I was watching Star Wars again the other day for the first time since reading about MBTI and I thought Yoda seemed quite ENFP. Here is my reasoning...
1. The first time you meet him in Empire Strikes Back he is playing around with Lukes torch and giggling and throwing things at R2 and seems totally nuts then the next second he is telling Luke the deeper meaning of the Universe.
2. He sits around and does nothing most of the time, but has the answers when people need them.
3. He is a little green man who has better fighting moves than anyone in the universe, but lives in a hole on some weird planet. Definitely strange enough for an NFP!
4. He can't construct sentences in the right order.
