Subtitle: Valley Monster (渓谷怪獣 Keikoku Kaijū)
Every hundred years, a monster was said to appear in the Kiya Valley's village. In that year, the village chief decided to use the legend as a tourist attraction strategy, placing fraudulent records of monster roars in various areas and even name it Cathy, after their own village. However, the real monster awoke.
When UGM attacked, they could not faze the creature with the weapons. However, they found that it would run out of energy if it did not eat meat. When it tried to eat two villagers, Takeshi transformed. 80 and the monster battled, while Cathy tried to eat the hero himself. Ultraman managed to defend himself until the monster collapsed from hunger.
80 then flew the monster to a place where it could return to sleep undisturbed.
- Kyasshi roar is a modified Gabara roar.
- Cathy uses a modified Crescent suit.
- Because of their uncanny resemblance (color and appearance), Cathy was compared by UGM members to Ghostron from Return of Ultraman. However, the episode exaggerated a few key features, including that Cathy being four times bigger and requires to eat 1000 kg meats to stay active.
- Cathy being used as an attraction by the village chief and its name may be a reference to the legend of the Loch Ness Monster, referred in the Japanese as Nessie (hence Cathy/Kiyasshi theme naming).
