Part of a very special holiday tradition that may have made the single largest impact on the western Hetalia fandom in a matter of several days due to the large fanbase and live updates, the 2010 event lasted a grand total of five days and has spawned a Fountain of Memes on the LiveJournal community, until finally receiving its very own page here on TV Tropes.Finland hosts a live stream of the Christmas season in the world of Hetalia, answering fanís questions and requests until a mysterious shadow looms over the broadcast. Suddenly, nations begin disappearing one by one and the remaining characters gather together in an attempt to solve the mystery and find the culprit.You can read the scanlations here.For the 2011 Bloodbath, click here.Also has its own Memetic Mutation page.
This event provides examples of:
Alcohol Hic: Turkey does this a few times after getting drunk.
Ascended Extra: Quite a number of minor characters appear during this event and become a major part of the unravelling storyline, including the Nordics, Cuba, Belgium, Hong Kong, Cameroon, Osaka, Monaco, and a cameo by Bulgaria.
Iceland worrying about the rest of the Nordics, to the point of collapsing.
Russia crying at General Winter's defeat and General Winter gently touching the sleeping Russia's cheek.
In general, the amount of care and concern between nations as others are attacked. Poland warning Lithuania and waiting by him as he sleeps, Germany and Hungary's reaction to Prussia's kidnapping, Osaka trying to aid Japan even though he's useless etc. And keep in mind that some of these nations don't actually like each other but are willing to set their grievances aside should the need arise.
When everyone finally finds out what's going on from Sealand, the entire world bands together and cooperates to help save the Parallel!world. World peace, brought about to help a bunch of total strangers.
Evil Phone: At one point during the broadcast, everyone's phones begin ringing for no reason. Turns out it was Russia who has hijacked the Nordics' communication signals.
Failed a Spot Check: Belgium and Spain (at first) have no idea the shadow that appeared before them is dangerous at all. Belgium even gives her attacker the scarf that she had bought, subduing him at the same time.
Kidnapped Mid Sentence: Poland warning Lithuania about his bad feeling. Cue a shadowed figure looming over Lithuania when he tries to ask Poland what it was. The next panel shows his cell phone falling to the ground with a confused Poland on the other end of the line.
Similar with Prussia, who has just been saved by Germany and Hungary and about to thank them before being dragged away by his attacker.
Like Is, Like, a Comma: Hong Kong uses 'like' a lot in his speech, but not enough that it veers into Valley Girl territory. This is to illustrate that he is a teenager.
Never Split the Party: After realizing that they are in danger, the remaining nations take this course of action. Ironically in Iceland and Turkey's case, they were safer when they were apart from the main group.
Noodle Incident: The Nordics have had 6780 other meetings in random strange places.
Mainly this seems to poke fun at the early days of the fandom, back when people sincerely questioned whether nations utilized teleportation of some sort, since in some strips nations would apparently reach one another's houses in a day on foot, while in others characters like England would be seen boarding ships with humans to travel the seas for months at a time. In the end the more realistic "nations have to go through the same hassle as regular humans" won over offscreen teleportation for the most part, especially after seeing consistent use in canon.
Schedule Slip: So much that the fans have created HST (Himaruya Standard Time) to figure out when updates would occur.
To make HST even more confusing, it had gotten steadily later as the event stretched on, starting off 20-30 minutes later than JST (Japan Standard Time), then becoming 30-40 minutes, then it was 5 minutes early, and afterwards closer to an hour.
Splash of Color: As Sealand prepares to open the present he found in the cargo room, readers see an ominous shadow hovering behind him followed by Sealand's terrified expression. To make things worse, the strip in particular is colored in a deeper shade of red.
True Companions: The family that was formed between the fans on the main Livejournal community, Captalia, and even the Anon Meme is very touching.
Weather Dissonance: Because General Winter and Russia were beaten and taken by the mysterious figure, it is now summer in Russia.
Webcomic Time: Fans are watching for updates on New Years Eve when in-story it's still Christmas day.
What Did I Do Last Night?: Finland holds a meeting with the kidnapped Nordics and Estonia to figure out just what happened to them after getting knocked out by the shadow. The resulting Expo Speak only leaves them as confused as before.
Netherlands' reaction when he wakes up to find himself on the ground, clothing torn, with a similarly disheveled sleeping Spain on top of him.
When She Smiles: A lot of fans requested smiles from nations that characteristically don't smile. Belarus has a wonderful smile for exactly 0.2 seconds before she beats Finland up, and so does Latvia before he's snatched up.
Workaholic: England would rather work during Christmas instead of spending the time with Sealand. Sealand then yells at him for not giving him a present and for almost getting attacked by the mysterious figure. Of course, for the latter, England has no idea what's going on.
