Jango Fett was a renowned bounty hunter and the father of Boba Fett, who was his genetic clone. Fett was the leader of the Mandalorians, and later served as the template for the clones of the Grand Army of the Republic.
Jango Fett was born to a family of farmers on the world of Concord Dawn, a planet long associated with the heavily-armored super-soldiers known as the Mandalorians. Fett's father served as Journeyman Protector, having taken over the role when former Protector Jaster Mereel was exiled
After the death of his family, Jango was taken in by the Mandalorian leader, Jaster Mereel, who raised the young boy as he would his own son. He served with Mereel's forces for the rest of the Mandalorian Civil War.
When Mereel was betrayed and killed, Montross attempted to seize control, but his apparent betrayal of Mereel left the other Mandalorians cold. They denounced Montross, and proclaimed that they would follow only Jango. Jango Fett became Mandalore, and Montross slipped off into exile.
Fett led the Mandalorians for the rest of the war until the disastrous Battle of Galidraan. Except for Jango, the Mandalorians were wiped out. Jango, the sole survivor, demonstrated his amazing physical abilities by killing many of the attacking Jedi with his bare hands, but finally surrendered.
Shortly after the Battle of Naboo, Jango was contacted by a man named Tyranus, who offered him a bounty on the deranged leader of a crime syndicate known as Black Sun. Jango had to compete with Montross, the former Mandalorian traitor whom Tyranus had also contacted about the bounty.
Upon completing the bounty and eliminating Montross, Tyranus offered Jango a tempting sum of money for an unusual task: Jango was to be a template for an army of clones. Jango agreed, and soon millions of clones were created in his likeness at the cloning facility on Kamino. Jango, however, asked for one clone produced without genetic tampering, an apprentice and son that would become Jaster's legacy and revive the Mandalorians.
Jango was killed before his time at the Battle of Geonosis by the Jedi Master Mace WIndu, he would, from a certain point of view, live on forever not only through Boba Fett, but also the millions of his clones that went on to served during the Clone Wars, the Empire and presumably, continued to serve the New Galactic Empire.
