Pokémon Uranium
A downloadable RPG Maker fan game, not a ROM hack: the all-original West Tandor region, 200 species, eight gyms and a randomized championship tournament instead of a fixed Elite Four.
More about the game
Pokémon Uranium is a fan game, not a ROM hack — a free, standalone game built in RPG Maker XP on Pokémon Essentials, released on August 6, 2016 after roughly nine years of development by JV and Involuntary-Twitch. It sets its own region, West Tandor, with 200 species split between 166 new creations and returning Pokémon, its own original Nuclear type, built around the region's nuclear-plant meltdown storyline, in-battle Mega Evolution, and Poké Radar hunting. Its release drew wide attention for a reason that had nothing to do with the game itself: one week later Nintendo issued a DMCA takedown of its download mirrors. The wiki this guide is built from records that the original team stopped active development shortly after, on September 21, 2016; the fan community has kept the game, its wiki and its online trading lobby running since, patching it past v1.3. This guide reflects whatever each wiki page's own most recent edit documents — individual pages cite fixes as late as v1.3.1 — rather than one single current-version snapshot, since the wiki itself never states one.
What's different, point by point
- An all-original region, West Tandor, with eight gyms and no fixed Elite Four
- 200 species: 166 of West Tandor's own plus a large selection of returning Pokémon
- A player-created type, Nuclear, tied to the region's own plot
- In-battle Mega Evolution
- Poké Radar hunting and tiered fishing rods
- An optional built-in Nuzlocke Mode
- A randomized 32-trainer Tandor Championship in place of a fixed Elite Four

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.
| Section | Source | |
|---|---|---|
| Wild Pokémon by area | From the game itself | Every route and location the wiki documents a wild table for, by method (grass, Poké Radar, each rod tier, surfing). |
| Encounter rates | From the game itself | The wiki's own per-species percentages. |
| Wild levels | From the game itself | The wiki's own level ranges per method. |
| Stats, abilities and movesets | From the game itself | Base stats, types, abilities and level-up movesets are the game's own — this is an original species roster, not a modified official one, so there is no base game to compare it against. |
| TM and HM compatibility | From the game itself | TM/HM compatibility per species, straight off each species' own moveset page. |
| Where TMs are found | From the game itself | Every TM and HM's field location, from the wiki's TM and HM list page. |
| Trainer and boss teams | From the game itself | Every trainer the wiki lists, on every route and in every gym. Gym leaders, the rival and the Tandor Championship's pool carry full rosters (ability, item, all four moves); ordinary trainers carry species and level only, because that's all the wiki — and the game itself — ever gives for them. |

Reading the tables
SourcesUranium has no released source code — it's a closed RPG Maker project — so everything here is read out of the Pokémon Uranium Wiki's own species, route and trainer pages rather than a decomp. The wiki's text is Fandom-hosted and licensed CC BY-SA; that licence is why it's credited above as a source, not only linked once.
TrainersOrdinary trainers on every route give species and level only — the wiki never publishes a moveset, held item or ability for them, because the game itself never shows one until you're already fighting. Gym leaders, the rival Theo (whose team depends on which starter you picked, at every rematch) and the Tandor Championship's own trainer pool are the only fights with full rosters, and those are given in full: ability, held item and all four moves per Pokémon.
ChampionshipThe Tandor Championship is a randomized 32-trainer single-elimination tournament, not a fixed Elite Four — the wiki's own page for it says the early rounds draw randomly from a pool that includes seven of the eight gym leaders (not Hinata or Kaito), two named trainers, and Hokage, and only the final match is fixed: always the rival, interrupted by a wild Actan and then the game's true final battle, CURIE's Urayne. Every roster below is real and hand-documented, marked '(random draw)' where the wiki itself says the matchup isn't guaranteed.
StagesThe stage picker is the eight badges in the order each gym's own wiki page states, plus the Championship. No per-area story order is published anywhere on the wiki beyond a route's own number and which routes border it, so no area is gated to a badge count here — every route shows under "Anywhere" rather than a guessed order.
Tm_LocationsTM and HM field locations are the wiki's own, straight off its TM and HM list page. They aren't tied to a badge count above for the same reason areas aren't.
Nuclear_Variants33 species also have a documented Nuclear-type variant — the irradiated form found around the region's nuclear plants — and each gets its own "Nuclear <Species>" entry here: same base stats, level-up moves and abilities as the standard form (the wiki never publishes different ones for it), with its typing changed to whatever the species' own page states.
Roster_ExceptionsOne trainer's one Pokémon in the whole guide has no species page: Elite Trainer Adam's Gengar (Lanthanite Core), whose entry on the wiki gives its held item, ability and moves for that fight but no dex number or base stats — it is not part of West Tandor's own 200-species Pokédex. Rather than publish stats for it from memory, it is left out of the Pokédex and shown only inside that one battle.
