To everyone marveling at how imaginative and wondrous all of Annihilation's fantastical, mutated creatures are, you realise they're all just Pokémon, right? We'll explain below - but it will involve a great number of spoilers for the film, so beware.
The vast majority of Alex Garland's Annihilation takes place within the Shimmer. It's a mysterious area around a lighthouse where an extraterrestrial being crashes and creates an expanding bubble in which the DNA of all organic things is refracted and remixed, causing spontaneous mutations.
The mutated creatures within the Shimmer are as beautiful as they are terrifying and dangerous, but what struck me most about seeing them in the movie is just how strikingly similar they are to a number of monsters from Nintendo's Pokémon franchise.

The Floral Deer
One of the first creatures biologist Lena (Natalie Portman) encounters during her expedition into the Shimmer is a pair of graceful, deer-like creatures whose exposure to the mutating bubble causes them to manifest flowers that grow from their antlers. These unnamed creatures closely resemble the Spring form of Sawsbuck, a fifth-generation Pokémon whose body transforms along with the seasons. In its Spring form, the Sawsbuck, like the monsters from Annihilation, grow clusters of pink flowers from their horns. You could also make the case that Annihilation's creatures were inspired by Xerneas, the fairy-type legendary from Pokémon X and Pokémon Y.

Unlike the peaceful deer monsters, the alligator creature the team encounters as they venture deeper into the Shimmer is openly hostile; it actually tries to kill physicist Josie Radek (Tessa Thompson).
When Lena discovers that the animal has concentric rows of serrated teeth like a shark, the team begins to realise there's way more to the Shimmer's strange creatures than meets the eye. Here, it becomes clear that whatever this thing is, it has more in common with a Feralgatr, the final evolutionary form of Pokémon Gold and Pokémon Silver's water starter Totodile. Presumably, the Shimmered gator, like Feraligatr, is a completely amphibious creature capable of breathing underwater and making deadly charges at prey while on land.

The Fungal Man
All of Annihilation's creatures are blends of organisms that wouldn't be able to crossbreed under normal circumstances, but one of the Shimmer's creations stands out as being particularly horrifying when we see it in its final form. Early in the film, the team stumbles across a video recording of the team that came before them, who ultimately either fell prey to the Shimmer's monsters or were mutated out of existence by it themselves.
In the video, you can see that a man's organs were at one point writhing around inside of him like large earthworms — and by the time the latest team finds his remains, what's left of his corpse has been transformed into a sprawling fungal growth that exploded from somewhere within his guts. It's a wee bit of a stretch, but this man calls to mind Foongus and Amoongus, two vaguely humanoid fungus Pokémon from the fifth generation.

The Florinic People
It goes without saying that almost everyone who ventures into the Shimmer doesn't end up making it out But some of the people who die within it are lucky enough to experience deaths that are peaceful. Josie is actually the first of the scientists to deduce that the Shimmer refracts living things' genetic code the way a prism refracts light. She comes to the conclusion after realising that a number of floral growths within the Shimmer appear to be shaped like human bodies, something she theorizes is the result of plant DNA being spliced with human hox genes, the genes that define the general body plan for multicellular organisms.
Rather than trying to escape the Shimmer, Josie chooses to become part of the new ecosystem and literally becomes a piece of living, human-shaped topiary — a being similar to a number of grass Pokémon, like Bellossom, Roselia, Roserade, and Florges.

The Skull Bear
Surveyor and geologist Cass Sheppard (Tuva Novotny) is the first member of the team to be killed by one of the Shimmer's creatures — a mutated bear with vicious fangs and the ability to mimic human voices. Well, one human voice, at least. There are quite a few bear Pokémon, like Teddiursa, Ursaring, Pancham, and Pangoro, but weirdly enough, Annihilation's demon-like bear creature has the most in common with Bewear, seventh generation normal/fighting dual type.
Like the Shimmered bear, Bewear is known for mimicking the behaviour of humans (though Bewears are known for waving like people and not speaking) and being incredibly dangerous creatures. A Bewear's warning is less of a greeting and more of a warning that they will crush you to death if you get too close. Annihilation's bear also has an exposed cranium reminiscent of the literal Marowak skulls that Cubone are most often seen wearing.

Lena makes it to the impact site where the being responsible for the Shimmer first landed, and by the end of the film she has a fascinating, confusing interaction with the alien. In Lena's opinion, there's a good chance that the Shimmer alien arrived on Earth not fully understanding where it was or what kind of influence it might have on the local wildlife. More than that, Lena theorizes that the alien might not have even fully understood what its very self was, something hinted at when the alien confusedly transforms itself into a replica of Lena before she tricks it into killing itself with a phosphorous grenade.
In many ways, the Shimmer and whole of Annihilation shares a number of similarities with Deoxys, the third generation Pokémon who stars in the seventh Pokémon movie Destiny Deoxys. Like Annihilation's alien, Deoxys is an extraterrestrial creature that first crash lands on earth only to be confused by its new surroundings, prompting it to project a luminous, multi-coloured light into the sky that acts as its form of communication.
Deoxys is also known as the DNA Pokémon because of the helix theme to its overall design and its ability to change its physical form at will in response to external stimuli. Like Annihilation's alien, Deoxys can be seen as a natural, powerful force that people perceive as dangerous because they don't fully understand what it is or what it wants. (As a number of people have accurately pointed out, the Shimmer alien also shares the Pokémon Ditto's ability to morph into other beings.)
Annihilation is almost certain to leave you with more questions than you had going into the movie, but the real takeaway from the movie is simple: As cool as Pokémon may be, actually living with them in the wild would be incredibly hazardous, and would require that all Pokémon trainers travel alongside groups of heavily-armed scientists.
