Nagas were first introduced in Monster Rancher 1 and were obtainable at the beginning of the game. They have continued to appear in almost every Monster Rancher game since then, and played a major role in the anime series. Nagas are humanoid serpents with stingers on their tails. They have a variety of attacks, using their fangs, broad shoulders and sharp claws to create powerful combo moves. They also seem to be able to generate some types of dark energy, like when they use their "Lifesteal" or "Evil Shot" techniques. Unlike most monsters, the animation style for the Naga from Monster Rancher 3 was kept for both of the Advance games, as it was easier to animate than the designs from the first two games. It was changed again for Monster Rancher 4 and stayed the same after that.
