Biography . The clone trooper designated CT - 4 / 619 was one of the many clones of the Mandalorian bounty hunter Jango Fett born on the planet Kamino . CT - 4 / 619 served as a trooper in the Galactic Republic ' s Grand Army , and fought with the Grand Army to defend the Republic against the Confederacy of Independent Systems during the Clone Wars . He participated in the Conquest of Raxus Prime in 22 BBY , after the Clone Wars opened on the barren surface of the planet Geonosis . Led by the Bothan Jedi Master Glynn - Beti , CT - 4 / 619 , along with the rest of the clone task force under her command , engaged the Sith Lord Count Dooku ' s battle droids as the clones attempted to halt Dooku ' s mission to reconfigure the Dark Reaper superweapon . On the surface of Raxus Prime , CT - 4 / 619 and a squad of troopers encountered the young bounty hunter Boba Fett amidst the ruins of Dooku ' s headquarters . Under the alias of Teff , Fett joined the group as an orphan to receive food and shelter once CT - 4 / 619 and the group had completed their mission . B2 super battle droids opened laser fire on CT - 4 / 619 and the squad , forcing them to take shelter behind an excavation rig . Including CT - 4 / 619 , the squad ' s remaining troopers had been reduced down to three , with Fett tagging along with the group . CT - 4 / 619 and the rest opened fire from the cover of the excavation rig , despite being heavily outnumbered . Another trooper fell , though Master Beti soon arrived , drawing the droids ' attention from the group to her , allowing Boba , CT - 4 / 619 and the remaining clone to open fire freely without retaliation . With the combined force of the Jedi and clones , the droids were destroyed . CT - 4 / 619 led the orphan to a LAAT / i gunship and confiscated Fett ' s blaster , which he had used to defend himself in the lightfight moments before . CT - 4 / 619 brought Fett into the cockpit of the LAAT / i , and the clone took one of the pilot seats while Fett sat on the floor . The two waited for fellow trooper CT - 5 / 501 , as he was to be the co - pilot , before taking the gunship to the " Acclamator " - class assault ship " Candaserri " , which was in orbit of Raxus Prime . Before taking off , CT - 4 / 619 informed Master Beti via a viewscreen that he had picked up an orphan while on the mission . With CT - 5 / 501 serving as co - pilot , CT - 4 / 619 piloted the gunship away from the surface . As the gunship rose , a Vulture droid attacked the gunship , but the rear cannon on the LAAT / i destroyed the fighter with a barrage of fire . CT - 4 / 619 answered Fett ' s questions about the " Candasserri " as they neared the assault ship , and proceeded to dock the gunship in one of its hangars , before taking the orphan to Beti and her Padawan , Ulu Ulix , and then seeing to his duties in the hangar . The " Candaserri " traveled to the gas giant Bespin , where the ship ' s crew planned to offload orphans whom they had acquired from numerous star systems . Upon arrival , CT - 4 / 619 demilitarized the lander that would take the orphans down by painting out all military related markings on the craft , as Bespin was neutral in the war and its officials wanted no signs of the conflict on Bespin . While demilitarizing the lander , CT - 4 / 619 once again met Fett before the orphan was transported to the floating outpost of Cloud City . Personality and traits .
