Power Girl is a 3-star base Power character, and often considered a gold and stronger version of Doctor Fate, having a similarly impactful power cost reduction effect that brings quick and decisive conclusion to battles.
Her shards and gear may be purchased with League Credits earned in Raids. She is the cheapest League Credits character, tied with John Stewart Green Lantern, although he is considered more specialist while Power Girl can greatly strengthen most teams. Her shards may also be dropped randomly as a raid completion reward.
Her passive does not stack with Doctor Fate's, but it does stack with Black Adam's Light Cage buff while it is active, reducing power costs by 5.
- At one point, if Power Girl pushes her opponent to the far side of the stage, she could combo her basic attacks and Super Whirl to continuously hit them without any chance of retaliation. This has since been removed.
- Power Girl's real name is Karen Starr.
- Power Girl is Supergirl's Earth-2 counterpart. However, she is more mature than Kara, as demonstrated by her costume.
