Supergirl

What would a list of powerful comic book characters be without a Kryptonian? And what would a list of the most powerful superheroines be without Supergirl? She’s Superman’s cousin, and she’s even more powerful than he is. However, her lack of experience usually ranks her below Kal-El.

Kara Zor-El has all the powers and abilities of a Kryptonian under a yellow sun, including super speed (flying or running), invulnerability, super strength, X-ray vision, a superior healing factor, super intellect, and so on.

We assume she’s stronger than Superman because she doesn’t restrain herself, a personality trait that makes her more powerful, although it’s also a vulnerability.

Supergirl has appeared both in movies and on television. Most interestingly, Zack Snyder left a Man of Steel Easter egg that led us to believe that we’ll see her on the big screen again.
