Since my previous blog dedicated to remakes of Pokémon games became so popular, I've decided to dedicate a new blog to entirely new ideas. Now, to start off, these ideas may mention new generation games, however, this isn't going to be something detailing 100 new species of Pokémon. Potential future generations will be mentioned, but that's all I'll say about them. I might go over some new features I want to see in the games, but as far as new Pokémon, I'll leave those vague.

Series History

Before I focus on the new ideas, I just want to give a refresher on the series' history so far. I will mention both main series titles and spin-offs/side series titles, but only those that are battle simulators and apps compatible with the main series.

Before Generation V, the series followed the staple of Introductory Duo followed by a third Edition, and both Generations III and IV included remakes that followed the tradition of only being based on the original Duo versions, instead of being based on the third Edition. However, Generation V introduced sequels in the place of a third Edition, and skipped remakes entirely. Generation VI included remakes, but didn't have any sort of continuation of X and Y whatsoever, and Generation VII has two follow-up games. And it's been announced that some kind of game is in development for Nintendo Switch, but nothing else is known about it other than the fact it may be a main series title instead of a spin-off. With those in mind, I want to suggest ideas for how I'd like to see the series move forward, aside from obvious future generations and remakes.

Generation I:

  • Paired versions Pokemon Red and Pokemon Green launched in Japan.
  • Due to technical issues, a third version, Pokemon Blue, was released that fixed some of the issues in Red and Green
  • Pokemon Red and Pokemon Blue were released outside of Japan, using the Japanese Blue as a template
  • Pocket Monsters Stadium launched in Japan, allowing players to battle their Pokemon from Red, Green, and Blue in 3D for the first time. The available Pokemon that could be used in-game was limited to 42, instead of the original 151.
  • Pokemon Yellow, an enhanced edition of Red and Green/Blue, added in elements from the Pokemon anime to the story of Red and Blue/Green
  • Pokemon Stadium, known as "Pocket Monsters Stadium 2" in Japan, launched internationally. It included a NIntendo 64 Transfer Pak accessory, and allowed players to battle their Pokemon on the big screen, trade between multiple games and Transfer Paks, move their Pokemon from the Game Boy games to the Nintendo 64 or move them between different games without trading, and copy their Pokemon to be used in the in-game Stadium battle mode. The game also allowed players to play their copies of Red, Blue, Green (Japan only), and Yellow on their TV through the Transfer Pak.

Generation II

  • Paired versions Pokemon Gold and Pokemon Silver launched
  • Pokemon Stadium 2, known as "Pocket Monsters Stadium: Gold and Silver" in Japan, launched for the Nintendo 64. Much like it's predecessor, it could communicate with Red, Blue, Green (Japan), and Yellow, allowing players to battle, trade, and emulate their games on the big screen. Additionally, it supported the new generation of games, allowing players to do the same with their copies of Gold and Silver. 
  • Pokemon Crystal, an enhanced retelling of Gold and Silver launched. It was compatible with Stadium 2, despite being released after it.
  • Gold, Silver, and Crystal could trade with Red, Blue/Green, and Yellow through the time capsule feature, allowing older Pokemon to be transferred to the new Generation
  • With the time capsule, Pokemon captured in Generation II games could be sent back to Generation I provided that they are Pokemon that can be captured in Generation I, and do not know any new moves introduced in Generation II. For obvous reasons, Generation II Pokemon cannot be sent to a Generation I game. This same limitation was applied in Pokemon Stadium 2, preventing Gen II Pokemon or those who know moves intruduced in Gen II from being transferred between games.
  • Though marketed as Game Boy Color games, Gold and Silver could be played on an original Game Boy. Crystal was, however, exclusive to the Color.

