Coal

Appearance
Coal is a black-coated wolf.

Personality
Coal is a laidback, slightly lazy, strong (but slow) wolf. He's not afraid to back down from a fight he can't win, but won't hesitate to take the challenge either. He is accepting and understanding of others' decisions, even if he doesn't like them.

Gold
Gold and Coal were close friends as Coal rarely wandered off and when he did, not very far, and he was usually following Sol. Gold didn't have to worry about Coal as much as his littermates, so she was grateful for the break that gave her.

Cloud
Cloud sometimes gave Coal extra food for being such a good pup, and also since he was the runt of the litter and a lot smaller than his littermates. Coal loved this, (obviously), and so they both got along great with one another.

Sol
Coal and Sol often argued, but still were as close as brothers could be. Coal normally said that they shouldn't leave the den as they may get eaten by a coyote or something, but followed him anyways. Despite this, he didn't seem to notice when Sol was being tailed by a coyote.

Copper
Copper never had a close bond with the laziest of her siblings, but still play-tackled him and didn't treat him any differently than her other siblings other than not hanging out with him as often. After Slate and Sol's death Copper's bond with him almost vanished completely, only surviving on a tiny thread of bloodline.

Slate
Coal usually followed Sol, but sometimes Slate would drag him away to follow her. Sometimes he would be able to slip back to the den before he got in trouble with Gold and Cloud, and occasionally even told on her, earning him the nickname of "taddle-tail" by Slate and Copper.

Midnight
Coal and Midnight bonded quickly. Coal was frantic to find her when separated from her even only after knowing her for a few days, although he was accepting - but sad - when she took her place at the head of the Rosebud Pack and didn't leave. After Rose's death, however, Midnight offered to go with Coal again. She was sad - but accepting - when he said he still needed time to grieve. However, when Coal rushed to find her, she quickly agreed to go with him.

Rose
Rose wasn't ready to let Coal go after Midnight decided to stay with her new small pack. Coal and her steadily became friends. Coal and her bonded quickly. Coal was heartbroken at her death and even turned down his former potential mate while he was still grieving.

Jasper
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.

Twilight
Coal enjoyed watching Twilight, but Twilight never really noticed, too busy trying to beat Ruby in their play-fights.

Ruby
Coal seemed to pay extra attention to Ruby, always laughing and warmed by what she was doing, and enjoyed spending time with his daughter. Whenever she wanted to play, he would usually play back, and try to avoid picking her up when she had a stick in her mouth. He also liked looking at the sticks that were littered around the den that she used to play with.

Citrine (2.0)
Coal never paid attention to or noticed Citrine. He was well-behaved, never wandered off much, and in general not a pup he had to worry about, which he appreciated despite never showing it.
