The disaster kid, the hurriacane, small, impulsive, aggresive and reckless. Suited to be a leader? Probably not, Jack isn't the sharpest tool in the drawer, but he sure has the energy and the pack will follow him to the end of the world - and they will.

He's a dog raised by wolves, his mother was a shepherd dog, she ran away one day during a storm, came back to her human owner after a couple weeks, looking almost wild and pregnant, but humans aren't exactly kind sometimes, and facing the imposibility to take care of the pups, they abandoned the whole litter in the woods hoping for some criter to end their suffering fast enough- or maybe for some miracle to happen.
And for Jack that miracle happened, rescued by Lady, the lead huntress on their pack. She taught him to be proud and bold, to not be afraid to bare his teeth and reclaim his space in the world.
She taught him to fight, and took him among her own litter. It's not surprising that Jack grew up to be the way he is.
The way he became leader of the Reapers is, if something, quite particular. He's never been actually chosen for the role, but they all agreed he's the one that puts his face out there for them. He's intense and always burning with ideas and, even then, he counts with the advice of the whole pack for every big decision they need to take. The way they work is very dependant on their unity as a family, and the only voie they listen without argue is Keto's voice, even if she rejects the role of leader every time she's offered.
She was the one to introduce Jack to that kind of believes. The first contact he had with the idea of something bigger than them, an entity that cares for them, it gave him an explanation to many of those questions he didn't know how to answer. Someone that gives them preys to hunt, someone that makes the rain fall, to fill the rivers and the lakes they drink from. The light of the sun and the moon. Nature felt so big and overwhelming it made sense, in some way, and he holded onto those believes like a child holds to their mother's hand.

The twinned pack with Jack's, Klaus is Keto's brother and after they found eachother again, the packs are on good terms. Keto doesn't have hard feelings about her brother, maybe a little sting for those who decided she had to be taken out, but overall the packs are on good terms.

Star seekers - Buck

tba

Fanged Furies - Pyre

Other one of the very intense packs out there, met in the plain grasslands a couple times and in what comes to general terms they respect eachother as both of them are forces to take on consideration when it comes to fighting, but have clashed a lot overtime and probably will clash in the future as well.
