Supergirl is far more than just Superman's long-lost cousin. Sure, in full transparency, when Supergirl made her first appearance at DC Comics, that's essentially what she was.

Those days are long gone, as the modern Supergirl is wiser, more mature, and stands on her own two feet as a competent solo star. While Supergirl has respectfully distanced herself as more than just a Superman counterpart, they share many similar characteristics. For example, as much as Superman can be argued as DC's most inspirational hero, Supergirl's best lines and moments prove she is every bit as inspiring as the Man of Steel.

“There’s no cure for that. It’s called being human” Supergirl (1996) #63 by Peter David, Leonard Kirk, Robin Riggs, Gene D'Angelo, Digital Chameleon, and Bill Oakley.

As much as Kara Zor-El cannot be overlooked for her achievements as Supergirl, readers also can't forget the Silver Age human who adopted the mantle when Kara died.
