(n.) A mythical creature with the head of a cobra, the neck and tail of a brachiosaurus, and the body of a modern tank. One of the few species to actually have a catch phrase: "Amaze your friends. Devour your enemies. Then devour your friends." Also, the only creature known to have evolutionarily developed a complex ballistics system as a means of predatory attack.
My pet cobrachiosaurus tank destroyed my old high school in a matter of 3 minutes. It was AWESOME.

Tank, tank, here comes the cobrachiosaurus tank!
