| Character Identity |Katherine Margaret "Katie" Power / Energizer
| Age |10 years
| Character Differences |This is what it says on the tin. For the sake of consistency, the events of the 2000 mini-series are excluded. Instead, this character history represents
Power Pack (vol 1) #1 through #84, associated tie-ins (X-Men, X-Factor, Fantastic Four) as well as the Holiday Special, but diverges at that point.
| Brief World Background |No reinvention here. A universe closely matching that of the mainstream or 616 Marvel universe, with the exception of the events of the 2000 Power Pack mini-series. Power Pack, reviled by the public for the common belief that they were mutants, battled Kurse alongside the Avengers, Apocalypse alongside X-Factor, faced Inferno alongside the New Mutants, as well as minor adventures with Cloak and Dagger, as well as the Punisher.
| Brief Character Background |Most 10 year old girls are not four years into a superhero career. Katie Power is not most 10 year olds. At the age of six, she fell victim to an alien attack on her family's home when the Zy'nx arrived to kidnap her scientist father. A Kymellian observed the invasion and was compelled to intervene to save the girl's life, becoming mortally wounded in the process. Passing a measure of his power to Katie and her three siblings, the Kymellian urged to children to save their parents as he died, leaving Katie in possession of destructive energy powers.
After the successful rescue of their parents and the defeat of the Zy'nx (Snarks, as the children called them), the siblings formed the superhero team Power Pack. Often mistaken for mutants, as Power Pack they would wrestle with otherworldly demons, fight alongside the Avengers, witness the massacre of the Morlocks, and face the Four Horsemen of Apocalypse in addition to coping with growing up, maintaining their identities apart from their parents or teacher's notice, and dealing with regular lives as school children. Katie, in particular, was shaped as a child by a defining moment where she had to choose between using her powers against Famine or intervening to save the life of Jean Grey. Katie made her choice, which resulted in the death of Famine. This experience made Katie, the youngest member of Power Pack, the most conscious of the consequences of their powers and actions.
After several adventures as Power Pack and the subsequent sharing of their identities as such with their parents, the children adventure less in an effort to have a more normal life. Alex, her eldest brother, went on to be part of both the New Warriors and Future Foundation. Julie, the second oldest, became disenfranchised and joined a support group known as Excelsior. Jack remained friends with Franklin Richard, while Katie would sometimes embark on solo outings. This caused her to receive a recruitment offer from the prospective Great Lakes Avengers, though she ultimately turned it down.
When a call for help came out from the Future Foundation, Power Pack answered the call. Their first outing as a team in years. When that mission had finished, however, the children had once more gone their different ways in life, with only Jack noticing when Katie just went
missing one day.
Teleported to an alien world, Katie found herself used for some sort of gladiatorial entertainment, pitted in life or death battles where her destructive powers would be on full display despite her gentle nature. Most often, this takes the form of the battle triggering her body's limit and the resulting explosion providing a fireworks finale that is as dazzling as it is deadly.
| Notes |- As an energy-based character, Katie's power is very physics based (like the rest of Power Pack, being divided into gravity, density, velocity, and energy manipulation power sets). She generates energy by disintegrating and breaking down matter, with the freed atomic bonds being the source of her energy. This means she derives more energy from solid matter than she does gas. This can include the ground beneath her when she's not mindful about controlling her powers and can inflict horrific burns on an opponent similar to contact with an acid. Similar to the character of Bishop, she can also absorb directed energy strikes, though this will trigger her body limitation (
see note below) more rapidly than through the disintegration method.
- Her ability to store energy in her body is finite and becomes physically painful for her as it scales, until she explodes like a bomb.
- As in canon, Katie's costume exists in an alternate dimension known as
Elsewhere, where it is maintained by beings known as the Elsewhere Tailors. The pockets serve as a mechanism for passing correspondence to the tailors, allowing Katie to request changes or alterations to the costume.
- The words "costume on" summon the suit from Elsewhere, while anything she is wearing is teleported to Elsewhere. The tailors have been known to launder and repair the clothes.
