Giant Leech, Resident Evil Wiki
The Giant Leech was a leech infected with the t-Virus that took up residence within the waterways beneath the Raccoon General Hospital. Apparently different from the leeches James Marcus was working with, this leech was, like its smaller kin, extremely sensitive to fire. During the Raccoon City Destruction Incident, a group of survivors attempted to escape the hospital by using the sewer, unaware of the giant leech's presence. They accidently rammed it with a boat, causing it to become enraged
