Gai MR4
Guy / Gai / Tao

A feathered breed of Zan with the speed of the species and incorporating the discipline and martial artistry of the Raiden species. This monster's design does not change much throughout the series, but its genetic makeup and name is changed several times. In Monster Rancher 3, monsters are classified according to where they live. Guys live in the forest region known as Morx. In Monster Rancher Advance it is even mistakenly given a Momo sub-type since Raiden does not exist in that game. Its genetic makeup is finally righted in Monster Rancher Advance 2, but it is renamed Tao for that instillation.

Etymology Edit

Gai is a character in the Naruto anime series (Also called Mighty Gai) who trains his pupils through harsh punishment, thinking it will make them stronger in the end.

Later named for Taoism, a religion in Japan that originated in China, which incorporates a great deal of shamanism and yin yang philosophy.
