Reptite
Reptites were the first sentient race to evolve in the world of Chrono Trigger. As their name suggests, they are a race of evolved reptiles.
It is known that the human race evolved due to the quantity of Dreamstone in the planet's crust, so it can be assumed that the Reptites may have evolved for the same reason.
Society
During the era of Prehistory, they already have a society at around the same technological level as humans have in 600 AD, if not moreso.
The Reptites are led by their lord, Azala. The center of their society was Tyranno Lair, which sat atop a high mountain in a volcanic mountain chain.
They used other reptilian creatures like Megasaurs, Avian Rex, and Terasaurs as guard-beasts for their lairs.
Physiology
Being reptiles, Reptites are stronger and more hardy than humans. Their tough, scaly skin protects them from dangers. However, they are very sensitive to lightning, which can shock them.
Reptites are cold-blooded, which is why their castle sat amid a chain of volcanoes.
Hunting Humans
The Reptites were always engaged in fights with the fledgling human race. During the course of the game, they burn down the village of Laruba and kidnap many people.
The Coming of Lavos
When Lavos came to the planet, he crashed on the volcanic mountain where Tyranno Lair was. All Reptites on the mountain died in the explosion, and the rest died out as the first Ice Age began shortly thereafter.
Connections in Chrono Cross
The Dragons mentioned in Chrono Cross appear to come from yet another world from the two in the game, one where the Reptites did not become extinct.
