Well, it's a sad day today. One of our beloved heroes has finally passed on. Steve Rogers, better known as Captain America, has undertaken his finally mission. Apparently, a sniper takes him down when he's leaving a courthouse.
The superhero was spawned when a scrawny arts student named Steve Rogers, ineligible for the army because of his poor health but eager to serve his country, agreed to a "Super Soldier Serum" injection. The substance made him a paragon of physical perfection, armed only with his shield, his strength, his smarts and a command of martial arts.
This ends a long run for our shield-wearing hero, who was created in 1941, but in the comic-book world, death is never really final.