Generation III

  • Paired versions Pokemon Ruby and Pokemon Sapphire launched, compatible only with the Game Boy Advance family of systems
  • Games from Gens I and II could not connect to Ruby and Sapphire, making transferring older Pokemon impossible. 
  • Pokemon Box: Ruby and Sapphire released for the Nintendo GameCube. It served as a way to transfer Pokemon between Ruby and Sapphire without trading, and also allowed players to play Ruby and Sapphire on their TV through the GameCube, as the Stadium series had done with the first two Generations.
  • Pokemon Colosseum released for the GameCube, included a cable to link a player's GBA to their GameCube, and unlike the Stadium series, featured a story mode similar to the handheld games. This game could connect to Ruby and Sapphire, allowing players to trade Pokemon between those captured in the game's story mode and those captured in the handheld games. As with Stadium, the game also featured a Battle Mode that allowed players to battle each other on the big screen by connecting their GBA systems to the GameCube with a Pokemon game included. This game also remedied the unavailability of a number of Johto Pokemon, such as Ho-Oh, Entei, Suicune, and Raikou, by making them catchable in-game and able to be traded to the GBA games.
  • Pokemon FireRed and Pokemon LeafGreen, remakes of Red and Green/Blue, launched, to remedy the unavailability of Gen I Pokemon in the new games. The games were compatible with Colosseum despite being released months later, complete with their own models in Battle Mode.
  • Pokemon Emerald, an enhanced retelling of Ruby and Sapphire, launched. As with FireRed and LeafGreen, it was also compatible with Colosseum, despite being released a year later. Because of this, Brendan and May recycle their Ruby/Sapphire models in Battle Mode. 
  • Pokemon XD: Gale of Darkness, a follow-up/sequel to Colosseum, released. As with Colosseum, it can communicate with Ruby, Sapphire, FireRed, LeafGreen, and Emerald, allowing players to battle their GBA Pokemon on the big screen, and trade with XD. Trainers from the handheld series recieved updated character models, with those from Pokemon Emerald being rendered in their appropriate designs, rather than reusing their Ruby/Sapphire models. This game also included new Pokemon to be captured, including a special Lugia that knows Psycho Boost.
  • With the release of the Game Boy Player adapter, players were able to play all of their Pokemon games through their GameCube.

Generation IV

  • Paired versions Pokemon Diamond and Pokemon Pearl launched
  • With Pal Park, transferring Pokemon from Ruby/Sapphire/Emerald and FireRed/LeafGreen made cross-Generation connectivity possible again. However, unlike with Gen II and Gen I, Pokemon from Gen III could not return if sent forward to Gen IV, and Pal Park could only be used once every 24 hours. 
  • MyPokemon Ranch, a Nintendo WiiWare title, was released, serving a similar fuction to Pokemon Box: Ruby and Sapphire, allowing players to move their Pokemon from their DS games without trading. 
  • Pokemon Battle Revolution released for the Wii, serving as a spiritual successor to Pokemon Stadium, allowing players to connect their DS games to the Wii and copy their Pokemon to be used in-game, as well as battle their DS parties on the big screen with the DS Battle Mode, rendering Lucas and Dawn in 3D. Also like the Stadium series, players could unlock Mystery Gifts as they progress through Colosseum Mode, which could be transferred to the DS games. Some of these included rare items and Pokemon, such as an Electrivire, Magmortar, and surfing Pikachu.
  • Pokemon Platinum, an enhanced retelling of Diamond and Pearl, launched. It was fully compatible with Battle Revolution, however, Lucas and Dawn would recycle their original models instead of their updated designs. The Japanese version also had compatbility with MyPokemon Ranch, however, the international version did not.
  • Pokemon HeartGold and Pokemon SoulSilver, remakes of Gold and Silver, launched. These games finally fixed the 24 hour limit on Pal Park, giving players unlimited usage per transfer. As with Platinum, these games were compatbile with Battle Revolution. Also like Platinum, due to being released afterward, Ethan and Lyra did not have unique character models in DS Battle Mode as Red and Leaf had in the GCN series, and recycled Lucas and Dawn's Diamond/Pearl designs.
  • With the release of the Nintendo DSi, Pal Park can no longer be used unless the player owns a DS system with a Game Boy Advance slot

