Top 10 Heaviest Pokémon of All Time

In between "Pokémon" journeys, Jeremy enjoys working as a pharmaceutical chemist and campus manager.

Throughout the years, we've been treated to several shapes and sizes of Pokémon, some much larger than others. But height doesn't always equal weight, with tall creatures like Alolan Exeggutor weighing barely half of today's lightest unit.

While most of the bulkiest monsters match their mass with size, you might be surprised at the minuscule stature some of today's entries bear. So, with hundreds of different creatures running rampant, which units weigh the most? These are the ten heaviest Pokémon of all time!

What Are the Heaviest Pokémon in the World?

10. Giranta (Altered Forme)

9. Melmetal

8. Stakataka

7. Guzzlord

6. Mudsdale

5. Mega Metagross

4. Eternatus

3. Groudon/Primal Groudon

2. Cosmoem

1. Celesteela

Giratina (Altered Forme)

Giratina (Altered Forme)

10. Giratina (Altered Forme)

Weight: 750.0 kg (1653.5 lbs)

Type: Ghost/Dragon

Ironically, Giratina's so-called "Altered Forme" is the mode initially introduced in Diamond and Pearl; its separate Origin Forme debuted in Pokémon Platinum. Stat-wise, Altered is more defensive while Origin is more offense-oriented, but they share the same base stat total of 680. Strangely, despite Origin being taller, Altered is actually Giratina's bulkier mode, weighing about the same as ten adult humans!

Melmetal

Melmetal

9. Melmetal

Weight: 800.0 kg (1763.7 lbs)

Type: Steel

Debuting in Pokémon: Let's Go Pikachu and Pokémon: Let's Go Eevee offers a fierce legendary with fantastic HP, Attack, and Defense, although he's terribly slow. Still, he's packing a strong defensive type and signature Double Iron Bash attack, which hits twice and can flinch.

Stakataka

Stakataka

8. Stakataka

Weight: 820.0 kg (1807.8 lbs)

Type: Rock/Steel

Introduced in Generation 7's Ultra Sun and Ultra Moon, Ultra Beast Stakataka's stat spread resembles Mega Steelix's (who just missed this list), heavily favoring Defense while bearing an atrocious speed. Stakataka wields several resistances and an immunity to Poison, but beware, as two of his three weaknesses (Fighting and Ground) will hit him for quadruple damage!

Guzzlord

Guzzlord

7. Guzzlord

Weight: 888.0 kg (1957.7 lbs)

Type: Dark/Dragon

Another Ultra Beast from Generation 7, Guzzlord carries a surprisingly low stat total for a legendary, bearing decent Attack but low Defenses and Speed. However, he somewhat compensates with a daunting HP value, and he puts his colossal weight to good use with the Steel technique "Heavy Slam", dealing more damage against foes who weigh less than him—which is basically everybody.

Mudsdale

Mudsdale

6. Mudsdale

Weight: 920.0 kg (2028.3 lbs)

Type: Ground

The upgraded form of Mudbray, Mudsdale is a pure-Ground breed from the Alola region. Despite his impressive stature, he's not legendary, but his 920 kilograms sure do pack a punch, especially with a base Attack of 125. Sorry, Yoda, sometimes size does matter.

Mega Metagross

Mega Metagross

5. Mega Metagross

Weight: 942.9 kg (2078.7 lbs)

Type: Steel/Psychic

This Hoenn classic already weighed a ton in his base form, but nearly doubles his weight upon mega evolving. As a pseudo-legendary, Metagross's stats rank at an impressive 600, but his mega form carries a daunting 700, favoring the physical attributes while still being well-rounded elsewhere, letting him fight competently on any front.

Eternatus

Eternatus

4. Eternatus

Weight: 950.0 kg (2094.4 lbs)

Type: Poison/Dragon

The ultimate legendary in the Galar region, Eternatus has a unique typing and dominating size. His weight becomes ??? in his monstrous Eternamax Eternatus form, but we're not counting the special shenanigans of the Dynamaxing-esque Galarians.

Still, his Eternamax form is easily the strongest Pokémon of all time, bearing a ridiculous stat total of 1125.

3. Groudon/Primal Groudon

Weight (Regular): 950.0 kg (2094.4 lbs)

Type (Regular): Ground

Weight (Primal): 999.7 kg (2204.0 lbs)

Type (Primal): Ground/Fire

Pokemon Ruby's mascot Groudon lumbers in with a fierce 950 kilos, and when you unlock his Primal form (similar to a mega evolution) in Omega Ruby, he further enlarges to a whopping 999.7, missing today's top spot by less than half a pound. In addition to their sizes and stats, Groudon and Primal Groudon wield the "Drought" and "Desolate Land" weather traits, some of the best abilities in the games.

Cosmoem

Cosmoem

2. Cosmoem

Weight: 999.9 kg (2204.4 lbs)

Type: Psychic

This unorthodox creature not only bears two evolutionary paths (morphing into Solgaleo in the Sun games and Lunala in the Moon), but actually loses weight when it evolves. Cosmoem ties for heaviest creature, weighing a massive 1000 kilograms, but it's actually one of the smallest Pokémon, being only a tenth of a meter tall. Big things come in little packages, eh?

Celesteela

Celesteela

1. Celesteela

Weight: 999.9 kg (2204.4 lbs)

Type: Steel/Flying

Johto's Skarmory long remained the only Steel/Flying blend—until this Alolan Ultra Beast entered the fray. Celesteela's 570 stats are a bit low for a legendary, but her excellent type pairing provides eight resistances and two immunities with just two weaknesses (Fire and Electric); fortunately, neither hit her for quadruple damage.

Thus, Celesteela's fantastically durable, shrugging off strikes from several elements. While she weighs the same as Cosmoem, her 30-foot tall stature lends her a presence her cosmic counterpart lacks, making her one of the largest and the heaviest Pokemon of all time!

Does a Pokémon's Weight Matter?

Pokémon battles are influenced by many factors, from your monster's stats to its type, ability, held item, and more. Admittedly, weights largely (if you'll pardon the pun) serve as extra information to those browsing the Pokedex. That said, they do occasionally come into play. Attacks like "Low Kick" and "Grass Knot" deal more damage against bulky foes, and the Fancy and Light Cup tournaments restrict competitors based on weight. Additionally, the Heavy Ball Pokéball variant excels at capturing sizable monsters, so don't dismiss mass as completely irrelevant in combat.

But for now, as we eagerly await Nintendo's next batch of gargantuan creatures, vote for your favorite behemoth and I'll see you at our next Pokémon countdown!

Well...... It's news to me, I never knew Cosmoem weighed that much

Sword Fan on December 29, 2019:

Eternatus is same weight as base groundon while being 65'7" in height geez!

Invalld on September 28, 2019:

I am pretty sure Cosmoem is heavy and small at the same time because it represents a singularity, except a bigger and less heavier. Then when it "blows up" it makes something a lot bigger. Just as the singularity that started the universe did, a very very very small dot, all the things in the world in it, and then it blew up and made the world we are in today. So yes, I believe Cosmoem is a singularity but in less extent.

Why does Cosmoem weigh so much?

@Poppy

Glad you enjoyed some of the underrated Mystery Dungeon titles! And don't tempt me with April Fool's ideas : )

Aww, I remember Groudon from Pokémon Myster Dungeon Red Rescue Team. Unfortunately I haven’t played any Pokémon games since Pokémon Y, but I might get into them again. Good list of heavy Pokémon, and props to you for not ending it with “1. Your mom.”
