CT-7567

"Do the numbers 7567 mean anything to you?" "7567? I haven't heard those numbers since... why, that's my birth number!"

"Birth Number?" -Ezra and Rex, discussing Rex's designation number.

CT-7567, nicknamed Rex, was an Clone Captain that served in the Grand Army of the Republic during the Clone Wars. During that time, Rex was in charge of a military battalion known as the 501st Legion. Rex had led the 501st in battle throughout the entire Clone War in battle such as the Battle of Christophsis and the Battle of Umbara. He would continue to lead the 501st into battle up until around the time of Order 66. By that time, thanks to ARC trooper CT-5555, Rex and fellow clone commanders, CC-5576-39 and CC-3636 removed the Command Chips that would make them execute Order 66. After this, Clone Trooper Appo was promoted to Commander of the 501st legion. Around the year of 19 BBY, Order 66 was executed, but Rex did not kill his Jedi General, unlike other clone troopers, and retired himself on the planet Seelos with Wolffe and Gregor while using an old AT-TE walker as their retirement home. The clones lived their for a few years before the Ghost Crew discovered them and asked for Rex to join the rebellion, however Rex refused. He would later join the Rebellion after the Battle of Seelos and help them set up a secure base.