Generation V

  • Paired versions Pokemon Black and Pokemon White launched
  • With the Poke Transfer feature, Pokemon from Generation IV, and by extension, Generation III, can be sent forward to Generation V. However, this feature can only be used if the player has at least two DS systems in their possession
  • PokeDex 3D launched for the Nintendo 3DS. It was a free app that displayed 3D models of the Pokemon found in the Unova PokeDex in Black and White. PokeDex entries were unlocked daily or via reading QR codes, and only a few were available from the start.
  • Pokemon Black 2 and Pokemon White 2, sequels to Black and White, launched. 
  • PokeDex 3D Pro launched, replacing the original entirely. Unlike PokeDex 3D, Pro was a paid application. Addtionally, it now displayed all 649 Pokemon at the time, including new forms introduced in Black and White 2, and every PokeDex entry was unlocked by default.
  • Pokemon Dream Radar app launched for the Nintendo 3DS system, which allows players to catch additional Pokemon that would be transferred to their copy of Black 2 or White 2, all of which had their hidden ability. Additionally, the legendary mascots of Diamond, Pearl, Platinum, HeartGold, and SoulSilver can be caught and transferred to the Gen V sequels if the player has them in the 3DS when the application is launched

Generation VI

  • Paired versions Pokemon X and Pokemon Y launched
  • The 3DS apps PokeTransporter and Pokemon Bank are released, which allow players to transfer Pokemon from Generation V, and by extension, Generations III and IV, to Generation VI.
  • Pokemon Omega Ruby and Pokemon Alpha Sapphire, enhanced remakes/reboots of Ruby and Sapphire, launched
  • Pokemon Red, Green (Japan), Blue, and Yellow launched on the Nintendo 3DS Virtual Console

Generation VII 

  • Paired versions Pokemon Sun and Pokemon Moon were released
  • An update to Pokemon Bank was released to allow compatibility with Sun and Moon. Likewise, added compatibility with the 3DS versions of Red, Blue, Green (Japan), and Yellow allow Gen I Pokemon to be transferred to Sun and Moon, however, they cannot be deposited in Generation VI games.
  • Pokemon Bank also allows players to transfer Pokemon from X, Y, Omega Ruby, and Alpha Sapphire to Sun and Moon, and by extension, transfers from Generation V games through PokeTransporter make a direct transfer from a game two Generations in the past possible for the first time in series history.
  • Alternative paired versions, Pokemon Ultra Sun and Ultra Moon, were released. Like with previous enhanced versions, they tell a story that is mostly identical to Sun and Moon, with some notable changes and a rewritten final act and expansive post-game. They are able to trade and battle with Sun and Moon with the same limitations as connectivity between XY and ORAS, blocking new Pokemon, new forms, moves, abilities, and items that didn't exist in the originals, and defaulting custom character designs to the generic looks of the trainers in Sun and Moon when battling and trading. 
  • Pokemon Gold and Silver were released for the Nintendo 3DS, akin to Red, Blue, Green, and Yellow, and were made compatible with Pokemon Bank, allowing Generation II Pokemon to be transferred to Sun, Ultra Sun, Moon, and Ultra Moon, bringing the series full circle. Additionally, with the Time Capsule feature and wireless trading of the Nintendo 3DS, these games can trade with the 3DS ports of Red, Blue, Green, and Yellow. 
  • A mainstream Pokemon game is being developed for the Nintendo Switch, though nothing is known about it.

My Predictions:

Partially more of a wishlist than actual predictions, these are my speculations on the remainder of Generation VII, as far as main series titles are concerned.

  • Future Pokemon games will be made for the Switch (confirmed), which will remain compatible with every generation of Pokemon through the use of Bank and Transporter, and the virtual console ports of Generations I and II (not yet confirmed).
  • Pokemon Bank and Transporter would be released on Nintendo Switch. Owners of a Nintendo 3DS system that have an active Pokemon Bank license will be able to use the same account on their Nintendo Switch by linking their existing Nintendo Network ID to the My Nintendo service.
  • Pokemon Temporal Diamond and Celestial Pearl will be made, and will be able to trade and battle with Pokemon for Nintendo Switch. Unlike with ORAS and USUM, they will introduce new features and Pokemon forms that did not exist in Pokemon for Nintendo Switch, however, Pokemon Switch will recieve a title update that makes it compatible with the new content. 

