Change GPS Location on iOS & Android in 1 Click.

Your Charmander reaches level 16, the battle ends, and the evolution animation starts before you've decided whether to evolve it into Charmeleon. You can stop the evolution by pressing B, prevent it with an Everstone, or train Charmander without evolving at the Route 5 Day Care.

Knowing how to stop a Pokémon from evolving in FireRed starts with understanding its evolution trigger. Level-ups, Evolution Stones, and trades require different approaches. You might want to keep a favorite form or delay evolution until your Pokémon learns an important move. If you also play Pokémon GO on an iPhone, Dr.Fone - Virtual Location can simulate a different GPS position on supported devices.

Part 1. Why Should You Stop Pokémon Evolution in FireRed?

Evolving a Pokémon changes its stats and the moves it can learn. However, keeping its current form a little longer can be useful, especially when waiting to learn a specific move or following a team strategy. To stop evolution in FireRed, it helps to understand why delaying evolution can benefit your Pokémon. Here are 5 main reasons players choose to wait:

• Learn Moves Before Evolving: Some Pokémon learn powerful moves earlier when they remain unevolved. Charmander learns Flamethrower at level 31, while Charmeleon learns it at level 34. Similarly, Bulbasaur learns SolarBeam at level 46, compared to level 56 for Ivysaur.
• Keep a Preferred Form: You can keep a Pokémon like Eevee in its current form for as long as you want. Simply avoid the conditions that trigger its evolution.
• Delay Evolution Until a Milestone: Wait until your Pokémon learns a specific move or reaches your training goal before allowing it to evolve.
• Follow a Challenge or Team Plan: Some players prefer unevolved-only challenges or specific team combinations. Preventing evolution helps them maintain their chosen Pokémon forms.
• Understand Evolution Triggers: Pokémon can evolve through leveling up, using an Evolution Stone, or trading. Friendship-based evolution also requires leveling up, so you can prevent it using the same methods.

Should You Evolve Pikachu Before Learning Thunderbolt in FireRed?

If you want Pikachu to learn Thunderbolt naturally, wait until level 26 before evolving it into Raichu. Unlike Pikachu, Raichu doesn't learn new moves through normal leveling in FireRed. Evolving Pikachu earlier means you'll need another way to teach Raichu Thunderbolt. However, there's no need to rush the evolution.

To learn how to stop Pikachu from evolving, simply avoid using a Thunderstone. Pikachu will remain unevolved regardless of its level. The table below compares the available methods for learning Thunderbolt, including their costs:

If you need a Thunderstone, Celadon City sells one at the Department Store for ₽2,100. Once Pikachu learns Thunderbolt, you can use the stone to evolve it into Raichu without losing the move.

Part 2. How to Cancel Pokémon Evolution in FireRed by Pressing B

Unlike Pikachu's Thunderstone evolution, a level-up evolution can be stopped immediately without using any item. FireRed gives you a short window to act while the Pokémon's sprite flashes between its two forms. To cancel evolution in Pokémon FireRed, simply press B during the animation. Here's how to do it:

1. Step 1 Raise Your Pokémon to Its Evolution Level

   Raise your Pokémon to its required evolution level by battling or using a Rare Candy.

   

2. Step 2 Press and Hold B During the Animation

   When "What? CATERPIE is evolving!" appears, press and hold "B" while the Pokémon's sprite flashes.

   

3. Step 3 Confirm the Evolution Has Stopped

   Keep holding "B" until "Huh? CATERPIE stopped evolving!" appears, confirming that your Pokémon remains unevolved.

   

Note: Canceling evolution only stops the current attempt. Your Pokémon will try evolving again at its next qualifying level-up. Give it an Everstone to prevent repeated evolution attempts.

Why Does Pressing B Not Stop Every Evolution in FireRed?

Pressing B only cancels level-up evolutions in FireRed. It cannot stop evolution triggered by an Evolution Stone or a trade. Once you use the correct stone, evolution proceeds, while trade evolutions occur in the receiving game.

To stop evolution in Fire Red, the best method depends on the Pokémon. Pikachu and Eevee remain unevolved unless you use the appropriate Evolution Stone. Similarly, trade evolvers like Kadabra and Haunter stay unchanged until traded. If you want to prevent evolution during regular training or trading, an Everstone offers another option.

Part 3. How to Stop Pokémon Evolution with Everstone in FireRed

An Everstone prevents evolution while a Pokémon holds it, so you don't need to press B after every level-up. Under FireRed's Generation III rules, an Everstone blocks level-up and trade evolutions, but not stone evolutions. For example, using a Thunderstone on Pikachu while it holds an Everstone will still trigger evolution and consume the stone.

