MINYA
Monster Island's Decisive Battle: Godzilla's Son (1967)
Destroy All Monsters (1968)
Godzilla-Minya-Gabara: Great Charge of All Monsters (1969)
Minya was Gojira's son,
hatched in the movie Monster Island's Decisive Battle: Godzilla's Son [aka "Son of Godzilla"]
Minya's home was not a safe place. There were many dangers, from giant mantis (Gimantis) to giant spiders.
Minya like his father had radiactive breath, though he normally could only manage smoke like rings, when his father stepped on his foot Minya could give off a long stream.
Afraid of Minya and his father the humans froze them at the end of Monster Island's Decisive Battle: Godzilla's Son. Father and son thawed out soon however.
Like any child Minya was usually afraid of the other monsters. He was bullied by Gabera in Godzilla-Minya-Gabara: Great Charge of All Monsters [aka "Revenge of Godzilla"]. However in Destroy All Monsters he was brave enough to take on King Ghidora!
