Andreiko Igorobravitch

Andreiko Nero Igorobravitch (1960- 2 May 1998) was a Pure-blooded Death Eater from Romania. His parents were loyal members of the Alliance of Gellert Grindlewald who were imprisoned and died in Grindlewald's service respectively. He attended Dumstrung Institute School in his youth, but was expelled in his last year for using the Cruciatus Curse on a fellow students named Jöns Borresen and Jillie Kristiansen. He later became wanted in the Wizarding Community for attempting to poison the Romanian Minister of Magic. Eventually, Andreiko, fulled by his passion for the dark arts, his hatred of muggles and his desire for vengeance against the Aurors of the Wizarding World for his parents fates caused him to join Lord Voldemort's Death Eaters. Andreiko, like many Death Eaters, participated in the First Wizarding War and was responsible for some of the worst muggle killings, as well as the deaths of several Aurors. He was eventually captured by Alastor Moody, Remus Lupin and Markko Teräsinen while attempting to kill the son of Jillie Kristiansen and Alex John and was sentenced to Azkaban for life without a trail for the pain and suffering he had caused by Bartemius Crouch Snr, which even Sirius Black, who had a deep dislike of the Head of the Department of International Magical Cooperation for how he had subjected him to the same treatment approved. Andreiko later escaped with a group of Death Eaters and fought in several battles of the Second Wizarding War, including the Battle of the Department of Mysteries, the Battle of the Astronomy Tower, the Battle of the Seven Potters and the Battle of Hogwarts, where he met his death.

Early Childhood

 * "This World is just...too small""
 * ―Andreiko`s thoughts on his life before or during learning about his true potential of his magic skills

Andreiko was born to Vladeck Igorobravitch and Ajmirsa Trandafiruscat and was raised to believe that his parents' families were practically royal and that Muggles were the scum of the earth. His father, Vladeck, was a Siberian wizard (and former dark wizard who was a Follower for Grindelwald) who was sent to Azkaban for an attempt to find and free Gellert Grindelwald from Nurmengard when Andreiko was 5. Andreiko`s Mother, Ajmirsa, was a Romanian witch who also believed that wizards are somehow morally superior to Muggles. When Andreiko was sixteen, his mother was sentenced to a Dementor's kiss for mercilessly killing aurors and their families such as spouses and children (probably to free Vladeck and continue with the mission to free Grindelwald). Andreiko only saw his father once after his arrest and saw his mother for the last time a mouth before her sentence was carried out. Soon afterwards, Ajmirsa's body died from lack of food, having lost the will to eat and live with her soul. Both his parents were the last members of their family to bare the Igorobravitch and Trandafiruscat names (Ajmirsa having continued to use her maternal name after her marriage) and left their families' vast wealths to Andreiko. The loss of his parents probably made Andreiko bitter, more sadistic and selfish than he already was, and it would probably push him into becoming a Death Eater (possibly one of the most feared ones as well). After his mother's imprisonment, Andreiko was raised by his mother's sister, Mihaela Caecilius (nee Trandafiruscat) and her husband, Ionuţ Caecilius, who treated him like their own son and educated him in the Dark Arts, having been silent supporters of Gellert Grindelwald themselves. At some point in his life Andreiko was able to channel his first magic and thus learned about his would be true potential. While he was learning about magic he got to learn that the Wizarding World is nothing more but a mere counterpart of each country, continent and land on earth and because of this Andreiko grew envious of the Muggles by the fact that Muggles in fact owned more land.

School Life
Andreiko attended Durmstrang Institute when he came to the age of eleven, he was very skilled and talented at Dark Arts which caused him to become more and more reckless with such Powers, even gaining a lust for might especially after hearing about the tales of the Deathly Hallows and The Centre of All Magic. Before beginning his school years, Andreiko bought a 11¼ long Spruce wood with a Dragon Heartstring for a core from Mykew Gregorovitch.

