LittleGodzilla

A year later, BabyGodzilla had taken up residence on Birth Island, where exposure to Godzilla's radiation had caused him to grow to 30 meters in height. Now known as LittleGodzilla, the young Godzillasaurus roamed the island freely, frequently following G-Force Major Akira Yuki, who was living on the island to observe Godzilla with the goal of killing him. Despite his hatred for Godzilla, Yuki had a soft spot for LittleGodzilla, who Yuki claimed was fond of him as well. When G-Force members Koji Shinjo and Kiyoshi Sato arrived on Birth Island along with Miki Saegusa, Susumu Okubo and Chinatsu Gondo to enact Project T, Yuki had tear gas mines planted along the shore. Unfortunately, LittleGodzilla set off the mines instead, and eventually ran off into the jungle. When the monster SpaceGodzilla landed on the island, LittleGodzilla approached him. SpaceGodzilla immediately attacked the young monster, causing his eyes to glow red in fear. As if sensing his adopted son was in danger, Godzilla came ashore and confronted SpaceGodzilla. LittleGodzilla cowered behind his father, who fired his atomic breath at SpaceGodzilla, who easily deflected it with a crystal shield. SpaceGodzilla knocked Godzilla down with his corona beam, then used his telekinesis to grab LittleGodzilla and trap him in a crystal prison. Godzilla got back to his feet and pursued SpaceGodzilla to Japan, intent on freeing LittleGodzilla.

After Godzilla defeated SpaceGodzilla with the assistance of MOGUERA, LittleGodzilla's crystal prison was destroyed, and the young monster began roaming Birth Island again and firing atomic bubbles from his mouth.
