After nearly 30 years of development, the Pokémon anime has introduced hundreds of creatures with powers far beyond the original limits. While early seasons focused on type advantages and strategy, the arrival of Legendary and Mythical Pokémon raised the stakes to a whole new level.
Here are the 10 strongest Pokémon in the anime, recognized for their feats and demonstrated power.
10. Ash-Greninja
Ash-Greninja is a unique case, appearing thanks to the Bond Phenomenon between Ash and Greninja. Their perfect synchronization allows them to share emotions and senses, elevating their fighting ability to an unprecedented level.
In the Kalos League, Ash-Greninja easily defeated Sawyer’s Mega Sceptile and held a fierce battle against Alain’s Mega Charizard X. Its speed, reflexes, and the powerful Giant Water Shuriken make Ash-Greninja one of the strongest Pokémon ever seen without Mega Evolution.
9. Cynthia’s Garchomp
The ace of Champion Cynthia, Garchomp is known for its balanced offense and defense. This Dragon-type Pokémon boasts incredible speed and remarkable durability, able to withstand many super-effective attacks and keep fighting.
Moves like Dragon Rush and Dragon Pulse allow Garchomp to dominate most Champion-level opponents, making it one of the most reliable Dragon-types in the anime.
8. Ultra Necrozma
Ultra Necrozma is Necrozma’s strongest form after absorbing all the light from Solgaleo or Lunala. Its Photon Geyser attack releases immense energy, bright enough to illuminate the world and open Ultra Wormholes connecting different dimensions.
When fully charged with light energy, Ultra Necrozma nearly overwhelms all opponents with power far beyond ordinary Pokémon.
7. Mewtwo
From its very first appearance, Mewtwo set a new standard for Psychic-type power. Created from Mew’s DNA, it possesses overwhelming psychic abilities, capable of manipulating massive objects, erasing memories, generating energy shields, and even cloning entire Pokémon teams.
Its absolute control over power makes Mewtwo one of the most dangerous Pokémon in anime history.
6. Giratina
More than just a Legendary Pokémon, Giratina rules the Distortion World, where physical laws are completely reversed. It can freely open spatial rifts to travel between dimensions and pull opponents into its domain.
Giratina’s power scale goes beyond typical battles, as it plays a key role in maintaining balance between worlds.
5. Leon’s Charizard
As the ace of World Champion Leon, Charizard is considered the strongest Fire-type Pokémon in the anime. Its terrifying strength lies in its versatile moveset. Leon constantly adapts Charizard’s techniques to counter opponents, making it nearly flawless.
Gigantamax Wildfire and Dragon Pulse have helped Charizard defeat numerous powerful foes, including Alain’s Mega Charizard X.
4. Ash’s Pikachu
Although it never evolved into Raichu, Pikachu boasts a record that many Pokémon envy. Throughout its journey, Pikachu has defeated numerous Legendary Pokémon, toppled Champion-level aces, matched Gigantamax Charizard, and mastered the Z-Move 10,000,000 Volt Thunderbolt.
Thanks to decades of battles alongside Ash, Pikachu is regarded as one of the strongest Pokémon ever featured in the anime.
3. Mega Rayquaza
Mega Rayquaza breaks all the rules of Mega Evolution. Without a Trainer, Key Stone, or Mega Stone, it can Mega Evolve on its own using special energy from a meteor.
Its overwhelming power was enough to stop the battle between Primal Groudon and Primal Kyogre, saving the Hoenn region from disaster.
2. Eternatus
Eternatus caused the Darkest Day event in the Galar region. The Galar Particles it released forced many Pokémon into uncontrollable Dynamax or Gigantamax states.
Even Leon and Charizard couldn’t defeat Eternamax Eternatus. It took the combined efforts of Zacian, Zamazenta, Ash, and Goh to seal this creature away.
1. Arceus
Topping the list is none other than Arceus, the Pokémon considered the creator of the entire Pokémon world. Arceus created the Creation Trio, Dialga, Palkia, and Giratina, shaping time, space, and antimatter.
Thanks to its Life Plates, Arceus can change its type at will, always gaining the upper hand against any opponent. In the movie Arceus and the Jewel of Life, Arceus’s wrath alone is powerful enough to destroy entire civilizations.
Compared to Mewtwo, Ultra Necrozma, or any other Pokémon, Arceus stands in a league of its own.
