Bobby Davis (portrayed by Zack Ward) was a minor character from Freddy vs. Jason. He was the older brother of Mark Davis who had looked up to him when he was younger.
Bobby is already dead long before the events of the film. In 1999, for reasons unknown, he committed suicide by cutting his wrists in the bathtub and bleeding out. His suicide caused Mark to suffer a mental breakdown that saw him committed to Westin Hills Asylum.
In 2003, Mark was attacked in his dreams by the dream demon Freddy Krueger. Krueger took on Bobby's form, appearing to Mark as Bobby had the last time Mark had seen him: in a bathtub filled with his own blood.
