“Supergirl: Woman of Tomorrow”
Based on King’s comics run of the same title from 2021 and 2022, “Woman of Tomorrow” features Superman’s cousin, Kara Zor-El, who, as Gunn explained, “is a very different type of Supergirl.”
“We see the difference between Superman, who was sent to Earth and raised by loving parents from the time he’s an infant, versus Supergirl, who was raised on a rock chip off of Krypton, and watched everyone around her die and be killed in terrible ways for the first 14 years of her life.”
Gunn called this Supergirl “much more hardcore” — though King’s series also involves Krypto, the superdog.
