The Naga were never actually seen, but four of their "agents" were. The Naga captured the dinosaurs and, using their DNA, created the Dinosauroids, Adam and Eve. They also created the Weaponizers.
Many years later, when Ultraman Tiga defended Earth, the Naga released the Weaponizers. After a large battle, Tiga defeated the two Weaponizers before the bombs could collide. Catching one in each hand, Ultraman Tiga flew into space and hurled the bombs towards the Naga's spaceship. He fired a Zeppilion Ray which struck the bombs as the hit the spaceship, destroying it and the Naga.
