Adorkable Major Bighorn is a character in the "Adorkable History" series.
Major Bighorn first appears meeting Chief Major Clop as his regiment moves in on the territorial lands of the Bison tribe. He tells the chief that Celestia thinks their land is truly beautiful and mentions that more travelers of his kind will be coming through. He then says that he will be using the tribes burial grounds for their new fort, and that he will trade them sickness for their women.
As time goes on, Major Bighorn informs Chief Major Clop that he will be moved to a new territory just for him and his kind. Chief Major Clop, feeling betrayed says, "You turn your word on me, I turn my back on you." Angered by the response, Major Bighorn has the chief shot in the back by his sergeant.
Major Bighorn seems very proud of Equestria and feels superior to the Bison race. This is shown by how he often interacts with Chief Major Clop. He seems to fully take to heart that Equestria must be united at any cost, as said by their leader, Celestia.
