>>PLAY THE MOD HERE<<

Hello all! Welcome to Kanto Expansion Pak (KEP)
Kanto Expansion Pak is an RBY SoloMod that aims to remain faithful to core RBY mechanics whilst also adding new life to it with the introduction of scrapped Pokémon, cross-generational evolutions, and regional variants. New types and moves for those types have also been introduced to further integrate the new Pokémon into the mod. True to the mod's name, no former Pokémon will receive changes. Our primary goal is to expand OU's pool of options while leaving it with an element of familiarity.

Featuring:

  • 22 new scrapped Pokémon.
  • The evolutions and pre-evolutions of every Kanto Pokémon receives them from later generations.
  • Regional variants of every Kanto Pokémon that receives one from later generations.
  • 3 new types (Dark, Steel, Fairy) and an updated type matchup chart from the first demo of GSC.
  • 21 new Dark, Fairy, and Steel type moves that are mechanically compatible with RBY (share a similar effect to moves already in the code.)

  • Species Clause: No two Pokemon of the same species.
  • Evasion Clause: Minimize and Double Team are banned.
  • OHKO Clause: Horn Drill, Guillotine, and Fissure are banned.
  • Endless Battle Clause: Endless Battles will result in a tie (eg. Two Transform Pokemon in a last-Pokemon situation)

That's right folks! KEP v1.3 is just around the corner!
With the introduction of several new Kanto-adjacent Pokémon from Scarlet and Violet, KEP will have it's first Pokédex update since the mod's inception. But we aren't just adding the S/V mons, either. Due to popular demand, Melmetal and Meltan have been added!

The update will become available as soon as Gen 9 is implemented on Dragon Heaven. In the meantime, you can join the Official KEP Discord Server, or check out the KEP Spreadsheet if you're just getting into the meta.

Overall changelog;
- Adds Gen 9 Kanto-likes: The three Tauros breeds, Scream Tail, Sandy Shocks, Toedscool/Toedscool, Wiglett/Wugtrio, and Annihilape.
- Adds Meltan and Melmetal from LGPE following the in-server vote. Special was chosen based on how little it uses its SpA in modern, and how its BST pans out, which is...very high either way.
- Galarian Zapdos gets +10 Special to revert a nerf from 1.0 that was designed to put it in line with the other bird's BST, not knowing they are different in mainline anyway (lol)
- Minorly buffs Omega by adding Surf to its movepool, being consistent with Gyaoon and the Kaiju fight theming.
- Adds Kowtow Cleave and gives it to Ribbito and Croakazuna. Probably not good, as they have Night Slash already.
- Adds Shelter and Ruination, albeit as unused moves. Added for the same reasons as Dark Void and Nature's Madness: they have Gen 1 effects, there's just nothing that would be an applicable addition. It technically adds moves to the Metronome pool; Kinesis could be called prior to being learned in Yellow.

As a final note, huge shoutouts to Albatross and Martha's Against Humanity from the Discord for making the new sprites! It's absolutely incredible and your hard work has not gone unnoticed!

KEP v1.3 is now live!

Sorry about the delay. It was originally planned to be rereleased alongside the pet mods server updating to Gen 9, but the update was taking so long that it was decided to just remake KEP 1.3 to work without needed the Gen 9 server update.

There are plans for an individual tour to start after everyone adjusts to the new meta. Until then, have fun with all the additions!

  • Adds Gen 9 Kanto-likes: The three Tauros breeds, Scream Tail, Sandy Shocks, Toedscool/Toedscool, Wiglett/Wugtrio, and Annihilape.​
  • Adds Meltan and Melmetal from LGPE following an in-server vote. Special was chosen based on how little it uses its SpA in modern, and how its BST pans out, which is...very high either way.​
  • Galarian Zapdos gets +10 Special to revert a nerf from 1.0 that was designed to put it in line with the other bird's BST, not knowing they are different anyway (lol)​
  • Totartle HP 70 -> 79, DEF 65 -> 85, finally fixing a long-standing issue with stats.​
  • Minorly buffs Omega by adding Surf to its movepool, being consistent with Gyaoon and the Kaiju fight theming.​
  • Perrserker now learns Hyper Beam.​
  • Adds Kowtow Cleave and gives it to Ribbito and Croakazuna. Probably not good, as they have Night Slash already.​
  • Adds Shelter and Ruination, albeit as unused moves. Added for the same reasons as Dark Void and Nature's Madness: they have Gen 1 effects. It technically adds moves to the Metronome pool; Kinesis could be called prior to being learned in Yellow.​
  • New front/back sprites for Alolan Raticate, Alolan Golem, Alolan Marowak, Alolan Raichu, Alolan Persian, Alolan Exeggutor, Galarian Slowbro, Galarian Weezing, Galarian Rapidash, Alolan Ninetales, Scizor, Magnezone, Blissey, Sirfetch'd, Politoed, Perrserker, and Mr. Rime. I may have missed one or two.​
  • Galarian Birds have new, properly-sized back sprites; Steelix and Slowking have new RBY-ified ones.​
  • Blastyke's sprite has been made 96x96 rather than 92x92, a minor error that caused issues when mass resizing and stuff like that.​
  • Magikarp Jump forms were added because Albatross is unhinged.​
  • Backend stuff for the Hisui content has been optimised​
The following Pokemon will be placed in OU, the rest UU:
Cryithan, Omega, Trampel, Deer, Madaamu (edge case), Slowking, Tangrowth, Rhyperior, Galarian Articuno, Galarian Zapdos

This will be alongside the usual OU list:
Alakazam, Chansey, Cloyster, Exeggutor, Gengar, Jolteon, Jynx, Slowbro, Snorlax, Starmie, Zapdos

Lapras and Victreebel will be dropped to UU in accordance with what's currently going on in RBY UU, as right now they're in the OU by Technicality limbo without any actual reason to keep them there. The list is outdated.

