Legendary Arena

Legendary Arena

The Legendary Arena (Japanese: レジェンドバトル Legend Battle) is a special battle area in Pokémon Masters EX. Introduced in Version 1.10.5, it features battles against a boss Legendary Pokémon. The player can battle the boss with multiple teams using a set number of sync pairs. Sync pairs that have participated once cannot be used in a team again. The boss has three HP bars and the boss's attack pattern and moves change with each bar. The boss's HP and status conditions are carried over between battles.

The player is able to reset their progress at any point. This will reset the current challenge status, and hence reset the opponent's HP and status conditions, as well as any sync pairs used. The player's progress is also automatically reset after a week has elapsed since the last attempt.

Arena rewards are given every time the player depletes one the boss's HP bars to 0. Medals can also be earned by completing specific missions.

Legendary Arena: Entei

Entei was the first Legendary Arena boss Pokémon and could be battled from June 11 to 25, 2020, October 5 to 17, 2020, January 14 to February 1, 2021, June 9 to 23, 2021, and October 4 to 18, 2021. It is weak to Water-type moves. On the very hard difficulty and while on the third HP bar, Entei has the Piercing Gaze passive skill allowing its moves to always hit. It also has Hostile Environement 10 passive skill which makes sure that either its Heat Wave or Sacred Fire always burn the target.

Legendary Arena: Tornadus

Tornadus was the ninth Legendary Arena boss Pokémon and could be battled from April 22 to May 6, 2021, September 21 to October 5, 2021 and December 9 to 23, 2021. It is weak to Electric-type moves. Normally, Tornadus is resistant to physical damage while on its first HP bar, to special damage while on its second, and all damage while on its third, and it is also protected from critical hits while on the third HP bar. These protections can be negated by inflicting Tornadus with a status condition, although it is immune to all except Paralysis. If paralyzed, Tornadus will use Toxic one time early in the fight; otherwise, it will use Rain Dance instead. It has a chance of curing its paralysis after using a move with Self-Cleanse passive skill. Tornadus resists "interference" status conditions, such as flinching, confusion, or trapped, with its resistance increasing each time it recovers from one, until it becomes immune. On the very hard difficulty and while on the third HP bar, Tornadus will have the Piercing Gaze passive skill which allows its moves to always hit.

Legendary Arena: Uxie

Uxie was the eleventh Legendary Arena boss Pokémon and could be battled from October 22 to November 5, 2021. It is weak to Ghost-type moves. While on its first HP bar, the Healthy Advantage passive skill reduces damage while Uxie is unaffected by status conditions; on the second bar, the Acute Senses passive skill reduces damage unless Uxie is affected by status changes (e.g., flinching or restrained); and both passive skills take affect when Uxie is on its third HP bar. Additionally, passive skills increase Uxie's resistance to a status condition or interference condition (flinching, confusion, or trapped) each time it recovers from one, until it becomes immune. On Very Hard difficulty, Uxie will also apply Special Damage Reduction to its side of the field while on its first bar and Physical Damage Reduction while on its third bar.
