There are two, actually. The first one is hosted on Seventh Sanctum.
http://www.seventhsanctum.com/generate.php?Genname=hpstory

Harry Potter and the Blasphemy of Xanadu
Harry Potter and the Crusader of Hufflepuff
Harry Potter and the Diadem of El Dorado
Harry Potter and the Drake's Darkness
Harry Potter and the Serpent of Mu

Cool stuff.

The second one technically isn't a HP name generator, but I noticed one day that Magic: The Gathering card names work very well as HP titles.
http://gatherer.wizards.com/Pages/Card/Details.aspx?action=random

Harry Potter and the Gruesome Encore.
Harry Potter and the Bane of Hanweir.
Harry Potter and the... Plains.

Okay, well they can't all be winners. But still, check it out and see what you come up with. Just click "random card" to get new ones once you're on the site.

Oh, and I'm new here so if this is in the wrong section could one of the mods move it? Thanks.

Edit: Ooh, Harry Potter and the Glyph of Doom!

 

1st Generator:
Harry Potter and the Dwarf's Agony
Harry Potter and the Bow of the Magician
Harry Potter and the Dementor's Savagery
Harry Potter and the Salve of Hogsmeade
Harry Potter and the Wraith of Dreams
Harry Potter and the Unthinkable Slayer
Harry Potter and the Warped Idol
Harry Potter and the Necromantic Transformations
Harry Potter and the Call of the Traitor
Harry Potter and the Conjurer of Light
Harry Potter and the Death of Atlantis
Harry Potter and the Silver of Shangri-La

I thought the name generator was rather funny. Now it´s time to try to write a story for each one of the titles.

 

from the first generator:
1)Harry Potter and the Bloodstained Orb
2)Harry Potter and the Death Axe
3)Harry Potter and the Deck of the Dragon
4)Harry Potter and the Flame Grave
5)Harry Potter and the Flame of Camelot
6)Harry Potter and the Great Exorcist
7)Harry Potter and the Scribe of Infinity
8)Harry Potter and the Shroud of the Traveller
9)Harry Potter and the Sword of Bones
10)Harry Potter and the Wand of Camelot
1,2,5,9 and 10 seem like interesting plot bunnies.
From the second
Harry Potter and the Insatiable Souleater
seems like a 'master of death' fic or the first dementor. might be interesting.

 

...or both. :mrgreen:

 

Harry Potter and the Cudgel of the Waitress

"I've been telling you Ron, she is up to something," Harry whispered as their waitress strutted away, hips swaying. "Definitely."

"Mate," Ron said shaking his head. "I could tell you a couple of things she has up, but you've got to stop looking for conspiracies everywhere. Hogwarts is over. No one is after your life."

"But what if she is?"

Ron shrugged. "At least, it looks like a good way to go."

"No. I'm sure she is hiding something," Harry said, unrelenting. "Some sort of unpleasant surprise."

And you know, folks, it was not a cudgel after all, if you catch my drift.

 

Alrighty, I'll give it a wirl.

And we have:

Harry Potter and the Amazon of Steel (feel like there is a penis joke in here somewhere)
Harry Potter and the Book of Infinity
Harry Potter and the Decanter of the Sorceror (alcoholic harry)
Harry Potter and the Diviner of Forever (Trelawny time travel fic)
Harry Potter and the Drum of Forever
Harry Potter and the Enraged Dementor
Harry Potter and the Foul Darkness
Harry Potter and the Heavenly Inquisitor (Umbridge spoof)
Harry Potter and the Infinity Wisdom
Harry Potter and the Scribe of Lemuria
Harry Potter and the Sigil of Azakaban
Harry Potter and the Skull of the Necromancer
Harry Potter and the Spy of Gryffyndor
Harry Potter and the Summons of Time (Sounds like a Joe title)
Harry Potter and the Mysterious Irritant (The only worthy story title in this batch)

 

Some titles with my notes below.

Harry Potter and the Grimoire of Limbo
(The version of DH we've been all waiting for.)

Harry Potter and the Lost Ring
(So, Dumbledore fucked up big time in the Gaunt Shack?)

Harry Potter and the Venom Chamber
(Now that's just lazy, this is basically CoS!)

Harry Potter and the Flame of Ravenclaw
(Yeah, I bet the Diadem was really nice in that Fiendfyre.)

Harry Potter and the Prisoner's Blackness
(GET IT? CAUSE THE PRISONER WAS NAMED BLACK!)

 

1st generator
Harry Potter and the Chime of the Golem - I could make something out of this.

Harry Potter and the Spear of the Prophet - Spear of Destiny fic, perhaps?

Harry Potter and the Armor of Hufflepuff - There was a reason Helga's house was renowned for hard work, the other three louts sat around while she cut down the goblin hordes and cleaved the path and grounds of Hogwarts out of the Forbidden Forests' heart

 

Look, if you're going to post heaps of those, at least either post the better ones, or have some context for the name. Since, you know, we can get random lists from the link, too. Or take a first outcome, and write a couple of words for it. I'll try another one... (Edit: Aimed at Thyestean, more than anyone else)

Harry Potter and the Foul Concrete

Harry's first mistake was eating a sweet from the Twins.

His second mistake was underway. For five hours straight.

Harry, red in the face, pushed, until his eyes bulged out, until the stomach began to scream death threats in parseltongue.

The third mistake was not his.

Hidden in the pipes under the lavatory, The Basilisk, King of All Serpents, never knew just what hit him.

 

To be honest the "anyone else" option produces much more interesting titles.

For example "Victor Krumm and the Elf's Savagery" [sic] sounds like totally depraved sadomasochistic Dobby/Krum story.