Note that this isn't necessarily a "real" tier change, it is being done from a builder perspective to promote what's been shown to be effective so far. The next update adds a bunch of Pokemon to "New" (Three Tauros, Sandy Shocks, Scream Tail, Annihilape, Toedscruel, Wugtrio) which then further pushes the rest of the OU contenders out; this bloat is undesirable.

KEP v1.31 is now live!
(For two months already)

It's been a while since the last post. Truth be told, I was pretty lazy and procrastinated making this for a while. But no more!

This updates adds the Carapthor line and Taaban; Carapthor being the scrapped beetle design for Beedrill, Taaban being the "spiral Shellder" of Slowbro from SW97. There have also been numerous tiering changes based on feedback from the last tournament.

  • Scream Tail from New to Uber
  • Toedscruel from New to Uber
  • Melmetal from New to OU
  • Annihilape from New to OU
  • Sandy Shocks from New to OU
  • Wugtrio from New to UU
  • All Tauros forms to UU

Kanto Expansion Pak v. 1.4 is now live on Showdown!

We're finally back, and on a new server too! KEP has finally migrated to the new Pet Mods Pokemon Showdown server. From this point forward, the dragonheaven client will no longer be receiving updates. The new server will make updating the mod a lot easier.

We've also made a ton of progress on our ROM hack! We even released a promotional trailer for it which has reached nearly 70k views! Holy moly! If you want to receive updates on the mod or just talk about it in general, join the KEP Discord server.

Changelog:

Anyways, here are the new changes to the mod. They include new balance changes as well as many bugfixes. Notable changes for OU have been bolded.
  • Tradebacks are now allowed in all KEP tiers following a 50-6 vote in the KEP server a few months ago.
  • Updates all front and back sprites to synchronise with the Kanto Expansion Pak ROM Hack. This includes Yellow-style sprites for the beta Pokemon by RacieBeep.
  • Pokemon icons for prototype Pokemon have been revised and updated with the above new sprites.
  • Nob Ogasawara names have been applied for the Pokemon applicable. Hereto, they'll be referred to as such.
  • The Cryithan line has been replaced with a new, more accurate evolutionary line, in Squeamata, Bawligua, and Iguanarch. It's mono Dragon and uses the original stats of pre-nerf Cryithan. Water moves have been revised.
  • Gavillain (Crocky) is now Dragon/Electric, having Blizzard and Ice Beam replaced with Thunder and Thunderbolt. Its Attack and Special are swapped. I also has a new spriteset featuring its more iconic "maned" design.
  • Omegadge (Omega) now has 106 ATK (+6) and Gawarhed (Gyaoon) now has 124 ATK (+14); this synchronises their BST.
  • Trampel now has 110 HP (-20), streamlining interactions a bit by making its Substitutes squishier.
  • Wiglett now correctly has 25 SPC (-10, accordance with the GSC SPC import rule)
  • Elekid now correctly has 95 Speed.
  • Galarian Slowking now has front and back sprites.
  • New back sprites for Crobat, Alolan Golem, Alolan Persian, Alolan Raticate, and Alolan Sandslash.
  • Sandy Shocks no longer gets Metal Sound.
  • Learnset tweaks have been made to sync with the ROM Hack. Generally, these do not affect the metagame. Overall, Tricules now has Smart Strike and Iron Defense, Cactormus gets Barrage, and Balumba + Sylveon now get Disarming Voice.
  • Luxwan and Sirfetch'd no longer get Hyper Beam, being consistent with SwSh.
  • Tyrogue now has a learnset.
  • Alolan Grimer now has a learnset.
  • Fixed a bug where Ponyta-Galar had a messed up Dazzling Gleam in its learnset.
  • (Hopefully) fixed a bug where Porygon-Z's sprite wouldn't show.
  • Moved Disturban and Carapthor to UU (from New), and Jolteon to UU (from OU)
  • Moved Mr. Mime to NU (oops!)
  • Moved Golbat, Poliwhirl, Primeape, Kadabra, Haunter, Tangela, Paras, Meowth, Ponyta, Growlithe, Doduo, and Grimer to NFE.
  • Moved Porygon, Onix, Ditto, Pinsir, and Farfetch'd to LC.
  • Being moved to a new server, many Gen 1 simulation bugs present in the old server should naturally be fixed.
Known issues:
  • Move descriptions are not entirely accurate; this is a client issue and unrelated to KEP's code itself.
A comprehensive list of Ogasawara name changes can be found here: https://github.com/scoopapa/DH2/pull/12

I'm also planning on hosting another tournament in the near future, but nothing is concrete yet. Stay tuned!
