Before Steve Rogers looked the part of Captain America, he was just a scrappy kid from Brooklyn. But thanks to his can-do attitude and drive to do the right thing, he was picked for a super soldier initiative.
As the experiment gets underway, it looks as though Rogersâ€™ frail physique is going to succumb to the treatmentâ€™s demands. But Rogers refuses to give up, and once the experiment is over, he comes out looking taller and more muscular.
Any doofus with half a brain couldâ€™ve underwent the procedure. But it was Rogersâ€™ heroic personality that made him Captain America, even before becoming a super soldier.
Even though he was scrawny and physically inferior to other super soldier candidates, Steve Rogers possessed something the others lacked: heart.
During a routine drill during training camp, Colonel Phillips (Tommy Lee Jones) throws a dummy grenade into a crowd. While everyone runs away in fear, Rogers jumps onto the grenade in an attempt to protect those around him.
It was a brave and selfless act, one that once and for all proved that Rogers was destined for greatness.
