I was curious to what people's thoughts on Hetalia's MBTIs. I haven't found too many good discussions, so...
Italy: ENFP. He seems to be putting on an ESFP mask for many potential reasons.
Germany: Some sort of XSTJ. I can't decide between ISTJ or ESTJ. I'm leaning towards ISTJ, though.
America: I'm conflicted on him. He's definately some sort of EXXP, but I'm not sure what... I tend to lean towards either an ENTP or an ESFP.
A few others:
Romano: INTP. (?)
Prussia: ISFP with some bad narssasism.
Austria: XNTJ. I lean towards ENTJ.
Hungary: ENXP. I lean towards ENFP.
Belarus: A really crazy INTJ.
