Zentilo was a male human who worked for the Republic Army as weapons and armor expert during the Cold War between the Galactic Republic and the reconstituted Sith Empire and beyond. During the Galactic War, he was assigned as a weapons and armor modification specialist to Strike Force Oricon, who were sent to the moon Oricon to counter the Dread Masters' threat. Although the operation was initially a disastrous failure and many members of the team died, he was able to survive the landing and has provided her services in the strike force's camp ever since.
