Basically what I actually want to know is, if I rename a Pokémon to its original name and trade it, will the traded Pokémon evolve with its proper evolved Pokémon name or retain its "nickname"?

For example, I catch an Ekans and nickname it "Slithers". Later on I decide to trade it and want to remove my nickname in case people on GTS don't like it. I nickname it back to its original form's name with the exact spelling and capitalization, "Ekans".

When the other person receives my Pokémon and evolves it, will it become "Arbok" or remain as "Ekans"?

  • Not 100% certain, but as far as I know it'll count as a nickname and not change on evolution.

    Not a duplicate: this is about 6th gen, the other question is about 5th, and the answer is the opposite!

The Pokemon will retain the changed nickname.

So if you have got a Pikachu you called "Pika" earlier, you may visit the house of the name rater and change it it to "Pikachu", but if it evolves it's still called "Pikachu" and not Raichu. (In Camphrier Town right after Lumiose City you will find the Name Rater in the Pokemon Center.)

Furthermore, if you trade it and your friend evolves it to Raichu it's still called "Pikachu" and he will NOT be able to change the name of it (due something like "it's the earlier trainers spirit")

So, no you can't delete a pokemons nickname. But you may change it to "Raichu" for example, trade it - and if your friend evolves it later on, the name is matching.

Except for using a cheat module, this is the only way to deal with stupid nicknames.

However, there is the chance of using a bug in generation 6: If the name contains special characters (like the Asian ones), the game will remove the nickname if you swap your Pokemon with somebody else. This way would cost you about 20 bucks to buy the Asian version, which is quite expensive (for a nickname) but the only way if you don't want to be reported for an inapropriate name.

Since I could not find any evidences on the internet, I may just rely on the two user comments below.

It may be possible to change a Pokemon's nickname in the Generation V and VI as Bulbapedia noticed the following:

Starting in Pokémon Black and White, whenever a player catches a Pokémon and decides to nickname it right afterwards, he or she may tap the Pokémon's sprite or model on the nickname screen to reset the nickname back to the Pokémon's species name.

This means, one tap and your nickname will be set to the species name. By accepting this nickname the game would check, whether it matches the species name or not and would remove the nickname-bit. This would explain, why user2357112 was able to restore it's species name.

I do not own these generations by myself, so if anybody could check this, I'd love to credit him here.

    Give all Pokemon nicknames of "Dragonite".

    I just nicknamed a Pansear "Test", nicknamed it back to "Pansear", and evolved it, and the name became "Simisear". Are you sure things still work the way you describe? Commented Jan 2, 2015 at 1:09
  • No, this should not have worked. There is a nickname-bit stored with every Pokemeon to determine wether it's been nicknamed or not. Even if you re-nick it back to its usual name, it still has this bit set. To be honest, I do not own the 5th generation. I'm pretty sure I had a validlooking source of information in april and wish I had mentioned it above... my fault. I'm going to update the answer. Thank you sir. Commented Jan 2, 2015 at 4:43

No. Since Diamond/Pearl there is "Nicknamed" bit stored in individual values bytes, probably to allow dynamically changing the nickname when Pokémon was traded internationally using GTS. The name rater always sets this flag, even if you changed the name to species name.

However, this only applies to Diamond/Pearl, and games released after it. Before GTS that allowed online trades (well, technically Pokémon Communication Center also allowed trading, but it was Japan-only, so no issue here), there wasn't a nickname flag. The game determined if the specie was nicknamed in very simple way - if it had the same name as the specie in your name, it was assumed to be not nicknamed.

This obviously caused a problem when the Pokémon was traded internationally and evolved, but before fourth generation such trades were rare (before you ask, yes, Game Boy games allowed international trades, but only between versions using Latin alphabet).

Just for fun, the only Pokémon that couldn't be restored to original nickname in second generation was Porygon2, because you couldn't type "2" normally.

In fifth generation (not sure about sixth), there is the only way of removing nicknames I'm aware of, but it's probably not intended to be used in this way. There is a filter in a game (client-side, server instantly rejects such names, which is an issue with specie names like Nosepass) that automatically removes a nickname when you try to send to the GTS something with a censored nickname (warning: link contains potentially offensive words). You may want to use something censored, and the game will automatically change it into species name when sending it using GTS.


As soon as you rename your Pokemon for the first time, it will never return to being without a nickname. Even if you rename it to the original name, it will still be considered nicknamed and won't change on evolution.


Sorry for answering an old question but it seems important to clear some things up.

In generations 5-3 if you nickname a pokemon and re-nickname it into its generic name, the nickname byte will not be changed. In other words, the pokemon will still be nicknamed.

However, in generation 6 if you do the same the nickname byte will be reset and the pokemon will not have a nickname.

You may test this in your own game. For example if you nickname a NFE pokemon and re-nickname it back to its original name and evolve it, its name will change into the species name of its evolved form. Another example is specifically in ORAS - activating the encounter with Regigigas in Island cave will require a Regice with a nickname bit in the party among other things. If you nickname Regice its species name, this event will not work. Testable evidence aside, I have analysed pkx files of nicknamed pokemon and pokemon re-nicknamed and can attest that these pokemon do not have the characteristic "nickname byte".

Other things to note- If a pokemon from a previous has the nickname byte and is nicknamed its generic name and is transferred to gen 6 via poke-bank, it will retain its nickname byte. If a pokemon originally from gen 3-4 (where names are by default capitalized)and does not have the nickname byte and is transferred to gen 6, then its name will de-capitalize as standard per generations 5-6.

  • Regarding earlier Gens, this answer seems to say otherwise. For Gen 6, I have not tested it out myselft, but there seems to be other people who are inline with what you are saying.

When you make a nickname, it is a nickname throughout their journey and yours. So if you decide to give them on, they will be called that forever, unless you change it. It will never change by itself. For example, naming Squirtle 'Squirtle' will cause them to be called 'Squirtle' for the rest of time, even if they evolve to Wartortle and Blastoise. If you don't want them to have a nickname, and just evolve with their pokemon name, just say no. You can't delete a nickname, so don't give 'em one if you don't want one!


In Black and White, you can go to the name rater, tap the sprite next to the name of your pokemon and it will change it to it's original species name, then when you evolve it, the name will change acording to the pokemon's new species. I have just tried it and it does work.


I'm have just experimented with this and using the name rater to change the name back to the species name works to remove a nickname. Eg nickname a Magikarp something like ABC, re-nickname it back to Magikarp, and then evolve it. The name changes to Gyarados. Were it to be considered a nickname it wouldn't change.