New Ideas

Now, I can move onto my new ideas.

Amiibo Functionality

Nintendo's amiibo have risen in popularity a lot since they were first released three years ago, with a large number of games including fuctionality with the Big N's series of collectible figures and cards. Even third-party games, such as the Mega Man Legacy Collection and The Elder Scrolls V: Skyrim, have added amiibo features for their Nintendo ports. Several of Nintendo's flagship franchises, namely Super Smash Bros, Mario, The Legend of Zelda, Fire Emblem, Pikmin, Animal Crossing, and Metroid have seen amiibo compatibility. However, despite being one of Nintendo's biggest franchises, the Pokemon series has not seen amiibo functionality outside of Pokken Tournament, even though Pokemon Rumble U for the Wii U was the very first Nintendo exclusive game to use NFC figures. With that being said, I think the Pokemon franchise should implement some sort of amiibo functionality in future games. The first (official) games that I'd like to see support this feature are Ultra Sun and Moon and Pokemon for Nintendo Switch.

Pokemon amiibo
  • The first form of amiibo functionality I'd suggest is in the form of Mystery Gifts, activated when scanning Super Smash Bros series Pokemon amiibo. This would give the player the Pokemon that the figure represents, complete with a held item and their hidden ability. By default, they are all at level 50, and will be marked with a special symbol, similar to the one used as the Super Smash Bros logo, indicating that they represent the Pokemon from Super Smash Bros., much like how Pokemon transferred from Gen I games to Sun and Moon have a Game Boy icon. Greninja would have the Battle Bond ability. All Pokemon's OT are set as "Smash" and their summary reads as "Met in a Distant Land".
    • Charizard holds Charizardite X
    • Lucario holds Lucarionite
    • Mewtwo holds Mewtwonite Y
    • Pikachu holds Pikashunium Z
    • Jigglypuff holds an all-new Z-crystal called Puffium Z. Its Z-move is similar to its Final Smash.
    • Greninja holds an all-new Z-crystal called Greninjium Z. Its Z-move is a giant golden Water Shuriken, like the one Ash's Greninja used in the anime.
  • Additionally, the Shadow Mewtwo card from Pokken Tournament would net the same result, gifting players a Shadow Mewtwo at level 70, holding Mewtwonite X, with a unique ability. In the same vein as Partner Cap Pikachu, Shadow Mewtwo cannot be traded to Sun and Moon, however, it is obtainable in Ultra Sun, Ultra Moon, and Pokemon Switch. Its OT is set as "Pokken" and its summary reads as "Met in the Ferrum Region". It would have a unique crystal-shaped icon.
  • The release of Pokemon Switch would be met with a series of amiibo known as the Pokemon Trainer series. These figures would be modeled after the playable characters in the Pokemon series. 
  • The launch of the Pokemon Trainer series amiibo would be met with a free-to-download 3DS app called Pokiibo. The function of Pokiibo would work in a similar method to Pokemon Bank. It would read the data of any Pokemon game on your 3DS system before allowing you to use it, and would allow you to copy a team of Pokemon to a trainer card from either your party or any of your PC boxes. Unlike Pokemon Bank, which only allows moving Pokemon from Gen VI and VII games, Pokiibo would allow you to copy your Pokemon from any Generation VI, VII, I, or II game on your 3DS. Once a trainer card has been set, it can be copied to a Pokemon Trainer series amiibo. Similar to the custom moves for Super Smash Bros fighters, the teams can be changed and rearranged at any time through the app. However, Pokemon teams can only be written to the figure of the trainer that represents the hero of their respective game.
Pokiibo Logo
  • The first wave of Pokemon Trainer amiibo would include the trainers from Sun/Moon, Ultra Sun/Moon, Red, and Gold. The second wave would include trainers from Pokemon Switch, XY, and Omega Ruby/Alpha Sapphire. All trainers would be available in dual packs, except for Red and Gold, who would be packaged individually, and the trainers from the Switch game, which are unknown at this time. The list of trainers and their compatible games are as follows:
    • Red: Pokemon Red, Blue, Yellow, and Green (Japan only)
