GeoGreymon

GeoGreymon is a Dinosaur Digimon. He is a subspecies of Greymon. His name originates from the Greek prefix geo, meaning "earth", and grey, meaning "old" or "ancient".

His appearance is similar to the original Greymon, but has different markings, has a tensed-up look, has far more teeth visible, and spikes on his arms. He also sports a re-designed muscle structure, including a more defined chest which lacks the blue stripes of Greymon.
