[[File:Masters Legendary Arena Entei.png|200px|thumb|Legendary Arena]]
The '''Legendary Arena''' (Japanese: '''レジェンドバトル''' ''Legend Battle'') is a special battle area in {{g|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 up to 30 [[sync pair]]s. 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 skills 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. {{mas|Medal}}s can also be earned by completing specific missions.

Starting from September 8, 2022, all of the battles are permanently available.

==Legendary Arena: Entei==
{{p|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 could also be battled in the [[Legendary Gauntlet]] from January 20 to February 2, 2022 and July 25 to August 19, 2022.

It is weak to {{type|Water}} moves. Entei sets permanent field effects, such as Physical/Special Damage Reduction, during the fight. It will also raise its critical-hit rate which can't be lowered due to Steady Aim passive skill.

Some of Entei's notable passive skills are:<br>Bar 3:<br>Piercing Gaze: moves never miss.<br>Hostile Environment 10: its {{m|Heat Wave}} and {{m|Sacred Fire}} will always burn the target.<br>On a Roll 9: its {{m|Rock Smash}} and {{m|Iron Tail}} will always lower target's Defence.

==Legendary Arena: Cobalion==
{{p|Cobalion}} was the second Legendary Arena boss Pokémon and could be battled from July 7 to 21, 2020, October 17 to 29, 2020, May 20 to June 3, 2021, September 10 to 24, 2021, and May 10 to 24, 2022. It could also be battled in the [[Legendary Gauntlet]] from January 20 to February 2, 2022.

It is weak to {{type|Fire}} moves. Cobalion is resistant to all damage thanks to Healthy Advantage 8 passive skill.

==Legendary Arena: Tapu Bulu==
{{p|Tapu Bulu}} was the fifth Legendary Arena boss Pokémon and could be battled from November 16 to 30, 2020, August 5 to 19, 2021, February 7 to 21 and June 9 to 23, 2022. It could also be battled in the [[Legendary Gauntlet]] from July 25 to August 19, 2022.

It is weak to {{type|Flying}} moves while on its first and third HP bars, and weak to {{type|Poison}} moves while on its second. It activates the field effect of {{m|Grassy Terrain}} at the beginning of each HP bar and each time it uses its Sync Move; Grassy Terrain increases the power of {{type|Grass}} moves and restores HP when using a Grass-type move. Grassy Terrain can be countered by inflicting {{status|Poison}} or by using "interference" status conditions, such as [[flinch]]ing, {{status|confusion}}, or {{status|bound|trapped}}, although Tapu Bulu will increase its resistance to the latter each time it recovers, until it becomes immune.

{{p|Regirock}} was the sixth Legendary Arena boss Pokémon and could be battled from December 12 to 20, 2020, June 25 to July 9, 2021, November 19 to December 3, 2021, and April 7 to 21, 2022. It could also be battled in the [[Legendary Gauntlet]] from May 24 to June 7, 2022.

It is weak to {{type|Grass}} moves while on its first HP bar, and weak to {{type|Steel}} moves while on its second and third. During the battle, any Pokémon receiving a critical hit will have their Defense lowered; for Regirock, this is the only way to reduce any of its stats. After dropping below 50% on the first and second HP bars, Regirock uses Iron Defense to raise its Defense and block critical hits for a period of time. While on it's second and third HP bar, Regirock will also increase it's resistance to any status interference (flinching, confusion or trapped) each time it recovers from one until it becomes immune.

==Legendary Arena: Cresselia==
{{p|Cresselia}} was the seventh Legendary Arena boss Pokémon and could be battled from February 18 to March 4, 2021, August 20 to September 4, 2021, March 10 to 24, 2022 and July 5 to 19, 2022.

It is weak to {{type|Dark}} moves. While on its first HP bar, Cresselia will boost its stats with {{m|Double Team}} and {{m|Calm Mind}} and use Special Damage Reduction and its Brain Barrier 8 passive skill to reduce special damage; on harder difficulties, it will use its Go Viral 9 passive skill to allow its {{m|Thunder Wave}} to paralyze the player's entire team. On its second HP bar, it will switch to using Physical Damage Reduction and its Brawn Barrier 8 passive skill to reduce physical damage, and it will also add Stat Reduction Defense to its side of the field; on harder difficulties, it will use its Go Viral 9 passive skill to allow its {{m|Toxic}} to badly poison the player's entire team, and on Very Hard, it will gradually heal itself. On its third HP bar, Cresselia will continue its Physical Damage Reduction and Stat Reduction Defense, and it will add Status Move Defense and Status Condition Defense to its side of the field. After the first and second bars are depleted, Cresselia will use the Sure Hit Next and Critical Hit Next effects together with moves that damage the player's whole party.

