Eternamax

Eternamax (Japanese: ムゲンダイマックス Infinite Daimax) is a kind of form change unique to Eternatus that was introduced in Generation VIII. In the core series, it is unobtainable and has only appeared in Pokémon Sword and Shield, but it also appears in other media and spin-off games such as Pokémon Masters EX and Pokémon GO.

Eternatus only transforms into Eternamax during the climax of Sword and Shield, where it absorbs a massive amount of energy to undergo the transformation.

In the core series games

Unlike Dynamax or Gigantamax, the transformation is unobtainable to the player, but appears when Eternabeam is used. The only known Pokémon to have this transformation is Eternatus. This transformation occurs when a Pokémon absorbs massive amounts of energy at once. When in this form, Eternatus is releases an infinite amount of energy from its core, resulting in a distortion of space-time. This energy, known as Galar particles, is what results in the Dynamax phenomenon in wild Pokémon. In turn, while Eternatus is absorbing energy, Trainer-owned Pokémon are unable to Dynamax themselves.

History

During the climax of Pokémon Sword and Shield, Chairman Rose awakens the sleeping Eternatus underneath Hammerlocke Stadium, resulting in destruction of the laboratory beneath it, as Eternatus was overloaded with energy. Continuing to absorb the energy from around Galar, the region's Champion, Leon attempts to stop Eternatus. To no avail, as the Pokémon prevents his team from being able to Dynamax. The player and Hop manage to defeat Eternatus, before it began to Eternamax from the amount of energy it had taken in. Eternamax Eternatus proceeds to absorb more energy while preventing the player's and Hop's Pokémon from attacking. The player and Hop then summon Zacian and Zamazenta, negating this power. A special Max Raid Battle ensues, resulting in the player catching Eternatus, ending its Eternamax transformation.

Effect

While Eternamax cannot be obtained by the player, while facing off against it, Eternamax Eternatus functions similar to a Dynamax Pokémon in a Max Raid Battle. It can negate the effect of the player's Pokémon's Abilities and stat changes, cure itself of non-volatile status conditions, and use Max Moves in battle. After defeating it, the player will always catch it.

However, it cannot create a protective barrier like Rank 3 and above Max Raid Battle opponents can. Additionally, it does not take increased damage from Behemoth Blade, Behemoth Bash, or Dynamax Cannon.

In the spin-off games

Pokémon GO

Eternamax Eternatus appeared in Max Battles globally from August 23-24, 2025. However, like in the core series games, Eternamax cannot be obtained by the player. Instead, defeating Eternamax Eternatus in Max Battles rewards large quantities of Eternatus Candy and Eternatus Candy XL.

When attempting to capture Eternatus, via rewards from either Timed Research or the GO Pass: Max Finale, Eternatus will be Eternamaxed. When Eternatus is caught, its Eternamax transformation ends.

Pokémon Masters EX

Leon, while wearing his sygna suit, is the only Trainer to use Eternamax in Pokémon Masters EX, where it is treated as a variation of Dynamax. Dynamax Cannon is replaced by Eternabeam when Eternatus Eternamaxes, treating the latter move as Eternatus's max move, even though it isn't one in the core series games.

When the two of them attacked Eternatus together, all three Pokémon vanished in a bright flash of light.

Trivia

• Unlike Gigantamax forms, Eternamax Eternatus has its exact size listed in the Pokédex without being followed by a plus, though its weight is listed as ????.? lbs, just like all Gigantamax forms.
• A Shiny Eternamax Eternatus cannot be registered legitimately in the Pokédex in Pokémon Sword and Shield, as the only way to see one is in the animation for a Shiny Eternatus using Eternabeam, which is not considered a true form change. However, it can be registered in Pokémon HOME by registering a Shiny Eternatus, as both forms will be automatically registered upon depositing an Eternatus into HOME.
