A former madalorian soldier, Jango Fett was one of the finest Bounty Hunters in the galaxy.
Shortly after the defeat of the Mandalorians at the battle of Galidraan Fett escaped the asteroid prison of Oovo IV unlike many of his comrades. Only he and one other are known to have escaped, the other being Montross a long time rival of his and the cause of death of his adopted father Jaster Mereel at Korda IV.
After the death of his parents at an early age, Jango crossed paths with a Mandalorian soldier named Jaster Mereel who took fett under his wing and raisd him.
Fett fought many battles wilst with the Mandalorians until they're eventual destruction at the hands of the Jedi led Death Watch.
Fett managed to recover his iconic Mandalorian armer which he applied to great affect in his new profession.
Eventually he was hired by Count dooku under the alias of Tyranus (unknown to fett the jedi who helped defeat the Mandalorians) to eliminate the leader of the Bando Gora (a cult lead by a rogue dark jedi) who had taken over the death stick trade with their new highly poisenous brand. Despite Fetts better judgement he couldn't turn down the fantastical bounty of five million credits that dooku posted.
After completing his mission (in witch he met Changeling Zam Wessel and stole a prototype Fire Spray named Slave 1 from Oovo IV which at the destruction of both the prison and his ship he took as his own) he collected the bounty and was presented with another propasition by Dooku, in echange for continual pay he would be the template for a clone army on Kamino, which Jango excepted at the request that he have an un alterd clone for himself which he raisd as his son and named Boba
Ten years later and with turmoil in the galaxy Fett was at the Battle of Geonosis, where he met his end in a confrontation with Mace Windu and was decapitated. After the battle his son boba inherited his ship and armor and went off to follow his own career in bounty hunting having been traind by his father.
