Shrek is overly aggressive and hostile towards strangers who wander into his swamp, an example of this is when several villagers came to kill him but then were left terrified when Shrek described ogres as ten times worse then giants after they fled, the ogre gave a hearty chuckle and warned them to stay out. However behind this tough demeanour, Shrek is incredibly insecure and sought recluse from everyone as they judged him as a monster before getting to know him and believed that he was better off alone. When meeting new people Shrek is heavily sarcastic, when meeting Donkey the first time and asked for a place to stay Shrek agrees only to say no the second time he asks. Due to all the people he meets Shrek is used to being treated like a monster and is left surprised when Donkey has no problem with his appearance or his ogre roots.
