The male version of a Mary Sue. Usually super strong and muscular, extremely attractive, everyone likes him except for the evil bad guys who only ever focus on Marty Stu instead of themselves, is all about action and being a hero, is perfect in every way, you get the point.
I tried to enjoy the book that my aunt gave to me as a gift, but alas, the protagonist was too much of a Marty Stu for my taste.
