They are a group of five teenagers that reside in the South Bronx, in New York City. They were originally selected for their extraordinary abilities and aptitude by a retired Naval officer known only as Mr. Mack. He trained each of them separately from adolescence into their teen years in hand-to-hand combat, strategy, stealth, speed, endurance, and raw strength. When they were ready, he introduced them to each other. According to ancient legend, the Wolfpack has existed for at least two millennia, and serves as a cosmic balance to a group of mortal men completely devoid of compassion, love or charity, known as the Nine. The new Wolfpack soon began battling the forces of the Nine in the Bronx and continue to protect and patrol the Bronx, and battle the forces of The Nine.
