The Gammas quickly went to the science center as they see that the newly hatched creature is a baby Godzillasaurus and that it's the biological offspring of Godzilla and was confirmed to be a male. They all seem to know that the baby is very friendly to humans unlike his father. Also, a group of bandits arrived to steal the baby Godzilla for ransom. After they trap the Gammas and the scientist, they kidnap the baby Godzilla as they made a big mistake. The young creature used his telepathy to call Godzilla as the mutant dinosaur appears in Tokyo for the baby's rescue. While the Gammas began to free  themselves and the scientists as they start to save the little one, just before Tracey has confirmed that Godzilla is in the city. Starwoman manage to stop the bandits' truck and forces them to hand over the baby Godzilla.