 

Narcissa Malfoy and the Ritual of Hufflepuff
Why does this sounds like a smut fic?

 

Bwahaha - there's a GL Self-Insert if e'er there were.

 

These seem like they'd lend themselves well to a HP/Dr Who crossover.

Obvious Squib!Harry story - although it could equally be an alternate title for that story of Calz's that I'm ashamed to say I can't remember the name of off the top of my head (Catharsis?)

Now that's an intriguing title. I'm picturing something akin to Wastelands.

A Deathly Hallows AU, that focuses more on the Half Blood Prince, perhaps? Or maybe something spiralling off from some secret knowledge from a Death Eater.

 

Now you know that giving Voldemort the Death Star would just be unfair...

Also, "Infinity Infinity" :facepalm. At least "Infinite Infinity" would make more negligible sense.

 

Godric's response to the diadem, perhaps?

Takes place in the Felldark of the Undershadow. Harry can be mentored by Jim Darkmagic.

Pretty sure Harry gets bonded to over 1000 women in this one, all of them having bisexual tendencies. Maybe he even becomes Duke of magic or something. He can also turn into a dragon.

Throw in some vampires and shit, turn this bitch into a trilogy.

 

Would read that, watch the eventual movie and buy Lord Voldemort's poster.

 

Alright, another try, this time seven titles to make an alternate main series.


Harry Potter and the Angel of Flame
Heliopaths are real and are much more common. Voldemort used them in the first war and now they are back.

Harry Potter and the Betrayer's Sigil
Obviously, this means Sirius Black escaped Azkaban earlier in this series. But what would be this sigil? Could it be that Mr. Black knows how summon demons? I can get behind that.

Harry Potter and the Death Eater of Limbo
Nice, we get rid of the Horcrux in Harry earlier, meaning he actually has to earn his victory, cool. But who is that Death Eater? Maybe Snape dies and he is the one meeting Harry in limbo instead of Dumbledore?

Harry Potter and the Drum of Atlantis
Voldemort (who is back at this time, of course) travels to the sunken ruins of Atlantis to recover the legendary Drum. This artifact would grant him untold powers and it is up to the duo of Harry and Dumbledore to destroy it.

Harry Potter and the Exalted Flame
Either this is a reference to the Heliopaths from the first book, Phoenixes or we're dealing with an Elementalist Harry here. I'd hope the last one is not the case.

Harry Potter and the League of Avalon
So, Morgan le Fay. Voldemort's ally? Maybe she made Horcruxes too.

Harry Potter and the Mystery of Mysteries
This title obviously refers to the Department of Mysteries. Naturally, I'm assuming it is about the ever-locked door.

 

Seven Harry Potter books based upon random titles? Let's see...

Harry Potter and the Arch-Angel of Azakaban
In this universe, I don't think Voldemort was killed. Rather, he was weakened by baby-Harry and sent to Azakaban. Azakaban is guarded by the Arch-Angel, a fearsome magical being sworn to never let any prisoner escape. Unfortunately, the unthinkable happens. Loyal Death Eaters break Voldemort out and the Arch-Angel sets out to bring him back. The problem: it thinks Harry is Voldemort. The Death Eaters have swapped the two in the Angel's eyes.

Harry Potter and the Axe of Visions
Harry has escaped the Arch-Angel of Azakaban but it still refuses to recognise Voldemort and return him to his prison. Fear grows in the magical world but Voldemort is not yet ready to act, still weak from his defeat at the hands of baby-Harry. He remains in hiding, where no mortal wizard can find him. In this interregnum, the last living dwarf comes to the Order of the Phoenix and suggests a solution: the Axe of Visions, an ancient dwarven artefact which can restore truth to the Angel's sight.

Harry Potter and the Dwarf's Legends
During the climatic confrontation of the last book, the Axe of Visions was shattered, forever putting Voldemort beyond of the Arch-Angel of Azakaban's power. Doing so, however, has triggered an ancient dwarven curse: Whoever breaks the Axe of Visions must reforge it into a new thing. With the last dwarf's help, Harry must use the shards of the Axe of Visions to delve into the history of the dwarves. He learns how this now fallen race still shapes the Wizarding World even today.

Harry Potter and the Infinity of the Drake
Voldemort has gathered his supporters and is ready to regain his power. He plans to use the nigh-infinite power of the Drake (an ancient dwarf construct, much like the Arch-Angel) to restore his power. Harry must stop him or the Wizarding World may be doomed.

Harry Potter and the Protector's Execution
Voldemort has sacrificed the Infinity of the Drake and regained his power. His first move is to strike down one of the few beings who could oppose him: the Protector, the last living dwarf. With his death, much of the ancient dwarf machinery which underpins the Wizarding World begins to fail, including the Innullius Engine which allows them to hide from the Muggles. Harry must now face a resurgent Voldemort and stop the collapse of the dwarven machinery.

Harry Potter and the Shield of Fire
Harry is now the Protector, the lynchpin which keeps the ancient dwarven machinery running. With it comes mastery of the Shield of Fire, an order of Arch-Angel like spirits dedicated to protecting the universe. However, when Harry turns these spirits against Voldemort, what they were protecting the universe from invades: the Outsiders.

Harry Potter and the Silver Drum
Voldemort has forsaken the last dregs of his humanity and taken his place as the Outsider King. Even the dwarfs, at the height of their power, could not defeat the Outsiders, merely hold them at bay. To have a chance to win, humanity must step out of the dwarfs' shadow. It is time to sound the Silver Drum. It is time for a new age to begin. (The Silver Drum is probably what Harry made from the fragments of the Axe of Visions).
