After riding the centaurs, the centaurs feel that he must return the favor. Harry does not survive.

 

Harry, startled by Myrtle in the prefect's bathroom, cracks his head on one of the many elaborate faucets, and drowns in the tub.

 

PS/SS: Taking the initiative for once in his life, Wormtail gets up in the middle of the night and stabs Harry to death with Ron's potions knife. Cleverly splats Harry's blood on Ron. Ron goes to Azkaban for Pottercide.

 

Luna believes that the Snorwumples are after Harry. None have ever survived them, so she executes a mercy-killing for Harry, that he may avoid a more painful death.

 

This one wins the thread.

Anyone seen a thread with Bellatrix!Luna with Dark!Harry? That might be awesome.

 

Luna would probably be an interesting Bellatrix; I could see her as the kind of person who, if given a single wet sock, a piece of pie, and a soft cushion, would find a way to turn use those three items to inflict inventive tortures on her victims.

To contribute to the thread's primary purpose: Harry decides to take a round-the-world vacation after killing Voldemort, and ends up catching a nasty STD from an underaged prostitute in Thailand.

 

When Hagrid is banging on the door to the little island retreat where the Dursley's take Harry to avoid his Hogwarts letters, Harry gets upto answer the door just as Hagrid decides to knock it down, crushing Harry.

Or, When Hagrid puts a pig tail on Dudley, Harry catches swine flu and dies.

 

On topic: After a particularly intense potions lesson, Harry goes to dinner and forgets to wash his hands. Dies promptly of contamination.

 

Better: chokes on pretzel.

 

Sitting across from Dumbledore, Harry chokes on Lemon Drop as Dumbledore laughs evily at his engenius plan.

 

The stairwell moves unexpectedly and Harry falls off of it to his death.

 

An unfortunate accident swings harry into a different dimension. Unfortunatly in that dimension everyone lives under water with gills. Harry promptly drowns.

 

Harry finds out Ginny was cheating on him with both Snape and Malfoy, goes on a rampage and kills all three of them, and then himself after he finds out she was going to have their disgusting child.

 

In despair over the death of his beloved godfather, Harry slits his wrists in the bath. Turns out magic can't keep you alive and wizards bleed out like everybody else.

 

Harry manages to convince Ollivander to make a custom wand soaked in basilisk venom. 5 minutes later, Harry dies from a splinter.

 

How the hell did I miss this one? That is heroically awesome.

I elaborated on the Luna and the Snorkwumples.

After defeating Voldemort, Harry leaves the wizarding world to join the American pop boy band sensation, the Jonas brothers. Harry soon becomes the most popular member of the group with his grown out pony tail, fanged earrings and hot leather pants.

The other members in their jealousy conspire to bring Harry down by getting him hooked on cocaine. While Harry is high, he loses control of his uber magical power levels and kills the entire band. Harry commits suicide when he realizes what he has done.

 

First book:

Harry shouldn't have freed a Boa Constrictor while he was standing near to it's cage.

In the girl's bathroom, Ron realised he really should've listened to Hermione in the charms lesson.

Second book:

Arthur Weasley didn't understand that much of cars and their fuel needs.

Harry thought Tom Riddle wasn't that bad. Maybe he could help him in the fight against Voldemort, teach him a few spells or something. So, he didn't destroy the diary but took it with him.
His lifeless body is found at Privet Drive after the school year started.

Third book:

Lupin wanted to be as prepared as possible, so he went to Hogwarts before the train was even outside of London. Nobody on the train could cast a patronus.

Snape charmed the Shrieking Shack, so that noone could get in or out. Too bad that he fainted after being attacked by Harry.

 

In a suprisingly ingenious move, Arthus Weasley charmed the car to run on the driver's power. Too bad Ron is a powerless wimp, unable to sustain both himself and the car ...

 

After going through a power boost and becoming the Heir of Merlin on his 12th birthday, Harry decides to drive a car tailored to Arthur Weasley's somewhat meager power level. He is promptly launched into the stratosphere where he suffocates.
