Mermaid (Pixie) MRAdv
Undine / Windine / Mermaid

This monster first appeared in Monster Rancher 3 under the name Windine, where they were classified according to where they live. Windines live in the ocean region known as Goat. The name and original design of this monster was meant to be a reference to the older main-breed species Undine, although it should not to be confused with this race, which are actual elemental water spirits. Although the name was briefly changed to Mermaid (another type of Undine), the basic design has stayed the same.


The name Windine is a combination of the words wind (since it can also control wind) and undine, a water elemental spirit mentioned in the alchemical works of Paracelsus.

Mermaids are half-fish, half-women creatures that appear in legends from hundreds of countries across the globe, often seen by sailors.
