Gatchmon is a bipedal cat-like creature with white fur, yellow eyes, a tail, a small horn on the nose, and small fangs. It has metallic feet with three toes each and a large claw on each toe, and metallic hands with three clawed fingers each. It has a magnifying glass-like appendage on its tail, and a yellow looking glass mark on its belly. It wears a red helmet with two horns forming a "V"-like shape, and a magnifying glass-like object on the helmet, the latter of which references its search abilities. Like all Appmon, it has two cables on its back to allow Applink.
