About the Game

Hello and welcome to Pokémon Conquest: Ultimate! This Pokémon Conquest mod took over a year to build and fully overhauls the game from the ground up, making it the most extensive Pokémon Conquest mod to date!

It includes 150 fully evolved Pokémon from Generations 1 to 9 (including regional versions! ), 50 returning Pokémon, and removes the LC and NFE Pokémon that are entirely useless beyond the first 1.5% of the game. This effectively increases the number of fully evolved Pokémon available for use!

The roster has also been adjusted to ensure that all types are represented evenly, from the Pokémon themselves (with a few type alterations to cover previously unavailable type pairings, such as Bug/Dragon Flygon!) to the moves they employ.

Everything from moves (over 100 new ones! ), abilities, Warrior Skills, Pokémon numbers, and more has been rebalanced to make the game more fair, exciting, and strategic.

With 200 fully evolved Pokémon and 200 Warriors, each Warrior now has a unique Perfect Link, and each Warlord now has a “special” Pokémon with which they partner, such as Magoichi with Shaymin-Sky or Kunoichi with Chi-Yu.

The Hero can now “choose” their starting at the start of “The Legend of Ransei,” as they now have access to all seven Eeveelutions.

The difficulty has been significantly increased via a variety of techniques, so don’t be surprised if you lose battles along the road!

Battlefields have been upgraded and will continue to be updated, as new tools and improvements become available!

To provide more information to the player, the in-game text has been upgraded to Gen 9 standards.


  • A completely rebalanced roster!

The days of vanilla Conquest having a million ultra-powerful Fire-type users and only two Flying-type people are long gone! The roster has been completely rebuilt from the ground up, with each type being adequately represented and a reasonably even number of Pokémon using moves of each kind. Obviously, some types are still superior than others (thanks, GameFreak! ), but Ultimate provides a plethora of possibilities for each of them. Furthermore, there are no “duplicate” Pokémon in Ultimate because no two Pokémon share the same type combination or move type. To cover unwanted type combinations, eight Pokémon have had their types modified, including Bug/Dragon Flygon, Ghost/Rock Cursola, and Normal/Steel Dubwool. Weaker Pokémon, like as Beedrill, have had their BST increased to make them usable, and all techniques and abilities have been totally rebalanced to be more fair and enjoyable. This allows any Pokémon, no matter how powerful, to stand out. Each Pokémon has also had its skills chosen from scratch, resulting in better flavour and balance, and has a signature move whenever feasible, such as Ice Ball Walrein, or at the very least a move that is generally associated with it, such as Meteor Mash Metagross or Flamethrower Charizard.

  • 200 fully evolved Pokémon – no LC or NFE Pokémon!

The rebalanced roster includes 200 fully evolved Pokémon, more than doubling the options available in vanilla Conquest! In the original game, LC and NFE Pokémon are only important and useful during the first half of “The Legend of Ransei”, the first of 38 storylines, which is less than 2% of the entire game! Using more than half of the slots on Pokémon that are only useful for less than 2% of the game is a huge waste, so all of those LC and NFE Pokémon have now been replaced by new fully evolved Pokémon. From the start, you will be using and battling fully evolved Pokémon, and all 37 post-game tales have been modified so that foes employ fully evolved Pokémon from the start.

  • 150 new Pokémon – including up to Generation 9!

200 fully evolved Pokémon is more than double what was available in vanilla Conquest, therefore those new fully evolved Pokémon must have come from somewhere! From Generation 1 to Generation 9, 150 new Pokémon have been added, including regional varieties, while 50 Pokémon from the original game have returned. Play with new Pokémon including Alolan Raichu, Starmie, Kleavor, Mamoswine, Breloom, Torterra, Gastrodon, Sigilyph, Ferrothorn, Greninja, Noivern, Decidueye, Kommo-o, Centiskorch, Dragapult, Ceruledge, Gholdengo, and many more! Returning Pokémon include Crobat, Weavile, Metagross, Spiritomb, Haxorus, and others.

