Scarface is the name of a Yautja who participated on a hunt on the planet Earth.
During his time on earth, Scarface was gravely wounded and much of his races technology was left on the planet. For revealing the existence of the hunt to the prey species, Scarface was banished by his people to a far off hostile world where he only possessed a Combistaff to protect him from the native creatures.
Years would pass and Scarface would find members of his race return with a task for him which was to return to Earth and retrieve all the stolen technology as the Human species had deciphered the hunting tools left behind and used it to kill future Yautja hunters.
