Mermaimon is an Aquabeast Digimon. This Digimon, which takes the form of the mythical Mermaid, is based in seas found in cold regions even in the Digital World. It is good at singing, which is unusual for a Digimon, and does so with a very beautiful timbre, charming those who listen to it. However, because it is greedy and extremely fond of treasure, it charms those with its singing when it feels attracted to the treasure, even if their data (treasure) belongs to other Digimon, and then takes the opportunity to loot from them. For that reason, it is rumored that it hides a vast amount of data somewhere in the Net Ocean, but it loses interest in the data it has looted once it falls into its possession, and discards it.[4]