However, during Andreiko`s sixth before his last year at Durmstrang he got expelled due to an torture attempt and killing attempt on a the danish student Jöns and at a Norwegian Durmstrang girl Jillie. The most likely reasons why he tried to kill Jillie and Jöns was because that Jillie was in love with a muggle-born student from Hogwarts (aka Alex John) and sending love letters to him or due to his anger of what has happened both to his own Mother and Father, who' deaths left him allow in the world. Andreiko decided to attack her but Jöns the danish student decided to defend Jillie. Angered, Andreiko went so far that he used a successful Cruciatus Curse at Jöns. However the Romanian student Gladok and his finish friend Pekka Teräsinen together with the Bulgarian first year student Plamuk Ansem and the fifth year student Aleksi Kuumatar saw this and told the headmaster. The Headmaster of Durmstrang caught Andreiko, ended the curse on Jillie and Jöns and helped nurse them back to health before expelled Andreiko.

Life After School
Andreiko originally would have been invited to an hearing after the events in Durmstrang, however Andreiko refused to accept the invitation and decided to poison the Romanian Minister of Magic by putting scorpion venom in the Minister`s tea, luckily (for the Romanian Ministry at least) the Minister survived. Andreiko Igorobravitch later was approached by Lord Voldemort due to his passion for power and the dark arts and his hatred for the Aurors (and possibly viewing Muggles as the source of all atrocities in the World), offering him rewards (probably such as getting some of the Power of The Centre of All Magic) and revenge on the Aurors for the suffering they had caused him. Andreiko's aunt and uncle were both supporters of the Death Eaters, but never joined them themselves and kept their loyalty hidden. Andreiko participated in many Deah Eater schemes and was even promoted to be "Lieutenant" of the "Dark Arted" Death Eaters (as Belllatrix was the general of the Dark Arted Death Eaters)

Captured and Imprisonment
During the dawn of the year 1981, Andreiko Heard that Jillie and Alex John had a baby, Ulf-Harald John, and as such he decided to take revenge on the Young couple (and possibly to show the might of the Death Eaters) by attacking the young child during one night. However things did not go as planned as he was captured by Alastor Moody, Remus and by Markko Teräsinen (the cousin of Pekka). There had been no doubt about the atrocities committed and so Andreiko was put away for life. Andreiko then spent the next 14 years in his maximum security cell surrounded by Dementors, enduring his worst memories.

Escape
Andreiko was intended to spend the rest of his life in Azkaban but he escaped in 1996 together with Bellatrix, Rodolphus and Rabastan Lestrange, Antonin Dolohov, Augustus Rookwood, Tav Travers, Dirk Gibbon, Ambarage Mulciber, Mr and Mrs Snyde, Mr and Mrs Lee, Cassius Grey, Jonathan Crane and many other Death Eaters, after a mass Dementor revolt and re-joined his newly-returned master. Andreiko had several special magic abilities such as his ability to "tame" Dementors which made him very useful to recreating the horrors during the Second Wizarding War. These Death Eaters were considered to be some of the most dangerous and highly guarded convicts due to their crimes being brutal and legendary. As a result, Andreiko and his allies became wanted witches and wizards, living in hiding to avoid being captured by the Ministry.

