Funquat

Freddie Funquat was surfer beach bum who didn't have much of a future, until one day while out catching some waves he found himself tangled in a patch of radioactive seaweed. As he was dragged down the ocen bottom Freddie didn't drown, but instead found himself mutated into a strange green creature capable of breathing underwater. Freddie used his new found aquatic prowess to become a worldwide champion surfer and obtain untold fame and riches.

Ganoid

Ganoids are bipedal creatures which evolved from sea-going, eel-like ancestors. They are still semi-aquatic, and are capable of respiration under water as well as on land. They have a ritualistic warrior culture, and there are often multiple conflicts occuring at once across the surface of their native planet.

Itchlodyte

Itchlodytes are primitive, proto-fish men which live in a small nomadic community along a deep pacific trench. They follow a large pod of whales and exploit them the same way that Native Americans followed herds of buffalo. This has brought them into open conflict with whaling vessels, who they view as destroying their way of life. Itchlodytes have been known to foul propellers, drill holes into ships, or board them and fight hand to hand in extreme cases.

Fishmonkey

Strange aquatic simians, Fishmonkeys live in the deep seas. They are notable for seemingly appearing overnight - one day from out of nowhere thousands of schools of the bizarre mutant just appeared out of nowhere, with no prior sightings or evidence in the fossil record. This has lead many to speculate they are extraterrestrial in origin.
