Forrest Kaysen



Forrest Kaysen is the main antagonist of video game, Deadly Premonition.

At first, he looks kind to almost everyone, even to Francis York Morgan, the protagonist. Later, he is questioned by York himself for the murders happening at Greenvale. Kaysen is freed, but York still has suspicions for him.

When Emily Wyatt is attacked by Carol MacLaine, Kaysen is requested to take care of her while York deals with the Raincoat Killer.

York confronts Kaysen in a theater where he has planted a sapling to Emily. She begs the former to kill her. It is revealed that Kaysen is the one whom Zach confronted in his childhood. He has planted a sapling on his mother; as a result, she begs his father to kill her, but he didn't and died as the sapling sprouts. Zach's father is depressed of this and shoots himself in the head. Kaysen has found Zach and scratches the right side of his head, explaining the scar. He traps him in a dreamworld where Zach has met York to protect him. This reveals that York is an alternate personality created when Zach is traumatized from what happened in his childhood.

Zach takes over and fights Kaysen where he kills him.
