Leatherface (Texas Chainsaw 3D)

Leatherface (real name: Jedidiah Sawyer) is the main antagonist turned main protagonist of Texas Chainsaw 3D.

Biography
The film begins directly after the events of the 1974 film, in which a mob led by Burt Hartman burns the family's house to the ground, and Leatherface becomes the sole survivor of his family except for his baby cousin Edith, also known as Heather, whom a member of the angry mob rescues and smuggles away. Many years later, when Heather returns to the local area with her friends, Leatherface lives in the basement of a mansion belonging to their recently deceased grandmother, who has been caring for him for the past 20-odd years.

Due to her passing away, Heather - as the only identified living blood relative - inherits the mansion. Leatherface kills off Heather's friends one by one, not realizing that Heather is related to him and nearly kills Heather before she escapes. After traveling to the local police station, Heather discovers her ancestry and the fact that Leatherface is her cousin.

Upon discovering he is still alive, Burt Hartman, now town mayor, sets out to kill Leatherface once and for all, and since Heather is a member of the same family (the "Sawyers"), he develops a vendetta against her as well. Leatherface once again attempts to kill Heather before recognizing her birthmark, and realizing his kinship to her. Burt attacks Leatherface; Leatherface ultimately kills Hartman by pushing him down into a meat grinder. Later on, Heather finally reads a letter given to her by her now deceased grandmother, revealing that she simply wanted Heather to take care of Leatherface. His name is revealed to be Jedidiah Sawyer, known as "Jed" for short.

In a post-credits scene, Heather's adoptive parents arrive at the mansion, greedily discussing how they plan to split the assets Heather now owns. Leatherface then shocks them as he answers the door, chainsaw in hand.
