10 DC Comics Heroes Who Still Need To Appear In The Arrowverse
5. Power Girl
Which Show? Supergirl
Melissa Benoist has done such a terrific job as Kara Zor-El over the past two seasons of Supergirl that it's enough to make you forget that many fans' preferred version of the character is actually Power Girl, a doppelganger of Superman's cousin from a different universe.
Unfortunately most known for the "boob window" in her costume, Karen Starr is a great character with a very different personality from Supergirl. While Kara tends to be depicted as younger and less experienced, Karen is more mature, confident and a more aggressive fighter.
It would surely be a brilliant match to see Kara encounter an alternate version of herself. Upcoming animated webseries Freedom Fighters: The Ray is already introducing the idea of alt-Supergirls with its inclusion of the evil Overgirl. Exec producer Andrew Kreisberg has also chatted about the possibility of meeting the Earth-1 Kara before.
They could get Benoist to play both parts - or maybe even cast Laura Vandervoort (who previously played Supergirl on Smallville).
