Energizer (Kate Margaret "Katie" Power), is a fictional character in Marvel Comics' universe. She first appeared in Power Pack #1 and was created by Louise Simonson and June Brigman.

Katie Power debuted as Energizer in Power Pack #1 (cover date August 1984), and used this superhero alter-ego between issues 1-25, then (after a power-swap) continued to star under the name Starstreak between issues 25-52, after which she took the name Counterweight for issues 52-62 (changing her costume in issue 47), before returning to her original codename (and costume) as Energizer in the Power Pack Holiday Special and subsequent 4-issue Power Pack miniseries published in 2000 - in the latter, she wore a different costume not previously seen. Katie did not resurface in the Marvel Universe until her appearance as a potential candidate for the Great Lakes Avengers in issue 2 of the GLA: MISASSEMBLED miniseries, where she is seen wearing her Power Pack costume from the Marvel Adventures range of Power Pack titles while operating as a solo superhero, in Loners #4, she was purportedly the recipient of a phone call from her sister Julie - though Katie was not seen during this conversation and in Fantastic Four #574, where she was among the guests for Franklin Richards' birthday party. The character has since made appearances in several of Marvel's 'alternate continuity' imprints, most notably as a recurring cast member in several Marvel Adventures and MC2 titles (see bibliography at foot of page).

Katie Power was born in Richmond, Virginia. Her full name is given as "Kate (Katie) Margret Power" in Power Pack #47. The youngest of the four Power siblings, she was only 5 years old when she was given her powers by Aelfyre Whitemane, a dying Kymellian noble. Katie and her siblings then form the superhero team Power Pack.

When she first receives her powers, Katie is highly suggestible. She is frequently goaded into using her powers by her siblings and looks to them for instructions. Consequently, she is responsible for significant damage to both buildings and some of Power Pack's enemies. Her eldest brother, unofficial team leader Alex, bullies her to such an extent that she compares him to Power Pack's archenemy, Queen Maraud. At one point, Julie observes that Katie is bullied into using her powers even when she's scared or thinks it's wrong to hurt others, and that she later regrets the damage she does. For instance, during the team's first encounter with Kurse during Secret Wars II, Katie realizes that Kurse is completely disoriented and hesitates when she is asked to blast him. After she is finally bullied into destroying a building and crushing Kurse, she immediately worries that she has killed him.
