A Digimon resembling a mermaid from folklore, taking up residence in the coldest seas of the Digital World. Unlike most Digimon, singing comes easily to Mermaimon, and it offers up a charming tune when the occasion warrants. Due to its avarice and weakness for treasure, it will charm other Digimon before taking the opportunity to plunder their data (treasure). Because of this, there is thought to be a colossal cache of data hidden somewhere in the Net Ocean. Still, once the looted data becomes Mermaimon’s, it loses all interest and throws it away. It uses its special move Charm Plunder to draw near with its beautiful mermaid-like figure before suddenly stabbing its foe with a golden anchor, or Northern Cross Bomber to spin its golden anchor chaotically and crush its foes.
