* EnsembleDarkHorse: Mechagodzilla. While this film and its sequel weren't the most successful entries in the franchise, it proved extremely popular and managed to be the only monster besides Gigan and King Ghidorah to appear in another film, and became Godzilla's most popular enemy behind King Ghidorah.
* FridgeLogic: Japan's a series of small islands that are already seriously overcrowded in spots. Why not try to move into, say, Russia or Africa?
* SurprisinglyImprovedSequel: While opinions on the overall quality vary, it's still generally considered an improvement over ''Film/GodzillaVsMegalon''.
* UglyCute: Mechagodzilla in his first form. Even his roar counts.
