As an ENFJ, you are such an extroverted other-pokemon-pokemon that you tend to speak to and identify with others on their own level. Your Color-Change ability lets you do this with ease, even letting you change your type to match the pokemon you're attacking or talking to. Friendly and upbeat, you love situations and things concerning others and probably hate to be alone.
