Ornitholestes is a special enemy in Final Fantasy X, created in the Species Conquest of the Monster Arena when three of each Reptile species fiends have been captured, with the exception of the Cave Iguion, which is only encountered when capturing fiends is not possible.
With high Agility and Evasion, Ornitholestes can be difficult to hit. Its Poison Touch attack inflicts Poison and reduces 75% of its current HP of one character. When its HP gets low, Ornitholestes will use Drain Touch, which can siphon a large amount of HP from a character.
Ornitholestes (from the Greek ornithos meaning "bird" and lestes meaning "robber") was a small, raptor-like dinosaur that lived during the late Jurassic period in what would become North America. It typically fed on small lizards and mammals.
