The 10 Biggest Pokémon Ever (From Smallest To Largest)

When people see the designs of Pokémon, they often imagine them being very large. The truth is that when you look at the sizes of Pokémon in the Pokédex, you may be surprised to discover that a lot of them are not as big as you may think. The anime takes its liberties with some of the sizes, so the games sometimes surprise us when we see that Groudon is only 11 feet tall.

Here we have listed ten of the largest Pokémon based on their height in the Pokédex, from smallest to the largest of them all.

10 Giratina (14 Feet)

The smallest out of our largest list is the Ghost/Dragon legendary Giratina. It is a Pokémon that is epic on many scales, as it is a legendary that represents death and antimatter and it lives in the Distortion World. Among all legendary Pokémon, Giratina may not be the biggest, but it is definitely the most edgy. It is only the only Ghost/Dragon type to exist so far.

While it has other forms, its base form is still the largest.

9 Milotic (20 Feet)

Coming six feet above Giratina is the beautiful Milotic It comes from the humble beginnings of a Feebas and evolves to be even taller than the legendary Pokémon of antimatter! While it is a big Pokémon, it is known to be gentle and try to calm people's feelings.

While it is not legendary, Milotic is a difficult Pokémon to raise. You need to basically jam beauty pills into or groom Feebas until its pretty enough to evolve. Milotic is sort of a counterpart Pokémon to Gyarados.

8 Hoopa Unbound (21 Feet)

Just one foot above Milotic is the legendary Hoopa. However, it is only bigger in its unbound form. In the games, trainers have only been able to get Hoopa through hacking or by event.

Some other interesting facts about Hoopa Unbound include that it has the highest base Special Attack of all Dark-Type Pokémon. In terms of base Special Defense, it is tied with Mega Gyarados and Umbreon for the highest.

7 Mega Gyarados (21 Feet)

Tied with Unbound Hoopa's height is Mega Gyarados. Unlike Milotic, it is not a calm Pokémon. In fact, its entry in Pokémon Sun reads "Mega Evolution also affects its brain, leaving no other function except its destructive instinct to burn everything to cinders." So not only is it big, but it has a dangerous personality to match.

6 Rayquaza (23 Feet)

Two feet over Mega Gyarados and Unbound Hoopa is the legendary Dragon/Flying-Type, Rayquaza. It is part of the legendary weather trio from the Ruby and Sapphire games. In the Alpha and Omega games, Rayquaza plays an important role in the plot and you are required to catch it to fight Deoxys. Deoxys is only five feet tall, so Rayquaza definitely has that other legendary beat in terms of size. Yes, there are humans taller than Deoxys!

Maybe Rayquaza was not always large though, as its Pokédex entry claims that it is hundred of millions of years old. That may mean it was smaller way long ago.

5 Onix (28 Feet)

Beating Rayquaza by five feet is a pretty common Rock/Ground-Type Pokémon, Onix. They certainly look large in the anime! They have been around since the earliest games so they once held the title of largest Pokémon. However, times change and new Pokémon have taken its place as the largest.

They are neither legendary nor are they an evolution of any smaller Pokémon like others on this list. That makes their huge size special under those circumstances. We definitely would not want to make one of these huge rock monsters mad.

4 Celesteela (30 Feet)

Celesteela is an Ultra Beast from the Sun and Moon generation and stands as the largest of the Ultra Beasts. It is a Steel/Flying-Type and looks kind of like a spaceship. That wound make sense since it is said to be an alien from its Ultra Moon Pokédex entry.

Not only is it one of the tallest Pokémon, but it is also one of the heaviest. It ties with Cosmoem as it weighs over 2,200 pounds. That is two times has heavy as a grand piano.

3 Primal Kyogre (32 Feet)

Kyogre is the last legendary to make it onto this list, so it can be called the largest of the legendaries . . . but still not the biggest of them all. It sits with Groudon and Rayquaza as part of the weather trio in the Sapphire, Ruby, and Emerald games. Since Kyogre has the ability to expand oceans, it is to be expected for it to be a huge Pokémon. After all, the ocean takes up most of Earth so it probably also does in the Pokémon world (much to Team Magma's dismay). Kyogre also as a design that is similar to a whale, and whales are known to be massive.

2 Mega Steelix (34 Feet)

With Onix making the list, of course its evolution comes in as the second largest Pokémon of all. Onix evolves to Steelix and Mega Steelix is six feet higher than Onix. While it is not the tallest Pokémon, it is the tallest of both the Steel-Types and Ground-Types

Some other facts about Mega Steelix include that it is tied with Shuckle and Mega Aggron for having the highest Defense stat of all Pokémon.

1 Wailord (47 Feet)

It should come as no surprise that Wailord is the largest Pokémon of all. It is based on the largest animal on our planet, the blue whale. Almost every Pokédex entry also notes its large size. In Moon, its entry says that its size is its reason for popularity. Omega Ruby, Y, Black, White, Diamond, Pearl, Heartgold, and Soulsilver entries all stat that Wailord is the biggest of all Pokémon identified up till now.

Besides being the largest, Wailord has the highest base HP stat of any Water-Type Pokémon. Amusingly, in Pokémon Ranger: Shadows of Almia, it is a Pokémon you cannot capture because it is too big. It was even so big that it had to be resized for games like Pokémon XD: Gale of Darkness and Pokémon Colisseum.
