Ultimate Battle

An Ultimate Battle (Japanese: 究極高難度バトル) is a special type of permanent battle content in Pokémon Masters EX. Introduced on November 14, 2023, these battles have the Ultimate difficulty level and pit the player against a powerful sync pair generally formed with a Legendary Pokémon. Ultimate Battles are standard team battles, so players can use up to three sync pairs at once to battle the boss sync pair and their allies. Some boss sync pairs endure the first attack that would put them below a certain percentage of their maximum HP with that percentage of their maximum HP, similar to the HP bars used by Legendary Arena bosses.

Ultimate Battles are accessed from the Challenge the Strong menu in the Side Area section. This menu is unlocked after the player completes the Champion Stadium on Hard Lv. 1 difficulty for any region.

Each Ultimate Battle awards the player with 300 Gems the first time it is completed. There are no rewards for completing the battle subsequent times.

Anabel's Flickering Flames

Anabel was the first Ultimate Battle boss, forming a sync pair with Entei. This battle was first made available on November 14, 2023. Anabel & Entei and their allies are weak to Water-type moves.

Anabel & Entei set harsh sunlight upon entering battle and each time they use their sync move. They and their allies have several passive skills that give them benefits in sunny weather, such as powering up their attacks and reducing the damage they take. Anabel & Entei take less damage from attacks the more their stats have been raised in total, and field effects they set are permanent unless replaced. In addition, Anabel & Entei endure the first attack that would put them below 60% of their maximum HP with 60% of their maximum HP. So, the recommended strategy is to change the weather and lower Anabel & Entei's stats. Also, attacks from Anabel & Entei are powered up if their target is burned.

Thorton's Freezing Frost

Thorton was the second Ultimate Battle boss, forming a sync pair with Articuno. This battle was first made available on December 8, 2023. Thorton & Articuno and their allies are weak to Fire-type moves.

Thorton & Articuno endure the first attack that would put them below 60% of their maximum HP with 60% of their maximum HP. Thorton & Articuno and their allies have their Defense and Special Defense tripled when they are not affected by a negative status change. Thorton & Articuno have their Defense tripled upon entry, but this switches to Special Defense when they reach 60% of their maximum HP. Meanwhile, their allies have their Defense tripled the whole time. In addition, Thorton & Articuno and their allies' attacks are powered up when their Defense is raised. So, the recommended strategy is to inflict negative status changes, lower the opponents' Defense, and use both physical and special attacks.

Darach's Daring Wings

Darach was the third Ultimate Battle boss, forming a sync pair with Staraptor. This battle was first made available on January 9, 2024. Darach & Staraptor and their allies are weak to Rock-type moves.

Darach & Staraptor endure the first attack that would put them below 40% of their maximum HP with 40% of their maximum HP. They and their allies have several passive skills that give them benefits when they are unaffected by any field effects, such as powering up their attacks and tripling their Defense and Special Defense. In addition, the opponents have relatively lower resistance to Damage Fields, but when Darach & Staraptor's HP reaches 40% or lower, they won't receive any damage from them. So, the recommended strategy is to set up field effects such as Damage Fields and weather conditions.

Argenta's Glistening Crystals

Argenta was the fourth Ultimate Battle boss, forming a sync pair with Suicune. This battle was first made available on February 16, 2024. Argenta & Suicune and their allies are weak to Grass-type moves.

Argenta & Suicune endure the first attack that would put them below 50% of their maximum HP with 50% of their maximum HP, and will remove any negative status changes inflicted on them and their allies. Argenta & Suicune make the weather rainy upon entering battle and the first time their HP reaches below 50% of their maximum HP. Also, the Lass & Slowbro set up a Psychic Terrain upon entering battle or by using Psychic Terrain. Argenta & Suicune and their allies have several passive skills that give them benefits in rainy weather, such as powering up their attacks, reducing the damage they take and protecting them from status conditions and certain negative status changes. They also have their moves powered up when Psychic Terrain is in effect. Field effects they set are permanent unless replaced. In addition, Argenta & Suicune and their allies have their Defense and Special Defense tripled when they are unaffected by negative status changes. So, the recommended strategy is to change the weather and terrain, and inflict negative status changes.

Palmer's Rumbling Might

Palmer was the fifth Ultimate Battle boss, forming a sync pair with Regigigas. This battle was first made available on March 9, 2024. Palmer - Regigigas and their allies are weak to Fighting-type moves.

