A monster from Atlantis rises from the sea and threatens to destroy the continent. So, humans scare him back under water with a giant robot.
In this issue, he’s called Goliath, but in 1971, when Marvel reprints the story, his name is changed to Gigantus…
The character will then appear in Fantastic Foure #347…
where he will be explained as a Deviant–but that hasn’t happened yet.
