Hagrid

Professor Rubeus Hagrid is an English half-giant wizard, son of Mr Hagrid and the giantess Fridwulfa, and elder half-brother of the giant Grawp.

Hagrid attended Hogwarts School of Witchcraft and Wizardry in 73 BBE and was sorted into Gryffindor house. In Hagrid's third year, he was framed by Tom Riddle for the crime of opening the Chamber of Secrets and using his pet Acromantula to attack several Muggle-born students and eventually killing one of them. Though Hagrid's wand was snapped and he was expelled, he was trained as gamekeeper of Hogwarts and allowed to live on the school grounds at the request of Albus Dumbledore.

Guards of the Unknown
While Squiggly, Bill Weasley and the others studied at Hogwarts Hagrid always invited them to his house for rock cake or tea. Squiggly, Charlie and Orion often visited Hagrid and Hagrid became very loving and protective over them. Hagrid can be quite a powerful ally and often helped the Guards of the Unknown on their adventures.

Hogwarts
Early in their first year BBE school year, Hagrid rescued a Squiggly from Devil's Snare, over time Squiggly seemed to have grown on Hagrid during her time at Hogwarts and gained his trust.

Fang
In their second year, Hagrid needed ingredients for a Fire-Breathing potion and asked Squiggly to help him. He didn't tell her what for and once Squiggly and her friends gathered the ingredients Hagrid sent them to Snape to make the potion when the potion was done Squiggly asked Hagrid what all of it was for and Hagrid revealed he needed the potion to free his new puppy from the same Devil's Snare he once saved Squiggly from. Hagrid even let Squiggly name the puppy and she named it Fang.

Magical abilities and skills

 * Magical Mastery: Despite having never graduated from Hogwarts and therefore not being fully trained in the magical arts as well as probably not often practicing magic as he wasn't allowed to do so technically in his own admission as he had been expelled from Hogwarts and his wand was apparently destroyed some years earlier, Hagrid's magical aptitude was clearly astonishing as he proved to be quite accomplished and skilled in magic enough that he was able to successfully conjure moderate levels of powerful magic, performing successfully the majority of his spells using non-verbal magic via his umbrella and as his wand was apparently destroyed, he may also have been capable of wandless magic as well, both of which only extremely powerful wizards and witches proved capable of using effectively. However, Hagrid's magic was never flawless as he was the only member of the Order of the Phoenix who could not cast the extremely powerful and difficult Patronus Charm and failed to completely transfigure Dudley Dursley into a pig, although he admitted that since Dudley was already so close to being a pig with his overweight physique and eating ways, he did not need to transfigure him completely, suggesting that Hagrid may have been able to do it but just chose not to further humiliate Dudley, and repair Sirius Black's motorbike which had been heavily damaged during the Battle of the Seven Potters, though it must be noted that he was also struggling to control the motorbike and therefore he may just have been unable to exert enough magic to do so.
 * Transfiguration: Hagrid was at least moderately proficient in Transfiguration, as shown in the Hut-on-the-Rock when he pulled off a partially successful transfiguration when he put a pig's tail Dudley Dursley in a failed attempt to transfigure him into said animal. He could also perform conjuration; in 1991 he used the Fire-Making Spell, while in the Hut-on-the-Rock and in 1997 the Water-Making Spell, to put out a fire in his hut during the Battle of the Astronomy Tower. This is fairly impressive, as Transfiguration is considered one of the most difficult branches of magic, and even experienced wizards struggle with it.
 * Charms: Hagrid was also accomplished with Charms as he could cast a spell of his own that can enchant a boat to move on its own to a destination, which he used to transport him and Harry back to the mainland from the Hut-on-the-Rock and used it on the Hogwarts boats to transport the first years across the Black Lake. Hagrid was skilled in the Engorgement Charm as he used it to enlarge his pumpkins to a giant size, his success impressing Hermione and Fred and George. Although he admitted to not having perfected it, he was competent enough in the Stamina Charm to successfully instruct members of the Statute of Secrecy Task Force who pursued a profession as a Magizoologist on how to cast them.
 * Non-verbal magic: Hagrid was quite skilled at using non-verbal magic, as shown when he both lit a fire non-verbally and transfigured a pig's tail on Dudley. These spells show that, even though Hagrid never graduated from Hogwarts, he had a powerful command of magic, as non-verbal magic was difficult to use (Hogwarts does not teach non-verbal magic until students are in their sixth year).
