December 5th kit is another mini figure!
I thought who I knew this guy was, but I had look around online to find out I was totally wrong. This guy is Taslin Brance, a background character in The Force Awakens. He is a Major in the Resistance.
His head has two expression, a smug grin and an angrier scowl. The Sabine figure from the other day also had two expressions, but I didn't notice then. Maybe Major Brance is just mad because his hairpiece is a bit crooked.
