultimate Vampire/Vampirism", "Vampire or Vrykolakas God Physiology", Vampiric Ascension, Divinity, or Perfection"): The ability to use the traits of a divine vampiric being. The most powerful variation of Vampire Physiology and a vampiric variation of Transcendent Physiology. The user with this ability either is or can transform into a Transcendent Vampire: a powerful vampiric being who has literally ascended to true godhood either through powerful magical feats or by divine intervention. In various forms of traditional folklore, vampires are often depicted as demonic beings who must feast on the blood of the living to survive and possess vulnerabilities to various things such as sunlight, garlic, holy relics, etc. However, Transcendent Vampires are arguably completely the opposite. Transcendent Vampires are often depicted as supernaturally attractive and possess an appearance identical to the one that they had in their previous life. They also appear to have an inherently mesmerizing aura to their presence. Many mortals or lesser beings may often feel an obsessive desire to be with the vampire in question or even follow and carry out their commands as mindless slaves. Another thing that makes Transcendent Vampires unique is that despite them appearing to be related to things such as dark magic or inherently evil aspects, they are actually in fact shown to be often associated with or even assisting a higher power. In fact, most Transcendent Vampires are sometimes seen preaching or more or less speaking of the relationship they have with the supreme being they may or may not have worshiped during their mortal lifetime. Overall, Transcendent Vampires are the supreme paragons of the species. They are responsible for maintaining the natural balance between vampires, humans, as well as other monsters. Due to the nature of their powers, they are capable of increasing their already amazing powers even further by absorbing various forms of energy. The user is thus capable of challenging most beings in existence.
- Vampire Lord Physiology (also known as "King of Vampires", "Vampire Lordship", "Queen of Vampires", "Lord of Vampires", "Lady of Vampires", "Master of Vampires", "Mistress of Vampires"): The power to possess the traits of a Vampire Lord. Variation of Vampire Physiology. The user either is or can transform into a Vampire Lord, the most powerful form of vampire. Unlike lesser vampires, the vampire lord possesses inherent skill in dark magic and can command legions of undead minions/vampires. Also, vampire lords are known to have a certain resistance to sunlight for prolonged periods of time and have the fewest weaknesses; on top of that, even if they die, they are powerful enough to be reborn after a specific time period has passed. Furthermore, depending on the user, they may have a demonic nature, thus granting them access to the most unholy of powers.
- Dark Lord (also known as "Dark God/Lord/Master/Prince", "Evil/Dark Emperor/King/Lord/Overlord", "Lord/Master/Prince/King/Emperor of Darkness", "Lord/Master/Prince/King/Emperor of Evil", "Lord of Shadows"): The terrifying title of devilish individuals who seek goals such as domination or revenge. Opposite of True Hero. Dark Lords are powerful evil beings who viciously rule over lesser evil beings and desire to rule their respective existences and corrupt as well as destroy everything they touch. They possess malevolent abilities and often command fiendish minions. These individuals also love to seduce others to join their side and then use them for their own hellish purposes. Anyone can be a Dark Lord; some are human, many have demonic natures and certain holders of the title are actually manifestations of the Prince of Darkness himself.
- Evil Embodiment (also known as "Evil Incarnate/Personification", "Malice Embodiment, Incarnate/, or Personification", "Source of All Evil", "The Malicious"): The power to be the embodiment/essence of pure evil. Variation of Power Manifestation and Malefic Force Manipulation. Opposite to Good Embodiment. The user of this power is or can become the embodiment of evil and can manipulate everything evil, including having all evil powers and power over evil beings, places and events (the user literally become a force of nature). Examples include using weather to destroy towns, cursing people to induce horrifying effects, physically and psychologically torturing people, inducing sins, etc. The user can also do things like shapeshifting into a chaotic monster and do almost anything as long as it ensures death, destruction or pain on the victims. The user of this power is incredibly powerful because of the limitless capabilities and the fact that it is evil in almost every place. The user cannot be "killed" and can exist anywhere, but their existence is far stronger in some places than others as long as the place isn't overrun by a good embodiment user. By nature somebody must always possess this power as evil has existed since the beginning of time and without evil, there cannot be any good. Advanced users may also be able to possess people and other supernatural beings and give them some power. This is known to some as Demonic Empowerment. More advanced abilities include not only the ability to possess people but also to possess land, objects, and flora to manipulate the surroundings.
