|“||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
The Serpent of Gallowmere is first mentioned within a book in the Gallows Gauntlet, which warns Daniel to run if he happens to encounter it. Unlike its brother Kul Katura, who kills Dan's enemies, the Serpent of Gallowmere only charges at Dan. It is encountered beyond the fiery gateway that Dan needs to pass through using 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 to Dan for a limited time.
Though it is recommended to just avoid the Serpent while it is chasing you, it 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. Doing so in the PS4 remake will unlock the "If It Slithers, I Slays" trophy.
