Knight of the Dark Face

I don't know if later in the novel Don Quijote encounters a "dark knight" figure but I think it would be cool. Today in class we assumed our roles for Friday's exercise and I decided to be the antagonist of Don Quijote, my character will wrong the rights instead of righting the wrongs. Really for my role to effective I will need the person that portray Don Quijote to be present in much of the dialogue because I will essentially base my character on doing the opposite of Don Quijote. I'm thinking that maybe since Don Quijote is known as the "Knight of the Sad Face" then perhaps my character could be the "Knight of the Happy Face." Actually scratch that my character will be known as the "Knight of the Dark Face." And in reality he would have an all black armor suit including a black steel sword. As the dialogue continues I would just like to do the opposite of whatever Don Quijote does, but behave in an equally mad way. For example, if Don Quijote were to save a beautiful damsel from being robbed by a group of criminals, I would save the group of mistakenly convicted from the heathen devil woman. Also it would be neat to create a battle between Don Quijote and his dark nemesis and have them end in a tie. Of course since they are equal matches they find out that they are long lost brothers. The "Knight of the Dark Face" is also named Francisco Quijote de la hampa de La Mancha. I mean I guess that I have a plan going into the role play, but we'll see how it goes because after all there are plenty of other people playing characters within the story.