- Satanic Incarnation (also known as "Lord/Lady of Evil", "Prince/Princess of Darkness", "Satan/The Devil Incarnate", "Satanic Physiology", "Supreme Demon King", "Ultimate Evil Being"): The ability to be a manifestation of and/or have the traits of the Devil. Not to be confused with Transcendent Demon Physiology or Devil Soul. Opposite to Godly Incarnation. The user of this power either is or merely has the traits of the ultimate evil being known in Christianity as The Devil and/or Satan/Lucifer. Unlike Devil Soul, the user is allowed to truly become the embodiment of all evil and use his power as they see fit. This power can be achieved by either being possessed by Satan, having a blood-tie to him, fusing with his essence or just being the greatest force of evil in the user's existence. Ultimately, this power grants the user of the archetype of Satan: the ultimate evil being, so the user could be a mythological god and still have this power. Other times, users fall from grace and become evil rulers. The power functions as an archetype, so even if the user is not the actual Satan, he or she represents him in his or her existence (ie The White Witch) and therefore does not wield the full power of the archetype. There were many individuals who had made frequent comparisons between Klaus and Satan because Klaus was so sinister, malevolent and evil.
- Omnimalevolence (also known as "Absolute Malevolence/Evil", "Transcendent Malevolence/Evil", "Eternal Malevolence/Evil", "Malevolent Personification"): The power to be infinitely and absolutely evil. Opposite of Omnibenevolence. Ultimate form of Evil Embodiment. Users of this power are devoid of any and all benevolent traits, thus making them the true evil incarnate and the source of all negative aspects of existence. Like its counterpart, this power has two versions: 1.) Inherent Omnimalevolence: to perceive and adapt perfectly to all evil concepts, 2.) Total Omnimalevolence: to be absolutely evil and surpass all forms of benevolence. The user is capable of being universally evil, but he or she can also deceive others into thinking they are actually good. Users can also spread their evil on cosmic and apocalyptic scales, simply by their presence or the power of their malicious will; they can corrupt anyone they desire, destroy virtually anything and cause terrible events to take place. In short, the user is the undisputed source of ALL EVIL whether it's natural, or in this case, supernatural. As with all omni-powers, there exists a Nigh-Omnimalevolence.
- Fear Embodiment (also known as "Fear Incarnate", "Fear Personification", "Horror Embodiment", "Paranoia Embodiment", "Terror Embodiment", "The Fearful"): The ability to become an embodiment of fear. Variation of Emotional Energy Manipulation, Fear Manipulation and Emotion Embodiment. Ultimate version of Nightmare Embodiment. Users can become a physical manifestation or personification of fear and gain power from the fear in others or oneself. Users can use fear as a power source to extend their life span or as a weapon, they can become immune to death unless certain conditions are met.
- Chaos Empowerment (also known as "Chaos Affinity", "Chaotic Force Empowerment/Affinity"): The power to be empowered by chaos and chaotic forces. A sub-power of Chaos Manipulation. Variation of Affinity. Opposite of Order Empowerment. Users become stronger, faster, more durable, etc. by/from chaos, possibly unlocking abilities related to the affinity and enhancing the existing powers. Some users may be able to draw sustenance from the chaos or even slow or stop aging.
