Mary sue/ Gary stu from wikipedia

A Mary Sue or, in case of a male, Gary Stu or Mary Stu is an idealized fictional character, a young or low-rank person who saves the day through extraordinary abilities.

Mary Sue stories—the adventures of the youngest and smartest ever person to graduate from the academy and ever get a commission at such a tender age. Usually characterized by unprecedented skill in everything from art to zoology, including karate and arm-wrestling. She saves the day by her wit and ability, and, if we are lucky, has the good grace to die at the end, being grieved by the entire ship.
