With an endless amount of bizarre and unusual creatures, the Star Wars universe certainly has room for some of the more unusual Pokémon in the Pokédex. What makes the Star Wars universe a uniquely good fit for some of the wildlife from the Pokémon world is the different kinds of creatures it plays host to, alien, droid, or even something in between.
Similarly, Pokémon come in all different shapes and sizes and fit into the Star Wars universe in a variety of different ways. Some are more easily pictured on the bridge of the Death Star than fighting beside the Jedi, and some just seem like they'd make their own way in the galaxy.
Stoutland
The Star Wars world is full of old, wise, and slightly eccentric sages, and Stoutland would fit into this role very well. With its wild mane and long flowing mustache, Stoutland also fits in with the more hairy characters of Star Wars such as Chewbacca and even Obi-Wan in Attack of the Clones.
Stoutland is a Pokémon known for its wisdom, as well a habit of rescuing people who get stranded by blizzards. As such, it's easy to imagine it in the mentor role that Yoda, Obi-Wan, and even Luke take on in his own fashion in The Last Jedi, teaching important lessons to the inexperienced Rey. Gentle and noncombative, Stoutland is as peaceful as an old Jedi should be.
Beheeyem
With its elongated head shape, green eyes with black pupils, odd curves and accents, and colored lights rather than fingers, it would be hard to tell at first glance whether Beheeyem belonged in the category of alien or robot. Certainly, Beheeyem is a Pokémon with the appropriate weirdness to feature in the Star Wars Universe.
The psychic-type Pokémon uses the lights on its hands to communicate, not dissimilar to the combination of lights, beeps, and whistles that R2D2 employs in the films. Beheeyem looks like a creature that could be found in the far-flung corners of the galaxy, perhaps laying broken in a Jawan Sandcrawler, or serving drinks in Jabba's Palace.
Alakazam
The final form of Abra, Alakazam has an intimidating appearance with sharp claws for hands and feet, an aggressive-looking snout, and large horns. Whilst this alone would make it an interesting addition to the alien species in Star Wars, it is the creature's abilities that make it most suited for a galaxy far far away.
Alakazam's psychic powers could easily rival the abilities of some force-users, being one of the strongest Pokémon of the psychic type. The Pokémon even moves by manipulating its body with telekinesis. Alakazam sometimes closes its eyes during battle to heighten its other senses, similar to Jedi meditation techniques. Alakazam's power and mysterious nature would make it an interesting addition to the Star Wars universe. It is even said to have willed the spoons it carries in each hand into existence, a kind of power that has not really been explored in Star Wars.
Yamask
The world of Star Wars contains a variety of masked figures, both on the side of good and bad. Yamask has a unique look, not even wearing the mask over what would normally be considered to be its head, but with its creepy, non-humanoid form, the ghost-type Pokémon wouldn't look out of place among the bounty hunters of Star Wars.
Perhaps even more appropriately, Yamask evolves into Cofagrigus, a powerful four-armed Pokémon with a body of sparkling gold. Yamask would not be the only one in the Star Wars universe to multiply its limbs and step up its power when the situation requires.
Palossand
The Star Wars universe is known to hide powerful things in small and unlikely packages, making Palossand a perfect fit for it. Palossand looks relatively innocent, at least from a distance, where it resembles an ordinary sandcastle with a large door for a mouth. The dual-type ghost/ground Pokémon would have no problem blending into the desert environment of planets like Tatooine and Pasaana.
However, Palossand isn't something a wanderer would want to come across out in the galaxy, as the creature uses its disguise to curse people with whom it crosses paths and suck out their vitality. It is easy to imagine the creature representing another danger for lost rebel forces out in the wild.
Zekrom
A powerful legendary Pokémon with some of the best lore in Pokémon, Zekrom is a large and imposing dragon-like creature. Zekrom has a dark color scheme, an armored outer body, and red eyes with white irises and black pupils. This intimidating figure would perfectly suit the dark side of the force, whether as a leader or a powerful enforcer.
Zekrom is also a dual-type, with electric as its secondary, and as a result, the Pokémon can produce powerful lightning strikes to match the force lightning Palpatine and other members of the Sith employ. Zekrom assists those who wish to create an ideal world, so perhaps it would be a better match for the righteousness of the Jedi order. Either way, the dragon Pokémon would be a terrifying enemy for those on the opposing side.
Ursaring
Star Wars may already have its fair share of large bear-like creatures that walk around on two legs but this is all the more reason why Ursaring would fit in so well. In a world where Chewbacca is one of the rebellion's biggest allies, it is easy to envision the wider, squatter creature with a large ring pattern covering its chest giving its all in the fight against the Trade Federation, Empire, or First Order.
Ursaring is helped in any fight by its powerful physique and huge claws, and its climbing abilities and a thick coat of fur would allow it to traverse some of the harshest of environments. Ursaring also possesses a keen sense of smell that would help in skirmishes where knowing where the enemy is before they arrive could be crucial.
Pikachu
As BB8 and Ewoks have demonstrated, the world of Star Wars isn't afraid to use cuteness to hide potentially powerful allies. As the ultimate cutest Pokémon of all time, Pikachu is the perfect candidate to take on this kind of role in the Star Wars universe. Pikachu is also a Pokémon known for being uniquely loyal and empathetic once a bond has been established, meaning it would always be ready to back up its friends.
Pikachu is additionally perfectly suited for this due to the powerful punch the little electric Pokémon packs. When backed into a corner, Pikachu wouldn't be afraid to apply a swift Iron Tail and shock anyone who underestimated it.
Necrozma
A member of the Legendary Trio of Alola, Necrozma has a striking appearance full of spikes and sharp angles. The psychic Pokémon looks fully armored and has two giant claws that even on their own would be enough to render it a powerful figure in the Star Wars universe. However, rather than its claws, the main threat of this Pokémon comes from the powerful lasers it discharges.
Necrozma collects light to use as an energy source and lays in slumber underground, like the Sarlacc, ready to rise to the surface and make a lot of problems for whoever happened to be above it at the time. This is not a Pokémon anyone would want to encounter but for the same reason, it could make for some exciting scenarios in the Star Wars world.
Tentacruel
Tentacruel is one of the most alien-looking Pokémon, with bulbous red orbs on its head, sunken eyes, and a long snout. The Pokémon also possesses tentacles that it uses to immobilize and constrict its prey, surrounding them in a poisonous net. Tentacruel would be a good fit for the Star Wars universe which already possesses some interesting and dangerous aquatic species.
Occupying the ocean of the aquatic planets in Star Wars, Tentacruel would be feared by Jedi and Sith alike. The creature can also fire off ultrasonic waves to weaken its prey, which is signaled by the red orbs on its head lighting up. Among some of the other creepy and terrifying aliens in the Star Wars universe, Tentacruel would be a perfect addition.