 * Care of Magical Creatures: Hagrid was also extremely knowledgeable about magical creatures and was highly skilled in looking after, interacting with, and gaining their trust, including dangerous creatures which likely contributed from his experiences in the Forbidden Forest and with his pets. Hagrid's skill and knowledge in handling creatures allowed him to be the Care of Magical Creatures professor even though he was not a fully qualified wizard. Despite his skill and knowledge, many students considered Professor Grubbly-Plank a more qualified teacher for the subject as Hagrid preferred teaching dangerous creatures and could lose his confidence if students tried to disrupt his classes or if he believed they did not like his classes. However, when Hagrid stopped dealing with dangerous creatures too much and began to become more experienced in teaching, his skills proved to be impressive enough to make him a reasonable teacher, as he proved to be able to improve all of the students excluding Slytherin view on him that they all expressed shock that Dolores Umbridge would sack him, although many of them did not choose to continue the subject for N.E.W.Ts due to their past experiences with the dangerous creatures he taught. The dangerous and unpredictable creatures which Hagrid taught included hippogriffs, Blast-Ended Skrewts, and thestrals. Although he believed that tame and less harmful magical creatures did not pose many challenges, Hagrid nevertheless possessed a remarkable amount of knowledge on them as well as monstrous creatures, enough that he was able to effectively continue Grubbly-Plank's lessons on unicorns and he also taught nifflers and flobberworms. Some of the creatures Hagrid looked after included a three headed dog named Fluffy, his pet boarhound Fang, a baby dragon named Norbert, an Acromantula named Aragog, a hippogriff named Buckbeak and his half-brother Grawp, who was a giant. While his teaching methods were questionable, his knowledge helped Harry and his friends on numerous occasions, such as when they got past Fluffy while protecting the Philosopher's Stone, helped Sirius Black escape on Buckbeak, faced a Blast-Ended Skrewt during the Triwizard Tournament, and went to the Ministry of Magic using Thestrals. It should also be noted that his knowledge was such that he was initially the only person apart from Dumbledore who knew how to subdue Fluffy through music as even Severus Snape was unable to get past Fluffy without getting injured, and Quirinus Quirrell, under Voldemort's influence, had to gather the secret from a drunken Hagrid on how to get past Fluffy (which Harry, Ron, and Hermione later learned) especially considering Voldemort and Snape were both already highly powerful and intelligent wizards even in their youths while Quirrell had experience with handling dangerous animals like trolls. Hagrid was skilled enough to gradually earn the respect and loyalty of Grawp, despite the protests of Harry, Ron, Hermione, and Firenze, along with Grawp's violent nature. Hagrid's knowledge in dealing with giants and other dangerous magical creatures also made Dumbledore order Hagrid to go and attempt to recruit the giants to fight against Voldemort, which he would have succeeded if not for the Death Eaters' interference and Golgomath's usurpation of the current Gurg, Karkus. Due to his friendship with Aragog, Hagrid was the only person who was able to visit the Acromantula tribe in the Forbidden Forest without being harmed, although this was lost after Aragog's death. Up until he rescued Firenze from the Forbidden Forest Centaur colony, Hagrid was among the very few that they respected and trusted, as he was able to visit them and interact with them cordially and Torvus even noted that Hagrid held enough influence that if Squiggly was a friend of Hagrid, the Centaurs would consider trusting her as well and it was his advice that eventually allowed Squiggly to earn their respect. This talent also helped him as he was trusted with leading the Magizoologist faction of the Statute of Secrecy Task Force and had efficiently taught the recruits how to handle beasts safely. This can all indicate that Hagrid was a considerably talented person on the subject and this was clearly his strongest subject, possessing more knowledge than even wizards who were more powerful and intelligent, despite lacking the qualifications along with the teaching experience and understanding to fully engage his students.
 * Potions: Although not a well-known skill of his and his actual level as a potion maker is unknown, Hagrid displayed a remarkable amount of knowledge in the subject. When he asked Squiggly to brew the Fire-Breathing Potion in order to burn the Devil Snare holding Fang in the year 1985, he was able to thoroughly explain to her all the ingredients needed to brew the potion and was aware that mint had cooling properties that would allow her to consume it without harming herself.
