Every Arrowverse hero ranked from weakest to strongest

Supergirl

You really shouldn't be surprised to see Supergirl at the top of this list. She is, after all, a Kryptonian hero, and very little in DC Comics can match the strength and power of a Kryptonian. The Girl of Steel went on an incredible journey throughout her time in the Arrowverse, evolving from a shy and frightened young woman afraid to use her powers into Earth's mightiest hero. And yes, we mean it's mightiest hero, as the season 2 finale revealed that she was even more powerful than her Earth's Superman.

Supergirl has all the abilities you could ever want if you were a superhero; she can fly, she's incredibly durable, and she has super strength, super hearing, and super speed. Kara Zor-El can also attack her enemies from a distance, unleashing heat vision, ice breath, and even X-ray vision to find them when they're hiding.

When Supergirl concluded, Kara Danvers' journey of growth was evident. She had quite literally accomplished it all, and she was ready to tackle a new journey because of that. Perhaps her journey was the most fulfilling of them all, because she had inspired so many people and then she found a way to inspire them all over again. Perfection.

A powerhouse in every sense of the word, Supergirl quite literally had it all.
