50 Reasons Why Superman is The Greatest Superhero Ever
20. When He Died, He Left A Giant Void
Much of the story lines after the Death of Superman in the attempt to bring down Doomsday revolved around the world trying to find a way to fill the void left by Superman after his passing. Many teams and vigilantes popped up prepared to fill Superman's shoes and there was even a storyline involving four uber-men who may or may not have been Superman. Is Superman half cyborg? Is he the young guy with the shades? Is he the mystical guy with the shades? Or is he the African American guy in the steel suit? There's even a heartbreaking storyline involving Superman fan boy Bibbo donning the Superman shirt and fighting crime for him. In one scene after someone dumps a bag of puppies in to the ocean, he dives in after them and saves their lives, prepared to house and adopt them all.
19. He's The Basis For A Charity
Superman became one of the major symbols for the Christopher Reeve Spinal Cord Injury and Paralysis Foundation, which helped to promote the research in spinal disabilities and help to cure and repair patients who suffered from the same crippling injury Christopher Reeve did before his unfortunate death. Superman's symbol was used during the marketing and to help spread word for the promotion and dog tags are still sold in the website's store with Superman's symbol emblazoned on them. We miss you, Chris.
18. He Was The Basis For Two Hit TV Shows
Granted the show was pretty awful, and I tapped out after season four, but "Smallville" was loosely based on the adventures of young Clark Kent before he became Superman. The series lasted ten seasons and is still one of the longest running Superman based shows ever created. It's also influenced many networks to attempt the same formula time and time again.
There was also The Adventures of Lois & Clark starring Dean Cain and Teri Hatcher that ran forever in the 90's.
