Mountain was the first wolf in Leaf's pack and immediately appointed to Beta. He is the best hunter in the pack.
He has no love interest, nor does he wish to with anyone. However, Leaf and Mountain decided, for the good of the pack, to have pups with either her or any other female in the pack to keep their legacy going. He doesn't mind really. Of course he will love his new pups like any father would.
He is generally a bully sometimes to others, especially when orders are being given. The only reason for this is not to be mean, but because he sees potential in his pack members and wants them to do well in their duties. Others see him as... unfriendly really. but deep down, he does love his pack. the only reason for his harsh words and "leave me alone" attitude is his former pack treated him very poorly, so he feels deep down it may happen again, and doesn't let anyone get too close to him in fear of loosing them too quickly.