Battle Of The Department of Mysteries
Andreiko accompanied Lucius Malfoy and the other Death Eaters on their assigned mission to the Department of Mysteries. When he, together with other Death Eaters surrounded the eight D.A. members, he sneeringly claimed how foolish Potter was for believing the illusion, telling him his guardian's really should have taught him the different between dreams and reality and revealed to Harry that he saw only what "the master" wanted him to see as he tears of his mask to reveal his face. Though he was enraged by Harry saying the Dark Lord's name, hissing in fury at Harry word or Voldemort being a half-blood and was only seconds from firing, he was stopped by Lucius Malfoy, who suggested to him to give Potter a moment to decide. Despite this, he was very condescending when dealing with the eight D.A. members and tried, unsuccessfully, to retrieve the prophecy from Harry Potter via a Summoning Charm, as his efforts were stopped by Harry's quick use of his own Shield Charm. As Harry and his freinds fled into the deeper areas, Lucius ordered Andreiko to remain in the hall in order to block their way, should they bypass the exits and return to the center. After the group entered the Death Chamber, Andreiko was summoned to battle and joined his fellow Death Eaters in erupting into the chamber via Umbra Flight and held Ulf at the wandpoint, pushing his wand hard enough to bite into Ulf's skin as Lucius threatened to have his Death Eaters kill Harry's friends, should he refuse to hand the Prophecy over to them. At the sound of this threat, Andreiko brightens up considerable, telling the Boy-Who-Lived that he and his fellows knew many ways to bring a long and painful death, gleefully twisting his wand deeper into Ulf's skin. Just then, Order of the Phoenix members Sirius Black, Nymphadora Tonks, Pekka Teräsinen, Remus Lupin, Kingsley Shacklebolt and Alastor Moody burst into the room and a huge fight instantly ensued, during which, Andreiko duels Remus Lupin before being forced into the air by the werewolf's superior duelling skills. As battle continues, Andreiko flies around the chamber, firing curses and hexes at the young heroes before meeting in combat with Ulf-Harald. Unfortunately, the young D.A. boy, skilled as he was, was still junior in front of Andreiko and is knocked into the side of the lowest tier of seats as Andreiko advances forwards, preparing to finish the defenceless boy of with a Killing Curse, only to be blasted away by Ginny and Luna. Giving a furious, snake-like hiss, Andreiko melts into smoke. Just then, Albus Dumbledore arrived through the same door the Order members had come through, his wand aloft and utter fury in every line of his face and charged right into the middle of the fray, as the first Death Eaters suddenly realised he was there. There was a roar of shock, and the Death Eaters instantly attempted to flee out of utter fear of duelling him. One Death Eater fled up the side of the chamber in such terror, but Dumbledore quickly intercepted him with a simple blocking Spell. Andreiko attempts to escape via the open door, but is caught by a strong Stunning Spell from Dumbledore, bringing him crashing down. Andreiko and his Death Eater fellows were captured (with the exception of Bellatrix), but, unlike the rest, Andreiko was kept in the Ministry for questioning. However, as the Aurors were escorting him to Azkaban, they are attacked by a squadron the Death Eaters, who had now come out into the open, who killed the entire guard and allowed Andreiko to escape.

Plot to Kill Albus Dumbledore
Andreiko participated to kill Albus Dumbledore, he attended several meetings about the subject. In one meeting Andreiko suggested to use the cursed necklace to kill Dumbledore. Andreiko participated in sending deadly objects to Hogwarts via the Vanishing Cabinet.

Death of Albus Dumbledore and the Battle of the Astronomy Tower

 * "When the time is right, we will make sure that all hope turned against you Potter, when the end of your precious headmaster is gone,forgotten,dead,destroyed all hope for your future and the future of your pathetic ignorant friends is lost in the darkest parts of oblivion, when we get to destroy your beloved headmaster then we will see how long you want to live a regular life and play the pacifist""
 * ―Andreiko`s message to Harry via a letter called "from your feared darknesses" a few months earlier Before Dumbledore`s death

Andreiko joined in with Bellatrix, Fenrir, Rolf-Rufus Darkwood, Dirk Gibbon, Corban Yaxley, Thorfinn Rowle and the Carrows via the Vanishing Cabinett to join Draco on his "final task" to truly become a Death Eater. Up in the Astronomy Tower Andreiko taunted Dumbledore how a fool he was for letting himself get disarmed by a young boy such as Draco, however his honouring of Draco turned into anger and frustration when Draco refused to use the Killing Curse and even decided to push Draco to cast the Killing Curse by using the Cruciatus Curse on the poor emotionally broken boy only to get stopped by Snape, who Andreiko respectfully steps away from as he enters. After the Death of Dumbledore, Andreiko mercilessly humiliated Harry on how everything has been turned against Harry and how powerless Harry is to change anything that had recently happened and did duel with Harry and Ginny a bit before being ordered by Snape to retreat away from Hogwarts in order to escape possible Auror ambush.

