When looking at Pokémon's entire history, Water-types have been immensely popular. At this said time, there are 144 Water-type Pokémon, which makes it the most common of all. This has naturally allowed this type to have some truly iconic names within it. Some of these include Squirtle, Totodile, Suicine, and Blastoise, to name a few. Every time a new generation presents itself, there are a plethora of new Water-types.
Yet, even with all of this being the case, it is clear that not every Pokémon in it really is a perfect match. In fact, it's easy to argue that specific ones actually would have worked better if they were in a different type. Although this cannot happen at this said juncture, it is an interesting thing to think about. It just seems as though that some Pokémon actually look like they belong elsewhere. Even if some of them are strong options in battle because of their attacks, it is still hard to envision them as Water-types.
Wingull
Although Wingull is often around water-like settings, it is strange that it also a Water-type. When seeing as how it is clearly a seagull, it is not a creature that actually lives in the ocean.
Therefore, it is a little strange for it to have water abilities, to go along with it being a Flying-type. It is not the worst of cases, sure, but it is still a little out of left field for it to possess water attacks.
Marill
When looking at Marill, it is kind of hard to believe that it is a Water-type. However, it does hold this distinction, even though it does not necessarily resemble any sea creature out there.
Besides it possessing a blue color, it just seems as though it works better elsewhere. It being a Fairy-type does make a lot of sense, though, as it does have similar qualities to other Pokémon in this classification.
Kabuto
Kabuto is a Generation I Pokémon that gamers always should look out for, as it evolves into the ever so powerful Kabutops. Yet, even with this being the case, it is a bit weird that it is a Water-type Pokémon.
It possesses more qualities, in terms of its appearance, of one that would fit better as a Ground-type. Although they do inhabit water areas, it really does seem as though that they would have worked better in dry areas.
Greninja
Greninja is one of the most popular Pokémon from Generation VI, as it even is a usable character in the Super Smash Bros. series. As a Water-type, it actually does open the floor to friendly debate.
Although Greninja is blue in color, it also seems as though that it would have worked perfectly as a Fighting-type. With its combative nature, it certainly does resemble other Pokémon from this specific type.
Volcanion
Another Generation VI Pokémon, Volcanion is certainly one that possesses an immense amount of power. For casual followers of the series, it is very hard for them to remember that it is part Water-type.
It does make a ton of sense that it is a Fire-type, as it is red and orange in color. However, the water side of it seems a little bit out of place. It is easy to praise its originality, though.
Pelipper
Pelipper is another Flying-type that for some reason also has the Water-type label. It is the evolved form of Wingull, so it of course is inevitable, but it also does not seem like the correct fit.
In fact, Pelipper actually would have made more sense as a Normal-type, as it is almost identical to a real-life pelican. The series does this with other Pokémon who resemble animals significantly, too, such as with Tauros.
Bibarel
Bibarel is a Pokémon that not many players are desperately looking to obtain. That is not a knock on this lovable goofball, but it is apparent that it just does not do that well in battle.
It is understandably a Normal-type, but it is important to remember that it also is a Water-type, too. This is particularly strange because its previous form, Bidoof, actually is not. That alone makes it rather perplexing.
Palkia
Palkia is a Legendary Pokémon that makes its debut in Generation IV. It is certainly a breathtaking creature, but what is rather interesting about is the fact that it is actually a Water-type Pokémon.
It is understandable that this Legendary Pokémon is a dual-type, but based on its appearance, the water aspect of it just does not fit. It seems as though that it could have been an excellent choice as a Steel or even Fire-type.
Binacle
Binacle is a rather peculiar Pokémon based on appearance alone. Yet, what is even more intriguing about it is the fact that it is a Water-type. Nothing about necessarily gives off that vibe, but alas, it is the truth.
When seeing as how it is actually located on a rock, it would have made more sense for it to be that type. It does not necessarily look identical to barnacles, either, so they could have even gave it an entirely different name.
Wash Rotom
Wash Rotom is, well, different. It is a Pokémon that is based on a washing machine, so it does technically make sense as a Water-type. However, it is hard to understand how this concept even came to fruition.
Yet, the whole idea of Rotom changing into different household appliances is hard to completely jump on board with. It is a little bit comical, but this Pokémon just does not gel with the rest of the Water-types around it.
