(Capcom's primary storyline)
Dr. Henry Sarton was a researcher at the Arklay Laboratory. He injected a plant living in Point 42 to test the effects of the t-Virus on plants, causing it to become gigantic and dangerous. During the early days of the Mansion Incident, he recorded as much information as he could on a plant growing at Point 42. Henry most likely became one of the many zombies that roam the estate.