    • Gold: Pokemon Gold and Silver
    • Calem/Serena: Pokemon X and Y
    • Brendan/May: Pokemon Omega Ruby and Alpha Sapphire
    • Sun/Moon: Pokemon Sun and Moon
    • Sun/Moon (US/UM): Pokemon Ultra Sun and Ultra Moon
  • For trainers from X, Y, Sun, Moon, Ultra Sun, and Ultra Moon, the appearance of the trainer's model will appear the same as your chosen character. If players assign a team to a Serena amiibo while their in-game character is the male trainer, she will take on the appearance of the rival Serena instead. With the trainers from the Alola series, the opposite gender trainer will just be rendered in their default design, reflective of your chosen character's skin tone and hair color.
  • The Pokemon Trainer amiibo can only be scanned into Ultra Sun/Moon, Pokemon Switch, and future games, and are not compatible with Generation VI games or the original Sun and Moon. Once scanned, the amiibo will unlock its respective trainer with the team you assigned to them as an opponent in both Champion Title Defense and VS Recorder mock battles, allowing players to battle Pokemon from across 4 different generations within the same game. In-game, scanning the amiibo will unlock an event where the Rotom Dex tells the player that they recieved a letter from an unknown trainer who wants to challenge them to a Champion Title Defense battle. When they arrive at the Pokemon League, the chosen amiibo will automatically be their opponent after they beat the Elite Four. This means that players that scan a Red amiibo will face the character in his Generation I appearance, rather than his new appearance in Alola.
  • In my ideas for a new Pokemon Stadium successor, the amiibo scanned can be used in free battle, allowing players to actually play as the character the amiibo represents, and create their own match-ups. Generation II Gold and Generation I Red vs Generation VI May and Serena? Calem vs Moon? etc.
  • Pokemon Temporal Diamond and Celestial Pearl would utilize amiibo the same way as Ultra Sun and Moon, allowing players to battle trainers from other regions instead of rebattling Cynthia. The launch of these games would be met with a Wave 3 of Pokemon Trainer amiibo, which would include Lucas and Dawn in their new designs, as well as Kris to promote Pokemon Crystal releasing on the eShop, and the Generation V trainers. All trainers except for Kris would be available in dual packs. The new amiibo and their compatible games would be as follows:
    • Lucas/Dawn: Pokemon Temporal Diamond and Celestial Pearl
    • Kris: Pokemon Crystal
    • Hilbert/Hilda: Pokemon Black and White
    • Nate/Rosa: Pokemon Black 2 and White 2
  • After the release of Wave 3 of the Pokemon Trainer series, Pokiibo would recieve an update to make it compatible with Generation V games: Black, White, Black 2, and White 2.

Game Ideas

I have four primary game ideas to cover. Though I have several other ideas to take note of, these four are the primary examples.
Pokerman Ideas
  • Stadium Revival: A series that began on Nintendo 64, the Stadium series was developed in order to see your Pokemon on the big screen, and had its share of bonuses, such as mini-games and mystery gifts. Though it is unlikely at this point in time, I still want to see the Stadium series return. Even back on the Wii, I wanted a sequel to Battle Revolution.
  • Remakes: I have an entire blog dedicated to this, though in this blog, my primary focus will be on remakes that I actually expect to see in the near future. Those, and potential other ideas that could be made a reality.
  • Console RPG: These are actually original ideas of mine that are spiritual successors to the GameCube games, but also cross over into the mainstream series. The concept actually began as early as 2011, but since then I've refined and rebooted my original ideas into a different scenario altogether. I have a pair of games planned, which are continuations of each other.
  • Fighting Games: I know we have Pokken Tournament to classify into this category, though even if it's a fun game, I would want to see a Pokemon fighting game that plays more like a traditional fighter, rather than the 3D arena brawler we have with Pokken. A couple fighting games that come to mind are Persona 4 Arena and Dragon Ball Z: Extreme Butoden.

