Submarimon

Submarimon
Submarimon, the Reliable Guardian of the Sea (渦巻く誠実), is an Aquatic Digimon whose name and design are derived from the Submarine and the narwhal. It armor-digivolved through the power of the "Digi-Egg of Reliability". It has the "Water" attribute of that Digi-Egg, and those that don this Digi-Egg demonstrate their true power underwater. It swims freely around the ocean, and as for the techniques that are unleashed during underwater battles, if the opponent is not a considerably aquatic Digimon, it will be unable to oppose them.
