Jasper

Jasper is Coal and Midnight's pup.

Appearance
Jasper's coat changed from dark brown to black (going back and forth) during pup hood, but changed into a beautiful mostly black coat with white spots as an adult.

Personality
Jasper is a bit of a wanderer and always preferred to stay to himself rather than play with his siblings. He usually was fast to get into the den and one of the most watchful and cautious wolves.

Coal
Coal was always dragging Jasper back to the den, forcing him to spend time with his siblings and family. Although Jasper appreciated Coal, he was Jasper's least favorite parent as Coal didn't understand Jasper's lonesome tendencies.

Midnight
Jasper made an effort to socialize with Midnight when she was close enough to the den since she understood his loner trait and wandering habits.

Twilight
Jasper and Twilight never interacted much, although Twilight did try to follow Jasper a few times when he wandered away and tried to wander off herself a few times in an effort to see the world and get Jasper to relate to her more.

Ruby
Because Jasper usually distanced himself from his siblings, Ruby's playful tackles only went one way. However, Jasper only felt a sort of kinship to his sister when she wandered away from Twilight and Citrine to lay behind the big rock.

Citrine (2.0)
Jasper never made an effort to hang out with Citrine, and Citrine never made an effort to hang out with Jasper. They'd lay together and found comfort in one another during attacks from wolves, eagles, and coyotes, but never shared an obvious bond.

Trivia

 * Jasper was the only one attacked on the journey to the Rendezvous Site.
 * Jasper was the only wolf in his litter to not get something (bruises, scars, radio collar, etc.) in the gap from puphood to adulthood.
