A Reptite is an enemy monster found in 65,000,000 B.C. in Chrono Trigger. There are actually two types of Reptites. The first is encountered during Crono's first trip to the Prehistoric era. The second is a much stronger Reptite that is encountered on the second trip to the era. Both are listed here.
Reptites are also found in the Reptite Lair.
The second form of Reptite is encountered in the Tyrano Lair.
