Assassin's Creed AU is a fairly new AU within the Rise of the Brave Tangled Dragons fandom. In this AU, the Big Four, and other associated characters, are members of the Assassins Order, an organization from the Assassin's Creed video game franchise. This AU can be considered as a sub-scenario of Arcade AU.
About the AUEdit
Spawned from fanart, this AU takes the rich mythology of Assassin's Creed and makes the Big Four members of the Brotherhood of Assassins, an organization that wishes to encourage free will, fundamentally opposing the Templars, who wishes to save humanity from itself by taking away free will.
Because Assassin's Creed 4 takes place in a pirate-setting, fans like to consider this AU an alternative to Pirate AU. While Syndicate takes place in Victorian London, Chronicles: China in Ancient China and AC: Origins in the time of old Egypt and the rain of the last Pharaoh.
The Big FourEdit
Because Hiccup holds up a position for the betterment of mankind in a manner seen as bad to the general public, Hiccup is most commonly portrayed as an Assassin. In some circumstances, he becomes a member after he leaves Berk with Toothless after winning the chance to kill Hookfang either before or after his secret is revealed. The Dragon Eye and its lenses can be portrayed as a Piece of Eden (like the Crystal Skull), to help Hiccup find others or show him how they work and how they are made. Hiccup cold even be a friend of the Assassins as he repairs their weapons and gear with his blacksmithing skills, and sometimes studies the Pieces of Eden they find for them. While the Dragon Manual could serve as a book that contain knowledge about the pieces in place of dragons.
Jack would be a bit hesitant to join the Assassins at first, though he would help them against Pitch Black and later join their ranks. The Guardians as Assassins would have trained Jack in assassin style combat and the code they live by, as well as being the ones that convinced Jack to remain with the brotherhood.
Should Jack be portrayed as a character from the franchise, he would be portrayed as the France Assassin, Arno Dorian from AC: Unity, with Elsa as his Templar lover, Élise de la Serre. Along with the two being cast as Jacob and Evie Frye from Syndicate, for the Jelsa pairing; as the two are sometimes portrayed as siblings as well as lovers.
Because of her high value on freedom, Merida is most commonly portrayed as an Assassin. She is usually portrayed as an archer. Merida would have joined the Brotherhood for the freedom of her clan and to keep DunBroch safe from Templars that would wish harm on its people. In some circumstances, Merida would have came across the Assassins when she had ran away from Castle DunBroch in tears and later joins their ranks, when they both discovered the power within the Ring of Stones.
Rapunzel may not have the heart of a killer, but she can still help and be a member of the Brotherhood by being their healer or librarian as she digs up knowledge and information of the First Civilization and their Pieces of Eden, in which she places her findings in a journal so its contents could help future assassins. Where they are, what they do and what would happen if they fall into the wrong hands. Rapunzel could also have been trained in assassin styled combat by Cassandra, should she be needed on the field and so she could defend herself from Templars or their men.
Rapunzel would have most likely have joined the Brotherhood when she learned that Templars were planning to harm the people of Corona and that the Assassins wanted to make sure that doesn't happen; which would lead Rapunzel to help them in whatever and whenever she could. Which often has fans see her as a Assassin, as well as one of their friends. Corona's sun crest is sometimes placed in the center of the Assassin Brotherhood's emblem, while the Separatists of Saporia could serve as the Templars that Rapunzel fights, as the sect dream of Corona's fall and Saporia regaining power.
Because Pitch's actions impede the progress of mankind - spreading fear and impeding the light within others for his own personal gain - as well as holding an antagonistic position to the Big Four, Pitch is most often portrayed as a Templar, even as a high-ranking member to the Knights Templar. In other circumstances, because of his longevity, mysterious stature and his origins amongst a celestial civilization, Pitch is often seen as a malevolent member of the First Civilization.
The team are a group of modern day Assassins with their own unique stills and "toys" that they use to kill Templars, stay alive and hack into Abstergo. As well as firing up the Animus to find Pieces of Eden from the eyes of their predecessors and to awaken their assassin skills, by walking through each one of their ancestors' memories.
