Underground Go! Go! Go! (地底GO! GO! GO! Chitei Gō! Gō! Gō!) is the 17th episode of Ultraseven.


A cave-in traps Jiro, a miner, 3,000 feet below the Earth's surface. The Ultra Guard is asked to help in learning of the cause of the disruption inside the cave. Referred to as the "Miracle Man", the Ultra Garrison learn that Jiro had previously survived a fall from a 700 foot cliff! Moroboshi senses something unusual while in the cave. Upon descending further, Dan learns just who Jiro is -- he's his other self; the human form Ultraseven rescued from the mountain fall before he copied his human form. Using a drilling attack vehicle called the Magma-lizer, the Ultra Guard dig through the rock to find Jiro before the confined area fills up with gas. Trapped beneath the Earth, the Ultra Guard discover an advanced civilization buried inside the rocks below.