Despite complying to his leader's command, Andreiko still cannot stand escaping without giving Hogwarts "something to remember them by", striding along the Gryffindor House Table in celebration as he kicks asides cutlery and dishes aside. Finally, in insane celebratory outburst of the death of Albus Dumbledore, Andreiko casts the Reductor Curse at the enormous main windows, shattering the hall's windows and extinguished the floating candles in a rush of wind. However, alerted by the sound of running feet, Andreiko abandons his celebration, blasting the doors leading out of the castle and stunning John Dawlish, sending him flying down a flight of stairs.

As the Death Eaters escape across the ground, Andreiko tauntingly greets Hagrid as they approach the half-giant's hut and greets attempted to curse him, but his curses had no effect on Hagrid because of his Half-giant blood. However, just as Hagrid is about to attempt to fire a spell at the Death Eater, using his umbrella-wand,  Thorfinn Rowle sets the hut aflame, to Andreiko's whoops of savage, sadistic joy as he leaps up and down in delight, pelting Hagrid with insults as the gamekeeper turns back to rescue his dog Fang, who was inside. Just then, a spell shoots passed Andreiko, forcing him to leap aside with an undignified yelp. Turning with a snarl, Andreiko catches sight of Harry Potter, and, laughing maniacally, fires a Cruciatus Curse towards the boy, which Harry only just misses, only to be stopped by Severus Snape, who at the time was operating in his capacity as a double-agent in open support of Voldemort, who orders Andreiko to leave Harry Potter, who's death was to be only at their master's hands, which Andreiko obeys, running across grounds and Disapparating away with Alecto and Amycus Carrow, Thorfinn Rowle, Draco, Bellatrix and Snape.

Meeting at Malfoy Manor
Andreiko attended the meeting at Malfoy Manor with his fellow Death Eaters, sitting between Serena Tyranicus and Acrustus Undewood. He was impressed when Yaxley announced that he had placed Pius Thicknesse, the head of the Department of Magical Law Enforcement, under the Imperius Curse. He along with other Death Eaters, laughed when Voldemort insulted Bellatrix Lestrange and the Malfoy family, regarding Nymphadora Tonks marrying werewolf Remus Lupin and later on when a Squatrand Goyle remarks that, for once, the Order had been correct when Snape informs Voldemort of the Order's belief that the Death Eaters had infiltrated the Ministry and was highly impressed by Corban Yaxley's announcement that he had placed Head of the Department of Magical Law Enforcement, Pius Thicknesse under the Imperius Curse. The Dark Lord then questions Andreiko if their preparations for an attack on the Ministry were complete, which Andreiko replies in the positive, telling him that followers of the Death Eaters kept him, Bellatrix and the other Death Eater commanders well informed and informs him that their was yet no news of Order members near Number 4, Privet Drive, which he refers to as "the filthy Muggle home of the Potter boy".

Battle of Seven Potters
Andreiko participated in the Battle Over Little Whinging, during which he pursues Remus Lupin and George Weasley (the latter whom was disguised as Harry), alongside Severus Snape. As he prepares to fire the Fiendlightning Curse at them however, Severus Snape attempts to hit him with a Sectumsempra curse, attempting to slice of his hand. However, just as he fires, Andreiko raises him hand suddenly to deliver his curse, causing Snape's spell to slice of George's ear. This distracts Andreiko, however, causing him to stop mid-spell and causing the incomplete spell to fade to nothing.

