You don ' t understand . NTJs are the ultimate feelers . First you have the INTJ , who may look like an aloof serial killer on the outside , but is deeply driven by Fi . Their tsunderekuudere appearance is carefully crafted so that nobody manages to take off their mask and unveil the sensitive , easily scared kid that may be smarter than everyone else but has no idea how to connect to the ones around them . Now we have the ENTJ , who ' s even more of an alpha personality than the INTJ but who actively suppresses their Fi . Once it comes out though , the throatcutting monster of logic turns into an almost cute being that deeply cares for the people around them . All of this happens under the supervision of Ni and Te . In other words , if you fuck with their Fi , Ni and Te will annihilate you and their Se will make it look as elegant as possible for any bystanders .
