It specializes in underwater activities due to the power of the Digi-Egg, and it is capable of moving quick like a fish. Also, its armor has a high capacity to withstand water and pressure, so it is able to dive into parts of the deep sea even further than fellow Aquatic Beast Man, Divermon. With its diving ability, it will even contend for first place with Whamon.