Soon afterwards, the pursuers are joined by Voldemort, who quickly realized the Harry they are pursuing is not the real Boy-Who-Lived and, upon summoning four more Death Eaters, orders Andreiko to search Privet Drive for the Dursleys, who he hoped to use against Harry, Andreiko complies and, alongside Severus Snape, Rufus Darkwood, Serena Tyranicus, Thorfinn Rowle, the Caleb cousins: Sinsra, Elinora, Cruz and Vestia Kresif and Vladmir Menshikov, twist around and swoop towards Privet Drive. As the slip to the ground, Andreiko, wand already raised, fires the Bombarda Maxima charm at the door, blasting it off its hinges, which Snape reprimands, stating that unless Andreiko wanted the entire street on them, they should cast Silencing Charms, with Andreiko complies to. As they enter, Andreiko dispatches all the Death Eaters apart from Severus to search the house while he and Severus perused the main room. Catching a glimpse of Dudley, Andreiko sneering comments how "this ones ugly". As he walks down the hall, he absently crushes Dudley's knight set and destroys the door the cupboard underneath the stairs. However, his calm demeanor falls as the Death Eater report failure and he realizes that the Dursleys had been hidden by the Order, causing him to lash out, shattering and breaking nearly every window and door in the house, leaving it broken and crushed. As he and other Death Eaters exit, Andreiko sends the house into flames with a Ghoulfire Curse before he and his companions all send Slicing Curses and the house's support timbers, causing it to collapse in on itself.

Skirmish at Malfoy Manor
Andreiko accompanies Bellatrix on her trip to Malfoy Manor. As they walk up the gravel path to the Manor, Andreiko is startled by a sudden wrestling in the bushes, drawn his wand, only to relax as an Albino Peacock strutted onto the lawn, sneering that Lucius always indulged himself uselessly, which Bellatrix agrees to.

Bellatrix and Andreiko later come across Lucius, Draco and Narcissa attempting to distinguish if the three Fenrir Greyback and his Snatchers had captured. As Bellatrix and Lucius argue about who should have the honour of summoning the master, Andreiko silently draws his wand in case Lucius attempted anything. When Bellatrix spotted Godric Gryffindor's Sword amongst the trio's captured possessions, however, she at once flew into a panic because the sword (as far as she knew) was hidden in her vault and ordered the Snatcher holding the sword to hand it over to her and stunned the man when he refused. The other Snatchers turned on her at once, but even though it was four on two, they were no match for her and Andreiko and they quickly stunned three of them and Andreiko forced Greyback to his knees, demanding to know where he had found the sword. He then informed her that the sword had been found in the Trio's tent. She then took charge of the situation by resorting to torturing Hermione into revealing how the sword was in the Trio's possession and demanded that the rest of the prisoners be taken into the cellar temporarily, while ordering Andreiko to place the Stunned Snatchers in the courtyard to be disposed of by her personally at a later time.

After fulfilling these orders, Andreiko returns and he and Bellatrix torture Hermione. Andreiko shoots a curious glance at Bellatrix, confused at the Dark witch's fear of Hermione being in her vault, but otherwise remains silent as Bellatrix interrogates Hermione, slashes across Griphook's face with a spell and kicks the goblin aside. The torture is then interrupted by Ron and Harry, Ron disarming Bellatrix, using Pettigrew's wand and Harry stunned Lucius and Andreiko, sending him stumbling. However he recovers and, alongside Bellatrix, threatens Hermione, pointing his wand at Hermione's heart as Bellatrix demanded that the prisoners drop their wands, and smiles in delight as Bellatrix pressed her Dark Mark, calling Voldemort.

Just then, however, a crystal chandelier loosened by Dobby comes crashing down, the vibrations of which causes an enormous brass gong to fly outwards into Andreiko's head, throwing him into a rosewood desk, which he smashes into, knocking him out and causing a large vase to fall over and cover his head, incapacitating him for the rest of the battle. Andreiko, Bellatrix and the Malfoys were severely punished by Voldemort for allowing Harry to escape, but Voldemort was much more lenient in his punishment with Bellatrix and Andreiko because of their past services.

Battle Of Hogwarts And Death
Andreiko was summoned to battle by his master with the rest of Voldemort's army and participated in the following battle, during which he killed Plamuk, Aleksi and Gladok. At one point during the battle he killed Pekka's father and uncle. He retreated into the glades of the Forbidden Forest at Voldemort's summonings and where he was seen holding down Hagrid with several others. He later watched witnessed Voldemort attempting to kill Harry Potter with a Killing Curse and shot sparks of red and green into the sky in celebration and aided Bellatrix, Thorfinn Rowle and Antonin Dolohov in firing a enormous Dark Mark into the sky.

