Night Beast
this huge, humanoid creature was left behind by the Massassi to keep Yavin 4 safe until they could return. It is depicted in The Sith War as a huge, red-skinned humanoid with skied scales and horns, while Classic Star Wars depicts it as a large, fish-like humanoid with sharp claws and fangs. Classic Star Wars holds that the ancient Massassi created the beast to guard the temples against an enemy takeover, but The Sith War simply showed Exar Kun and the Massassi placing it in the depths of the Great Temple as a guardian. Originally a Massassi Warrior named Kalgrath, the night beast was held in suspended animation until Admiral Griff launched his atack on the Alliance base on Yavin 4. A TIE Bomber crashed on moon, penetrating the Great Temple's lower levels and cracking the beast's suspended animation capsule open. It then began to roam the tunnels of the temple, destroying Alliance equipment in what it believed was the fulfilment of its purpose. It had some use of the Force, and used it to shield itself from energy weapons. When Luke Skywalker discovered the creature, he and R2-D2 were able to drive it away by using the Force to lure the beast into a space transport. They had programmed the transport for auto-jump, and once the night beast was inside, they initiated the launch sequence. The beast was sent into hyperspace. One of the random jumps performed by the transport brought the beast back to Alliance space. This time, through the Force, Luke explained that the beast would eventually find its former masters by getting onto the transport.
