So far this doesn't seem to be a parody. You seem to just be using the parody label as an excuse to write a straight Wrong Boy Who Lived fic. As an example, let's steal the bullet points @Perspicacity listed above and see how we can mess this them to make them parody-esque:

• A childhood of neglect, either by his actual family or the Dursleys (where he was stashed "for his safety").

Exactly @Halt 's example above: Harry claims he was abused because of very minor chores. The Dursleys are actually much kinder than in canon - perhaps they invite him on the zoo trip and Harry whines about it because he wanted to stay home and play with his Lego.

• Harry's magic was drained when he reflected the killing curse back on Voldemort, making Dumbledore and his parents believe he is a squib.

This could be a great excuse given to teachers every time Harry fails to perform a spell (or forgets to do his homework). In reality he's just bad at magic.

• The WBWL brother is named James. He is as arrogant as his namesake and a bit dim.

Harry keeps making this claim, but it's obvious from context this is just because his brother has more friends than he does. Harry mistakes his kindness for stupidity, and accuses him of arrogance whenever he succeeds at anything - most vehemently when Harry has failed at that same thing.

• Ron befriends the WBWL and the two are tight.

Ron tries to befriend Harry, who, not understanding basic social conventions, misinterprets as bullying. Possibly done so at WBWL's request because he's worried about his lonely younger brother.

• Ginny has a massive crush on the WBWL.

Harry makes this claim. In reality Ginny hides from him and acts clumsy, i.e. butter dish elbows because he's weird and annoying.

• Harry likes to read a lot and study magic on his own.

Harry only reads comics. Better yet, manga. And the magic he tries to perform are Naruto jutsu which never work. At all.

• Harry has a pet snake; this serves to further alienate him from his family.

Actually a gecko with taped up legs. The "alienation" is just him being scolded for animal cruelty.

• Sirius Black and/or Remus Lupin quietly support him despite his parents' neglect. Occasionally accompanied by being adopted into Sirius's family.

Remus suspects Harry has some kind of social developmental disorder - Harry overhears a conversation about this and wildly misinterprets it to think Remus is the only one who cares about him and thinks he's special. Sirius hates the little bastard but puts on a good poker face to support James.

• Harry is sorted into Slytherin or, in a pinch, Ravenclaw. Never anywhere else.

The hat considers putting him into Gryffindor because he has a rash. Harry cries in front of everyone. The hat quickly agrees Slytherin to stop him from wiping snot on it.

• Harry becomes a stunningly Machiavellian politician within a few months of matriculating into Hogwarts.

All an elaborate lie he invents to excuse the fact that he has no friends. He spouts inane bullshit at other Slytherins, and they more or less unanimously just tell him to go away.

• Harry and Dumbledore don't get along.

Harry has never interacted with Dumbledore in any way.

• Harry is a better flyer/quidditch player than his brother (who is still pretty darned good).

Harry makes this claim, but his mum doesn't let him fly.

• Lily has a change of heart and is redeemed later on by a modest act of kindness to Harry.

Harry was breastfed until he went to Hogwarts.

• Harry is the older twin and therefore the heir; this raises tensions among his family.

They're not even twins, although Harry makes this claim frequently. They were born eleven months apart.

• Good Slytherins become Harry's posse. They all act like little politicians.

On rare occasions somebody will humour Harry and respond "in-character" to his Machiavellian bullshit. Out of pity.

 

These things I have thought of, I wanted to have the hat deem Harry as having only Gryffindor qualities, making Harry threaten the hat, whine and cry, where the hat, fed up, sorts him into the house of his choice. And Harry's acts all political but he doesn't have a little bit politics. His friends all know it but none of them points it out due to his nature to cry whenever somebody criticises him.

Ginny had a crush on him at first but he didn't like her because he thought that she was playing him on.

Harry thinks his brother looks like a snob and all, but it is because he has bad eyesight.

And the reason why his parents forgot him was because he had accidently cast an obliviate charm that slowly affects everybody and made them forgot about him when he was attacked by Voldemort.

Hat thinks he is super rich, but most of the people like Malfoys have more than that a year as they indulge in businesses and such.

