What are the origins of Jango-Fett (star wars)?

Answer 1

Jango was born into a warrior race called the Mandalorians. He was orphaned on the planet of Concord Dawn, when his family was murdered by a faction of Mandalorians called the Death Watch. Jango was a young boy when the war between the True Mandalorians, led by Jaster Mereel, and a traitorous scion of their ranks, the Death Watch, led by Vizsla, begins. Jango was taken in by the Mandalorian leader after Jango helped the True Mandalorians escape from his family's farm, when the Death Watch set fire to the fields. Jaster trained Jango to be a strong warrior, and Jaster was later murdered by Vizsla, the leader of the Death Watch. Jango Fett became the new Mandalore, and avenged Jaster Mereel's death. Later while fighting to suppress a popular revolt in the Galidraan system, the Mandalorians ran afoul of the Jedi Knights who wiped out most of the Mandalorians and delivered the survivors to the governor of Galidraan. Jango became a slave but he used the next couple of years in prison to regain his strength and plot his eventual escape. He then exacted revenge on his captors, reclaimed the Mandalorian armor, destroyed the Death Watch, faced off against Visla in a one on one showdown, resulting in Visla being eaten alive by some animals. He then set off on his own as a bounty hunter.
