Samekujira

A natural creature from the ocean, Samekujira remained in deep waters until a tanker got it's attention for entering his territory. A day later Samekujira was somehow lead to Japan and arose from Tokyo Bay. ZAT and Ultraman Taro soon came to the scene, but during the battle a fisherman from outer space named Alien Valkie interfeard. Valkie got in the way of Taro as Samekujira was gliding to impale his head blade into his enemies, but the Ultra soon managed to chase off alien Valkie, and destroyed Samekujira with his Stormium Beam. The destruction of Samekujira also brought an end to the third age of monsters and with Valkie's appearence started the third age of aliens.
