‘Force Awakens’ Deleted Scene, Chewbacca Rips Off An Arm
We learned in A New Hope that it was unwise to upset a Wookiee. They tend to "pull people's arms out of their sockets." Han Solo explains it in this scene while Chewbacca and R2-D2 play a game of Dejarik.
As much as Chewie has done to help the Rebellion, and then the Resistance in The Force Awakens, we never really got to see him show such violence. But, with a deleted scene from The Force Awakens we now get to see the Wookiee show his temper.
If you remember from the beginning of the movie Unkarr Plutt. He's the junk dealer that would buy items from people like Rey on the planet Jakku. Well, he apparently made his way to Maz Kanata's when Han, Chewie, Rey and Finn happen to be there as well. He ends up confronting Rey, and that's when Chewie steps in. And let's just say, it does not end well for Plutt.
