Assassin's Creed AU

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.

About the AU
Spawned from 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, fundementally opposing the Templars, who wishes to save humanity from itself by taking away free will.

Fans like to compare the Pieces of Eden, ancient technology with various ancient uses that appear as holy artifacts to humans, to the Relics of the Golden Age from Guardians of Childhood.

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 and Chronicles: China in Ancient China.

Hiccup Horrendous Haddock III
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 are made.

He can also be cast as Ratonhnhaké:ton (Connor) from ACIII. While Astrid plays Aveline de Grandpré from ACIII: Liberation.

Jack Frost
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.

Jack can also play the France Assassin, Arno Dorian from AC: Unity, with Elsa as his Templar lover, Élise de la Serre.

Merida DunBroch
Because of her high value on freedom, Merida is most commonly portrayed as an Assassin. She is usually portrayed as an archer.

Rapunzel Corona
Rapunzel way not have the heart of a killer, but she can still help the brotherhood by being their healer or dig up knowledge and information of the First Civilization and their Pieces of Eden. Where they are, what they do and what would happen if they fall into the wrong hands.

Pitch Black
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.

Big Hero 6
The team are a gang of modern day assassins (from Japan) with their own unique stills and 'toys' that they use to kill Templars, stay alive and hack into Abstergo. They also fire up the Animus to find Pieces of Eden from the eyes of their predecessors.

Heather
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 village.
