The official logo of Demonbusters.

The Halloween 2k9 event took place on October 22, 2009, while the full event kicked off on October 28, 2009. The title for the event was "Demonbusters". There were two sides to choose from The "Light Side" and The "Dark Side".


Long ago, a bitter fight between two Gaian demigods left them powerless and imprisoned for centuries, biding their time until they could rise again. Now, a dark deal with the King of Halloween has restored their power... one is hell-bent on flooding Gaia with demons, and the other is building an army to stop her.

Event Beginning: First Day & Rest of the EventEdit

  • Oct 28

Without seeing an official announcement, many Gaians found they they could Trick or Treat in Gold Shops and in Gaia Towns.

Two subforums opened up in the forum Halloween 2009: Demonbusters:

In zOMG's Barton Town, there were mini events to gather Halloween related recipes and ingredients by fighting Werewolves and Vampires.

SKITTLES® was the main candy collecting source for Gold Shops and in Gaia Towns, in Gaia Towns, 1 Skittles would count for one piece of candy, while a bag of skittles would count for 11 pieces of candy.

  • Oct 22: Demonbusters: Get ready for our 2K9 Halloween event! [1]

This is Cindy Donovinh reporting for Gaia 9 Action News. Strange things are afoot as Halloween approaches—as most Gaians know, the end of October always seems to bring plenty of pandemonium.

Many Gaians have reported receiving cryptic messages from two strange organizations: B.O.O. and S.I.N.; while these organizations still haven't opened up their membership to the public, they seem to be making one thing clear: soon, Gaians will have to choose a side.

Along with this, Gaian archivists have discovered the first few pages of a long-lost tome about Gaia's ancient history—pages which may shed light on what these two organizations are all about. We expect that new storybook pages will be revealed in the following days.

All signs point to October 28 as the date of this year's Halloween chaos. To begin reading the story and learn more about B.O.O. and S.I.N., visit Gaia's Demonbusters homepage.

  • Oct 27: Demonbusters: Read the Storybook! [2]

This is Cindy Donovinh for Gaia 9 Action News. Gaians have been abuzz with speculation over tomorrow's Halloween chaos, and today we're one step closer to understanding the strange events leading up to it.

The Demonbusters Storybook is now complete. It tells the tale of two demigods getting into an argument a thousand years ago... an argument that seems to be flaring up again in the form of two competing cults: B.O.O. and S.I.N.

To read the storybook, just visit Gaia's Manga Archive:

  • Oct 29: Demonbusters: The Battle Begins! [4]

Aha, look what FUN I've created! Just in time for my favorite holiday, I've released quite a scourge on the world! I've uncaged The Sentinel—who's been trapped in a box for a thousand years, boiling with rage and sssslowly going mad—and now she aims to build a dark army and create a new world of unholy demonic inssssanity... but her old nemesis, The Overseer, is building an army of his own to stop her.

Fight for your future, Gaians... fight for your very livesssss! I'll just sit back and enjoy the fireworkssss...

"The time has come to fight for the fate of your world, Gaians: will you join the Sentinel's Infernal Nation, or the Benevolent Order of the Overseer? For a little background, check out the Demonbusters Storybook and our new Demonbusters manga!

Visit the Demonbusters event page to choose a side, check out the game tutorial and start waging war.

Be careful which side you choose to join, because you can't switch teams. Each side gets a special event skin which can't be sold or traded... but only the winning side will get to keep their skin when the event ends, so fight hard!

Choose Your Team

The event will run until November 6th. Let the battle begin!

  • Nov 4: Demonbusters: Play Now Before It's Too Late! [5]

Hello, my pretties! The battle between my little playthings The Overseer and The Sentinel is still going strong, but it won't last forever. If you haven't yet chosen your side or claimed all the precious items, you'd better hurry! November 6 is your lasssst chance to play. After that, who knows what'll happen? Demons everywhere? A new clamocracy? Or something else entirely? Mwahah!

Play Demonbusters!

Hail, Gaians! It seems the admins have another dispatch for you to read...

