Green Ambler is a contestant in the race in the Millennial Fair, in Chrono Trigger. They have the same character sprite as a Reptite (possibly indicating a costume).
In one of the bonus endings, where the past is changed so that the Reptites won the battle with the humans and all of the characters are Reptites, the Green Ambler is shown with a human sprite (again, possibly a costume).
Green Ambler wins the race about 30% of the time.
Etymology[]
To amble means to walk slowly or at a gentle pace. Green is a reference to the Reptite costume worn by this racer.