Stadium Games

The Stadium series is one of my favorites in the Pokemon spin-offs.

Battle Revolution 2

This idea has been abandoned for a while, but back when Generation V was still new I had hoped for a sequel to Battle Revolution. Even though it'll never happen now, I still want to share the ideas I had at the time and a few I've added.

  • It would be released for the Nintendo Wii. Though my mock-up boxart was designed for Wii U, I think that had the game been developed, it would have been made for the same console as its predecessor. 
  • The game would be released before Black 2 and White 2, though it would still be compatible with them. Like its predecessor, the game would be able to distribute Mystery Gifts to the DS games. However, unlike the first Battle Revolution, these would only be compatible with Generation V games.
  • Like its predecessor, the game would have multiple save files, and allow players to copy their DS Pokemon to the Wii, scanning their party and PC boxes by linking to their DS games. It would be able to copy Pokemon from both Generations IV and V, however, only one game may be used per save file.
  • A new feature would allow players to use their DS game's protagonist as an avatar for their Trainer Cards, and the trainer customization would be improved from the previous game, allowing more trainer templates with different hair styles.
  • DS Battle Mode would be improved to be compatible with every main series game released on the Nintendo DS. As such, every trainer would have their own unique 3D models in Battle Mode, with Lucas and Dawn having separate designs for Diamond/Pearl and Platinum, Ethan and Lyra reflecting on their designs from HeartGold/SoulSilver, and Hilbert/Hilda being rendered in 3D.
  • Despite being released before the Black/White sequels, Nate and Rosa would have their own models in DS battle mode, and Black/White Kyurem, the Kami trio's Therian formes, and the form changes for Meloetta and Keldeo exist in the game too.
  • Similar to Pokemon Stadium 2, Generation IV and Generation V games would be able to battle with each other in DS Battle Mode, since the DS games would connect to Battle Revolution to be used as controllers, rather than relying on their native connectivity with each other.

Stadium 3

The official sequel to Stadium 2, this game would be released shortly after Omega Ruby and Alpha Sapphire​, and would be a callback to the original Stadium games, functioning in much the same manner.

  • The game would be able to connect to XYOmega Ruby, and Alpha Sapphire. As with the original Stadium games on the Nintendo 64, connecting to the 3DS games allows players to register Pokemon from either their party or PC boxes to be used in Stadium challenges, Gym Leader Castle, and Free Battle Mode.
  • In order to connect the Generation VI games to Stadium 3, a free app would be released on the Nintendo 3DS, called Transfer Pak, as a callback to the accessory used in the original series. Much like Pokemon Bank, it would check your 3DS for compatible games and then display your party and PC storage, allowing you to choose Pokemon from anywhere in your game to be resgistered.
  • Like in Battle Revolution before it, Pokemon can be resgistered to Trainer Cards, and as with Battle Revolution 2, players can select the hero from their respective game to be used as the Trainer Card's avatar. Unlike in the Battle Revolution games, Pokemon from multiple games can be registered under the same profile, as with the original Stadium games. Additionally, if players connect multiple 3DS games to Stadium 3, they can battle and trade between them in the same manner as the original Stadium games. However, like with Stadium 2's restriction of trades between Generations I and II, the same trade restrictions between XY and ORAS still exist in Stadium 3.
  • There would be two Gym Leader Castles for trainers to challenge, one based on the Kalos Pokemon League, and the other based on the Hoenn Pokemon League. Players that clear either Gym Leader Castle with Pokemon registered from their respective games (XY for Kalos, ORAS for Hoenn), would unlock special Pokemon. 
  • As with the original games, the GB Tower and Pokemon Lab return. The GB Tower is renamed the 3D Tower, and allows players to play their 3DS Pokemon game on the big screen, with the TV reflecting on the top screen of the 3DS, and the Wii U Gamepad reflecting on the touch screen, though the touch screen features can also be used on the 3DS itself. The Pokemon Lab feature allows players to view their Hoenn or Kalos PokeDex in HD, and also serves as an alternative to Pokemon Bank, allowing players to move their Pokemon between Generation VI games without trading them. The feature would also allow players to simulate a trade when depositing Pokemon so that Pokemon that only evolve via trading may be evolved by players who only own one 3DS. 