 * Superhuman Strength: Due to his giant blood, Hagrid possessed great levels of superhuman strength, as shown when Vernon Dursley threatened Hagrid with a gun, and Hagrid responded by easily twisting his gun to a knot as if the gun was made of rubber. Hagrid's great strength was also shown when, during the Battle of Hogwarts, he threw Walden Macnair across the Great Hall, a space which can easily fit all the students and staff at Hogwarts. The great strength of Hagrid was also seen whenever he tried to gently pat someone on the back, an act which usually sent the recipient flying. His strength also helped, given the kind of creatures he tended to look after, such as Fluffy, a gigantic three-headed dog, a 10-foot long Blast-Ended Skrewt and Aragog, an Acromantula the size of a small elephant (though seeing as he was Hagrid's friend, he might not have been that bad to look after). Hagrid's strength also proved to be a big advantage when in battle and a powerful blow from Hagrid could badly injure and knock a person unconscious instantly as shown during his battle with some Aurors in 1996. It is also possible that Hagrid was capable of killing a person or animal with powerful blows from his great strength alone, although this was rarely shown as conflicts with enemies were rare for Hagrid. Given Hagrid's absurd ease in handling creatures as large as Acromantulas, three-headed dogs, and his half-brother, Grawp, it can be safe to assume that Hagrid is capable of lifting well over ten-thousand pounds and exerting far more force in combat. Hagrid was also able to control Madame Maxime's horses which were each described as being the size of an elephant and required forceful handling. Hagrid's own massive size would take extreme power just to be able to move, so for him to be able to move as effortlessly as he does, let alone exert his strength as he does must mean that his strength is enhanced by magical means as well as physical. In fact, his strength was such that he was described to have wrestled trolls in the Forbidden Forest as a boy. Hagrid also regularly hauls in the massive Hogwarts Christmas trees simultaneously by himself with no discernible strain, even though each one weighs at least several thousand pounds based on their described height and probable species. Based on this, the full extent of Hagrid's superhuman strength, while never seen explicitly in the series, most certainly makes him a force of nature in his own right.
 * Superhuman Endurance: Hagrid is also known for being able to take quite a beating. Due to his outdoorsy line of work, Hagrid is able to exert himself at the peak of his superhuman strength for hours at a time without any known limits to how long he can maintain his stamina. Given that he is capable of keeping up with tutoring and taming his full-giant half-brother, Grawp, and still keep up with his lessons as a Hogwarts Professor, his duties as gamekeeper, maintaining a social life, and his various hobbies of tending to and caring for injured and sick animals in the Forbidden Forest, all while nursing injuries from Grawp, Hagrid certainly has vast levels of superhuman stamina that no other character has matched in the series. Hagrid's bodily tissues are also extremely strong, enhanced due to his giant blood, allowing him to endure beatings from his half-brother that would absolutely kill any ordinary man, regardless of their physical conditioning, although he still experienced visible and rather nasty wounds in the form of bruising and various minor cuts and lacerations throughout his body. Hagrid is also capable of withstanding torture from the likes of Voldemort and his Death Eaters, as evidenced by his maintaining of full consciousness after being captured during the first half of The Battle of Hogwarts.
 * Magical Resistance: Hagrid was resistant to stunning spells because of his giant blood. This also gave Hagrid some protection against curses, including moderate levels of Dark Magic as even the Death Eaters attempts to curse him after Dumbledore's death failed, which gave him an advantage whenever he was involved in a battle.
 * Toxin Resistance: Due to Hagrid's work with various magical creatures, many of which are venomous and highly likely to carry disease, it can be assumed that Hagrid's magical resistance affords him a degree of foreign chemical resistance as well. This can also be assumed in part due to his enormous size in accordance with his giant heritage, as toxicity in the body is relative to one's size and the amount of a foreign substance circulating within. This can also be seen in his difficulty with becoming intoxicated, as it took Quirrell several hours to get Hagrid drunk enough to divulge the information of how to get past Fluffy in the first chamber in 1992. In fact, Hagrid's resistance to alcohol toxicity is so strong that he was able to down an entire bottle of brandy in a single swig without any notable effects on his behavior or cognitive functioning following the Battle of the Seven Potters in 1997. Such a feat would likely be impossible for anyone of entirely human heritage without the aid of magic.
