The new trailer for newest trailer for Alien: Earth showed the first actual footage of the prequel series and had some major reveals about its story. The trailer showed a ship crash-landing on Earth, and one character was heard mentioning that it was carrying five different lifeforms, one of which is obviously the Xenomorph. Alien: Earth is also going to explore a hybrid version of a synthetic crossed with a human, and it should have many other thrills and surprises in store.

Alien: Earth's new trailer provided a lot of information about the show, and we can piece it together with some other reveals we've already gotten. Some of Alien: Earth's plot details have been shared, and the synopsis shows that the city the spaceship crashes into is owned by another mega-corporation known as Prodigy. We also know that Prodigy sends Wendy (Sydney Chandler), a human-synthetic hybrid, into the ship to investigate. The trailer, however, also included one massive new reveal that could change the entire Alien franchise forever.

Alien: Earth Is The Franchise's First Standalone Project With The Main Characters Battling Multiple Lifeforms (Not Just Xenomorphs)

Alien Vs. Predator Introduced New Lifeforms, But The Main Alien Franchise Has Dealt Exclusively With Xenomorphs So Far

In different types of Xenomorphs at various stages of their life cycles, and David (Michael Fassbender) did create his own variant in Alien: Covenant, but they're all the same species. As the "five different lifeforms" line indicates, Alien: Earth will be the first time the main Alien franchise has pitted its main characters against something other than Xenomorphs. The Xenomorphs will certainly be a factor, but the humans and synthetics in the show will have much more on their plates than normal.

This technically isn't the first time humans in the Alien franchise have fought something other than Xenomorphs (or the Engineers). In the Alien vs. Predator movies, humans also fight the Yautja, the titular aliens from the Predator franchise. However, Alien vs. Predator is dubiously canon at best, and it's certainly not part of the main Alien franchise, so Alien: Earth will be the first time something other than a Xenomorph or a synthetic is the main villain of the story. That's a huge milestone for Alien as a franchise, and it has some major implications for Alien: Earth.

Alien: Earth's Multiple Lifeforms Makes The Scale Of The Show's Horror Even Bigger

We Have No Idea How Alien: Earth's Other Lifeforms Will Behave Or Be Defeated

The biggest impact the different species in the Alien: Earth trailer have on the show is the sheer scale they're bringing. In most of the Alien movies, a considerable amount of time is devoted to finding the Xenomorph, uncovering its weaknesses, and then using them to kill it. Alien: Earth's main characters will have to do that too, as they've never encountered a Xenomorph before, but they'll also have to do it with four other presumably hostile aliens. Tangling with a Xenomorph was tough enough on its own, but Alien: Earth has quadrupled the stakes with its new species.

The new species will impact Alien: Earth's plot, but it should also impact its viewers. After eight movies and nearly half a century, we know what to expect out of Xenomorphs and how to fight them. Movies like Alien: Romulus can still pleasantly surprise us with things like the Offspring, but for the most part, the formula is largely the same. Alien: Earth's new species will bring with them new tactics, weaknesses, and ways to horrify viewers simply by virtue of never being seen before. We have no idea how these new aliens operate, so everything they do is a chance to deliver thrills and frights.

Alien: Earth's "Five Different Lifeforms" Can Completely Change The Franchise's Future

Future Alien Projects Can Pick From A Wide Variety Of Alien Threats & Even Introduce New Ones

The new species in Alien: Earth aren't just the biggest expansion of the franchise we've seen so far, they're also the key to changing the future of Alien forever. Now that Earth has introduced new aliens separate from the Xenomorphs, any future Alien project can turn to one of them as its main villains. We may one day get an Alien film that's solely about the squid creatures in Alien: Earth, or we may see any other combination of those aliens in tandem with the Xenomorphs. Because of Earth, the Alien franchise is no longer tied specifically to the Xenomorphs alone.

Alien won't even be limited to the species introduced in Alien: Earth either. If Alien: Earth proves that audiences are open to the idea of new hostile alien species, there's nothing to say that future Alien movies couldn't introduce even more new aliens. Future movies and shows could follow explorers heading to uncharted parts of space and finding new species, just like Ripley and the crew of the Nostromo found the Xenomorphs in the original Alien. In short, Alien: Earth may have just made the Alien franchise exponentially bigger.
