The Giant Rabbit is a Novelization-exclusive monster. It appears only during the 'Elevator Scene' chunk of the book.
Physical Description & AttributesEdit
As its name implies, the Giant Rabbit is a normal rabbit, but of an abnormal size with, as mentioned briefly in the book, "oversized teeth". It was most certainly released during the System Purge.
The Giant Rabbit is most likely a reference to the 1972 science fiction film Night of the Lepus.
