Matthew Gideon was an Allied officer and the Captain of the Excalibur. Gideon was a man with a chequered past, known for his unorthodox and often risky approaches. Though he takes personal responsibility for the safety of all under his command, Matthew has demonstrated a willingness to take risks, not allowing diplomacy or politics obstruct or deter him from completing the mission. A trait that lead Multiversal Federation President John Sheridan to hand pick Gideon as the leader of the Excalibur's mission.
