Shelltar
Normally a peaceful creature living in the oceans off the coast of Japan, Shelltar was at bay eating fish like normal. That was until Z.A.T tried out a new missile in the water, right where Shelltar lived. Thinking the object was a massive fish, Shelltar caught it in his mouth, but it got caught between his teeth.
The creature bellowed in pain as he tried to remove it. Once that failed, the monster came on land, still trying to free it. Z.A.T was about to attack the creature until they saw what was stuck in his maw. They developed a new plan: help rid the creature of it. They used their massive jet and hook to grab on, but they accidentally grabbed one of its teeth. Kicking on the boosters of the jet, Z.A.T accidentally yanked one of its tooth out!. The beast bellowed in a mixture of pain and fury and attacked the humans below. Z.A.T attacked back, and Shelltar fled to the city where he was once more attacked. When everything else failed, Kohtaroh transformed himself into Ultraman Taroh.
The massive hero attacked the rampaging monster, but even his Storium Ray failed to destroy the creature. When Taroh managed to get Shelltar down, he wrapped several power lines around the creature’s maw. The beast howled in fury, but the electrical currents soon dissipated. Taroh eventually knocked the missile out of Shelltar's mouth with a kick to the back of the head, and as the missile flew back down, Z.A.T reactivated it and it flew forward, back into Shelltar's mouth. Before the creature could let out a cry, the missile detonated, showering the area with flaming pieces of Shelltar's flesh.
