These are original Assassin's Creed characters, and only four of them. I've created them based on events happening in the time period I picked. This is not meant to be the next Assassin's Creed game, though it would be amazing if Ubisoft used these characters and ideas. This is in the rough stages of design for story and fan fiction so if the plot seems underdeveloped that is why. Figuring out who died during the American Mexican War is sort of difficult for me to figure out at the moment. These characters would also span about two games and two stories rather then just one. Thank you for reading.
Preferred to be called by his last name of Anderson, or Mr. Anderson, though his first name is Erik. Young and brash, Anderson prefers to be more of a swashbuckler then anything, not really being all that good at sneaking or using daggers or poison, but his skill with swords and guns is pretty great. The Creed sends him down towards Texas and Mexico knowing James K. Polk, who sides with the Templars, plans on enslaving Mexico all the way to the West where California resides. There he finds a slave and rescues him. Anderson, who likes the idea that he is far greater then he actually is, takes the slave in as an Assassin and trains him. After taking out Templars like Stephen W. Kearny and getting them out of both California and Mexico, Anderson is appointed to building up a Creed in California. Possible inspiration to Zorro.
Escaping his bonds as a slave, Cornelius tried to head North, but was pushed South instead. While he made great headway and ended up in Southern Texas, he was eventually rounded up by a posse. Luckily for him, Anderson was just passing by and ended up saving his life. Taking the name Cornelius, the slave proves valuable as while Anderson wasn't the sneakiest person alive, Cornelius was more of the poison using, sneaking quietly, cautious type to keep Anderson in line when need be, and as part of the Creed Anderson sees Cornelius as somewhat of an equal, more master and apprentice then white and black. After the American-Mexican war, Cornelius is sent East while Anderson is sent West. Cornelius trains under, and helps the Assassin Grand Master go into political power (Abraham Lincoln). During the Civil War, Cornelius fights against the Templar Order of the South, and ends up on the bad side of Templar Grand Master John Wilkes Booth. While Anderson would be the star of the first game, Cornelius would be the star of the second.
The bastard son of David Crockett, Danny is a hunter and an ingenious weapon inventor. While not an assassin himself, he supports the Assassin cause, having nothing left to search for after finding his dad after the Alamo (dead). While he can hold his own in a fight, he continues to help the Assassin's from afar. He is seen in both the American-Mexican war and the Civil War.
A female Lakota Sioux Native American, Wolf as she is called by Anderson as he has trouble pronouncing her real name, is a hunter and an assassin working for the Creed, and is sent as a mentor for Anderson or to keep an eye on him so he doesn't screw up. Despite him and her clashing several times, she eventually learns to appreciate his skills and falls for his charm. She eventually moves to California with him at the end of the game. While Anderson claims to know how to write, most of the letters sent to Cornelius during the Civil War were written by her. Unlike Anderson and Cornelius, she is not playable during the American-Mexican War, and only Cornelius is playable during the Civil War.
Well there you have it, the original characters for the Assassin's Creed fanfiction me and a friend of mine are working on. Actually this is two fanfictions that could be games if Ubisoft wanted them too, one taking place in the American-Mexican War that stars both Anderson and Cornelius, and a second game that stars simply Cornelius during the Civil War. Thanks for reading everyone!
