Supergirl Upgrades a Superman Power After 48 Years of Movie Appearances

Superman’s heat vision, a power first hinted at in a 1939 comic book, has evolved significantly over the years. Initially, it wasn’t a separate ability, but rather an extension of his x-ray vision – he could melt things by maximizing that power. However, it quickly became its own distinct ability. Now, almost 50 years after Christopher Reeve famously displayed heat vision in the movies, the power is being reimagined again, thanks to the TV show Supergirl.