Due to the combination of their passive skills, attacks from Palmer & Regigigas and their allies always land a critical hit, even if the player's team has passive skills like Vigilance. Field effects they set are permanent unless replaced. In addition, upon using their first sync move, Palmer & Regigigas set up a Normal Zone, immediately followed by a Max Strike that hits all opponents due to the passive skill Targets Maxed. After Palmer & Regigigas use their sync move, their sync buff is raised by an additional three ranks, making it practically impossible to survive Max Strike. So, the recommended strategy is to defeat Palmer & Regigigas before they use their sync move.

Lucy's Entangling Venom

Lucy was the sixth Ultimate Battle boss, forming a sync pair with Seviper. This battle was first made available on April 9, 2024. Lucy & Seviper and their allies are weak to Ground-type moves.

Lucy & Seviper endure the first attack that would put them below 80% and 40% of their maximum HP with 80% and 40% of their maximum HP respectively, and will remove any status conditions and negative status changes inflicted on them. Lucy & Seviper and their allies have their attacks powered up when their Speed is raised. In addition, their moves with a chance of poisoning the target are guaranteed to do so thanks to their passive skill, with their attacks being powered up against poisoned opponents. So, the recommended strategy is to lower the opponents' Speed and prevent the player's team from being poisoned.

Leon's Unbeatable Blaze

Leon & Charizard and their allies have their Defense and Special Defense tripled when they are not affected by a field effect, and their moves are also powered up. In addition, when they are not affected by a status condition, their moves, sync moves, and max moves are powered up, and they are immune to critical hits. Leon & Charizard endure the first attack that would put them below 60% of their maximum HP with 60% of their maximum HP, at which point they also remove any status conditions inflicted on them and their allies as well as removing any weather, terrain, or zone on the field of play. Any move used by Leon & Charizard's allies will put every Pokémon it hits to sleep, unless they are immune to sleep, and their moves are powered up against opponents that are affected by a status condition. So, the recommended strategy is to set Electric Terrain and inflict status conditions on the opponents.

Nita & Landorus endure the first attacks that would put them below 80% and 50% of their maximum HP. Nita & Landorus cause the sandstorm upon entering battle and the first time their HP reaches below 80% and 50% of their maximum HP. Nita & Landorus and their allies have several passive skills that give them benefits in sandstorm, such as powering up their attacks, restoring their HP. The duration of a sandstorm is extended due to Nita & Landorus's passive, Sand Alert 5. Nita & Landorus and their allies have their Defense and Special Defense tripled when their Speed is raised. So, the recommended strategy is to change the weather and lower the opponents' Speed.

Noland & Machamp endure the first attack that would put them below 80% and 50% of their maximum HP with 80% and 50% of their maximum HP respectively. They and their allies know Fissure and Earthquake, and they have the skills Piercing Gaze and Piercing Blows, which make their moves never miss, ignore damage-reducing passive skills, and ignore the Enduring effect. They also have several skills that raise their stats, apply the Critical Hit ↑ Next effect, and maximize their Physical Moves ↑ Next effect. In addition, each time Noland & Machamp use their sync move, their total sync move countdown is reduced by one. So, the recommended strategy is to avoid the opponents' moves and knock them out as quickly as possible.

When they and their allies are not affected by a field effect, their Defense and Sp. Def are tripled, and their moves and sync moves are powered up. Their moves and sync moves are also powered up the more their stats are raised, and their allies can raise the whole team's stats each time they use a move. Their allies can also lower the accuracy of the whole team. While not immune to status or interference conditions such as sleep and flinching, they gain an extended Condition Nullification effect each time they recover from a status or interference condition. So, the recommended strategy is to set up a Dark Damage Field and lower the opponents' stats or prevent them from increasing their stats.

Evelyn & Latios and their allies take less damage from attacks the more their stats have been raised in total. Evelyn & Latios's moves and sync moves are powered up the more their Sp. Atk has been raised, while their left and right allies' moves are powered up the more their Sp. Def and Attack, respectively, have been raised. Evelyn & Latios endure the first attack that would put them below 60% of their maximum HP with 60% of their maximum HP, at which point they also boost their five main stats by two ranks each. In addition, they boost their five main stats by one rank each after each time they use their sync move. So, the recommended strategy is to lower the opponents' stats, especially Attack, Sp. Atk, and Sp. Def.
