Spyboy

Spyboy is an American comic book series created by Peter David and published by Dark Horse Comics about a high school senior who is also a sleeper agent for a secretive government agency.

Plot
Alex Fleming is a regular and somewhat milquetoast high school senior whose brain hides a secret, second identity- Spyboy, a talented but emotionally cold secret agent who can be activated by showing Alex a special multi-color visual display. When Alex is in control of his body, Spyboy acts as his "subconscious" and is often able to subtly direct Alex's actions.

Over the course of the series, Alex learns that he is surrounded by undercover spies, including his own family, and the line between Alex and Spyboy becomes increasingly blurry.
