You don't even need to follow comics closely to know all is not right with Captain America. The stalwart hero of Americanism betrayed his allies in the Marvel Universe in a twist at the end of Captain America: Steve Rogers #1 by revealing himself to be a secret agent of Hydra. While it was revealed that this was caused by the Red Skull using a sentient Cosmic Cube known as Kobik to re-write Cap's reality to be a Hydra loyalist from childhood, the fact remains that Cap is now the leader of an evil terrorist group that flies in the face of everything he stands for, something that hasn't been sitting well with some fans.
