Jack Power

Jack Power is the second-oldest of the four Power siblings who, as children, received superpowers from a dying alien Kymellian named Aelfyre Whitemane. Together the siblings formed Power Pack, Marvel's youngest team of independent heroes.

Bronze Age Marvel has plenty of hidden gems, and Jack Power is one worth digging for — debuting in 1984 and going on to rack up over a hundred appearances across an impressive four-decade span that stretches all the way to 2026. He's most at home in the pages of Power Pack, though his catalog footprint extends into G.I. Joe, a Real American Hero and The Transformers, giving him a wonderfully eclectic Bronze-to-modern résumé. Along the way he shares adventures with Energizer, Mass Master, Lightspeed, Gee, and even Spider-Man, keeping genuinely stellar company throughout Marvel history. With eight key-issue appearances flagged for collectors, Jack Power rewards anyone willing to follow his trail through the longboxes.
