Lavos (ラヴォス Ravosu) is Chrono Trigger's main antagonist and final boss, an alien parasite which crash landed in the year 65,000,000 B.C. It was named "Lavos" by Ayla, a word she made up from the root words "La" meaning "fire" and "Vos" meaning "big" in the Iokan language. Lavos' true name (if it even had one) is unknown.
