Koo

Koo is mostly "existent" to keep it's friend, Ness, company and to guide her in the right direction. Most of the time, the water dragon just holds .

Koo is mostly the brains of two. Always interested in science related things. Sometimes uses big words to sound more intelligent. Koo is caring, smart, and reliable, but is also afraid or cautious of almost anything living (Especially humans). Whenever the water dragon is afraid of something, it hides and leaves the fighting, or talking, to Ness. Koo Does have a little sense of humor but doesn't show it. Koo rarely gets angry. Sometimes feels insulted if someone calls it "cute and cuddly".

It doesn't fight and is physically weak, but if it has to it can control a small amount of water (about the size of a pond). Koo can also turn somewhat invisible when in water but only for about 7 minutes at most because it uses a lot of energy. If used more than that, Koo could possibly die. Koo's horns are the hardest part of it's body, but it is also what keeps Koo alive. If they're ever broken or damaged Koo could die as well. If Koo is ever cut or hit anywhere on its body, it can reform quickly with more water.
