As a member of The Seven Guns, John Horus becomes the clear favorite to the American public. His enhancements include 360-degree perception through floating "eyes" that surround him. He is described as the strongest and most powerful of the Seven. In Issue #0, he is also the one that kills the President, Vice-President and some Cabinet members for starting and continuing what Horus believes is an illegal war in Iraq. Horus also believes the Seven Guns were directed to leave the United States on a wild goose chase so that the World Trade Center attacks of 9/11 could occur. His certainty of political conspiracy runs deep.
At this early part of the team's origin, there isn't much information on his powers. He's practically unkillable and incredibly dangerous.
