Gaossmon is a Digimon whose name and design are derived from the Gasosaurus (Gasosaurus constructus). A tiny Digimon that is strong, at least in its competitive spirit, and in any case it barks well. It is also quick to flee, and extremely swift. Although it is almost impossible to track it after it runs into the bushes, you can easily find its location because it will soon begin to bark. Since it specializes in running on land, it is totally incapable of swimming, as it dreads water. In fact, it can't even cross a 10 cm deep brook, and sometimes, you can run across a Gaossmon that has nearly drowned and passed out in a puddle of water.
