A Misfit turned Freedom fighter turned general turned politician, Sean Napier is perhaps the most dynamic character of the series. We first meet him shortly before the second Neo-sapian war. At that time, Napier was Security force member in Chicago, though it's implied that prior to this he was a hot shot Exo-fleet pilot with a record of insubordination and an attitude toward authority and it was these traits that ultimately got Napier kicked out of the Exo-fleet.
