Pokémon and Mega Evolutions
Who doesn't love collecting and battling Pokémon? These mystical creatures range from cute to creepy to fierce. Formerly each Pokémon tree could have a maximum of three evolutions (with the exceptions of branching-evolutions, like Eevee).
But with Mega evolutions, Alolan forms, and other tricks, Pokémon are coming in more shapes and sizes than ever before. Today we'll explore the ten tallest monsters (excluding Gigantamax forms)—which do you think is biggest? Keep reading to find out!
10. Ultra Necrozma
Size: 24 feet 7 inches/ 7.5 meters
Necrozma debuted in Ultra Sun and Ultra Moon, and of his four forms, his Ultra mode is probably his best. Standing over four times as tall as myself, Ultra Necrozma carries a whopping 754 stat total and the deadly Neuroforce ability (increasing the power of his super-effective moves).
While I prefer the typing of his Dawn Wings (Psychic/Ghost) and Dusk Mane (Psychic/Steel) forms, there's no denying Ultra Necrozma's unrivaled power.
9. Wishiwashi (School Form)
Size: 26'11'' / 8.2 meters
In his normal mode, pipsqueak Wishiwashi is only eight inches big. But his schooling ability transforms him into hs School Form as long as he's at least level 20 and has over 25% HP remaining. This mode skyrockets every one of his stats except HP and speed, offering a fierce leviathan who can both tank and deal hits.
Size: 28'10'' / 8.8 meters
Early Pokémon fans have to remember this guy. Onix was the tallest original Pokémon, and anime protagonist Brock used one.

Onix towers over most others, measuring almost six feet taller than Rayquaza. He's noted for being able to travel over fifty miles per hour—while underground! However, as impressive as Onix is, he can turn into something even larger . . .
Size: 30'2'' / 9.2 meters
Type: Steel/Ground (Steelix), Steel/Flying (Celesteela)
Shedding Onix's Rock type for Steel, Steelix gains power and loses several elemental weaknesses. The PokéDex tells us Onix changes into Steelix when it lives past the age of 100, and its rocks are tempered into diamonds. I could have sworn you just needed to trade one holding a Metal Coat . . . ah, I must be crazy.
Meanwhile, Celesteela is arguably the strongest of the Ultra Beasts, with impressive stats and her Flying type removing Steel's regular weakness to Ground.
6. Primal Kyogre
Size: 32'1'' / 9.8 meters
In Pokémon Alpha Sapphire, the legendary Kyogre gained a new form: Primal Kyogre. Primal Kyogre is the heaviest, strongest, and arguably best Water Pokémon yet, and his new Primordial Sea Pokémon ability boosts the power Water attacks while automatically negating Fire. Be sure to stay on the good side of this mighty behemoth.
5. Mega Steelix
Size: 34'5'' / 10.5 meters
When Steelix unleashes his Mega form, he doesn't gain a new element, but becomes even more powerful. His defense skyrockets to new heights (literally), and he gains some mysterious markings across its body.
If you prefer gold over silver, catch a rare "shiny" Steelix to train a brighter version of this gigantic titan. Good luck cosplaying this one, Pokéfans.
4. Mega Rayquaza
Size: 35'5'' / 10.8 meters
As Rayquaza feeds on meteorites in our atmosphere, he slowly stores power, eventually turning into the formidable Mega Rayquaza. This form ravages foes with high offensive power, speed, and the fierce Delta Steam ability (his defenses are a bit lower though). Still, you know this monster is strong—in the anime, he defeated Mega Charizard X and Mega Metagross at the same time!
3. Alolan Exeggutor
Size: 35'9'' / 10.9 meters
Regular Exeggutor is a Grass/Psychic type that stands at a normal 6'7'', but in the Alola region, Exeggcute instead evolves into this gigantic plant. Alolan Exeggutor's frisk ability lets him see opposing held items, and he's a powerful albeit slow sweeper with good attack and special attack. Just watch out for his quad weakness to Ice.
Size: 47'7'' / 14.5 meters
I mentioned earlier that Primal Kyogre is the heaviest Water-type. That's certainly true, but he's not the biggest; a title that goes to whale-like Wailord. This creature dwarfs most others, being over 10 feet longer than Mega Rayquaza, but for such a massive Pokémon, his weight is oddly low: Wailord weighs less than 900 pounds. All that swimming keeps him trim, I suppose.
This is likely because Wailord's body is partially composed of air; he is, after all, the "float whale" Pokémon. But despite its low weight, none can deny Wailord's awesome size. I'd love to see him mega evolve into something bigger one day, but for now, the crown goes to...
Size: 65'7'' / 20 meters
Introduced in generation 8 games Sword and Shield, Eternatus and his Eternamax form stand at a dominating 65½ feet! He's connected to the Dynamax phenomenon (which can make any Pokémon big in certain places), and his 690 stat total is amazing, especially for a non-Mega legendary.
Emphasizing HP, special attack, and speed, Eternatus undoubtedly offers one Pokémon's best indirect sweepers (funny a Pokémon so big prefers to attack from range).
More of the Biggest Pokémon
Hopefully you've enjoyed reviewing some colossal creatures; I'm excited to see more large behemoths in Pokémon's future. We went by game data today, but we've also seen some oddly large creatures in the anime, like the giant Dragonite in season 1.
But for now, as we await more Pokémon giants, vote for your favorite and I'll see you at our next gaming countdown!
Questions & Answers
Question: What is the smallest Pokemon?
Answer: Several Pokemon tie for the smallest Pokemon. Check out a full list at the link below!
Question: Wouldn't Celesteela be on this list of top 10 largest Pokemon?
Answer: Yes, but this list predated Sun and Moon where Celesteela was introduced. That's the problem with reviewing ongoing games/media: new content released after a released article may change the article's accuracy.
Still, I enjoy covering Pokemon, and at some point in the future, I'll try to make an updated list.
Question: Is there a Pokémon bigger than Wailord?
Answer: Sort of. Alolan Exeggutor is now technically the biggest Pokemon, but because it's just tall and doesn't have much girth, you could still think of Wailord as the overall heftiest.
Question: What about Snorlax as the largest Pokemon?
Answer: You're probably thinking of weight, not height or length.The average Snorlax is 6'11'', which is taller than most humans, but nowhere near the size of Gyarados and the like.
Question: Is Snorlax the fattest Pokemon?
Answer: He might be the chubbiest, but he's nowhere near heaviest, with creatures like Celesteela and Groudon far outweighing him.
Question: What is the fastest Pokemon?
Answer: Speed Forme Deoxys. Feel free to check out my countdown on them!
Question: Regigigas is literally called the colossal Pokemon, why isn’t it on this list?
Answer: "Colossal" or not, Regigigas stands at 3.7 meters, barely over half the size of today's smallest entry, Gyarados.
Question: How tall is Magikarp?
Answer: 2 feet 11 inches, or 0.9 meters.
Question: Isn't Dragonite the tallest Pokemon in the anime?
Answer: Sort of. His silhouette in the season 1 episode "Mystery at the Lighthouse" (which featured video game character Bill) was definitely huge, but in future anime appearances, he was only a bit taller than an average man. And remember that anime heights greatly differ from official video game stats.
Question: Shouldn't Primal Groudon be number 1?
Answer: No, you're thinking in anime terms where Pokemon are often made bigger than they really are in the games. Primal Groudon isn't short, at 16'05", but it definitely isn't the tallest.
Question: Why didn't you include Primal Groudon as one of the largest Pokémon?
Answer: Because he's simply not as tall. Groudon does get bigger in his primal form, but even then, he's still standing at 5 meters, well under Gyarados's height stat.
Question: Which is the tallest Pokemon that can stand on its two legs?
Answer: Alolan Exeggutor (which also happens to be the new tallest Pokemon). Interestingly, unlike the Grass/Psychic regular Exeggutor, the Alolan version is a rare Grass/Dragon mix.