In celebration of its one-year anniversary, zOMG! is getting all seasonally sensitive with a whole host of Halloween horrors. Vampires and werewolves are out for blood, launching new attacks every night (in game time). These strange creatures seem to be emanating from portals appearing all over the place. Rumor has it that if you fight your way through one, you'll end up in a nest full of baddies... not to mention a lot of potential loot.

You can also expect the return of pesky pumpkin fluffs in Barton Town, plus nightly trick-or-treating with the NPCs (also in game time).

To get in on the action, just load up zOMG! already!

While there, be sure to check out the new voice chat feature for crews. It'll save you from having to type so much during those life-or-death battles.

Event ConclusionEdit

Cindy Donovinh: AnnouncementEdit

  • Nov 9: Demonbusters: Read the Conclusion! [7]

Halloween has come and gone, bringing the titanic struggle between The Overseer and The Sentinel to a close. This is Cindy Donovinh reporting live from a battleground riddled with smashed pumpkins, dead worms, and so much salt water. After a long and grueling conflict, the Infernal Nation triumphed, leaving the Benevolent Order in disarray.

As a result, the members of the Infernal Nation will get to keep their unique skin, bestowed upon them by The Sentinel. Followers of The Overseer won't go home empty handed: their skin will be transforming into something of a "consolation prize."

For a full recap of the final moments of the battle, be sure to check out the latest manga!

Read the Demonbusters Finale!

H2k9 battlefield finalday

It is The Sentinel and her S.I.N. Followers who were declared the Winners of the event, included with this announcement were 5 Manga pages.


  • Nov 9

As The Overseer shows his true form, he and The Sentinel charge each other for a final attack. Sentinel overpowers Overseer, while Bruce Hardcastle spins Ricky Baudelaire over his head. Gino Gambino is about to be attacked by a sentinel being but Sam jumps in front of it; hitting it with a wrench. As Sentinel prepares to strike the Overseer with a mace, Jack steps in and collides their heads together and tosses them into the air, laughing that they are "Baby-Gods" and will be stripped of their powers. Also chiming that Gaians shouldn't eat too much candy; the Followers are confused and irritated at this conclusion.

Overpowered by Bruce, Ricky is being choked. But Jack grabs Bruce and shoves a potato down Bruce's throat, killing him again, though technically he was already dead.

Jack then runs off into the night laughing, while Gino is left naked and confused.


  • Nov 11

The manga starts off with The Overseer and The Sentinel waking up on the battlefield, both realizing that they lost their godship.

But they stood up and continued to fight, with Overseer proclaiming: "Do you really hate me so much?!". Sentinel clearly being the most upset about being mortal, threatened to end Overseers suffering early.

But something catches their gaze, it was a humble earthworm laying on the ground, as both stare at the creature, the story ends by mentioning how much time has passed without the aid of the two demigods and stating that "It had never needed anything from them at all".

Criticism: Skins & Comparison to 2005Edit

During the tutorial of the event, it was stated that only ONE side would get to keep the official event skin, and that skin would be soulbound to the winner(s). Due to soulbinding being unpopular with the population, there were a lot of negative threads about it. Though there were a few positives threads, stating that having a soulbound skin would bring the feeling of accomplishment.

Some used the Grombie skin as an example for their posting, stating that exclusive skins from events leads to elitism. There were various feedback threads saying what should and should not happening if one side didn't win. One purposed that both skins should be removed after the event is over, another purposed that the war should end in a tie.

On miscellaneous note, some didn't like either skin and compared them to other skins already on the site: "Twilight Sparkling Skin" and "Superior Form's Fire Skin". One User pointed out that the B.O.O. skin looked eerily similar to a harlequin baby. Others however did like the skins given, and worked the event to keep them for their team.

>Dev response Edit

Fleep is quoted as saying:
We are planning on removing the skins of the losing team, and we are fully aware of the consequences of such an action. We don't do it with bad-intent, quite the opposite. We all feel strongly that having real consequences for losing and real benefits to winning creates a level of competition that we think enriches events. We've done enough of them to know certain things that work and certain things that don't.

Users will be upset, but everyone's upset when they lose. They will still walk away from the event with a buttload of free items and a bunch more gold. We also think it makes sense in terms of the story and world. We hope that it will make this event a more memorable one (though some users will no doubt say "Yeah, I'll remember it as the one where Gaia screwed its users over!")

