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 gauges and the boss's attack pattern and moves change with each gauge. 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 gauges to 0. Medals can also be earned by completing specific missions.

Entei was the first Legendary Arena boss Pokémon and could be battled from June 11 to 25, 2020 and October 5 to 17, 2020. Entei had a weakness to Water-type moves.

Legendary Arena: Tapu Bulu

Tapu Bulu was the fifth Legendary Arena boss Pokémon and could be battled from November 16 to 30, 2020. Tapu Bulu would switch from a weakness to Flying-type moves to a weakness to Poison-type and then back after each HP bar was depleted. It would activate the field effect of Grassy Terrain at the beginning of each HP bar and each time it used its Sync Move; Grassy Terrain increases the power of Grass-type moves and restores HP when using a Grass-type move. Players were encouraged to counter by inflicting Poison or by using "interference" status conditions, such as flinching, confusion, or trapped, although Tapu Bulu would increase its resistance to the latter each time it recovered.
