Demon of Justice is crossover between Mobile Suit Gundam Wing and Oath of Swords. It is a notable piece of fanfiction that predates both TV TropesandFan Fiction Net. Due to real life issues work on it stopped sometime in 2005/2006. As of Mar. 4th, 2013 it has been updated to Chapter 41.In a battle with Oz forces Chang Wufei strikes an experimental enemy weapon at just the right moment, any earlier or later and he would have died. As it is the weapon, which accessed power from the fabric between worlds, did explode, and shove Wufei and Nataku through the fabric of reality. Before Wufei could go mad in the nothingness between realities he is summoned; as a demon.In Orfressa, where two factions of gods have been at war for millennia, things aren't going well for the good guys. The continent of Kontovar fell to the Dark and had to be wiped clean by a wizardly Kill Sat, but the biggest victory Phrobus pulled off is one no one remembers. Without the Light Gods of War & Death, the others are trying to pick up the slack, but there are far more demon summoners and undead about.Wufei now has to deal with this new, medieval, world. Learning languages, non humans, gods, a new link to his Gundam, and a Godly Stalker. His friends back home have to adapt to life without him, a new peace, and the fact that their friendship is one that will never break.Original archive is here. Another archive can be found here. Updates will eventually appear there. For now new updates are found on Live JournalPage is a serious work in progress.
Tropes included are:
Action Girl - Naiya. She's a Horse Stealer Hradani, one of the few tribes that teach their women to fight. She's probably about as tall as an average human man and supernatural stamina and strength. While she hasn't really 'fought' yet, she has looted the dead bodies of her kidnappers and tried to charge towards where an angry dark war god was because Wufei might need her.
"Defaulting on rent gets you evicted, you see, but tax evasion is treason. If you plead poverty, and they're feeling lenient, they just evict you, confiscate all your property, and put a lien on your future wages. If they're not feeling lenient, well... treason is a capital crime.".
Bigger Bad: most of Sharna's siblings and his parents, notably Phrobus.
Boogie Knights: Mentioned. Duo left Wufei some dance music for his Gundam. Not even Wufei knows why a gundam would need dance music, and seems to be slightly afraid along with being mostly bemused.
Breaking the Fellowship: Happens in the prologue, and is partially subverted. Wufei is having trouble in the new world, meanwhile back home, with the exception of a busted knee and some angst, things are going Very well.
Combat Tentacles: An amorphous demon forms them with fanged mouths on the tips. Considering they get under Nataku's armor in the leg region, this might count as a really really strange example of Naughty Tentacles.
Death by Adaptation: Bahzell himself, the main hero of the War Gods series. The authors like him, but couldn't keep him alive without him taking over the plot. So he dies after his final battle against Harnak.
Destructive Saviour: Hard to avoid when one of the fighters is a giant robot in the fields of a medieval village, and the enemy is a amorphous screaming blob.
Doomed by Canon - Averted for Yithar, who was killed by Bazhell shortly after his introduction in canon. Sadly. Averted in Chapter 32.
Dying Moment of Awesome: Wufei knew full well he might die taking out the cannon. The amount of destruction the exploding cannon causes, however, is credited as to why OZ surrendered. Fortunately for the story, he didn't die.
"Well, I know Wufei's not in love with me," Rami said frankly. "And, well, he is very handsome, in a scary demonic sort of way, but... I can't imagine him settling down and having children in a comfortable little cottage, doing repairs and things. I want the cottage and the children and the sort of husband who'll fit in there, so there was no point falling in love with him." She smiled up at Naiya. "It was fun pretending, though. Just like a ballad!"
Rebel Prince - Wufei did not want to pilot Nataku, he much rather have been a scholar, or rather...
Mooks - There are plenty of nameless evil minions in the Forces Of Evil, but it's not uncommon in Mel and Christy's words for for some of them to get a name and a line of characterization. Even if it's right before they get their throat sliced open.
Nominal Importance - Averted occasionally. One of the authors advocates changing names in a baby name book, the other angsts over it and won't do something so unimportant. However at least one character has been killed in the same scene that he's been named.
Our Demons Are Different - Any being from another dimension under a certain power level qualifies as a demon, even a bunny. Discussed Trope - characters wonder if such a bunny would become Killer Rabbit.
Polar Opposite Twins - Krashnark & Sharna are identical twins. Within the Dark Pantheon Krashnark is second to only his Father in power, he is personally courageous and honorable. Sharna is a stupid mewling coward and substantially weaker than Krashnark.
Poor Communication Kills: Averted. How do you explain gods and demons and revenge to someone who doesn't speak your language? "Sharna's people fight."
Refusal of the Call - All champions do this at first, so presumably Wufei's initial refusal isn't that unusual, especially for a Dark God that prefers decent people.
However, the person who tells us all champions do this at first is a Light God and only speaks of his own champions. Given that champions have to be somewhat similar to their Gods and the God chooses which of the people with potential become champions, it may only be His champions who hold themselves to such high ideals that they object on the grounds they are unworthy.
Ripple-Effect-Proof Memory - Played with. Some characters are aware that they are missing something. Phrobus is cited as the reason why the number 7 is unlucky in Orfressa, though he is the fifth child now.
