Katos are small cat monsters that look very old, exclusive to Monster Rancher 2. Although not very strong in power, their intelligence and accuracy are very high. Katos also like to drink oil and smoke a pipe. They have the power to breath fire after they drink their bottle of oil (which is actually sake in the Japanese verson). They also use attacks involving their long, razor sharp claws.

The Kato has been subjected to several censors in the American versions. Its two favorite items, "Cigarette" and "Sake" were changed due to America targeting younger audiences. The cigarette item was edited out completely while the sake item was renamed "Olive Oil." In addition to this, the move "Flame" used as the Kato's special attack was taken out of the game's normal learning methods. The move can be learned through extensive combination. This was most likely done to keep the illusion of Kato preferring oil to alcohol.

Etymology Edit

The name kato is actually a mistranslation of the word gato, which means "cat" in several languages. However, there are several famous Asian fighters named Kato as well. Its Japanese name is Ākero (アーケロ).