- Absolute Immortality (also known as "Banned from Death/Dying", "Complete, Eternal, Meta, Perfect, Pure, Total, or True Immortality", "Eternal/Unkillable Physiology", "Unkillability"): The power to be eternal and indestructible. Absolute version of Immortality. The user possesses absolute immortality, is unable to die, age, get sick, or be permanently wounded, is absolutely self-sustained, and as the user's mind and soul are as immortal as their biological bodies, they are immune to mental/spiritual damage. Any injuries the user suffers immediately heal, even if the user's body is disintegrated or blown up or completely deleted, even if the user is completely destroyed to the sub-atomic level, they will still return to life. Alternately, some users are absolutely immune to all harm, and can never die from any natural causes. The user's existence and soul become completely free and independent of even the concept of reality, making them unbound to the subjects of life, death, and manipulations. Also, the power cannot be removed, rendered truly perfect and absolute. Klaus is an Old One and nothing can kill him, destroy him or weaken him. However, the only thing that can kill Klaus or any Old One like himself is the blood of a Guardian (such as Elena Gilbert) but since Guardian's are a rare species, Old Ones are still indestructible.
- Immortality (also known as "Death Immunity", "Deathless", "Endless/Eternal/Everlasting Life"): The power to never age and recover from almost any injury. Opposite to Mortality. Users possess an infinite lifespan and can shrug off virtually any kind of physical damage. Some users are the defensive type, simply preventing such damage from appearing (invulnerability/protection), while others are the regenerative type, surviving and quickly recovering from anything you throw at them.
- Conversion (also known as "Racial Conversion", "Species Conversion/Transformation", "Turning"): The power to transform people into different creatures. Opposite to Conversion Negation. User can permanently transform other beings into other kinds of creatures, typically the kind they are; for example, vampires transforming humans into other vampires through a bite.
- Compulsion: The supernatural ability to control and manipulate the body, mind, and soul of an animal or person.
- Weather Control: The supernatural ability allows influence meteorological energy patterns, creating rain, wind, hail, lightning, snow, sleet, fog and temperature changes.
- Elemental Manipulation: The supernatural ability to control and manipulate the elements of air, earth, fire, water, lightning, etc.
- Animal Control: The supernatural ability can handle all kinds of wild animals or domestic. Normally you can only control a species at a time.
- Healing: The supernatural ability to heal all infections and injuries at an accelerated speed.
- Senses: The supernatural ability to hear, see, smell, and taste beyond the human limit.
- Shapeshifting: The supernatural ability to alter and change the physical form of oneself.
- Speed: The supernatural ability to jump, move and run at superhuman velocity.
- Strength: The supernatural ability of abnormal strength.
- Illusion: It is capable of disrupting the reality of one or more things at once. The Illusion is limited since it uses a short time but because the neutralization of the enemy and does not usually give orders to the victims.
- Telepathy: The supernatural ability can communicate mentally with other vampires without physical contact and long distances.
- Immunity: The Old Ones can not be destroyed by sunlight, fire, wood, werewolf bite, decapitation, extraction of heart, etc. The only thing that could hurt them is the White Ash Wood, and the Principal Guardian's blood can kill an Old One.
- Old One Aura: A subtle, "luminous radiation" that surrounds an Old One that could alter the emotions and energy levels of himself and others. The Old One can generate aura within oneself. The aura is created from the power, longevity, strength and personality/emotions of the ancient vampire. The color varies according to each Old One, but in general are pure colors, but with the bloody red color, giving the feeling of evil and fear of anyone approaching the ancient vampire.
- Resurrection: The supernatural ability to return from the dead. In order to resurrect an Old One, they need the blood of the descendants. In case the body was destroyed, it is possible that the essence of the Old One occupies one of his/her descendant's body.
- Uninvited: A vampire cannot enter a home inside which they have not been invited.
- Running Water: A vampire can not cross running water but can tunnel beneath it.
- Veil Matter (Ghosts and Spirits): A vampire can not hurt and defeat a ghost. But ghosts can manifest and send a vampire to a place where they can not do more damage.
- White Oak Tree: It is known that the ashes of the white oak tree can hurt an old one. It's presumed an actual stake made of a white oak tree can hurt an old one.
- Principal Guardian's Blood: The pureblood vampires can only be completely destroyed if they ingest the blood of a Principal Guard