Stadium Ultra

The follow-up to Stadium 3 that would be released for Nintendo Switch. Many features return, although some have undergone changes.

  • The game would be able to connect to SunMoonUltra Sun, and Ultra Moon, allowing players to register Generation VII Pokemon for use in the game's Battle Modes.
  • Additionally, the Transfer Pak app would recieve an update that not only makes it compatible with the Generation VII games, but also Generation V and the virtual console versions of the Generation I and II games. With the update to the Transfer Pak app, Stadium Ultra would be compatible with XYOmega RubyAlpha Sapphire, BlackWhiteBlack 2White 2RedBlueYellowGold, and Silver
  • As with Battle Revolution 2, the game's Mystery Gifts are only compatible with the Generation VII games.
  • Gym Leader Castle is updated and features the return of Kanto and Johto gym leaders to accomodate conectivity with Generations I and II. Clearing the Kanto challenge with a team from Generation I games will award the player a surfing Pikachu, and clearing the Johto challenge with a Generation II team awards the player a shiny Lugia on the first clear and Ho-Oh on the second clear. 
  • The Kalos and Hoenn Gym Leader Castles from Stadium 3 return.
  • To accomodate connectivity with Generation V games, a Pokemon World Tournament mode would be added, unlocked after clearing any of the Gym Leader Castle or Stadium challenge modes for the first time. Gym Leaders from Sinnoh and Unova, Kahunas from Alola, and notable trainers, such as Wally, Anabel, Zinnia, N, Maxie, and Guzma, etc, take part in it. Clearing the Pokemon World Tournament with Pokemon from Black and White awards players a hidden ability Volcarona, while clearing it with Black 2 or White 2 will award players with the opposite shiny Pokemon awarded from Black Tower/White Treehollow. Black 2 players get a shiny Dratini while White 2 players get a shiny Gible.
  • Mini-games are revamped in the new Island Challenge Mode. This mode reflects on Alola's Island Challenge and offers a variety of mini-games and challenges that correspond to events in Sun and Moon, such as Schooling WishiWashi, a self-explanatory game, and General Gumshoos, a game that involves a Gumshoos defeating waves of Alola Rattata.
  • Upon the release of Pokemon Temporal Diamond and Celestial Pearl, both Stadium Ultra and Transfer Pak would be updated to be compatible with the Sinnoh remakes, making Pokemon Stadium Ultra the first battle simulation game in the series to (technically) be compatible with all 7 generations.
    • A new branch in Pokemon World Tournament would be added, giving new teams to the Sinnoh Gym Leaders and Cynthia to accomodate their appearance in the Sinnoh remakes.
  • The game's Free Battle Mode allows players to use their parties from any of their 3DS, Generation V, or virtual console Pokemon games. As such, every trainer has their own unique 3D model that is reflective of their source game. As with Battle Revolution 2 and Stadium 3, all of these trainers can also be used as avatars for Trainer Cards when registering Pokemon. As mentioned in my amiibo section, Stadium Ultra would be compatible with the Pokemon Trainer series amiibo, which would unlock amiibo trainers as selectible Trainer Cards and Free Battle opponents.
    • Red takes on his design from RedBlue, and Yellow. His FireRed/LeafGreen design can be unlocked as a Trainer Card avatar by clearing Kanto's Gym Leader Castle. His Sun/Moon design can be unlocked by clearing Pokemon World Tournament with a team registered from a Kanto game.
    • Ethan/Gold takes on his design from Gold and Silver. His HeartGold/SoulSilver design can be unlocked as an avatar for custom Trainer Cards by clearing Johto's Gym Leader Castle.
    • Brendan and May use their designs from Omega Ruby and Alpha Sapphire. Their original Ruby/Sapphire and Emerald designs can be unlocked by clearing Hoenn's Gym Leader Castle.
