Rancor is a terrible individual. He is selfish and only motivated by the things he wants, be it attention or success. He was raised in the Arctic as a Whale hunter and, as such, prides himself in not only his swimming capabilities, but his problem-solving skills. As he struggles with and loathes his appearance, as well as rejecting his probable identity, he tends not to open up very much. A scumbag through-and-through, he is also extremely disloyal to anywolf he has not had "adequate" time to know.
*This means everyone.
