An aloof Aquatic Digimon with an aversion to groups. Regalecusmon is a pirate, repeatedly raiding other Digimon’s territory and pillaging their feeding grounds. Its overwhelming strength also makes it the undisputed conqueror of the deeps, where it stands at the top of the food chain. Its sword, which it made from a horn it tore from a Zudomon’s head, together with the giant pincer on its left arm, serve as symbols of terror that instill fear in any who lay eyes on them.
Its special moves include Briona Strike, where it pierces foes with the sword in its right hand while also blasting them with lightning, and Reactor Discharge, which involves discharging plasma from its pincer to blow away everything in its surroundings, including the seawater.
