Legendary Arena

The Legendary Arena (Japanese: レジェンドバトル Legend Battle) is a special battle area in . Introduced in Version 1.10.5, it features battles against a boss Legendary Pokémon. The player can battle the boss with multiple teams using up to 30 sync pairs. Sync pairs that have participated once cannot be used in a team again. The boss has three HP bars and its attack pattern, moves, and passive s 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 when the player depletes one of the boss's HP bars to 0; repeatable General rewards consist of one 1★ Level-Up Manual per HP bar. s can also be earned by completing specific missions.
Starting from September 8, 2022, all of the battles are permanently available.

==Legendary Arena: Terrakion==

==Event missions==
Because the majority of Legendary Arena rewards are first-time completion rewards and cannot be obtained on reruns, event s were included during the reruns of Legendary Arenas to encourage players to take on the challenge again with certain team restrictions. These missions required players to complete the most difficult version of the Legendary Arena with nine sync pairs or fewer, and at least three sync pairs of those nine had to have a certain theme skill. Players could earn up to 1,000 s by completing these missions. Once Legendary Arenas became available permanently, event missions continued to rerun periodically.
Legendary Arena: Raikou was the only Legendary Arena to include event missions at the same time as its debut.
The general structure of Legendary Arena event missions is as follows:
The only Legendary Arena event missions that did not follow this format exactly were Latias's missions in June and October 2022, which only asked players to use 2 or more sync pairs of the designated region theme skill.
The following table lists all the times Legendary Arena missions have been available, and what theme skills were required:
