He is a deformed, monstrous serial killer who is known for wearing a hockey mask to cover his deformities and intimidate his enemies and murdering those who dare to step foot in his hunting grounds, Camp Crystal Lake out of vengeance for his mother Pamela whom he witnessed being decapitated. When he was a human, Jason was exceptionally durable and difficult to kill, along with being very strong, but he could still feel pain and eventually was brought down by Tommy Jarvis, who continuously hacked away at him with his own machete. However, this would not be the end, for years later, he'd be brought back from the dead via a lightning strike by complete accident by Jarvis as an undead revenant which granted him supernatural abilities.
