When it came to Superman’s origin story, James Gunn mostly played it safe in his 2025 movie. While the plot zooms past Kal-El’s birth on Krypton, his arrival on Earth, and his wholesome Kansas upbringing, none of those details change much. They still define the character as an all-powerful alien who represents the best of humanity. But Gunn did make one radical change to the Superman origin story, and it’s one that Supergirl smartly doubles down on.

It’s great to see that Supergirl is maintaining some continuity in Superman’s story. Fans often appreciate when beloved characters are treated with care, especially regarding their origins. Looking forward to seeing how this unfolds!
