Elias Voorhees

Elias Voorhees or simply known as Mr. Voorhees is the abusive husband of Pamela Voorhees and the father of Jason Voorhees.

Jason vs. Leatherface
In this version we see through flashbacks that Elias regularly abused his son, Jason, for his deformities and the fact he was mentally handicapped. Regularly chasing Jason while beating him with a belt, calling him a monster and mocking him that he should "take it like a man" claiming he couldn't run to his mother forever. As Elias chases Jason he finds Pamela (referred to as Doris in this comic) who having had enough of his abusive behavior towards both her and Jason promptly kills him with a machete to the head.

Friday the 13th: Pamela's Tale
In this version Elias is portrayed as a coal minor in Ohio during the 1940's. Having formed a relationship with Pamela who was only a teenager despite Elias himself appearing to be a bit older they lived in a small trailer together. If Pamela made any mistakes or if Elias even thought she may of made one, Elias would verbally and physically abuse her. Unknown to Elias, he got Pamela pregnant with Jason and continued to beat her when annoyed. As Pamela would mutter to herself believing she and Jason could communicate to one another, Elias who was annoyed decided to violently beat and it's implied rape her before going to bed. Fearing for both her and Jason's safety, Pamela kills Elias with an ax before destroying the trailer they lived in and dumping Elias' remains in Crystal Lake.

Personality
While versions vary to some degree one thing that is shared in nearly if not all versions is that Elias was an abusive man who tormented his family. He is said to of been a man who rarely spoke and was in the films either unfaithful to his wife or abandoned them for unknown reasons.

Trivia

 * Due to the never appearing in the films it is unknown if he was abusive to his family in that continuity, the main writer of the first film admits he never created a backstory for him and could only guess he left due to how overprotective Pamela was of their son. For this reason it's unknown if the films version was a villainous character as well.