    • Hilbert and Hilda use their designs from Black and White
    • Nate and Rosa use their designs from Black 2 and White 2. Their various PokeStars Studios outfits can be unlocked by clearing the Pokemon World Tournament.
    • Calem and Serena's designs are taken from copies of X and Y. Their designs reflect on however players have customized them in X or Y. Their NPC rival designs can be unlocked by clearing Kalos' Gym Leader Castle.
    • Sun and Moon's designs are entirely player-specific, and their designs will reflect on any customized appearance players have given them in SunMoonUltra Sun, and Ultra Moon.
    • Lucas and Dawn would utilize their designs from Temporal Diamond and Celestial Pearl, which would also offer customization like XY and Sun/Moon. Their original Diamond/Pearl and Platinum costumes/designs can be unlocked by clearing any Stadium or Gym Leader Castle with Pokemon registered from a Sinnoh game.
  • The Pokemon Lab would be updated and split into three modes: Classic, Unova, and Modern. All three styles have a Pokemon Trading Simulator so that players that only own one game or 3DS system can evolve Pokemon that only evolve via trading.
    • Classic Mode, like the one in the original Stadium games, would serve as a Pokemon Bank styled storage for Pokemon from Generation I and II games, which can be freely moved between games following the same limitations as the Time Capsule trading feature (no trading Johto Pokemon or Generation II moves to Gen I, etc.). Additionally, only the Generation I and II games can be used in this mode. As with the original games, players can also view the Kanto and Johto PokeDexes in 3D when a Generation I or II game is connected. 
    • Unova Mode, as the name indicates, would offer the same features for the Generation V games, allowing players to view the Unova Pokedex in 3D and move Pokemon between games without trading. The same limitations that existed in Generation V for trading carry over (No moving Black/White Kyurem, or the Therian forms of Tornadus, Thundurus, and Landorus, etc.). As with Classic Mode, only the Generation V games can be used in this mode.
    • Modern Mode works similarly to the Pokemon Lab of the previous game. In addition to being compatible with X, YOmega Ruby, and Alpha Sapphire, it is also compatible with SunMoonUltra Sun, and Ultra Moon. Transferring Pokemon between 3DS games has the same limitations  as Pokemon Bank, preventing Pokemon with new moves introduced in ORAS from being transferred to XY, and preventing any Pokemon generated in Generation I, II, or VII from being sent to XY or ORAS. and preventing the transfer of Black/White Kyurem and automatic bagging of Z-Crystals. However, unlike with Pokemon Bank, Mega Stones can be transferred between games, such as a Lucarionite from X being transferred to Omega Ruby, or Houdoominite from Sun being transferred to Ultra Moon. The only limitation is that Mega Stones cannot be moved from Generation VI to Generation VII or vice-versa. As with Pokemon Bank, a Transporter PC is available in Modern Mode that allows Pokemon from Generation V to be transferred to Generations VI and VII, and Pokemon from Generations I and II to be transferred to Generation VII. As with the Transporter App on 3DS, Pokemon transferred cannot return to their game of origin, and will automatically be stored in the Stadium Ultra Pokemon Storage.
  • The GB Tower returns again, this time simply referred to as the Game Tower. The Game Tower has three modes: GB Tower, DS Tower, and 3D Tower. As with Stadium 3, the 3D Tower allows players to play their 3DS games through their Nintendo Switch, which is now compatible with Generation VII games. The GB Tower, like in Stadium 2, allows players to play their Generation I and Generation II games on the Switch, and the DS Tower allows players to play Generation V games.

More to be added later...
