Best: Supergirl
Supergirl is Superman’s cousin and she is also pretty powerful. Her powers include: unlimited superhuman strength, speed, stamina, invulnerability, flight, super breath, x-ray vision, telescopic and microscopic vision, freeze breath, heat vision and super hearing. Since 2015, there has been a wildly popular “Supergirl” show on the CW so perhaps there’s a movie in her future!
