Boris is one of four Tokotas that belong to a very vicious pack. He is the beta, right behind his Handler who acts as the alpha, and rightly so after fighting for it every day of his life. This does not mean he wont attempt to take over the alpha position and test his alpha's order at any chance he gets. Being the biggest of the four Tokas, and the heaviest, it is no surprise. Boris is usually kept away from other tokas outside of his pack because he is a very competitive tokota and wont hesitate to try and dominate any others around be it with violence or his growling threats. Boris was resued by his handler due to this behavior. He was set to be euthinized by his origional handler because of his disposition, but his handler came to his aid and adopted him. After his handler realized how fufilling rehabilitating a Toka felt, he set to save others, and thus Boris' pack was formed. While Boris can be hard to handle at time, and subborn in every day that ends in 'Y', he knows his handler would do anything for him, and so trusts him above all others, and will yeild to his commands- especially when offered a food insintive. The same will never be said for his packmates, however.
