Like all clones, I was a genetic copy of the once renowned bounty hunter Jango Fett, although, due to the millions of clones straining what DNA was left of the deceased Fett, it was speculated by the Kaminoan Administrator Lama Su that I, along with the other cadets in my unit, were too deficient to be a soldier. We lived in the barracks of Tipoca City, where I endured physical and mental training, and was identified by the designation CT-21-0408 as a cadet.
I sarcastically received the nickname "Echo" for having a tendency to repeat orders during training exercises, annoying my fellow troopers. I was born on the planet Kamino (Later renamed Jang O A 2 after a catastrophic event in the system dried the planet up and its former history forgotten), as all the clone troopers of the Galactic Republic were.
