The Hunter, also dubbed "The Mogasaur" by Daniela, is a gigantic monster of Setrákus Ra's creation. It is the size of the Statue of Liberty, and was unleashed on New York City to hunt the Garde. Number Five revealed that the Hunter had the four Loric pendants built in to the eyes of the beast.
The Hunter is very durable. Five used his Externa mixed with John's Lumen to turn him on fire, flew through the eyes of the Hunter, and all that did was anger it. The Hunter only stopped when Daniela and John used the Stone Gaze Legacy to turn the Hunter to stone.
