Who will be your destructor if Gozer makes you choose?

For those who are familiar with the movie Ghostbusters, recall Gozer, that demon god(?) who gave our heroes the chance to pick who their “destructor” will be.

Dan Akroyd’s character chose the Stay Puft Marshmallow Man assuming that was one character who can never destroy them. Of course, Marshmallow Man came in as a mean giant. LOL

Assume that Gozer would do the same, she will “monsterize” your destructor. Still you wanna pick the most harmless character there is so who or what will it be-?