As the Battle of the Great Hall commenced, several duels outside the hall continued as friends and foes who had escaping the Entrance Hall, continuing to fight in the courtyards, walls and towers in and surrounding the Great Hall, and though the Death Eaters were fighting with the most gruesome of spells, they were no match for the combined efforts of the school's forces and the newly-replenished forces of the order. Within the divination area of the Clock Tower Courtyard Pekka Teräsinen and his cousin Markko dueled both their fathers' killer: the criminally insane death eater, Andreiko Igorobravitch. Andreiko, as usual, dueled very foully as he casted two Cruciatus Curses right at Pekka's face and chest, throwing him, jerking, into the wall violently, before beginning to inflicting Pekka with more torment from the Fiendlightning curse while, at the same time, violently wounding and injured Markko (both with Curses, Hexes or even non-magical physical harm) until he was weak enough for him to try to cast the Killing Curse at Markko, think in his arrogance that he was defenseless and had no chance of survival but to his surprise and anger Markko countered it with his last strength, defending him and his cousin with a Disarming Charm. Thus a beam of a Reverse Spell (Prior Incantato) combined with a frantic Stunning Spell (Stupefy) and (surprisingly) two Patronus Charms (Expecto Patronum) which took the forms of a Antipodean Opaleye dragon (Pekka) and a Sea Serpent (Markko) shone across the paved floor, causing Markko's father, Pekka's father and Andreiko's other battle of Hogwart's victims to appear, much to Igorobravitch's terror. Because of this, Andreiko decided to use the wandless Summoning Charm with his hand to get the closest wand from a nearby recently fallen Death Eater fellow that had been killed when the death eaters stormed the Great Hall in order to use another Cruciatus curse at his foe, Markko in order to weaken him and destroy the apparitions of his ruthless murders, discarding the 11" length, Spruce wood wand with shed Dragon heartstring for a core that had served him loyalty and faithful for his entire life without a second thought in replacement for a wand he hadn't earnt honorably only for that wand to be destroyed by Pekka who had risen up and intended to help his cousin by giving "some of Andreiko`s own medicine". Andreiko got hit by an stray centaur's arrow in his left arm's lower clavicle of his shoulder and later by the Vermillous Charm in his chest by Pekka (thus weakening Andreiko the same way as he has injured Pekka and Markko before) who then decided to combine his wand with his cousin's wand to make the strengthen the effects of the Disarming Charm thus the "orb" of the beams incantatem headed towards Andreiko who attempted to shoot a Killing Curse only for his curse to meet the two cousin's charm and to be smashed through and disarm Andreiko, throwing the wand into the air while still firing its murderous curse, now heading straight for its caster, who was both blasted by both his own Killing Curse and the Disarming Charm and hitting the ground,already stone dead. Andreiko died in complete disgrace and his death ended the Igorobravitch and Trandafiruscat family lines.

Personality And Traits
Andreiko was cunning and filled with lust for success and power and was incredibly foul towards his enemies, viewing himself to be above everyone else. Andreiko was also incredibly sadistic and showed no remorse for his own actions. Because of these types of traits it is possible that Andreiko was a sociopath or at least shared traits of one.

When failing missions or if the Death Eaters fail Andreiko would become extremely insidious and merciless, One example would be after The Battle of The Seven Potters, Caleb Kresif and his cousins and sister was going to look if the true Harry was still in Privet Drive 4, and when he was not Andreiko lost his temper and smashed multiple windows, blasted a several doors and destroyed Dudley's knight toys. It should also be noted that his fellow Death Eaters feared him as he was a madman bent on domination, even Lucius Malfoy admitted the brutality of Andreiko and even started crying in fear several times he saw Andreiko commit his gruesome atrocities.

