* EnsembleDarkHorse: Every monster in the game has its fanbase, but Biollante is probably the prime example after being axed from appearing in ''Save The Earth''.
** The ''[[Film/GodzillaFinalWars Final Wars]]'' redesign of Gigan in ''Unleashed'' is definitely this.
* GameBreaker: Destroyah's Horn Katana in ''Unleashed'' can chop health bars to bits, especially the overhead swing.
** What makes it OP is that, unlike in the previous games, it costs ''no energy,'' so he can just spam it like Hell.
* ObviousBeta: While the game itself is complete, there were several elements in ''Unleashed'' that were unpolished, such as Godzilla 1954, and many of the features promised in the developer's diary went unimplemented due to lack of time and money.
* TheScrappy: [[OriginalGeneration Krystalak and Obsidius]] were not very well received by a large portion of the fandom, though Obsidius seems to have fared better.
* RescuedFromTheScrappyHeap: While not received very well in the similarly ill-received ''Film/GodzillaVsMegalon'', Jet Jaguar has since found redemption in the eyes of fans through ''Save the Earth'' and ''Unleashed'' where he is a very fun character to play as and has fared better overall.
* ScrappyMechanic: ''Unleashed'''s motion controls were... not well-received.
