We've all heard of the death of Captain America. In Captain America #25 it seemed like the original Cap, Steve Rogers, was shot by a sniper and then finished off by his brainwashed girlfriend Sharon Carter. This was all portrayed as part of the Skull's devious plan to manipulate the American political landscape and get a candidate loyal to the Skull to win a presidential election.
In the current Captain America: Reborn mini-series it seems that the Red Skull's plot to kill Captain America was actually much more sinister. After the Skull was murdered by Aleksander Lukin, the ruthless head of the Krona corporation, the Skull's mind was trapped in Lukin's body via the use of a Cosmic Cube (only in comics folks). Once in this position, the Red Skull began scheming to get his mind out of an unacceptable vessel (old Russian man) and into an acceptable one (hunky Steve Rogers). That's all derailed by the intervention of Bucky, Falcon, Black Widow, and Sharon Carter.