I think I adore Kyogre it's soooo cool specially Primal Kyogre. I'm kinda biased to Hoenn legends even though my favourite region is Kalos.
Jeremy Gill (author) from Louisiana on December 16, 2019:
Groudon is actually just 11'06" (or 16'05" as Primal Groudon), but the anime tends to exaggerate height.
Doritoman on December 14, 2019:
Dude what about Groudon I’m pretty sure he’s bigger than any other Pokémon correct me if I’m wrong
The Soup on November 24, 2019:
a new legendary for sword and shield is 65'7'' Tall
the master on April 08, 2019:
What about tyrantrum and guzzlord and the regi trio
Pikachuuuuuuuuuu!!!!!! on June 20, 2018:
Shut up neon. I don't even care about big Pokemon. I just care about chespin.........
matthew on May 29, 2018:
What about the colossal Pokémon regigigas?
master on April 29, 2018:
what about the regis
Neon on April 26, 2018:
Man, reading the comments is kinda sad. No one knows what they're talking about and all the pokemon they're listing are STILL smaller than Wailord haha And no one can even check the date of the article before asking about newer pokemon. But whatever, good article Jeremy
Macx on April 17, 2018:
How about Celesteela?
Mystery on March 29, 2018:
I thought Giratina was bigger than onix, and without the mega evolutions, groudon, dialga should be in this list
Jaskaran singh on March 26, 2018:
Wailord might be the biggest but it's not the strongest .The most powerful Pokemon is tied by three Pokemons and they are Mega Rayquaza and both Mega Mewtwo Y and X.
Trishit Lamsal on March 19, 2018:
What about snorlax?
DaPokemonMaster on February 27, 2018:
Isn't alolan exeggutor taller? He's a literal ginormous polm tree
Unown on February 17, 2018:
Yeah... caterpillar is the tallest at 1”0 (He sarcastically said)
DolphindreamerYT on February 17, 2018:
You forgot caterpie... BRUH
Anonymous on January 03, 2018:
Wailord is biggest, but not the strongest. Mega Rayquaza is the strongest because is an attack of 300 and is enough to knock out any other Pokemon.
anonmous on January 01, 2018:
Rando on December 24, 2017:
Just imagine a Mega Wailord
jack on December 01, 2017:
Jeremy Gill (author) from Louisiana on November 17, 2017:
You're probably thinking of anime heights, not official video game ones. Primal Groudon is only 5 meters tall.
Arceus's size is 3.2 meters, bruh.
Armadillo on November 16, 2017:
Soooooo no Groudon? pretty sure groudon is larger than at least a Steelix especially in Primal form
Serena on October 31, 2017:
I know the largest pokemon...It is Arceus because he is way bigger than wailord because I know the size os Arceus is it
will swan on October 30, 2017:
alolan exaguttor isn't the largest it's 35'09" , whereas wailord is 47'7"
Bhavyadeep Yadav on October 28, 2017:
Hey Man its rock thanks for showsing this
Jeremy Gill (author) from Louisiana on October 25, 2017:
Anime's a whole different ballgame; it usually scales up the size of "cool" Pokemon like Charizard and Dragonite.
You're referring to a really old season 1 episode featuring Bill and an almost Godzilla-sized Dragonite. Good memory, but like I said, the anime operates under very different rules.
Additionally, old fans may remember the giant Alakazam, Jigglypuff, and Gengar from the Pokeopolis episode of season 1.
Mousam Baishya on October 25, 2017:
One episode it show that one pokemon like dregonite is largest Pokemon
Jeremy Gill (author) from Louisiana on October 20, 2017:
Oh, comments section, you never fail to amuse me.
This was addressed already in a previous comment. My list predated Sun/Moon and Alolan forms.
Weedle is hundreds of 'mons down the line.
@DonALD C TRUmp
I'd say it's ridiculous to vote for a fictional Pokemon for President, but then again, thousands of people voted for Harambe the deceased gorilla in our last election so...
Tyranitar's cool, but he's less than seven feet tall.
Uh, don't send Wailord out over you. Put him on the ground nearby.
Contrary to what the anime would have us believe, I'm taller than a Charizard. You probably are too.
Person on October 20, 2017:
This is actually wrong, Aloloan Exeggutor is the largest.
Cecilia on October 18, 2017:
Where is weedle at
DonALD C TRUmp on October 13, 2017:
kyogre for president 2020
Sam on October 08, 2017:
why isn't tyranitar on the list?
isaac on September 24, 2017:
so how is the bigst
rohan on August 27, 2017:
rayquaza is the best
swag swampert on June 25, 2017:
How can you even USE wailord in a battle!? Once it comes out of a pokeball, WE ALL GET CRUSHED.
newheaton on June 12, 2017:
What about Celesteela?
Flash on June 02, 2017:
Always liked big Pokemon, ever since giant Onix in Red and Blue. Glad him and his evolution made it!
Neev on May 17, 2017:
Where did dragonite go
Cooldad on May 15, 2017:
I find it funny that you call Kyogre a behemoth instead of a leviathan.
wyatt on April 19, 2017:
i thought charazard was one........
Logan rabbitt on April 13, 2017:
Mega Rayquaza is dragon-flying, not pure dragon
Jj on April 08, 2017:
Wow this Pokemon are tall!
ThusTheWorldWasBorn on February 02, 2017:

Jeremy Gill (author) from Louisiana on January 29, 2017:
I'm literally taller than the 5'11'' Mega Salamence.
FeelMahNutz on January 28, 2017:
I thought Mega Salamence was tallest?
yo boi on January 15, 2017:

CactusKing on January 01, 2017:

daquan on December 22, 2016:
lmao here comes celesteela
Jeremy Gill (author) from Louisiana on November 02, 2016:
Thanks for the tip, Cohen. You're right, but this was made before Alolan Pokemon. That's the thing with Pokemon lists, they're constantly changing!
Cohen Rice on November 02, 2016:
Technically this is false. The Biggest Pokémon is Alohan Exegutor being as big as 912 2
Annoying "Actually it's this" guy on October 23, 2016:
Technically P and h POKé are the largest at 80"3
Wailordattack on August 31, 2016:
wailord is my love!!!!!
Simon Poole on August 10, 2016:
What about Dragonite?
Cheese on July 12, 2016:
I really thought that a pokemon like pelkia or from that kind of list would make it to top 10
Jeremy Gill (author) from Louisiana on April 20, 2016:
Cameron, if you're going by anime standards, that's a whole different ballgame. For example, in the show, Charizards tower over humans, each easily standing 7 feet or more, but in the games, they're less than six feet tall.
This list was made using the official Pokedex entries.
Cameron Woods on April 19, 2016:
if you watched hoopa unbound you would see hoopa is bigger than primal kyogre and is probably the biggest pokemon ever and also wheres lugia in this page he is just as big as hoopa and is very powerfull and took hoopa head on in a fight despite hoopa having the advantage plus he is my favourite pokemon ever
Demietrius locherie on January 05, 2016:
cool! my fav is wailord cuz 1.it the biggest and 2. it really friendly and nice! oh yeah and btw nice web :)
