Michael Scofield
At the end of Season 3 Sucre was incarcerated into Sona for refusing to reveal to the guards the whereabouts of Michael Scofield subsequent to his escape. T-Bag convinced them that Sucre was involved, and after being tortured for several hours he was thrown into Sona, just in time to see T-Bag take over as the new ruler of the Panamanian prison after the death of its former ruler, Lechero.
