Not much is known about the history of this incarnation of Katie Power/Energizer. She is the second daughter and youngest child of James Power and Margaret Craigh. In Hulk and Power Pack Vol 1 2, it's stated she is 8 years old, which means she was 7 years old when she received her powers from Aelfyre Whitemane (which happend over a year earlier, according to Power Pack: Day One Vol 1). This makes Katie at the moment 3 years older than her Earth-616 counterpart was upon receiving her powers.

Despite this age-up, she is still one of the youngest superheroes ever, and the one who most often acts like her age. She is very fond of her stuffed toys, saturday morning cartoons (especially Spongebob), and ponies, accidently mistaking Beta Ray Bill for one when she and her siblings visited Asgard. She hates robots however.

She was at one point possessed by the Venom symbiote, and under his influence teamed up with the Sinister Six against Spider-Man.


Seemingly those of Katherine Power (Earth-616)#Powers. So far, she has only demonstrated the energy powers identical to those originally bestowed upon her Earth-616 counterpart. It is unknown if she ever switched powers with her siblings like her Earth-616 counterpart did.
