Michael Scofield
The tattoo, which covers the entire upper body of Michael Scofield, is featured extensively in the first season of the show and to a lesser extent in the second season. It contributes a major part to the plot of the series, containing various details of the protagonist's plan to escape from prison and from the country. Incorporated within the tattoo are the blueprints of the prison in which the protagonists are incarcerated during the first season.
