The '''Battle Hall''' (Japanese: '''バトルステージ''' ''Battle Stage'') is a [[Battle facility|facility]] located in the northwestern corner of the {{gdis|Battle Frontier|IV}} in [[Generation IV]]. The stadium is a huge {{wp|catwalk}}, in where people walk down the catwalk to the battleground, while fans take a number of photos and the spotlights shine all over the place. There is also a red carpet on the floor, all the way from the entrance to the stadium. 

==Challenges==
The Battle Hall is unique from any other facility in the {{gdis|Battle Frontier|IV}}, as there are 10 battles per round instead of the usual 7, and only one Pokémon can be used in a single battle, meaning the battles are one-on-one. Before entering the Battle Hall, the player will be asked to select one Pokémon level 30 or higher for entry. If it is a different Pokémon from last time, the attendant will warn the player that they are using a different Pokémon, as Pokémon are used in winning streaks, and if the player uses a different Pokémon, the streak will be lost. If doing a Double Battle challenge, the player must enter two of the same species of Pokémon. 

Once the Pokémon is entered, the player will go down the runway and will have to choose from a list of types which [[type]] they want to battle. As the player uses only a single Pokémon against a variety of different opponents, their primary advantage comes from many of those opponents being significantly lower level than the player. If the Pokémon has a particularly disadvantageous type, there is a choice to be made about whether to get that type out of the way early, when the level difference is greatest and the player may be able to use it to overcome the type disadvantage, or to play other types to build up a streak without worrying as much about Pokémon of that type. As the only thing known about an opponent is one of the types of their Pokémon, sometimes that Pokémon's second type may counteract an advantage the player was expecting to have; for example, a {{type|Fighting}} Pokémon selecting a {{type|Dark}} opponent, only to find that the {{2t|Ghost|Dark}}-type {{p|Spiritomb}} is immune to Fighting moves.

As the player wins against each type, that type raises in rank, causing further challenges against that type to increase in level. The player gets their Pokémon fully healed, has the option to suspend or retire the current streak as well as save the most recent battle to the [[Vs. Recorder]], then returns to the grid selection and can challenge the same type again (unless Rank 10 of that type was just beaten) or a different type, until the round of 10 battles has been completed. Each type begins at Rank 1, and increases to a maximum of Rank 10, after which no further challenges are allowed against that type.

When two players team up for a multi battle, all types start from rank 10, and the players cannot choose the same type more than once. This means that they have to battle exactly 10 of the 17 types in each round.

Opposing Pokémon's levels are determined by the formula
<math display="block">L = \min\left(Level_{player}, \left\lceil Level_{base} + {types \over 2} + (rank - 1) \cdot increment \right\rceil \right)</math>
where
* <math>Level_{player}</math> the level of the player's Pokémon
* <math>Level_{base}</math> is the base level for opponents to start at, which is <math>Level_{player} - (3 \cdot \sqrt{Level_{player}})</math>
* <math>types</math> is the number of types, excluding the currently selected type, which have progressed to Rank 2 or higher
* <math>rank</math> is the rank of the currently selected type
* <math>increment</math> is the level increase per rank, which is <math>{\sqrt{Level_{player}} \over 5}</math>

The effect of the player's level on the opponents' base level (<math>Level_{base}</math>) and increase per rank (<math>increment</math>) can be seen in the following chart.

Trainers at the Battle Hall use Pokémon from a different roster than that of the other facilities in the {{gdis|Battle Frontier|IV}}. Pokémon with [[List of Pokémon by base stats (Generation II-V)|base stat totals]] below 340 (Group 1) can appear in Rank 1-5, Pokémon with BST between 340 and 439 (Group 2) appear in Rank 3-8, Pokémon with BST between 440 and 499 (Group 3) appear in Rank 6-10, and Pokémon with BST 500 or higher (Group 4) are restricted to Rank 9-10. The same species of Pokémon cannot appear multiple times as an opponent within the same round of 10 battles unless all the possible Pokémon that can appear in a given type and rank have already been seen earlier in the round, but different stages of a single evolutionary line are allowed to appear in the same round.

