Star Wars

Independent sith!Harry:
Harry discovers star wars franchise as a child and uses the force to explain his strange abilities to himself. Frustration (really an understatement) with the Dursleys means that he can't reach the peaceful mediation of the jedi. Frustration with being unable progress with jedi training makes him realize there were the "bad guys" as well. Recalling what he did of the sith, and finding out more as he could, he realizes its the perfect choice for him. Unlike his attempt at becoming jedi, his sith training progresses at an absurd rate, as he unknowingly benefits from the hate-riddled horcrux in his head. Despite increasing hate and rage, Harry decides to keep a low profile in public, so that no conniving, hiding jedi would discover him, as if he has the ability, there are surely others. He progresses so quickly, in fact, that succeeding at casting force lightning is what makes him realize he hasn't done anything about his living conditions yet. Choosing a saturday morning to confront his "family", so that they'd have Sunday worth of time to make themselves presentable to the public again, he throws Petunia around with force grip and -push, force chokes Vernon to submission, and cast force lightning at Dudley to ensure the lesson goes through his thick skull. The record set straight, he claims Dudley's "second" bedroom, as he finds the one he sleeps in tainted by his presence.
Living like a king (tyrant) within the house, and offering nothing but increased confidence and his true academic competence in public, Harry makes the Dursleys absolutely miserable. Looking up an advertisement for martial arts practice at a local gym, Harry coerces the Dursleys to admit him there, and quickly whips himself into proper shape under guidance of the instructors. The instructors see Harry as an unusually intense kid, but see nothing really worrying as Harry is skilled at hiding his true nature. Between this and Hogwarts, Harry cares little for his inferiors, but has a quick temper and is easily angered, and works his frustration through the day by discreetly sabotaging bullies whenever he sees them, making them trip over convenient, if doubtful, obstacles and things like that.
Getting the Hogwarts letter, Harry interrogates Petunia for all she knows, and even rips out small amounts of information she had forgotten from her mind in the progress. Putting on a discreet public disguise, he goes to investigate Diagon Alley, discovers his fame at the book shop, and his heritage at Gringotts. Harry asks the goblins the right questions, finds out why he came to be at the Dursleys and all that, and is emancipated as a heir in his position should be on the spot, seizes all inherited assets, places a warrant for all missing articles, and puts a Gringotts legal team to bleed all they can from the "Harry Potter and -" book series's authors; last four done discreetly, of course. The goblins are obviously overjoyed at the amount suffering they get to cause at the courts. Harry attempts cloak himself with the force, and re-enters the alley to do his shopping. First things first, buying his wand from Ollivander's, who, as fortune would have it, doesn't recognize Harry because of his force cloak, sith training changing his aura, and muggle disguise. Harry is barely compatible with the holly wand, and Ollivander grudgingly sells it to him, as no other wand he would sell a schoolkid matched at all. Harry buys practical, but only the best quality of anything. Naturally he buys a broomstick to try, as well as actual contraband from Knockturn Alley, including an unregistered spare wand. Eventually, after buying ample supplies, he returns to Gringotts to pick up an untraceable portkey to a Potter house somewhere. After waking up feeling immensely exposed at his new house, Harry grudgingly decides to return to privet drive for the time being (unknowingly back to under the wards).
Harry's training picks up again as he gets Voldemort and Dumbledore as targets for his hate as well. Dumbledore first gets a bad feeling for the situation when an overly neatly written acceptance letter with proper formal nomenclature arrives from the estranged chosen one, but forgoes investigating, thinking Petunia must have overcome her discomfort for magic for her nephew's sake and kept him up with his magical heritage. Mildly displeased by this turn of events, Dumbledore pops one of his special lemon drops into his mouth to contemplate how his plans would change to accommodate Harry being knowledgeable of his roots. (Ultimately nothing changes until Harry loses his cover in the far future.)
At King's Cross Harry effortlessly finds the barrier due its magical / force presence, and boards the train long before the Weasley's arrive. Claiming a compartment, and sitting down to meditate, Harry lets quiet people join him and stay in compartment. Ron is neither quiet nor particularly tactful, and Harry "forcefully" throws him out of compartment when he finds his way there. Some time afterwards, Neville and Hermione join him, but conversation remains sparse. Talk coming to houses, Harry remarks, how ambitious it is of Hermione to seek to emulate the "greatest wizard of all time", and perhaps she belongs in slytherin; and that there is no "scaredycat"-named house where they sort cowards so he wouldn't know where Neville was going to end up in (or something along those lines).
Entering Hogwarts Harry gets to enjoy the aural side of things, but quickly finds the excessively mothering, light-riddled presence of Hogwarts irritating to spend time in. At the sorting the immensely light dominant, and immensely powerful aura of Dumbledore puts "the fear of god" into him by its mere presence, and he ends up in Gryffindor just to avoid suspicion.

Multi

Modern runes:
less cohesive all together, put central idea is a magically inclined Harry that explores the limits of magic by employing runes and ideas from muggle fiction as well.
In particular, the effects of different caryll runes from bloodborne in HP-verse. For example, Wrackspurts and most other things Luna speaks of are perfectly real, but require bloodborne-esgue insight "score" to be able to even see. Luna's insight score is of course a complex irrational number, and thus she can see all she wishes to see and avoid the nasties. By employing clothing / equipment with caryll runes inscribed, the person would be at a constant risk of gaining insight, and placing the runes directly on the body would simply cause insight, in addition to their normal / adjusted effects.
