History
Kate Power was originally known as Energizer, the youngest member of Power Pack, a team of pre-teen superheroes made up of herself and her three siblings who gained their powers from a Kymellian named Aelfyre Whitemane. Her history largely mirrors that of her Earth-616 counterpart, except that in this reality these adventures happened 15 years earlier.
Kate Power is called upon by Frank Richards to assist the Avengers in locating the missing Thunderstrike.[1]
