What makes it different

Hoenn rebuilt on Ruby with a regional dex of its own: 411 entries in a new order, 40 Mega forms, the Fairy type and the physical/special split.

More about the game

Omega Ruby Origins is a Ruby ROM hack that keeps Hoenn's map and its eight Gym Leaders and changes almost everything inside them. Its Pokédex is its own: 411 entries running from Bulbasaur to Giratina in an order that belongs to this game and nobody else, mixing species from every generation, with 40 Mega forms numbered among them as ordinary entries. The Fairy type is in, attacks are physical or special by the move rather than by the type, and the wild tables across 96 areas are stocked from that whole list rather than from Hoenn's. The difficulty is the reason people play it: the eight leaders finish at level 76, the Champion's team is level 100, and most of the map's wild Pokémon top out in the thirties. This guide is a partial one. It carries everything the creator published — every species with its stats, abilities and level-up list, the whole move table, the wild tables with their level ranges, and all thirteen boss teams down to the held items — and it says so plainly where the documentation stops: no TM numbers or locations, no ordinary trainers, and no rates on the wild tables.

What's different, point by point

  • 411 dex entries in this game's own order, drawn from every generation, with 40 Mega forms sitting in that numbering as entries of their own
  • Mega Evolution through one item: 26 species evolve into their Mega with the Evo. Gem, and Charizard has a second one through the Evo. Gem X
  • The Fairy type is in — 26 of the 411 entries carry it
  • The physical/special split: every move carries its own category, so Crunch is physical and Dark Pulse is special
  • Hoenn's eight leaders in the usual order, finishing at level 76, then an Elite Four from level 84 and a Champion whose team is level 100
  • Boss teams are built like competitive ones: held items, abilities and four chosen moves on every Pokémon
  • The creator's own listing also names a Kaizo difficulty option and double battles

What this guide covers

Every guide here is built from the game's own documentation. Where a ROM hack changed something but never published the numbers, this says so rather than quietly filling the gap with the original game's — which would be worse than leaving it out.

SectionSource
Wild Pokémon by areaFrom the game itselfEvery wild table the creator published: 96 areas, by method, with the species in each.
Encounter ratesNot published by the creatorThere is no rate in the creator's data at all. The engine's slot table is in there, but the per-area lists have been folded down so that a species can no longer be matched to a slot, and the percentages the creator's site displays are made up by that site from the method — the same number on every grass table in the game. Neither is a rate, so none is shown. The creator's documentation site Omega Ruby Origins is built on Ruby / Sapphire; the Ruby / Sapphire guide has the original game's encounter rates.
Wild levelsFrom the game itselfLevel ranges are published per species per table, and are shown as given.
Stats, abilities and movesetsFrom the game itselfAll 411 dex entries, with base stats, typing, abilities, level-up lists, TM and HM compatibility and evolutions, as the creator published them.
TM and HM compatibilityNot published by the creatorWhich moves a species can be taught by machine is published and is on every species page. The numbers themselves — which move is TM01 — are not published anywhere, so there is no TM table to show. The creator's documentation site Omega Ruby Origins is built on Ruby / Sapphire; the Ruby / Sapphire guide has the original game's TM and HM compatibility.
Where TMs are foundNot published by the creatorNo machine, item or tutor in this game has a published location. The creator's documentation site Omega Ruby Origins is built on Ruby / Sapphire; the Ruby / Sapphire guide has the original game's TM locations.
Trainer and boss teamsFrom the game itselfThe eight Gym Leaders, the Elite Four and the Champion, in full. Ordinary trainers are not published anywhere in the creator's documentation, so this guide has none of them.

Reading the tables

RatesThe wild tables give species and level ranges and nothing else. The game's own slot chances are not in the creator's data, and the percentages shown on the creator's site are produced by that site from the method alone — every grass table there reads 45% — so they are not this game's numbers and are not repeated here.

StoryThe creator's documentation publishes no story order: no gym cities, no field-move locations, no level caps. The checkpoints here are the eight leaders in the order the creator lists them, and each area is filed where it sits on Hoenn's own map, because this game keeps Hoenn's routes and Hoenn's eight leaders in sequence. Where this game's wild levels sit well away from that point — the level 18 to 25 Petalburg Woods is the clearest — the area's note says so. Treat the checkpoints as a reading order, not as a route the game confirms.

MethodsSurf, Rock Smash and the three rods are listed with no badge against them, because nothing in the creator's documentation says when this game hands them out. An area's own checkpoint is the only claim this guide makes about when you can get there.

MachinesEvery species page lists the TMs and HMs it can be taught, by move name. The game's TM numbers are not published anywhere in the creator's documentation, and neither is where any machine is found, so there is no TM table and no TM locations.

BossesThe thirteen teams here are the eight Gym Leaders, the four Elite Four members and the Champion, with the held item, ability and four moves the creator gave each Pokémon. Roxanne fields five; the other twelve field six. No ordinary trainer is published anywhere in the documentation, so none is listed. The creator marks one Pokémon on each team as its ace — this guide has no place to show that yet, so it is left out rather than guessed at.

SpeciesSpecies names come from the game's own name table, which allows ten characters, so the longer ones arrive cut short and every alternate form arrives abbreviated. They are written out in full here, and each form was matched to its full name by its own typing and stats rather than by its abbreviation. 35 Pokémon that boss teams field have no dex entry in the documentation, so they appear on the fight pages with no page of their own.

VersionThe creator's listing gives the version as 1.4.8.7 and dates its gallery to April and May 2026; no exact release date is published, so the date in the facts box is the first of May 2026 and should be read as that month, not that day.

OwnershipThis guide is built from a documentation site that the creator's own catalogue listing links as theirs, published by a GitHub account whose name matches the credited studio. Nothing inside that site names playerbrendan, and the site itself is a generic template with placeholder art around the real data; the box art on the catalogue page is signed Player Brendan. The data is this game's own — its dex order, its Mega forms and its move categories are nothing a template would invent — but the link between the site and the creator rests on the catalogue listing and the studio name, and that is worth knowing.