Heather's past and clothing in Race to the Edge makes her a revenge seeking Assassin, as she kills the Templars on the Brotherhood's list and those who wronged her adopted family and the assassin village that raised her. After falling upon her brother, she learns that she comes from a family of Templars; her birth father left her to be raised by her adopted family so she could become an assassin and undo his Templar deeds. When Dagur placed his love for his family over his loyalty to the Templars, he began to help his sister in secret.
While Heather and Dagur being a team in the later season of Race to the Edge, she and her brother can be cast as the Frye twins, Evie and Jacob from Syndicate.
The Guardians are seen as high ranking members of the Assassin Brotherhood, along with being Jack's teachers as they teach him the creed and the ways of the Brotherhood. Their G mark, crest is sometimes placed in the center of the Assassin Brotherhood's emblem. They can also be malevolent members of the First Civilization, the Relics of the Golden Age - from the Guardians of Childhood book series - can even be placed as Pieces of Eden.
Because of their clothing and goal to defend dragons from those that would wish them harm, they are seen as Assassins. With Queen Mala and Throk as two of the high ranking members of the Assassin Brotherhood and the Dragon Hunters as the Templars that they are tasked to fight and kill. Since the Wingmaidens also take care of dragons and are also part of the DreamWorks Dragons: Race to the Edge series, the female tribe could be allies of the Defender Assassins of the Wing, as fellow assassins (which could also make Atali a high ranking member of the Brotherhood), their informants or supporters in their fight.
Due to Viggo's position and view on life as a feared "business man," he and his older brother are seen as high, ranking Templars. He could even be someone that does business with the Templars and supply them with weapons, food and other items and "cargo" that they need for their cause. Should Viggo come across a Piece of Eden, he'll most likely use it to gain control of both the Assassin Brotherhood and the Templars.
Elsa is a Assassin living in the icy mountains and keeping her people safe from Templars in secret, as she can't let them know that she is on to them or risk her sister's life. She is also seen as someone that isn't aware of the Assassins or the Templars true attentions, when Anna is portrayed as a Assassin and her sister's protector. Arendelle's Crest is sometimes placed in the center of the Brotherhood's emblem.
Should Elsa be portrayed as a character from the franchise, she would be Élise de la Serre or Evie Frye, should Jack be Arno Dorian or Jacob Frye for the Jelsa pairing; as the two are sometimes portrayed as siblings as well as lovers. Fans have also portrayed her as Aveline de Grandpré, as well as a female Arno Dorian and Ratonhnhaké:ton (Connor).
Anna is mostly seen as a Assassin that joined the Brotherhood so she could protect her older sister. Mostly because she had learned that Hans and the Duke of Weselton are Templars that want to take control of Arendelle, by manipulating the Queen and killing her should she uncover their plans or when they have no longer need her "help." Anna would seek Kristoff's help in weaponry, word the Templar's crimes and providing her with "civilizing" clothes; so she can go around the kingdom unrecognizable. Arendelle's Crest is sometimes placed in the center of the Brotherhood's emblem, or is merged with it.
When the Heart of Te Fiti is portrayed or used as a Piece of Eden, Gramma Tala would get her granddaughter to seek out the Brotherhood and to keep the heart out of Templar hands. Once Moana came across their home island in the South Pacific they trained her in the ways of the Assassin Brotherhood, mostly under Maui. Once Moana becomes a Assassin, she sets out on a journey to the Mother Island so she could return the heart and to make sure that the Templars could never find the island or the heart again.
Johann is seen as a friend of the Assassin Brother, that delivers them information on Templar activities and items that he collected in his travels for them, so he could gain their trust until they uncover the Piece of Eden he seeks. Until then, he secretly tips his fellow Templars off and allows members that they could afford to lose be killed by the Assassins, so they wouldn't suspect him being a double agent or a Templar.
