Jango Fett was a human male born on Concord Dawn, where his family was killed by the Death Watch, a splinter group from the legendary True Mandalorians. Jango was adopted by Jaster Mereel, the leader of the Mandalorians. When Jaster's second in command, Montross, betrayed him to the Death Watch in a trap ending with Mereel's death, Jango Fett rose to become the leader, or Mand'alor, himself. At the Battle of Geonosis, Jango died at the hands of Jedi Master Mace Windu, who beheaded him in the Geonosian Arena with his purple bladed lightsaber.
