Severus Snape

Snape could appear cold, cynical, malicious, bitter, and sarcastic. He had a commanding presence that exuded gravitas, authority, and control; like Professor McGonagall, he had the ability to keep a class quiet without effort. He tended to hold grudges and was extremely spiteful toward those whom he disliked. In particular, he disdained Gryffindor students, considering them to be arrogant and attention-seeking. Descriptions of his social interactions as a child suggest that he had poor interpersonal skills and that he may have suffered from depression.

Snape is described as a thin man with sallow skin, a large, hooked nose, and yellow, uneven teeth. He has shoulder-length, greasy black hair which frames his face, and cold, black eyes. He wears black, flowing robes which give him the appearance of "an overgrown bat".

Severus Snape, as a young man, was an extremely insecure, vulnerable, and painfully embittered person with a colossal inferiority complex. From the year dot, he strived to be part of some greater cause for the sake of recognition, admiration, authority, or if need be, fear. He grew up in complete and utter poverty under a vicious Muggle father who likely abused him due to his magic and a submissive Witch mother, leading him to be a very fearful person. This also drew him towards Lily Evans, to whom he developed an increasingly powerful love for, however, though she regarded him as a friend, she never was shown to return any of his romantic affection.

Snape was a determined and highly driven man, and quickly developed supreme confidence in his own talents and abilities. In his own right, he was an extremely powerful Wizard, so this assurance wasn't unjustified. He would also become critical towards the magical powers of others, particularly Hogwarts students he didn't like. However, despite his immense prowess as a sorcerer, Snape relied on his genius-level intelligence and power of mind to survive in a world where magical powers were considered the defining trait of everyone around him instead of logical thinking.

As a teacher, Snape was externally bitter, cynical, precise, cold, sarcastic, aloof and apathetic. He was very direct in his opinions of others and didn't regard people's feelings very highly while having patience for any reckless or rude behavior. His standards for his classes were much higher than that of the other professors, as he only allowed students with the very best grades (an Outstanding mark) to continue into advanced Potions class on N.E.W.T. level. He seemed to favor Slytherins against all other Houses

Snape projects an aura of mystery – he’s an impenetrable fortress. An island. Some might say really great at maintaining boundaries. Good luck trying to find out who the real Snape is – arguably only Dumbledore had that honour. Snape’s air of mystery wasn’t just down to his secretive personality: he also happened to be a very talented Occlumens.

he could transform into a bat-like creature and seemingly take off into the sky, unaided. It came in handy when faced with an irate McGonagall, Flitwick and Sprout – why face consequences when you can, quite simply, soar off into the night? But it also showed just how well learned a wizard Snape was. There was only one other wizard who had been known to be able to fly without a broom: Voldemort. While Snape was a famously complex figure, he often used his set of magical abilities for manifold reasons.

Speaking of Snape’s creations, his ingenuity as the Half-Blood Prince went far beyond tinkering with potion recipes – he created spells of his own. Not any witch or wizard would have that capability. But for Snape? He didn’t just stop at one spell. No, he made multiple. Some were useful, practical and even exhibiting Snape’s lesser-seen sense of humour – such as Levicorpus which hoisted the target into the air by their ankle. Though after Snape’s run-in with the Marauders, we saw a darker side to that spell. Others played into his obsession with the Dark Arts. Sectumsempra was a particularly violent spell, and it is rather troubling that a teenager came up with it. When Harry used it against Malfoy, he almost killed him. So yes, Snape had the power to create his own spells, but great power should always come with great responsibility.

Severus was a talented wizard even in his childhood. It was apparent through the notes and scribbles in his potions textbook that he made time during classes to invent curses, charms, and clever potion innovations, while simultaneously learning the required textbook lessons.
