Who is Jack Power?
Origin Jack Power is the son and third child of Margaret Power and James Power , an inventor who once made a device which (unbeknown to him) could destroy large parts of the universe. The alien race known as the Snarks came looking for the device and thus came into conflict with the Power kids, whom moments before had received amazing powers from Whitey, an alien who died trying to warn the Power family of the nearing danger of the Snarks. Jack was given the power of body density, which meant turning into cloud-form, and shrinking to small sizes, while his density stayed the same. His siblings also gained super powers: Alex could control gravity, Julie could fly and Katie could disintegrate matter and then fire energy balls. Jack adopted the code-name Mass-Master. Although they four of them now had amazing powers, they could not stop the Snarks from kidnapping their parents and taking them of into space for further study of the humans. All seemed lost until the smart-ship (named Friday) of the now dead alien Whitey told the Power kids he could follow the Snarks and try helping them rescue their parents. The foursome went of to outer space, in hot pursuit of the Snarks.
