Both Sir Gawain and the Green Knight are valiant and noble knights. That means that they follow all of the rules of the court and of knighthood. Proper etiquette is always required and proper protocol followed when there is a fight or challenge between knights. For example, they must greet each other, know each other's names, and make sure both know what the battle's rules are about before commencing. There is always respect between contenders. Another similarity is that they both own wealthy armor because of the details on both knight and horse that signify it. Both knights have jewels and costly embroidery on their person and on their horses. The colors and pictures that the knights bare with them on their person or shields are important, too, because they symbolize what they stand for. Both are brave and courageous with how they approach their duties and challenges as knights, too.