In the end we feel it's a net positive for users. I don't need to point out to anybody that we don't stand to gain by taking away your skin except in the sense that we think it'll make it a more intense event, and the more you guys like it and spend time playing it, the more successful we'll consider the project.

Criticism: "This Event is Rigged!!"Edit

As the event went on during the week, there were some glitches with the weapon firing and Experience points dropping; with that were demanding posts to fix the problem. During this time many Gaians posted in the Site Feedback and GCD that the event was rigged, and that Gaia Staff had already chosen a winning side ahead of time. Devs tried to assure Gaians that the rumors of the event being rigged was false.


There was a survey annoucement as the event was coming to a close, Fleep reported that H2k9 received highly positive reviews.

Many Users did enjoy the arrival of the new NPCs, Overseer and Sentinel, the amount of prizes to be won, and the new Jack items. And even though there were some issues with the weapon firing, Users found the event overall very unique in comparison to other Halloweens.

Glitches & ProblemsEdit

As no event on Gaia has ever gone on without glitches, the 2k9 Halloween event was no exception.

Glitches: Site & ForumEdit

  • Due to the massive influx of users within a small amount of time, the servers were overloaded, causing Missions being completed not to register. The Gaia Staff thought they could lessen the impact by only letting in a few Gaians at a time.
  • But one fact was, the event was not meant to be started early. So the solution was to put it on hold and open up the Demonbusters page on the 29th. While the event was put off till the next day, the Demonbusters Mainpage was blocked from Users. Though for some reason there was an error and Users who had a UserID ending with 0, were able to still see the page and play Missions. Many did not realize the page was suppose to be cut off. When the next day came the page was open and missions back up, the Score on both sides were reset.
  • On Oct 28, around 6:30 PM (EST) Toting was disabled in shops till the 29th.
  • When Gaians first entered the Demonbusters page, there was a green arrow that would direct them on how to get started. So when clicking on the screen a popup would read: "Click the button indicated by the green arrow!". Even though being clicked and the arrow disappearing from the screen, the popup would still show up at times. Some found workarounds by clearing cache, logging out, or using a "Follower" link to get back to the Demonbusters page.
  • On Oct 30th, around 9:30 PM (EST) the site experienced 403 and 404 issues. Reloading the page would cause it to display correctly, but this lasted to about midnight for some.

>admin: ReportsEdit

  • Oct 28

We released our Halloween event to a portion of the Gaian population this morning, but due to some unexpected server freak-outs we've had to put it on pause for the time being. If you already got a chance to play, don't worry—you won't lose any of your items or progress. We'll make another attempt to re-launch it tomorrow, and hopefully things will go a little more smoothly.

There's still some fun to be had, though. We've released the Demonbusters manga, so you can catch up on the strange events leading to Halloween.

Sorry for the false start, and thanks so much for your patience.

-The Gaia Team

Glitches: Gaia TownsEdit

  • Jack in towns was not functioning properly, and when a user had collected 100 candies, Jack would take the candy but not give the user their Jack themed items. (This was later fixed, though more than 24 hours later).
  • Flash errors would occur and send up multiple "Quit" or "Continue" popups.

Dev AlertsEdit

10/20/2009 1:26 PM - We accidentally added an extra '0' to the Gcash cost of followers. This has been fixed. 10/28/2009 1:32 - We are currently rebalancing some missions. 10/30/2009 12:09 - Firing should be working correctly. Developers messing around too much in the database. 11/03/2009 11:22 - Missions are not frozen, game is now more balanced, and we have addressed the firing issues.


  • With the arrival of B.O.O. and S.I.N., there were early speculations on their involvement of this event.
  • A worm and its humble existence was the start of the demigods fighting. They argued over how the worm would be better suited based on their own personal preferences.
  • As soon as B.O.O. and S.I.N. arrived, two guilds were created, both User-run. These Guilds invited people who B.O.O. and S.I.N. accepted as Friends. A mere few days after, another guild was created, calling itself N.U.B. and establishing itself as Neutral. This Guild invited people from both factions.
