Fishman Karate is a martial art that is practiced by certain skilled members of the fishmen race; it is noted that humans can also learn the fighting style, as Koala apparently is able to use it despite being human. While deadly enough on land, Fishman Karate has a number of devastating underwater moves designed to be suitable with the Fishmen strength and speed along with the mobility that goes while under water and, in some cases, a fishman's personal adaptation (fins, teeth, etc.).