  • Every Warrior has a unique Perfect Link!

In vanilla Conquest, Conkeldurr has a Perfect Link with five Warriors! Five! No longer is this an issue in Ultimate as there are 200 Pokémon and 200 Warriors, so every Warrior has a unique Perfect Link! Of course, you are welcome to use other Pokémon as well, as every Warrior now has a 70% max link with every Pokémon that matches their type specialty, giving each Warrior over 35 Pokémon with which to partner. Hopefully, this will lead to a lot of options and variety for the player! Each Warrior has a 0% max link with all other Pokémon that don’t match their type specialty, so delegating your Warriors to find new partners should be much more useful in Ultimate since they cannot link with a bunch of Pokémon with which they have low max links. This makes needing an out-of-game chart less important as it is easy to remember what Pokémon each Warrior links with, but of course, the Pokémon Conquest: Ultimate Database is always available if needed.

  • Every Warlord partners with a “special” Pokémon!

There were 10 legendary or mythological Pokémon for nine Warlords in Vanilla Conquest. Every Warlord in Ultimate has their own unique Pokémon! Motochika’s Keldeo partner, Mitsuhide’s Chien-Pao partner, Yoshihiro’s Galarian Zapdos partner, Keiji’s Great Tusk partner, and many more! All of these unique Pokémon may be found in the story of its partner Warlord following “The Legend of Ransei,” so go find them and become one with some of the most powerful and uncommon Pokémon!

  • Choose your starter!

“The Legend of Ransei” begins with all seven Eeveelutions! After the first tutorial combat, you can visit the info panel and choose whatever Pokémon you want to use to progress through the game. Technically, you can swap between Eeveelutions as frequently as you like throughout the game, but I strongly advise sticking to one Pokémon throughout the adventure or it will quickly fall behind in link percentange. Plus, it’s exciting to stick with a single starting and see it grow and bond with you!

  • Massively increased difficulty!

For the best gameplay experience and maximum difficulty, it is highly recommended that you play WITHOUT items. Items have been completely rebalanced in Ultimate, so if you still wish to use them, you are welcome to do so and they should be more fair (although some are still too strong and there is unfortunately no way to balance them) compared to vanilla Conquest. However, “The Legend of Ransei” has been balanced around you not using any items, with it being very difficult, but still fair, if you do not use any.

  • Rebalanced and more strategic Warrior Skills!

In addition to the previously mentioned Pokémon, moves, abilities, items, and basically everything else, Warrior Skills have also been completely overhauled and rebalanced. In vanilla Conquest, most skills lasted for three turns, making them incredibly uninteresting to use, not to mention very overpowered. The battle would begin, you spend a turn or two moving towards the opposing army, and once the actual battle starts, you spam all your three turn Warrior Skills, reap the benefits forever, and the battle is over. In Ultimate, all Warrior Skills have had their power level reworked, but more importantly, most Warrior Skills now only last for a single turn. This makes deciding when to use it a much more interesting decision. Do you use it to make sure you get it off before you die, but perhaps get suboptimal usage and value out of it? Or do you wait for the optimal moment to use it and get the maximum value, but risk dying and not using it at all? Do you really need something specific on a given turn? Maybe that is the turn to use it! I hope that this will lead to much more fun, interesting, and strategic gameplay as opposed to simply spamming them all as the battle begins, as well as a more balanced gameplay experience.

  • Updated battlefields!

Do you hate playing on Illusio or Valora? In Ultimate, that is a thing of the past (or soon-to-be future lol)! A few of the great Pokémon Conquest modders have begun to work on map editing, and new progress and development is achieved every day. As new or improved maps become available, they will be added to Ultimate to continually make the gameplay experience better!

  • In-game text updated for a better user experience!

