Godzilla 1967 is not too bright. He has the mentality of a three year old. He is used by G#1.
He was first spotted when he broke into Zilla's house to steal some fish. He then was involved in many minor hi jinks from then on. He was captured by Spiga and cloned in the thousands, making an army of mindless drones. The army was defeated, and Orochi launched the souls of the clones into space! since they were so annoying. The original was taken by Orochi as a pet. Once Orochi died, 67 found himself on the planet of youth, where he ate fish all day. Once Lord Ghidorah entered the universe, 67 came up and tried to talk to him, but was murdered for his stupidity. His body was possessed by an unknown force as a portal back to this universe. The force left his body, and the body was destroyed by Bagorah in the Novaverse.