Professor Oak's aide gives you an Everstone at the Route 10 Pokémon Center after you've caught 20 different Pokémon species. To stop evolution in FireRed with an Everstone, you need to know where to find it and how to give it to your Pokémon. You can also remove it whenever you're ready to allow evolution. The following methods explain each process:

FireRed Everstone Location: Where to Find It on Route 10

The FireRed Everstone location is the Route 10 Pokémon Center, near the northern entrance to Rock Tunnel. Professor Oak's aide checks your Pokédex before handing it over. Only caught species count, including evolved, traded, and gift Pokémon. Follow these steps to collect the Everstone:

Instructions. Head east from Cerulean City along Route 9, using Cut to reach the route, then continue toward Route 10. Enter the Pokémon Center near Rock Tunnel's northern entrance and speak with Professor Oak's aide. If you've caught at least 20 different Pokémon species, he'll give you the Everstone, which goes into your Bag's Items pocket. Otherwise, he'll tell you how many species you've caught so far.

How to Give a Pokémon an Everstone in FireRed

An Everstone prevents level-up evolution without affecting experience gain or move learning. It works as long as the Pokémon holds it. To stop evolution in FireRed without pressing B after every level-up, follow these steps to give your Pokémon an Everstone:

Instructions. Press "Start" and open "BAG," then navigate to the "ITEMS" pocket. Select the Everstone and choose "GIVE" to open the "Give to which POKéMON?" prompt. Pick your Pokémon, and the game confirms it "was given the EVERSTONE to hold." If the Pokémon already holds another item, FireRed asks whether you want to switch them.

How to Remove Everstone and Evolve Pokémon Later

Removing the Everstone doesn't trigger evolution immediately, as FireRed checks for evolution only when the required conditions are met again. When you're ready to evolve a Pokémon in FireRed, follow these steps to remove its Everstone:

Step 1. Press Start, choose "POKéMON," and select the Pokémon holding the Everstone.

Step 2. Choose "ITEM," then "TAKE," and the game confirms the Everstone is back in your Bag.

Once you've removed Everstone, you can evolve your Pokémon using the method that matches its evolution requirements:

• Level-Up Evolvers: Raise your Pokémon another level through battle or a Rare Candy once it meets the required evolution conditions.
• Stone Evolvers: Use the appropriate Evolution Stone from your Bag to trigger evolution, regardless of whether the Pokémon holds an Everstone.
• Trade Evolvers: Trade your Pokémon without its Everstone to trigger evolution in the receiving game. The other player can then trade it back.

Part 4. How to Level Up Pokémon Without Evolving in FireRed

Unlike pressing B or using an Everstone, the Day Care lets you train Pokémon without triggering evolution. Located on Route 5, south of Cerulean City, it accommodates one Pokémon at a time and grants one experience point for every step you take. To stop evolution in FireRed while gaining levels, leave your Pokémon at the Day Care and follow these steps:

Instructions. Visit the Day-Care Man on Route 5 and leave the Pokémon you want to train. Make sure you have at least one other usable Pokémon in your party. Continue exploring, as your Pokémon gains experience with every step you take. When you return, the Day-Care Man tells you how many levels it gained. Pay ₽100 plus ₽100 for each level gained to collect your Pokémon.

Note: Collecting a Pokémon from Day Care doesn't trigger evolution. However, it can evolve during its next qualifying level-up through battle or a Rare Candy. You can press B during the evolution animation to stop it.

Can Pokémon Learn Moves While Staying in Day Care?

Pokémon can learn new moves while staying at Day Care, but you cannot choose which moves they forget. When all four move slots are full, learning a new move automatically replaces the first-slot move, shifting the remaining moves up.

This can overwrite a valuable move taught through a single-use TM, such as TM24 Thunderbolt. To avoid losing important moves, place less valuable ones in the first slot before leaving your Pokémon. Alternatively, train it yourself and use B or an Everstone to prevent evolution while maintaining control over its moveset.

Part 5. Pokémon FireRed Evolution Guide: How to Stop Different Evolutions

Not every Pokémon evolves through the same method. Bulbasaur, Charmander, and Squirtle evolve by leveling up, while Pikachu and Growlithe require Evolution Stones. Others, such as Kadabra and Haunter, evolve through trading. To cancel evolution in Pokémon FireRed, you first need to understand what triggers it. The table below explains each Pokémon's evolution requirements and how to keep it unevolved:

Pressing B only works during level-up evolution. For stone evolutions, avoid using the required Evolution Stone. To prevent trade evolutions, avoid trading or have the Pokémon hold an Everstone.

Note: Before obtaining the National Pokédex, FireRed prevents Pokémon from evolving into species outside the original Kanto Pokédex. For example, Golbat's evolution into Crobat starts but stops with a "……?" message.