Harry gets many abilities due to his nature as a mutant kryptonian but most wizards have the ability to counter them. Harry has multiple animals but that is such a common thing that nobody takes him seriously. But Harry doesn't know about it cause no books in the library mention this as they are mostly written in the 16th century.

Harry gets a super wand but he got it from a Knockturn Alley store that sells mismatched wands. And all the dark artifacts he saw in the stores were unknown to him as they were created after the books were made.

He has a big arsenal of spells but other wizards have the same spells, the only difference being they are modified.

I am trying to do this to most tropes I found, I admit I got this idea to do this tropes only after I uploaded the first chapter and found that it is plainly a WBWL a story, so I'm rewriting the first chapter.

 

Damn @CareOtters, write this shit my dude.

 

I did a rewrite of the first chapter a bit shorter. It is written in first person, an idea I got from reading the seventh horcrux. I just wanted to check your input on the rewrite before posting it. So here it goes,

The One Where It All Began
OR
How I Became A Soul Jar
​

Griffin(More like Mad) House, Godric's Hollow

I was pretend-sleeping in my room, to my mother's song, which I was barely tolerating. My twin brother was sleeping next to me.

My father was playing a game of FruitSqueeze on his mirror. Or admiring himself, I never could tell. In another corner of the room, there was Sirius, flirting on the phone, and Remus was eating raw meat in another part of the room. My grandparents on my father's side were staying in the basement, which became haunted by a ghost after they moved in. There were moaning and screaming sounds coming from it every night. My grandparents on my mother's side, they were muggles, so they were staying in the fourth floor, with their two cows, three goats, five hens, three ducks and two dogs. In two words, a barnyard. My aunt Petunia and her husband Dursley with their one year old pig Dudley were staying in the third floor. Funny people, my aunt and uncle, saying that the pig was their son. Honestly, I don't know why all these people came here, just because we have a five storey house which was fideliused due to some insane dark lord, who was hinting my family and also coincidentally, also after them, didn't mean that they could come and stay here. I barely have any space to move. I try to tell my parents about it, they just look at me with love in their eyes and give my food, take me to potty, or play with me. Are they deaf?

But if my bro Jim has any problem, they have no problem solving it. And what he says is not even legible, all he says is Wha, wha wha.He's a total wuss.

Back to my situation here, my mother was still singing to us, and I was still pretending sleep, and I am pretty sure my brother was too. But you can never tell with him.

$ SLEEP, MY BABIES $ She screeched, I cringed at her voice. Suddenly, a blast was heard, and I opened my eyes, to find out who did the great thing of stopping my mother.

My room was empty of anybody except for my perfect little brother, who had woken up. Then my mother ran back into the room, closing the door behind her. There were sounds of intense fighting downstairs. Sounds of spell incantations, their impacts, cries of pain and embarassments, animal sounds, and the stench of something nasty spread through the house. It reminded me of... my diapers!

Our mother hugged us close to her, and quietly said, "Jim, Harry, my babies, I don't think I am going to be here for more time, but always know, your mother loves you, your father loves you, your grandfather loves you, your grandmothers love you, you aunt and uncle love you, though they don't show it and Dudley, well Dudley doesn't like you that much."

Well, no shit. I thought. Dudley hated me and my brother, I was pretty sure he hated our parents too, except for our food, and out television.

As I was deep in thought, the closed door was blasted out of its hinges by a grey light. And In came someone warped in a black cloak. I could see his ghostly face and I shivered at it. He had blood red eyes, reminding me of my mother's lipstick. His face was as pale as my vampire neighbour who claimed to not be a vampire and his nose, OH MY GOD , HE HAD NO NOSE!

I was scared out of my wits. Noseless People had always been the source of my nightmares (and wetting and soiling my bed at night). I couldn't even believe my eyes, but it was happening. I screamed at the top of my voice as he started walking towards us,

"OH MY GOD, I DON'T WANNA DIE, I AM TOO PRECIOUS FOR THAT, PLEASE, ANYBODY, PLEASE SAVE MEEEEEE!"

