Power mutating into a Kymellian appearance without explanation, forcing him to hide from his girlfriend Allison (who soon dates someone else) as well as from public life. The series was cancelled with issue #62. The final issue, printed in the fourth quarter of 1990 (cover-dated February 1991), depicted the team and their parents journeying into space together. One year after the original series' cancellation, creators Louise Simonson and June Brigman teamed up for the one-shot issue Power Pack Holiday Special (published in fourth quarter of 1991, with a cover date of February 1992). The one-shot comic resolved the cliffhanger the series had ended on, restored the Power Pack members' original powers, and undid some of the changes to the characters done during the run by Michael Higgins and Tom Morgan. Power Pack Holiday Special also included a short comedy story involving an art style that evoked Calvin and Hobbes, and a short story that showed an older, teenage Julie dealing with romance and self-esteem issues. The Power Pack stories were reprinted by Marvel UK beginning around 1986. It was Marvel UK's practice at the time to use a less well-known series as a secondary story in a comic devoted to more recognizable characters, and Power Pack became the back-up "strip" in a run of Marvel's licensed Star Wars weekly Return of the Jedi. During this period, it was printed partly in black and white and partly in color, as was the main Star Wars strip. Power Pack subsequently became the back-up strip for the UK ThunderCats comic, where it remained until its eventual replacement by the Galaxy Rangers series. 2000 miniseries A four-part Power Pack mini-series published in 2000 depicted the children as now being slightly older than when they had last been in the 1991 Power Pack Holiday Special. Katie was now in the fifth grade (having skipped two grades due to her intelligence), Jack had joined Julie in middle school, and Alex was now a teenager in high school. James and Maggie, the children's parents, were now aware that their children were also the heroes of Power Pack and accepted it. The Power children now wore masks when in costume and their superhero activities were largely restricted to "practice sessions" in the forest around their new home in Bainbridge Island, from Seattle. The series once again pitted the Pack against Queen Mauraud and the Snarks. Return of Power
