|“||Take care not to wake the Serpent of Gallowmere. It is a most powerful supernatural creature that was bound somewhere withing these chasm walls. If you encounter it, RUN!||”|
– Book, MediEvil
It is first mentioned within a book in the level, which warns Daniel to run if he encounters it. It is basically the evil counterpart to Kul Katura. Unlike Kul Katura who kills Dan's enemies, the Serpent of Gallowmere only charges at Dan. It is encountered beyond the fiery gateway that Dan should pass through if he had obtained the Dragon Armor. It is locked inside of a chest at the end of the chamber. If Dan gets too close to the chest, it will burst open and the Serpent will give chase.
- The serpent can actually be killed. If Dan hits its head enough times with any of his weapons, the serpent will let out a dying sound and leave.