Andreiko had a strong hatred for Aurors due to his father and mother being sentenced by them. The reason why Andreiko hated muggles was mostly because of jealousy, he hated the fact that wizards are only able to rule the magical counterparts of each country and not both counterparts while the muggles had more landscape and by that he claims his actions are justified as its only to bring justice for his dead parents and punish the muggles for their "barbarism".

When Andreiko was young and was a student at Durmstrang he was very arrogant, boastfull, cunning and mean spirited and always was obsessed with the dark arts, which was eventually to evil for even Durmstrang.

Magical abilities and Skills
Andreiko was a highly powerful and dangerous Death Eater. His immense magical skills allowed him to go up against and defeat many powerful wizards and witches, including many Aurors and Order of the Phoenix members.
 * Dark Arts: Being a sadistic Death Eater, Andreiko was highly proficient and talented in dark magic and the casting of dark charms, making him a formidable Dark Wizard. Andreiko could cast the Unforgivable Curses (which require ability and genuine malice to perform)
 * Umbra Flight/Shadow Flight: Like all death eaters, Andreiko had the ability to fly without the aid of a broom.
 * Duelling: Antonin Dolohov was an extremely skilful duellist, highly proficient in martial magic and was one of the most dangerous and feared Death Eaters. However, Andreiko died in a duel, due to his own arrogance.
 * Apparition: Andreiko possessed the ability to teleport with Magic and could silently apparate, which often aided him in battle.
 * Spell Creation: Andreiko was known creating a few deadly curses like the Phantom Pain curse.
 * Transfiguration: Andreiko was able to conjure ropes from his wand, which implied he was highly proficient in this notably complicated branch of magic, as conjuration is an advanced form of transfiguration.
 * Charms: Andreiko appeared to be skilled with charms, as he was able to cast the Summoning Charm in a failed attempt to get the prophecy from Harry Potter in 1996
 * Dementor Taming: He had the ability to take control over dementors, which he used to aid his master in convincing the Dementors over to the dark side.

Lord Voldemort
Andreiko was one of Voldemort`s advanced warriors.Voldemort gave Andreiko rewards and also promised him revenge against the aurors,he showed loyality to Voldemort however despite this he only showed loyalty to Voldemort because he saw Voldemort as someone who would give him power and rise up

Bellatrix Lestrange
Andreiko showed huge respect for death eaters like Bellatrix and her husband. Despite being much younger than Bellatrix, Andreiko stated that if Bellatrix was not married, he would have taken Bellatrix as his bride and partner in life.

Harry Potter
Even if he never knew Harry as Lucius did, he did know some stuff about him, he viewed Harry as a "foolish kid who thinks its so easy to be an "hero"

Ulf-Harald John
Andreiko tried to kill Ulf when he was just a kid since he was stopped by Remus ,Markko and Moody and taken to Azkaban.Many years later Andreiko managed to escape the prison together with Bellatrix, Dolohov and some others and met Ulf in the ministry of magic.Andreiko Hated Ulf as he viewed him as the reason why he "rotted" in Azkaban for so many years.They both battled many times during the battle of the department of the ministry and eventually in the Battle Of Hogwarts.

Severus Snape
Andreiko, like so many other Death Eaters, regarded Severus Snape in a mixture of awe, respect and fear.

Ron Weasley
Andreiko considered Ron to be a weakling undeserving of magical blood and made fun of him for "cracking up" when Bellatrix harmed Hermione at Malfoy Manor stating that it is nice to know Weasley crack easily.

Hermione Granger

 * "I have a funny assumption about you, me or lady Lestrange here could use cruciatus curse on you, tear and smash your limbs into pieces all day and you would still find a way to try "bite back" if thats a description i may use"
 * ―Andreiko`s dark words to Hermione in Malfoy Manor

At Malfoy Manor Igorobravitch lectured Hermione of her being guilty of siding with The Dark Lord`s sworn enemy, having the blood of "filthy muggle barbarians" and deserves "a rebel`s torment and death" and together with Bellatrix decided to make an example of her for her "stupidity" when they started to interrogate the Girl.