===Gaining fans===
In the Battle Hall, the player will gain fans as their total record or their winning streak increases. If the player is a female, their major fan is Winston, and if the player is a male, their major fan is Serena. They can be found in the Battle Hall lobby in various locations with varying dialogue. The player will also get visitors cheering them on in the lobby. If the player's total record is over 500 in {{game|Platinum}}, they will get the professor's assistant. If the record is over 1,000, the player will get [[Johanna]], and over 10,000 will get [[Professor Oak]] or [[Jasmine]]. In {{game|HeartGold and SoulSilver|s}}, if the record is over 1,000, the player will get the {{jo|Mom|player character's mother}}, {{ga|Ethan}}, or {{ga|Lyra}}, and over 10,000 will get Professor Oak or [[Whitney]].

====Extra Battle Points====
At the Battle Hall, the staff member next to the monitor will keep track of the player's total record, which is how many successive wins the player has earned with all of their Pokémon. For example, if two different Pokémon have both won 10 times, then the total record is 20. The player earns [[Battle Point|BP]] at the end of each round of 10 battles based on how far they are into the current streak, and if that streak pushes the total record across certain milestones, bonus BP will be awarded for that as well.

===Hall Matron===
[[Argenta]] is the [[Frontier Brain]] for the Battle Hall. She can be challenged on the 50th battle of a streak, unlike all other Frontier Brains whose first challenge comes on the 21st battle. Argenta uses a Pokémon chosen from the same [[List of Pokémon by base stats (Generation II-V)|base stat total]] grouping that the player's Pokémon belongs to (339 or lower, 340-439, 440-499, 500 or higher), but otherwise chosen at random without regard for the player's selected type. Argenta's Pokémon will always match the level of the player's Pokémon, even for levels in which no other opponent's level is capable of getting that high. Once defeated, she will give away the silver commemorative print. Argenta can be challenged again after 170 consecutive battles, with the same rules; on her second challenge she will only use a [[Battle Hall/Pokémon (Group 4)|Pokémon with a base stat total of 500 or greater]], and will give away the gold commemorative print when defeated. 

After the player defeats Argenta for the second time and extends a streak to 170 wins, the player is allowed to continue the streak with further rounds. The grid at that point resets to be equivalent to having Rank 9 cleared in every type, and the player must then choose ten different types to challenge at rank 10 during the following round. Once all types have been defeated again, the grid resets again to the same point, until the streak ends.

===Pokémon Adventures===
In [[Pokémon Adventures]], the challenger is allowed to choose the type of [[Argenta]]'s Pokémon, unlike in the {{pkmn|games}}.

===={{MangaArc|Platinum}}====
The Battle Hall first appeared in ''[[PS418|Deprogramming Porygon-Z]]'' as a part of the {{gdis|Battle Frontier|IV}}. In ''[[PS429|Dealing with Dragonite]]'', {{adv|Platinum}} was shown to have reached Argenta after 169 battles and two days without sleep. For her challenge, Platinum had chosen to use her {{TP|Platinum|Froslass}}, and in the final battle, she came face to face with Argenta's {{pkmn2|rental}} {{p|Dragonite}}. During the battle, Platinum mused to herself how, despite knowing everything about her Froslass, whom she had [[PS388|once faced as her opponent]] when she had been under [[Candice]]'s ownership, only now, after going through 169 consecutive battles with her, she had come to truly understand her.

Despite Froslass having a major type advantage over Dragonite, she still took heavy damage from the [[Pokémon category|Dragon Pokémon]]'s {{m|Steel Wing}}. However, thanks to the [[Babiri Berry]] that Platinum had given Froslass to [[held item|hold]] before the battle, the Snow Land Pokémon was able to survive the super effective hit and defeat Dragonite with {{m|Ice Shard}}, earning Platinum her fourth [[commemorative print]].
