Jango Fett

"It belongs to a bounty hunter I killed on Geonosis. A man named Jango Fett." "You mean...the clone template?" "Yes, strangely enough he had a son. Or at least a clone he regarded as a son. His name is Boba Fett." "I remember him now. Obi-Wan listed him in his report on Kamino."

Jango Fett was a Mandalorian male mercenary and bounty hunter who served as the template for clone troopers. In exchange for being cloned, he received an unaltered clone as his son, named Boba Fett, who went on to become a notorious bounty hunter like his father.

Biography
"I recently encountered a man who wore Mandalorian armor. Jango Fett." "Jango Fett was a common bounty hunter. How he acquired that armor is beyond me."

- Obi-Wan Kenobi and Almec Jango was born on the planet Concord Dawn and became a Mandalorian Foundling as a child, raised in their ways. Even though Jango played a role in Mandalorian history as a veteran of the Mandalorian Civil Wars, officials of Mandalore disavowed any connection to Fett, claiming that he was simply a bounty hunter who somehow stole a set of Beskar armor, an artifact from their planet's troubled past. Jango would eventually become known as the greatest bounty hunter in the galaxy.

Ten years prior to the battle of Geonosis, Jango was hired by Count Dooku to be the template for the clone trooper army on the planet Kamino. In return, along with a large amount of credits, he requested for an unaltered clone: a clone that he took up as his own son and named Boba Fett.

Jango Fett's son, Boba, later teamed up with Aurra Sing and Bossk to avenge his father's death by attempting to murder Mace Windu, the very man who killed Jango back at Geonosis at the start of the Clone Wars but failed. Boba would eventually don his father's armor and follow in his footsteps as a bounty hunter.
