Jack Power

Jack Power, also known as Mass Master, and formerly as Counterweight and Destroyer, is a fictional character appearing in American comic books published by Marvel Comics. He first appeared in Power Pack #1 and was created by Louise Simonson and June Brigman. Publication history Jack was a founding member of the superhero team Power Pack. The second youngest of the four Power siblings, he was years old when he was given his powers by Aelfyre Whitemane, a dying Kymellian noble. He continued to operate with Power Pack through their entire history. Fictional character biography Jack Power was born in Richmond, Virginia. Brash and ornery, Jack was the "wild child" of the Power siblings. He frequently insulted and argued with both his teammates and his adversaries. Queen Maraud, Power Pack's archenemy, feared him more than the other children because she thought he would be the most likely to take advantage of the lethal nature of his powers. However, his bold nature also made him a key fighter for the team. He possessed a tremendous amount of loyalty and courage, and usually kept a cool head even during stressful situations. Jack jumped into the East River to help his sister Katie escape from an ocean liner. He even taunted the Snark Jakal who was about to kill him with "Can't even kill someone until Mommy tells you to?!".