==Legendary Arena: Latias==
{{p|Latias}} was the eighth Legendary Arena boss Pokémon and could be battled from March 31 to April 14, 2021, November 9 to 23, 2021, and June 27 to July 11, 2022. It could also be battled in the [[Legendary Gauntlet]] from March 24 to April 7, 2022.

It is joined by {{p|Flygon}} and {{p|Alakazam}} which are weak to {{type|Dragon}} and {{type|Dark}} moves respectively. It is weak to Dragon-type moves while on its first HP bar, and weak to {{type|Fairy}} moves while on its second and third. Latias's Fluid Fortification passive skill reduces any damage it takes the more its stats are raised, but lowering its stats causes it to take more damage. While on its second HP bar, Latias will also gain or lose evasiveness if it dodged or failed to dodge, respectively, incoming attacks.

==Legendary Arena: Tornadus==
{{p|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. The missions were available from September 8 to 22, 2022. It could also be battled in the [[Legendary Gauntlet]] from May 24 to June 7, 2022.

It is weak to {{type|Electric}} 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 {{status|Paralysis}}. If paralyzed, Tornadus will use {{m|Toxic}} one time early in the fight; otherwise, it will use {{m|Rain Dance}} instead. It has a chance of curing its paralysis after using a move with Self-Cleanse passive skill. Tornadus resists status changes, such as [[flinch]]ing, {{status|confusion}}, or {{status|bound|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: Moltres==
{{p|Moltres}} was the tenth Legendary Arena boss Pokémon and could be battled from July 12 to 26, 2021 and February 24 to March 10, 2022. It could also be battled in the [[Legendary Gauntlet]] from March 24 to April 7, 2022.

It is weak to {{type|Rock}} moves while on its first and third HP bars, and weak to {{type|Water}} moves while on its second. All [[weather]] conditions remain in effect until replaced with different weather; Moltres has a number of passive skills that activate during [[sunny]] weather, which it summons at the beginning of each HP bar and the halfway point of the second and third bars. Moltres can be [[flinch]]ed, but its resistance to flinching increases each time it recovers until it reaches 9.

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., [[flinch]]ing or {{status|can't escape|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, {{status|confusion}}, or {{status|bound|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.

==Legendary Arena: Terrakion==
{{p|Terrakion}} was the twelfth Legendary arena boss Pokémon and could be battled starting from March 10, 2023.

It is weak to {{type|Psychic}} moves. Terrakion's passive skills increase its damage when its Attack and Sp. Atk are raised, which it can accomplish through moves and passive skills. While on its second and third HP bar, the Clear Advantage passive skill reduces damage while there's no field effect on Terrakion's side of the field, such as [[weather]], [[terrain]], Type Zone, or Type Damage Field.

Some of Terrakion's notable passive skills are:
<br>Bar 2:<br>Clear Advantage 4: Reduces damage taken by 40% when there's no field effect affecting it.						
<br>Bar 3:<br>Clear Advantage 8: Reduces damage taken by 80% when there's no field effect affecting it.

==Event missions==
Because the majority of Legendary Arena rewards are first-time completion rewards and cannot be obtained on reruns, event {{mas|mission}}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 {{mas|Gem}}s by completing these missions. 

The general structure of Legendary Arena event missions is as follows:
{{MastersMissionTable|format=begin}}
{{MastersMissionTable|1|Complete Legendary Arena: <Pokémon>'s Challenge: Part 3<br>with 3 or more sync pairs that share the following theme<br>and with 9 total sync pairs or fewer:<br>• [[File:Theme skill icon region.png|20px|link=]] Region theme skill|Gem|Gems|rew1amt=×300}}
{{MastersMissionTable|2|Complete Legendary Arena: <Pokémon>'s Challenge: Part 3<br>with 3 or more sync pairs that share the following theme<br>and with 9 total sync pairs or fewer:<br>• [[File:Theme skill icon type.png|20px|link=]] Type theme skill|Gem|Gems|rew1amt=×300}}
{{MastersMissionTable|3|Complete Legendary Arena: <Pokémon>'s Challenge: Part 3<br>with 3 or more sync pairs that share the following theme<br>and with 9 total sync pairs or fewer:<br>• [[File:Theme skill icon Trainer group.png|20px|link=]] Trainer group theme skill|Gem|Gems|rew1amt=×300}}
{{MastersMissionTable|format=end|all|Gem|Gems|100}}

Once Legendary Arenas became available permanently, event missions continued to rerun periodically. <!--The following table lists all the times Legendary Arena missions have been available since they were made permanently available:
