Pokemon Gaia Evolution Changes: New Levels, Items, and Places
In the original Pokémon games, some Pokémon require trading, special items, or specific locations to evolve, which can be challenging to replicate in a ROM hack. Pokémon Gaia addresses this by providing new ways to evolve nearly every tricky Pokémon on your own.
This article explains how evolution works differently in Gaia, details how to evolve Pokémon that usually need trading, shows you how to get all the Eeveelutions, and includes a handy reference table that you can use as a checklist.
How Evolution Is Different in Pokémon Gaia
In Pokémon Gaia, many Pokémon now evolve differently compared to before. Instead of needing to trade Pokémon or use special items with a friend, you can evolve them while playing alone.
Most Pokémon that used to evolve by trading will now evolve at a certain level, with an evolution stone, or with a special item. Some Pokémon will evolve in specific locations, like near an Icy Rock or in a building with a generator. A few Pokémon still need friendship to evolve.
Trade Evolutions in Gaia (No Trading Needed)
In official Pokémon games, some Pokémon, like Haunter and Machoke, only evolve when you trade them with another player. This can be difficult or impossible for people playing a ROM hack by themselves.
In Pokémon Gaia, these trade evolutions have new methods. This means you never need to trade to complete your team.
Classic trade Pokémon
Some Pokémon normally evolve through trading, but in Gaia, they evolve by leveling up instead. Here are the details:
- Kadabra → Alakazam at level 40
- Machoke → Machamp at level 42
- Graveler → Golem at level 36
- Haunter → Gengar at level 40
- Boldore → Gigalith at level 42
You can keep these Pokémon in your party, train them, and they will automatically evolve once they reach the correct level.
Trade + item Pokémon
Some Pokémon in the official games need to be traded and have a held item to evolve. In Gaia, you can use the item or a special stone instead.
Here are the details:
- Onix → Steelix at level 40
- Clamperl → Huntail at level 38
- Clamperl → Gorebyss with a Regal Stone
- Seadra → Kingdra with a Regal Stone
- Poliwhirl → Politoed with a Regal Stone
- Slowpoke → Slowking with a Regal Stone
- Scyther → Scizor with a Regal Stone
- Feebas → Milotic with a Regal Stone
- Porygon → Porygon2 using an Up‑Grade like a stone
- Porygon2 → Porygon‑Z using a Dubious Disc like a stone
- Rhydon → Rhyperior at level 55
- Gurdurr → Conkeldurr at level 42
Instead of trading while they hold the item, just use the stone or item on them, or level them up to evolve.

|---|---|---|
| Kadabra | Level 40 | Alakazam |
| Machoke | Level 42 | Machamp |

| Slowpoke | Regal Stone | Slowking |
| Scyther | Regal Stone | Scizor |
| Feebas | Regal Stone | Milotic |

