Monster Underground

Monster Underground is the eleventh episode of Godzilla: New Age of Monsters season 3.

Plot
The episode starts off with the Gammas saving the lives of citizens when an earthquake strikes in Tokyo with several buildings falling apart as Starman says that it's worst than having a giant monster attacking the city.

The captain of GUTS contact the Gammas and tells them that the earthquakes aren't just happened in Tokyo, but all over Japan. In the meantime, the culprits responsible for the disasters reveal themselves as the underground humans while they broadcast a televised message across the entire planet as they demand that the human race surrender and fall under their rule or they will create more earthquakes with an earthquake generator and that they send their monster Telesdon to attack the surface world as the Gammas must act fast to save Japan from the diabolic plan of the underground humans.

Tracey was able to locate the underground humans' lair in Mount Fuji as  Starman, Starwoman, Black Dragon, Akiko and Toby went there to destroy the earthquake generator. Meantime in Tokyo, Samantha and the others were fighting against Telesdon with the help of Zone Fighter who is having a hard time fighting the creature as Godzilla shows up on land while the half of the team battles the underground humans soldiers while Toby and Akiko manage to destroy the earthquake generator as Godzilla appears in Mount Fuji destroying their lair. As Starman tells everyone that they need to get away and back on the jet, the lair was collapsing, killing the underground humans and freeing Telesdon from their control which was easy for Zone Fighter to knock the monster down.
