The Second Generation Godzilla (二代目ゴジラ Nidaime Gojira) is a kaiju that first appeared in the 1955 film, Godzilla Raids Again. This Godzilla is the most prolific version of the character, appearing in 14 films and a television series. He appeared less than a year after the previous Godzilla's demise, again a prehistoric sea creature awakened from his ancient slumber by nuclear testing. While this Godzilla followed in his predecessor's destructive footsteps at first, he eventually fought on the side of the human race in Ghidorah, the Three-Headed Monster, where he joined forces with Mothra and Rodan to drive off the evil space monster King Ghidorah. Godzilla would go on to become a frequent defender of the Earth, rising whenever the planet's well-being was threatened by malevolent forces, whether they were other monsters or sinister alien races. Over time, Godzilla established himself as the undisputed King of the Monsters, gaining more allies like Anguirus and King Caesar. He also raised a son, Minilla, and trained him to take up his mantle. After slaying King Ghidorah at the end of the 20th century alongside six other monsters, then smashing the Kilaak aliens' secret base, Godzilla returned to Monsterland to live out the rest of his days in peace.
