Supergirl Is the Death of Superman's Forgotten Hero.

The Death of Superman impacted the entire DC Universe, but one of the story's most unsung heroes was a radically different Supergirl.

One of the biggest comic book events in DC history is "The Death of Superman," which was launched in 1992 with the rotating team of writers and artists throughout all of DC's Superman comic book series at the time. With the Man of Steel's demise at the hands of Doomsday would send shockwaves throughout the DC Universe for months to follow, many heroes would step up to fill the void that the fallen icon had left behind. And while there would be four figures that directly attempted to carry on the legacy of Superman in their own way, the most unsung hero from the storyline was its incarnation of Supergirl.

In the immediate aftermath of Crisis on Infinite Earths, Kal-El was retconned as the only apparent survivor from his home planet's destruction, truly living up his nickname as the Last Son of Krypton. Different iterations of past Kryptonian characters, including Superboy and General Zod, were reimagined to have come from pocket universes rather than the main DC Universe's Krypton. Among the revised characters in the lead-up to "The Death of Superman" was Supergirl. Reimagined by John Byrne in 1988's Superman #16, the first post-Crisis version of Supergirl was created from a protoplasmic matrix by an incarnation of Lex Luthor from the same pocket universe as the Post-Crisis Zod, modeled after Lana Lang and Superman.