 * Arbalist: Hagrid was also a skilled crossbowman, a crossbow being his primary means of defense.
 * Physical Combat Skills: Hagrid was highly proficient at fighting physically. This was displayed in 1996 when Hagrid was attacked by Dolores Umbridge, along with some Aurors, who attempted to sack and arrest him. Hagrid managed to physically defeat all the Aurors effortlessly, which enabled him to escape from Umbridge. It should be noted that his combat was such that even Umbridge's remaining Auror was hesitant to attack Hagrid. Before that, he also rescued Firenze from the other centaurs in the Forbidden Forest after they attempted to kill him for accepting a teaching post in Hogwarts and escaped from the entire Acromantula colony of the Forest to give Aragog a proper burial all without any injuries, which is another testament to Hagrid's combat skills especially as both centaurs and acromantulas were powerful creatures in their own right. Also, in 1998, during the Battle of Hogwarts, Hagrid easily physically defeated Walden Macnair by throwing him across the Great Hall and he survived the battle. As Hagrid rarely used magic, he normally relied on these skills, his great strength, magical and physical endurance and possibly his crossbowman skills to fight in a battle and presumably used his skills to participate in the First and Second Wizarding Wars when he was a member of the Order of the Phoenix. However, he did occasionally use his umbrella-concealed wand when battling, indicating that he was willing to use magic against his opponents alongside his physical battling abilities when the time was right.
 * Gamekeeping Skills: Hagrid began his training as a Hogwarts Gamekeeper in 1943 after his third-year expulsion, possibly under Gamekeeper Ogg; it is known he would have been Ogg's assistant during the 1960s. Hagrid most likely was an efficient and skilled Keeper of Keys and Grounds as there was no mentioned blunder, replacement or substitute (with the exception of Professor Grubbly-Plank on two occasions) throughout his time in this position, and was able to keep up this position alongside his teaching duties as the Care of Magical Creatures professor and his duties for the Order of the Phoenix. These duties included escorting first-year students to Hogwarts, looking after the school keys, preparing for the Hallowe'en and Christmas feasts by preparing the pumpkins and Christmas trees respectively, performing secret and special tasks for the other Hogwarts teachers, and tending to matters which would be difficult for ordinary people and wizards to do such as tending to matters in the Forbidden Forest and looking after the magical creatures around the Hogwarts grounds.
 * Cooking: Living alone in his cabin, Hagrid cooked for himself, though he would have meals in the Great Hall on occasion, such as the various school feasts. He apparently enjoyed his own food, though, being a half-giant, his tastes often clashed with those of his guests. He has been known to serve such foodstuffs to his guests as rock cakes that were too hard for a normal human to chew and a "beef casserole" that was actually made of some taloned creature. Guests used to his cooking would often respectfully decline his food, even if it was something of his they had never tried, such as when Harry and Ron turned down some Bath buns he had made in 1994. However, one occasion when his cooking was appreciated was when he cooked some sausages for Harry the first time they met at the Hut-On-The-Rock, which Harry noted was tastier than anything he had eaten before starting Hogwarts.
 * Tactical Thinking and Resourcefulness: Hagrid was also good both at being resourceful and thinking tactically when he was in a serious situation. When Aragog was accused of being Slytherin's Monster, Hagrid sent him to the Forbidden Forest to protect him, knowing it was the only safe place for him when Hagrid was expelled on suspicion of opening the Chamber of Secrets, also preventing Hagrid from getting in further trouble for his possession of the Acromantula. This was again shown before he was temporarily sent to Azkaban when he sent a coded message to Harry and Ron, indirectly telling them to visit Aragog which, while it was almost fatal, allowed them to discover that Hagrid was innocent and determine the location of the Chamber of Secrets, in turn also resulting in Hagrid's release from Azkaban. Another instance is when he smuggled Grawp into the Forbidden Forest without even Umbridge's attention and tactfully brought Harry and Hermione to see him while the Quidditch Final was taking place, ensuring a distraction for the other Hogwarts residents. He also successfully escaped capture on two occasions by fleeing to the same cave Sirius Black and Buckbeak temporarily lived in: first was when Umbridge tried to get him both sacked and arrested due to her prejudice against Hagrid, and the second was when he was almost caught by the Death Eaters for holding a Support Harry Potter party during Voldemort's control over Hogwarts, taking Fang with him for both occasions and Grawp on the second occasion. He was also able to successfully determine that Voldemort was going to wage war on Hogwarts when he heard his message to surrender Harry from his cave, allowing him, Grawp and Fang to return to Hogwarts in time before the Battle of Hogwarts began. His resourcefulness was also demonstrated when he used a moleskin overcoat to carry most of his possessions while traveling, which would be useful in more serious situations if he had to fight in a battle during which he would be unable to carry the majority of his possessions by hand.
