Unkar Plutt is a minor antagonist in Star Wars: The Force Awakens.
Unkar was the only Junk Boss on Niima Outpost, exchanging parts for Scavengers' rations. He also stole the Millennium Falcon from the Irving Boys and began to modify it, detrimentally according to Rey. It was also indicated that he looked after Rey during her childhood on Jakku. However, he was not above verbal abuse towards her or taking advantage of her due to his belief that she was just another asset for him to use.
At the first glance, the Crolute junk boss may looked like a mere abusive slavedriver for scavengers that worked for him, including Rey. But upon seeing Rey with the lost BB-8, he reports the droid's location to the First Order, revealing that he was a loyal follower of the First Order or at least looking to collect a bounty.
On Takodana, after Rey and the defector stormtrooper Finn sought the help of Maz Kanata alongside Han Solo and Chewbacca, Plutt confronted Rey and threatened her, causing Chewbacca to intervene. When the angry Crolute declared he was not afraid of what he considered to be "half a wookiee", Chewbacca showed Plutt the error of his judgment by easily and casually ripping off the screaming Plutt's right arm and tossing it onto a nearby table as Rey watched in shock.
He appears as a cast member of the game.
