Ace

Ace was an employee of the resort on Isla Bonale, who provided Stan and Leslie with their snorkeling equipment. When an Umbrella cargo plane crashed on the island and spread the G-Virus, Ace was turned into a zombie. He attacked Leslie and was speared by Stan, then fell into the ocean where he was eaten by a moray eel, with the end result that the eel became infected with the G-Virus and mutated into a gigantic monster.
