Kosh is the brother of Sinch and Tanch, and his personality lies in stark contrast with the two.

Kosh was created as the strongest newt, which means very little when just about everything is stronger than a newt. Kosh was awoken by Sinch and Tanch, and immediately showed his colors as an intuitive strategist, kind soul, and absolute meathead.

Kosh enjoys slaying invasive bugs, lifting, and letting things happen to people he doesn't like when they depend on him the most.
