Godzilla: King of the Monsters' Monarch website may have brought the Loch Ness Monster into the MonsterVerse. Legendary/Warner Bros. shared universe based on iconic Toho creatures, the MonsterVerse is currently building towards Godzilla vs. Kong, although it could go much bigger than that.
So far, three new monsters are teased to appear in Godzilla 2: Ghidorah, Rodan and Mothra. However, they're not the only creatures out there. Indeed, while the Monarch website promoting the film puts the spotlight on the resting places for the core four, there are a dozen other classified research stations around the globe that point towards other beings from the Toho canon.
Perhaps the most interesting, given how its legend reaches far beyond even that of Godzilla himself, is the Loch Ness Monster. One of the classified Monarch outposts is in Northern Scotland, right over Loch Ness (hat tip to Dread Central). The suggestion would be that, in the world of the new Godzilla movies, Monarch has identified it as a place of interest thanks to the repeated sightings of a water monster.
While this may make Nessie part of the extended MonsterVerse, it doesn't necessarily mean we'll be getting her in the movies any time soon. There's a lot of flagged locations on the Monarch website, none of which have official endorsement from the filmmakers themselves. However, like the similarly tease-laden S.H.I.E.L.D. map Iron Man 2, which featured character clues for Thor, Captain America, Black Panther and Namor, some of what's here could come to pass down the line.
If the Loch Ness Monster does come to the MonsterVerse at any point, it wouldn't be the first time she's been integrated into a Godzilla project. Godzilla: The Series, an animated spinoff of Roland Emmerich's 1998 reboot, featured an episode where H.E.A.T. and 'Zilla worked together with Nessie to save her young. Earlier, back in the mid-1970s, Toho looked to co-produce a Loch Ness kaiju film with legendary horror studio Hammer, but this never got out of early development due to the latter's money troubles.
It's also worth adding the theory that, should the Loch Ness Monster be used in any future Godzilla films, it could be as a myth surrounding underwater beast Manda, a recurring Toho monster. This would be more in-line with how Legendary is bringing the likes of Mothra and Ghidorah to the big screen, and would avoid the innate ridiculousness of making Nessie into a big screen kaiju. Whatever's coming, we're sure to get more evidence of the scope of the MonsterVerse's future when the Titans' secrets are revealed in Godzilla: King of the Monsters next year.