Suddenly, as if she were a superhero, my mother sprang in front of us and , herblong red hair fluttering like a cape, and with the huge P in the chest of her T-shirt, she was all set to be Potter Woman. Instead of shooting with her laser eyes, she got on her knees and begged, "Please, not the boys, anybody but the boys, not the boys, take me instead"

"Step aside, silly girl" said.

"Please, not the boys, I will do anything for you" My mother begged, and I felt my first string of love towards her. She should be proud, it was not easy to win my love after all.

"I'm warning you, silly girl, step aside." said.

"Please, I bill wo amyfing bor wu" My mother begged again. I had a strong feeling that it was not what she meant to say, as a huge barrage of spit flew from her mouth to 's face. Ewww.

seemed to have had enough, "Oh, Now you are going to pay, silly girl." He said and instantly shot a bolt of red light towards her. She fell face first on the floor.

He the made towards us, my brother was crying at the lady lying on thw floor. I decided thst I had enough. This lady had sacrificed her life and pride for us, if she had the guts to negotiate with , I, who is more awesome than her, certainly would have. I stood up, gathering all my awesomeness in my eyes, in an attenpt to intimidate . It worked, unsurprisingly, as one who had the power to attempt stare at my awesomeness had yet to be born.

He stopped, his eyes lingering on uncertainty. He looked at me, then my brother, then me and again my brother. He then pointed his wand at me and snarled "Your awesomeness is no match for mine. HAHAHA. Avada Kedavra"

A green light flew towards me, and I, in an attempt to save my greatness, pushed all of my awesomeness towards the spell, forming a golden shield of awesomeness. The spell hit the shield and ricocheted off.

Unfortunately(fortunately, if I tell the truth) it ricocheted off to my brother. I immediately extended my awesomeness powered shield towards him. But my shield was not powerful enough, the spell was only coloured down. I saw the spell speeding towards my brother and hit him, but wait for it, wait for it... he reflected it back to . sxreames in the same tone I used when I screamed. The spell hit him and instantly his body was torn to shreds, I felt satisfaction build up in me as the fact that I was the cause for 's demise. But alas, fate was not too lenient towards me. 's body was destroyed but there was something that still remained. I watches in growing horror as the smoke like thingie from him flew away from my room, but before he flew away, a piece of him broke of from the rest as if chocolate and flew into me.

I felt intense pain in my forehead, one that I had never even experienced before. I screamed and cried. Eventually, it went away, but I could still feel the burning where the piece had went in in my forehead and I felt a scar. I immediately realized that I had to research plastic suregeries on the future. This scar would be a problem for my photos in the future.

I looked at my brother, he was asleep, appaprently tired from that reflection thingie he did.I looked at my mother, she was dead, but I sensed something wrong about her. I looked at her for a bit more time. And you will never guess whst happened, she twitched. I saw her dead toe moving, soon this spread to her entire body. To my disbelief, she woke up. She woke up and started towards us. I moved away from her as I was pretty sure zombies don't coddle their children.

Pretty soon, most of the people in the house began to flock into the room, each of them being saying that they had been stunned by . There was some mourning for my dead aunt and uncle but Dudley the Pig had survived. Our parents carried us, after making sure that we were alright, and I reluctantly allowed them as my current body size was

The crowd in the room was making me unable to breathe, just as I thought it couldn't get worse, a bunch of people in weird lookinh robes burst into the room, and the one who looked to be their leader was a weirdo with a beard, a beardo.

"You are not dead!" Beardo shrieked.

"No, we are not. No thanks to you, Albus" My mother said.

"But I thought... You... Supposed to be dead..." Beardo spluttered.

He then took his wand out his pants and cast a silver spell on himself. He then began to speak, calmer than before "Okay, sorry for my earlier behavior."

"Apology accepted" My mother said.

"Now who is the boy who lived?" He asked jovially. As he said that, I got a chill in my spine.

 

You guys have missed one of the biggest tropes of all: Harry has a younger sister (or maybe twins) whom he fucks.

 

We need some sources for that.

 

Younger sister can be seen in HP and the Heels and GO Rise From Dust.