 * Extreme Dexterity: Given Hagrid's superhuman size and strength, his dexterity and coordination are well above average considering he is able to handle people and objects that are extremely delicate and fragile, such as Harry when he was just a baby without the slightest bit of difficulty. This level of control over his massive form is to the extent that he is able to weave bindings from stray unicorn tail hairs to secure bandages and splints on injured animals that he finds in the Forbidden Forest. Given that unicorn tail hair is an unusually fine material, Hagrid must have amazingly deft hands to be able to craft it in such a way. His lack of control over his strength is usually in response to his emotions, but it can be assumed that given a moment to concentrate he can control his massive bulk enough to achieve incredible manual feats.
 * Craftsmanship: Due to Hagrid's hands-on style of living, he has developed great skill at building or creating things by hand, such as his clothes, his cabin, and various other items. He is a fine whittler as he crafted a flute from wood that he gave Harry for his first Christmas at Hogwarts that when played made a sound like an owl. He likely also made his commonly worn moleskin overcoat that contains a wide variety of items. Hagrid also likely built the pen that he used to hold the hippogriffs for his first lesson as Professor of Care of Magical Creatures, in autumn of 1993.
 * Social Networking: Due to Hagrid's work in the Order of The Phoenix and his skills at negotiating and making great connections within the magical community, especially with creatures of great pride such as the centaurs, he has great ability to make allies. Dumbledore specially chose Hagrid for this skill to be an envoy to the giants during the summer of 1995. Despite his lack of success due to the Death Eaters' interference and Golgomath's usurpation of the current Gurg, Karkus, Hagrid had great initial strides with the giant colony, showing his impressive social aptitude with magical creatures and beings of all levels of sapience and intellect. He also indirectly convinced the centaurs to fight alongside the reinforcements during the second half of the Battle of Hogwarts after verbally admonishing them for their apparent cowardice, eventually resulting in the defeats of many Death Eaters.
 * Music: While not a very well known skill of his, Hagrid has shown adequate aptitude for music and would sing while enjoying a drink at events. He also possessed enough skill in the area to create the wooden flute he gave Harry for Christmas in 1991, which when played created music that sounded a lot like the hooting of owls. His aptitude in music also helped him when dealing with certain magical creatures, such as being capable of playing good enough music to easily make Fluffy fall asleep in order to calm him.
 * Teaching Skills: At first, due to his nervousness, teaching inexperience and desire to teach more dangerous magical creatures due to believing their greater quality, Hagrid was a poor teacher and his teaching ability was disliked by all, with only Harry, Hermione, and Ron supporting him. In his first year as a teacher, his teaching ability was also hampered due to his first lesson being disrupted by Draco Malfoy, along with his concern over Buckbeak's safety after he attacked Malfoy for insulting him. However, over time as he gained more experience and started to teach more excitable creatures, he became good enough that although many of them still chose not to continue Care of Magical Creatures in their N.E.W.Ts, all but Slytherin students no longer complained as much about his teaching and openly admitted Hagrid's improvement, defending his teaching skills when he was sacked by Dolores Umbridge, which was to be expected from Umbridge's prejudice towards magical creatures, and expressing shock that it happened. By 2019, Hagrid had clearly improved reasonably, as he was trusted with teaching members of the highly important Statute of Secrecy Task Force who wanted to become Magizoologists and was able to do so successfully, ranging from teaching the Stamina Charm, despite his less-than-perfect version, and giving them an effective elective regarding magical creatures.
 * Leadership Skills: Although mostly taking orders from Dumbledore and after he was gone the other professors, by 2019, Hagrid had clearly become at least a competent enough leader to be trusted with handling the Magizoologist faction of the Statute of Secrecy Task Force, which clearly shows considerable leadership, being able to lead a rather large amount of magical beast handlers into handling Foundables that included Beasts without attracting the attention of Muggles.
