Actually, I think both ISFP, INFP, INFJ and ENFP will do this. I think it is because they all can be similar and they may relate a lot to both the INFP and INFJ type. But typing as them only to be seen as special or "unique" sounds like what an xxFP is more likely to do than an xxFJ.
Type most likely to get a child and then train it up like it was a dog?
Here's another shot at One Piece MBTI, I've refined a few types overtime, I'll focus on just the straw hats for now and update the rest later.
