The Pokémon franchise is going strong for nearly 25 years. That's a quarter century of new pocket monsters, adventures, and updates. The series is constantly evolving like its namesake creatures. That also includes adding new Pokémon each generation. Occasionally, an entire new evolution will be added to an existing Pokémon or evolutionary line, which is exciting for fans.
Fans are always clamoring for a new form or version of their absolute favorites. With Dynamax, Gigantamax, regional variants, and Mega Evolutions in the games, fans have been able to see their favorites in all-new ways. Still, there are some Pokémon that never get these updates, or some that could still use some more.
Dhelmise
This Ghost/Grass anchor is known as the Sea Creeper Pokémon. It was added in Generation VII, a perfect aquatic addition to the Alola region in the Sun and Moon games. It is a huge anchor held to a ship's steering wheel by seaweed. This Pokémon not only has a neat design, but it's also the only one that can learn the move Anchor Shot.
Dhelmise absolutely deserves an evolution, as it cannot evolve into any other Pokémon. Speculating on what an evolution could look like for this cool creature, it could possibly evolve into a large ghost ship itself, or even a giant sail. Fans would love a new design.
Absol
Absol is one of the series' most popular Pokémon. This Dark-type Pokémon has been around since Generation III, where it captured hearts with its stand-out design. Although not one of the most powerful Pokémon, it is one of the most memorable. It's so popular, in fact, that it is one of the few to be given a Mega form.
Somehow, it still doesn't have an evolution, though. Absol would be a prime candidate to get a new Pokémon in its line, given its fan-favorite status. Simply imagine how cute an emo kitten would be as a predecessor, or to see it evolve into an even more ferocious feline.
Heatmoor
The Fire-type anteater Pokémon from Generation V onward doesn't have an evolution. This is surprising, as it is has made cameos in the anime, manga, and many side games in the franchise. It's about time an evolution gets added to its line.
Fun fact: Heatmor is the only non-Bug type Pokémon that can learn the move Bug Bite. This could be a clue as to what the anteater can evolve into: a Fire/Bug Pokémon. Not many Pokémon have the distinction of this specific, opposing dual typing, so it would make for a great final evolution for Heatmor.
Pinsir
Pinsir is one of the original Pokémon, with its origins going all the way back to good old Generation I. Beginning in Red and Blue, trainers could catch Pinsir in a couple of ways. Depending on the game, players could obtain Pinsir through trade, the Safari Zone, or Celadon City's Game Corner.
That made it exclusive and desirable. It also had a companion, as many do: Scyther, which got its own evolution in a later game. So why shouldn't Pinsir? It has a Mega Evolution form, but not a standard evolution. Maybe this will change in a later generation.
Girafarig
This cute giraffe Pokémon goes way back: first introduced in Generation II, Girafarig is Normal/Psychic and has no known evolutions. While not necessarily a fan favorite, it's about time such a sweet Pokémon gets its dues.
Think of how adorable an evolution would be. It could grow into a tall, long-necked giraffe, much like Alolan Executor. Or, its design could be similar to the dinosaur-like Tropius from Generation III.
Stantler
Stantler is another Generation II Pokémon with no evolutions. The Big Horn Pokémon is all kinds of classic: its design is a straightforward caribou while its type is simply Normal. Therefore, it provides a great foundation for an evolutionary line, but it never got the distinction.
Fans would probably adore a pre-evolution that looks like Bambi. It would serve the Pokémon well and make Stantler a desirable final evolution for players to reach. Maybe it will be chosen for a future evolution in another game, although it was introduced so long ago it's possible it will never get another form.
Maractus
Maractus the flowering cactus Pokémon has such a unique design that it's a shame it has no known evolutions. With the popularity of desert plants like succulents these days, which are all the rage with younger generations, it would be the cutest design to have a succulent Pokémon evolve into Maractus.
On the other hand, Maractus could also evolve into a larger and even more powerful Pokémon, such as a large plant, like a Joshua Tree or Yucca. That would serve its unique design well and really add to the Pokémon universe.
Klefki
Klefki is the cute Steel/Fairy-type Pokémon introduced in Generation VI. The Key Ring Pokémon has a one-of-a-kind look. But without any evolutions, it leaves so much to be desired. The possibilities are endless with this one! With the key motif, there are so many designs to play off of.
Here are a few to get the conversation started: it could evolve into a skeleton key, playing off its spooky look; it could evolve from a little lock with a heart-shaped key in honor of being Fairy; or it could start off as one of the keys on its keyring, similar to the evolutionary line of Dreepy.
Druddigon
Without contest, Druddigon is one of the coolest Pokémon from Generation V. But in a huge surprise, it doesn't actually have any evolutionary forms. Typically, Dragon-type Pokémon do have evolutions, as they usually appear later in the game and take quite a bit of leveling up to get to its final form.
Therefore, it would make sense for Druddigon to have one, if not two, forms to precede its final evolution. All the great Dragon types have them, as they are meant to be challenging to raise and train. Only a few generations old, there's a possibility Druddigon's line could expand.
Eevee
If there is any Pokémon most famous for its evolutions, it has to be Eevee. Its name even sounds like evolution, which is most likely intentional. The fox Pokémon is one of the most adorable and acclaimed designs, even getting its own feature in the Let's Go series.
Without fail, fans clamor for a new Eevolution with every generation that's announced. Interestingly enough, it did not get a new elemental evolution in the latest generation, but there are still so many possibilities out there: Ghost, Poison, Flying, and Dragon, to name a few. Game Freak simply has to continue expanding this line, there's no doubt about it.
