EXE is a dark, cruel, and crooked being, hellbent on vengeance against those who wronged him which mostly being X, and killing others for his own necessity and setting on conquest of all he can seize. He lives for the suffering of all other life, and seeing others tear themselves apart mentally. If it sees you, you only have a short amount of time to flee. After that, there's no telling what will happen to your remains in the aftermath. He is anywhere. And if he's not there, he will be soon.
