Mix 'n Match

Mix ‘n Match is a battle mode in the Nightclub that lets the player battle against two other characters in a Double Battle format.
==General Info==
The player can select a partner and two opponents from the list of available characters and their teams from the list of their Theme Team, as well as the Field of the battle. The player can also choose not to bring a partner for a double battle, which will double the amount of BP reward. All of the player's Pokemon will be set to level 100.
===Opponent Requirements===
For a character to be available as opponents, they only need to be physically present in the nightclub. Characters might not appear in the club because not all of them are in the club at the beginning of Postgame, or the Postgame quests involving them are being active.
===Partner Requirements===
For a character to be available as partners, there are several requirements. The first requirement is that they need to be physically present in the nightclub, same as above. For most characters, the second requirement only involves Relationship Points: if the player's points with a character is equal or larger a certain number, that character is available.
For most characters, whether their Relationship Point requirements are met or not is determined at the very start of Postgame. That means if the player's points with a character doesn't meet that character's requirement at the start of Postgame, that character is permanently unavailable as a partner. 
===Special Requirements===
* For Florinia to be a partner, there is a Relationship Point requirement of 0, and a third requirement named "Rini Has Feelings!". This requirement is satisfied if the player defeats Solaris on Pyrous Mountain and on the Reshiram Route, or after the player completes the Latias & Latios Quest. That means if the player has 0 points with Florinia at the beginning of Postgame and either loses to Solaris or is not on Reshiram Route, Florinia will not be available as partner at the beginning of Postgame, but she will be available after the player finishes the Lati Quest.
* For Taka to be in the club, the player needs to be either on Zekrom Route, or on Reshiram Route and defeats Solaris on Pyrous Mountain. For Taka to be available as partner, the player needs at least 3 points with him on Zekrom Route, while there is no minimum point requirement if the player is on Reshiram Route and defeats Solaris on Pyrous Mountain.
* For Lin to be in the club and available as partner, the player has to be on Lin Route for postgame, saves her before catching Arceus, and takes her out of the Asylum after catching Arceus. Relationship points with Lin exist, but they don't affect anything.
* Zero is available as partner regardless of what route the player is on. He is also the only partner without any Relationship Points requirement.
==Relationship Point requirements==
The list below shows the minimum number of relationship points the player needs for each character for them to be partners. Special cases for determining certain characters as partners will be noted.

==Trivia==
* This battle mode is the only way to see many of the back sprites of characters you otherwise would not see in the main game or postgame story.
* Taka will have different partner quotes depending if you are on Zekrom or Reshiram Route, his back sprite will also be different as well.
* Cain, Shelly, and Adrienn are the only partners that have a minimum negative relationship point requirement to have them.
** Amaria also has a minimum negative relationship point requirement as well, but only on Zekrom and Mixed Route.
* Anna and Shade are automatic partners on Anna Route, because all the requirements for Anna Route give relationship points with them.
* You cannot have both Anna and Blake as a partner in the same playthrough. This is because Blake needs 3 relationship points to be a partner. The only way to get at least 3 points by the start of postgame is if you give him the Ruby Ring. Anna needs 6 relationship points to be a partner, and you are required to keep the Ruby Ring in order to get her as a partner.
** This means you can get at most 34 out of the 35 partners in the game, only if you are on Lin Route. It is possible to have both Anna and Lin as a partner if you lose to Lin on the third battle with her that leads to the Anna Route.
* Gossip Gardevoir, Sigmund, and Lin are the only characters who have relationship point variables tied to them, yet do not use the variable to determine being a partner.
* It is completely possible to only have Zero as your only partner in Mix ‘n Match if you are on Lin Route. The determination of partners is based on Relationship Points, which you can lose or avoid in the game. This also means you can get no character endings other than the automatic ones, as the relationship point requirements for Mix ‘n Match are lower than the character endings.
** There is also special dialogue if the player does not have anyone to partner up with, which is only possible if the player either did not finish the Cresselia Quest, or start the Reshiram & Zekrom & Kyurem Quest on the Mixed Route or Reshiram Route without beating Solaris on Pyrous Mountain (as well as activating some post game quests that makes some characters absent)“No one available wants to partner up with you…”
