Clone Commander 4477, nicknamed Thire, was the Senior Commander of the Homeworld Security Shock Trooper legion. During Order 66, he was tasked to find Master Yoda. The Jedi escaped with Bail Organa anyways. Shortly later after Palpatine's new apprentice, Anakin, dueled Obi Wan Kenobi on Mustafar, Thire brought the badly injured Sith to Courascant for healing after Obi Wan hacked off his remaining limbs and left him to burn. Commander Thire went on to become the commander of the Courascant Guard, protecting and upholding order on Courascant He is briefly seen in Episode 3 and several works of Clone Wars. He is my favorite Clone Commander. Here's the referance link: http://starwars.wikia.com/wiki/Thire
