Ronin is a fierce, disciplined warrior who has difficulty showing his emotions. However, he proved his rare humorous side when he mocked Professor Bomba's manner of speaking, much to Mary Katherine's disapproval, his taunting of the Boggans and ultimately his teasing "tough-love" manner with Nod. After Nod's father died, Ronin become Nod's mentor and looked out for the young lad as well as he could--which Nod only truly realized when it was nearly too late. Ronin has a long history with Queen.