| Porygon2 | Dubious Disc (used as stone) | Porygon‑Z |
| Rhydon | Level 55 | Rhyperior |
| Gurdurr | Level 42 | Conkeldurr |
Tips for trade‑style evolutions
Before you evolve a trade Pokémon, check what moves it can learn later. Sometimes it’s better to wait a level or two so that it can learn a strong move before evolving. If you evolve too early, you can still use move tutors or TMs later to improve your moveset.
Eevee Evolution Changes in Pokémon Gaia
Why Eevee is special
Eevee is unique because it can evolve into many different forms. In Pokémon Gaia, there are clear and simple ways to get each evolution. Some require special stones, others need specific locations, and one has two different methods.
Stone‑based Eeveelutions
In Gaia, these Eeveelutions use stones:
- Eevee → Espeon with a Sun Stone
- Eevee → Umbreon with a Moon Stone
- Eevee → Sylveon with a Shiny Stone
- Eevee → Sylveon by leveling up while it knows a Fairy‑type move
- Eevee → Jolteon, Flareon, Vaporeon still use Thunder, Fire, and Water Stones like usual
Location‑based Eeveelutions
Eevee evolves into two different forms depending on where you level it up:
- To get Glaceon, level up Eevee near the Icy Rock on the first floor of Frostbite Cave.
- To get Leafeon, level it up inside Nemesis Cave.
To evolve into Glaceon, enter Frostbite Cave, find the Icy Rock on the first floor, keep Eevee in your team, and battle until it levels up nearby. For Leafeon, just go into Nemesis Cave, keep Eevee in your party, and level it up inside the cave.
Eevee evolution table
| Eeveelution | Method in Gaia | Item / Location |
|---|---|---|
| Espeon | Use Sun Stone | Anywhere |
| Umbreon | Use Moon Stone | Anywhere |
| Sylveon | Use Shiny Stone | Anywhere |
| Sylveon | Level up with a Fairy‑type move | Anywhere |
| Glaceon | Level up near Icy Rock | Frostbite Cave (1F) |
| Leafeon | Level up in cave | Nemesis Cave |
| Jolteon | Use Thunder Stone | Anywhere |
| Flareon | Use Fire Stone | Anywhere |
| Vaporeon | Use Water Stone | Anywhere |
Other Location‑Based Evolutions
What location‑based evolution means
A location-based evolution means a Pokémon levels up in a specific place instead of using an item. Gaia includes a few of these to match newer mechanics.
Magnetic field evolutions
Two Pokémon in Gaia evolve when they level up in a building with a strong generator:
- Magneton evolves into Magnezone when leveled up in Telmurk Warehouse with the generator.
- Nosepass evolves into Probopass when leveled up in Telmurk Warehouse with the generator.
To do this, go to Telmurk, find the warehouse with the generator, keep Magneton or Nosepass in your party, and level it up there.
Other special places
Leafeon and Glaceon also evolve in specific locations. If you find more special places later in the game, use the same method: bring the right Pokémon, stay in that area, and level it up inside.
Stone and Item Evolution Tweaks
Regal Stone evolutions
The Regal Stone changes how some Pokémon evolve through trading. Instead of trading a Pokémon while holding an item, you now use the Regal Stone to evolve them. Here’s how it works:
- Clamperl → Gorebyss with Regal Stone
- Seadra → Kingdra with Regal Stone
- Poliwhirl → Politoed with Regal Stone
- Slowpoke → Slowking with Regal Stone
- Scyther → Scizor with Regal Stone
- Feebas → Milotic with Regal Stone
This change makes it easier to get strong Water, Psychic, and Bug/Steel Pokémon.
Other important item and stone changes
Some Pokémon evolutions that used to require trading with special items now only need the item, like a stone, or a simpler level. Here are the changes:
- Electabuzz → Electivire with a Thunder Stone
- Magmar → Magmortar with a Fire Stone
- Sneasel → Weavile at level 35
- Dusclops → Dusknoir with a Dusk Stone
These changes keep the original spirit of the games but remove the need for another player.
Where to find stones
You can find evolution stones in the Orbtus region in several places, including shops, hidden spots, caves, and as rewards from NPCs. Since there are many locations, it’s a good idea to keep a separate notes page or guide to track where you find each stone while you explore.
Regular Level‑Up Changes
Some Pokémon that evolve by level in the official games have different levels in Gaia, or they keep the same level but are included here to avoid confusion.

Friendship, Special Conditions, and Tips
Friendship evolutions in Gaia
Friendship (or happiness) is important in Gaia, and at least one Pokémon in your team uses it:
- Budew → Roselia by leveling up with high friendship
There might be other friendship evolutions in the game, but Budew is a clear example. To evolve Budew, raise its friendship and level it up during the day.
How to raise friendship with your Pokémon
To raise friendship with your Pokémon in gaia, follow these steps:
- Keep the Pokémon in your active party.
- Walk and battle with it often.
- Do not let it faint too much.
- Use vitamins, berries, and useful items on it.
If you can, visit the NPC in Gaia who checks friendship to see how happy your Pokémon has become.
