How to get rid of Gluttony if he was human in a few easy steps.
Put up a long ass table, and put tons and tons of food on it. Get your pork chop suit ready, and go find Gluttony.
Dress up like a pork chop, and prance in front of Gluttony. His mouth will start to water, and run after you. Once he starts to run get the hell out of there as soon as possible.
Run past the table and get behind the corner of the alley. And wait for the fat ass Gluttony to show up.
Once he shows up he will be so fixated on the massive amount of food, and forget all about you. He will eat all of the food, and fall over backwards because he was actually full, for the first time ever.
Get out of the pork chop suit, and walk over to Gluttony. When you see him his mouth will be wide-open, eyes in the shape of an x, and he's fast asleep.
Run away before he wakes up and wants to eat you.
