A deep-sea breed of Naga that has dark blue skin and large gills on its chest that allow it to live underwater all the time. It could possibly have a Zilla sub-type, but because it is exclusive to Monster Rancher 3 (a game that does not allow combining) this is impossible to determine. Instead monsters are classified according to where they live. Mermen live in the ocean region known as Goat.
Etymology[]
A merman is a male Template:Ns, a legendary creature who is half human and half fish.
