Crested Sprinter (also known as Runner in the SNES/PS version) is an enemy in Chrono Trigger. First appearing in Mystic Mountains in Prehistory, Crested Sprinters share the same sprite as Aecytonyx, who appears in Giant's Claw during the sidequest for the Rainbow Shell. Yellow and small, they sport long tails and a big horn in their head that can be used to trust into their enemy and cause damage.
