No, she has her own troubles.

Power Girl sees Supergirl having trouble in battle, but has other stuff to deal with.

Giganta has somehow gotten stronger and faster while in Prison, making her far less of a pushover than their last encounter. Her giant hand proves to be quite adept...

Power Girl manages to get her hands up to stop it from squeezing down on her, but it still smashes her backwards through a Building!

Struggling to keep the fingers from pressing down, the Superheroine is easy pickings for an opportunistic Villain.

The Gentleman Ghost bided his time, but now floats into the action! He whips out the sword from its cane covering and slashes at Power Girl's back.

He's surprised to see that her invulnerability partially-blocked the effect. Just like with Kryptonite, Power Girl's unique DNA gives her a slight advantage over her 'sister.'

Seeing that his sword cuts the cloth, however, the Ghost decides to have some fun.

He lets loose a series of quick slashes at the Heroine's back as she continues to struggle. She feels the sting, but doesn't yet realize the added effect.

The Ghost floats back to admire his work, catching the girl's golden belt as it falls.

"Would Superman send you out if he knew that you liked to fight crime naked," the creepy Ghost asks.

Power Girl looks down and sees that he's right- about the naked part, that is. She starts to panic, forgetting her training.

Giganta takes advantage and closes her hand, the **** knocking out the heroine temporarily. She lets go...
