A Digimon that Digivolved by absorbing data from various types of musical equipment and violent rock music. The armor covering its body is equipped with various functions, such as speakers that amplify the sound taken in from its chest microphone, and an effector that alters its voice. Its main speakers deploy during battle, allowing it to sing at an extremely high volume.
As they will be exposed to the loud and raucous noise emanating from its body, any who oppose Loudmon are unable to perform at their best. At the same time, Loudmon will get even more hyped by the sound. A peculiar Digimon with an unconventional way of thinking, Loudmon thinks of a battle much in the same way as a live concert or a gig. Performing at its best takes priority over trading blows with its opponent, and the outcome doesn't matter. After a battle, it will shower with praise any opponent it deems to have given its all, and it will even work together with them for a brief period of time.
As for Loudmon's special moves, Metallica Edge rips a foe to shreds with claws that have been sharpened by sound-induced vibrations. By shouting into the microphone on its chest, a maximum volume shockwave is released from its shoulder-mounted speakers with Deep Purple Blaster.