Move and ability names have been updated to Generation 9 standards, such as Compoundeyes -> Compound Eyes. All text descriptions have been updated to provide more information to the player, such as the number of turns an effect lasts, while still keeping the ambiguous nature of Pokémon by not giving exact percentages.

Current Limitations

Pokémon Conquest modding is still in its relative infancy compared to the mainline Pokémon games or more popular spinoffs such as the Mystery Dungeon series. We do not have the same tools available to us, and this leads to some unfortunate instances where things cannot be changed exactly how we would like them. However, developments continue to be made all the time, and as progress is made, I will continue to update the game to fix these problems. In the mean time, none of these issues break the game, and it still functions normally and is completely playable!

Wild Pokémon spawns can only be partially edited. This leads to an issue where a lot of Pokémon won’t spawn if a location is at Level 1 or Level 2. For example, if Aurora’s Farm or Ravine are at Level 1, only Cyclizar will spawn. I made every wild Pokémon location Level 3 from the start so that all of the proper Pokémon spawn, but it means there is no need to upgrade these particular locations anymore.

In the second tutorial battle (the first after Oichi joins your army), the wild Kingdra spawns out of bounds due to the fact that it is a hardcoded tutorial battle and the game is not expecting the Level 3 Farm to be loaded (which I had to make happen due to the previous issue I mentioned with the wild Pokémon spawns). The Kingdra cannot be interacted with, which makes this battle unwinnable, but this is not a big issue as you can immediately run from the battle and the game continues on like normal.

Hideyoshi is hardcoded to spawn in the battle in Viperia in “The Legend of Ransei” with whatever is in the Monferno slot. Neither the Pokémon he spawns with nor the link percentage of the Pokémon can be modified at the moment. This is why there is Hideyoshi with a random under-leveled Golurk in that fight.

Nixtrom is messed up and only five enemies are present in the kingdom in “The Legend of Ransei”. I don’t currently know what is causing this or how to fix it. If you want it to be a fair battle, only take five Warriors yourself!

The final “boss” battle (I don’t want to spoil it if you’ve never played before!) in “The Legend of Ransei” is also hardcoded. The same Warlords appear as in vanilla with whatever Pokémon is in the slot of their vanilla Pokémon, and their link percentages also cannot be modified. If this battle seems scuffed to you, this is why!

A few (like the non-Player ♂/♀ Eeveelutions) Perfect Links max out at 99% instead of 100%. There is a bug where if a Warrior or Pokémon has more Perfect Links than they were assigned in vanilla Conquest, the game will repeat the Perfect Link message every time they perform an action, which is very annoying and makes the game unfun to play.

As is the case in all games before Generation 6, there is a shorter character limit for the names of Pokémon, moves, abilities, etc. Some of the more recent Pokémon and moves have names that are longer than the Generation 5 character limit, so they had to be shortened, such as Meowscarada -> Meowscrada and First Impression -> 1st Impression.

Moves can be edited fairly well, although not with full customization yet. Abilities can barely be edited at all.

There are still some Pokémon that we do not have battle sprites for yet, so I have Munchlax subbed in for them. Unlike all of the other limitations, this isn’t a limitation of the current modding capabilities, but rather a limitation of needing people to make the sprites! I can’t add things that don’t exist! If you would like to make battle sprites for any Pokémon we currently don’t have them for or think you can improve on any currently existing sprites, feel free to send them my way and I would be happy to add them to the game!

Still needed: Slowbro-Galar, Slowking-Galar, Samurott-Hisui, Basculegion, Sawsbuck-Spring, Centiskorch, Dracozolt, Quaquaval, Garganacl, Armarouge, Revavroom, Cyclizar, Glimmora, Gholdengo, Zapdos-Galar, Latios, Kingambit, Tornadus-Therian, Thunderus-Therian, Landorus-Therian, Volcanion, Kartana, Marshadow, Naganadel, Regieleki, Chien-Pao

I strongly recommend playing without items for the best and most difficult experience, as that is what the gameplay is balanced around. -Aaron’s Aron
