Tanmarin MR4

Originally, this imp monster had a dolphin-like tail and orange spines at the ends of its ears, but eventually took on a more Lesione-like appearance, with the beady eyes and the dewdrop-shaped head crest. Both versions carry a small trident. When it appears in Monster Rancher 3 under the name Oltan (a game that does not allow combining), it is impossible to determine its actual sub-type. Instead, monsters are classified according to where they live. Oltans live in the ocean region known as Goat.

Etymology Edit

A combination of the words Gitan and marine.
