- Designated Hero: Really, the entire conflict of the movie is pretty much Joe's fault, as he doublecrosses the Irish in order to steal Gorgo for himself and use him as a circus attraction to strike it rich. Sam is a lesser example, as while he doesn't bat an eye to Joe's plan to doublecross the Irish, he does object to Joe's more sleazier actions such as trying to abandon Shaun and later insisting that Gorgo be kept locked up even when they learn that his mother is on her way. He's also generally far more pleasant and moral than Joe, especially towards Shaun.
- Fan Nickname: Gorgo's mother is sometimes called "Ogra" (though it's pronounced "Oogra") after the mythic name for the beast mentioned at the start of the movie.
- Ho Yay: Sam and Joe.
- Just Here For Gorgo: This was definitely Mike and the Bots' reaction.
- Visual Effects of Awesome/Special Effect Failure: While the effects were miles beyond anything that Toho made up to that point, YMMV on how it holds up today.
