Wu Kong has many positive aspects to his personality. For one, Wu Kong is a confident, optimistic person. He doesn't just go down when he faces hardships, he devises ways to overcome them, putting a smile on his face even when he has been defeated numerous times. Wu Kong is also a very intelligent immortal. He puts emphasis on knowing his enemies and using different strategies to defeat them. And Wu Kong is a master at that - finding out his opponent's weakness and using it. Anyway, he can ask for reinforcements virtually everywhere. His outgoing, friendly personality and his notorious reputation makes sure of that! Wu Kong shows no mercy when it comes to evil - he eliminates all the demons the pilgrims meet on their journey. He has a strong sense of justice and during the journey, he helps out humans who face problems caused by demons, reuniting families and saving entire countries. But best of all, he has a wicked sense of humour. Poking fun at Ba Jie is just part of it.
In short, Sun Wu Kong symbolises hope and justice.
