If you’re intoGodzilla, as a series, then the announcement of any new film is obviously going to be worth celebrating. But if you’re really into the series, and have seen every film at least once (you know, all 40-ish of them), then the announcement of a new film is even more exciting. This is because it kicks off speculation about which monsters might appear, be they new ones entirely (as was seen with the villains inGodzilla x Kong: The New Empire), or fresh takes on already-established monsters from the series’ lengthy past (like inGodzilla: King of the Monsters). Or, admittedly, as has been the case with more recent JapaneseGodzillafilms (Shin GodzillaandGodzilla Minus One), there haven’t been other monsters beyond the titular one.
It’s safe to assume, though, thatGodzilla x Kong: Supernovawon’t justfeature Godzilla and King Kong, as evenGodzilla vs. Kongintroduced a new take on Mechagodzilla, despite that film’s focus being on the two main titans. So, this is a rundown made up of pure speculation. Based on the title “Supernova,” there’s a good chance the villain will come from outer space, andthe following monsters from the history of theGodzillaseries all originated in space, too. They’re ranked below, roughly based on how powerful they were, and thereby how much of a threat they could be if reintroduced into the series.

First appeared in ‘Godzilla 2000: Millennium’ (2009)
ThelastGodzillamovie of the 1990swas alsothe first of the Millennium era, and had the somewhat clunky title ofGodzilla 2000: Millennium. This one stands out against the films that kick-started the Showa and Heisei eras (GodzillaandThe Return of Godzilla, respectively), though, given that they just focused on humanity’s battle against Godzilla, while this 1999 movie gives Godzilla an equally large and monstrous foe to fight. That monster’s known as Orga, and he is essentially the mutated biomass of an alien race who crash-landed on Earth millions of years ago, and lay dormant for much of that time.
(Orga is) a monster that looks a little like Godzilla, and has some of his attributes, but is overall more mutated and not quite able to best him in combat, either.

Well, that biomass also took on some of Godzilla’s properties, but imperfectly, resulting in a monster that looks a little like Godzilla, and has some of his attributes, but is overall more mutated and not quite able to best him in combat, either.Orga is still a threat, though, and could’ve entirely assimilated Godzilla and perhaps continued to mutate had Godzilla not attacked Orga from the inside(Orga can heal fast on the outside, which made defeating him through more traditional methods difficult, if not impossible). Anyway, he’s kind of an underrated and lesser-known foe, so having theMonsterVerseput some kind of new spin on him might be neat.
Godzilla 2000
First appeared in ‘Godzilla vs. Gigan’ (1972)
Going back to the 1970s now, Gigan was a monster that initially showed up in, unsurprisingly,Godzilla vs. Gigan. That movie establishes his origins as being cosmic in nature, given he’s sent by an alien race (alongside King Ghidorah, who has already shown up in theMonsterVersein his most familiar form) to conquer Earth, so kind of typical stuff for the kaiju genre, and especially one from Godzilla’s Showa era. Even without knowing all that, it seems pretty clear that Gigan is not of this Earth, thanks to having a bizarre design and difficult-to-identify attributes.
Like, youcan look at Mothra and say, “Hey, she’s kind of a giant moth,” and you can do the same for something like Rodan, too (“giant pterosaur”). But Gigan’s got those weird claw arms, a beak, scales on parts of his body, and then a circular saw of some kind right on his chest, which is – perhaps naturally – used as a weapon. And that’sto say nothing of how he appeared inGodzilla: Final Wars, where his bladed hands/arms were replaced with chainsaws.He’s a fearsome foewho has, admittedly, yet to defeat Godzilla, even with Ghidorah’s help, but he’s wacky and weird enough to fit right in with the sort of thingtheMonsterVersehas been goingfor tonally so far.

Godzilla vs. Gigan
3SpaceGodzilla
First appeared in ‘Godzilla vs. SpaceGodzilla’ (1994)
SpaceGodzilla seems like the front-runner to appear inGodzilla x Kong: Supernova, going by discussions and speculation online, and sure, it would be cool to see him again. After all, it has been more than 30 years sinceGodzilla vs. SpaceGodzillacame out, andthe “space version” of Godzillahas not appeared in another feature film since. As mentioned before, the MonsterVerse has been getting progressively goofier and more over-the-top, to the point where now, the idea of throwing in a monster for Godzilla to fight who’s quite literally called “SpaceGodzilla” probably won’t be too much of a stretch for most viewers.
SpaceGodzilla is a little taller and also bulkier than regular Godzilla, and is a creature that evolved in space, as his name suggests, probably thanks to Godzilla’s cells going in and/or out of black and/or white holes. Something weird happened, and then SpaceGodzilla ended up back near Earth, and then the film he appears in has the kind of monster smackdown you’d expect it would.Godzilla vs. SpaceGodzillais agood, but certainly not great,Godzillafilm, so that might well make SpaceGodzilla a worthy opponent to reintroduce. There’s no legacy of a great film to trample on, and,if he was executed well, a second appearance might well even trump his first main appearance.

Godzilla vs. SpaceGodzilla
First appeared in ‘Godzilla vs. Hedorah’ (1971)
Truth be told, humanity is largely responsible for what Hedorah became, but his origins are nonetheless cosmic, so he can still be included here for present purposes. Hedorah was originally an alien life form that arrived on Earth in a comet,but became as threatening as he did because he fed on all the pollution around him, which is the humanity-made stuff. Maybe there’s pollution elsewhere in space, or maybe it’s always what this type of lifeform feeds on, butin any event, it spells disaster for humanity.
It even spells disaster for Godzilla for a little while, considering Hedorah’s unique abilities and near-invulnerability make him a tough opponent for Godzilla to best in combat. He’s a highlight of one oftheGodzillaseries’ strangest and darkest films, and you can go ahead and add “underrated” to the list of adjectives that can beused to describeGodzilla vs. Hedorah, too. Hedorah had a cameo of sorts inGodzilla: Final Wars, but is otherwise waiting for some kind of rematch. IfGodzilla x Kong: Supernovawas the movie to provide just that, hardcoreGodzillafans will probably be over the moon (say hi to SpaceGodzilla while you’re out/over there).

1Monster X / Keizer Ghidorah
First appeared in ‘Godzilla: Final Wars’ (2004)
So, as mentioned before,King Ghidorah has shown upin theMonsterVersealready, but there’s a particular variation of Ghidorah that hasn’t… kind of. Ghidorah is technically the final villain inGodzilla: Final Wars, initially known as Monster X but eventually emerging as – and revealing himself to be – Keizer Ghidorah. You get two monsters for the price of one, and something that feels different enough from regular Ghidorah to count as his own thing. And, hey, theMonsterVersehas already gotten ridiculous, so would introducing a new type of Ghidorah really be all that wild?
It would also be theleast predictable option, given the speculation surrounding Gigan, SpaceGodzilla, and Hedorah already.Godzilla: Final Warsis the mostbombastic (and possibly the most divisive)Godzillafilm, so maybe calling back to it would be seen as best avoided. Though, on the other hand,Final Warsis gonzo, and so havethe last couple ofMonsterVerseGodzillamovies, so you could also argue that the madness should continue, and noGodzillafilm has been weirder, sillier, and more over-the-top thanGodzilla: Final Wars.
