Something that Eva
pilots wear. They are designed to conform to the curves of the pilot's body, to make synchronising with an Evangelion
easier and to provide medical assistance to the pilot
if needed. Of all the uses of a plug suit by far the one most appreciated is how well they show off the pilot's body. Imagine skin-tight leather all over and you are beginning to get the picture. They come in different colours too, Red for Asuka
, White for Rei
, Purple for Shinji
The special clothing worn by Eva pilots. It works to raise the synchronization rate and protect the body, etc. This suit is molded as a single piece covering from neck to toe, and has a structure similar to a wetsuit. Although rather loose immediately after it is put on, the suit adheres to the body by clicking on a switch on the wrist.
