Pack (canine)
Animals which typically predominate over others are associated with the term "alpha". Among pack-living wolves, alpha wolves are the genetic parents of most cubs in the pack. Such access to mating females creates strong selective pressure for intra-sex competition.
Silver Sable
The Ultimate Marvel iteration of Silver Sable is the mercenary leader of the Wild Pack. A mercenary from Symkaria, she had a troubled childhood, apparently ignored by her father and abused by her alcoholic mother. In reality, her father hunted Nazis and she forgave him at his deathbed, deciding to follow his footsteps. While an antagonist to Spider-Man, she is not actually a villain so much as a bounty hunter, and she holds no particular ill-will towards Spider-Man.
