Things you'll need to go from Generation 3 --> 6 (aside from games)
- Nintendo DS, or Nintendo DS Lite (contains both a GameBoy Advance game pak slot, and a Nintendo DS game card slot)
- A Second Nintendo DS to transfer Pokemon from generation 4 --> 5
- A Nintendo 3DS to transfer Pokemon from generation 5 --> 6. If you have a 3DS, you don't need the DS from the last step.
Generation 3 --> 4
Transfer up Pokemon using PalPark from Ruby, Sapphire, FireRed, LeafGreen, and/or Emerald to Diamond, Pearl, and/or Platinum. For this you need an original Nintendo DS or a Nintendo DS Lite as you need access to a Nintendo DS game card slot, and a GameBoy Advance game pak slot. Additionally, you can not transfer up eggs.
Gamecube Games --> Gen 3
You can also transfer up Pokemon from Pokemon Colosseum or Pokemon XD: Gale of Darkness to a modern Pokemon game, you just need to transfer them via trade to a generation 3 game, and then transfer them up like normal Pokemon.
Generation 4 --> 5
At Route 15 in Black or White you'll have to transfer everything up from your generation 4 games. For this, you'll need 2 Nintendo DS systems, one following the instructions in Pokemon Black, White, Black 2, and White 2, and another with the generation 4 game inserted running DS Download Play. You can transfer up Pokemon in this fashion, however there are a few stipulations:
- Held items will not be transferred up to generation 5 (they'll automatically be returned to the player's bag)
- The Pokemon being transferred can not know any HM moves.
- You can not transfer eggs.
- The Spikey-eared Pichu (a promotional exclusive) can not be transferred up.
Generation 5 --> 6
Starting December 27th 2013, download the 3DS application titled Pokemon Bank from the Nintendo eShop. This application can take Pokemon from a Generation 5 or 6 Game, and store them inside of the app. After this process is done, withdraw the Pokemon from Pokemon Bank in your generation 6 game.
Things to note when transferring Pokemon
- All Pokemon are forever lost from their past generation game - there is no way to transfer a Pokemon back to its previous generation.
- Game mechanics change between generations. While a team might be effective in one game, it might not prove to be useful in another. Notably moves are assigned
physical
or special
in generation 4 onwards; and generation 6 introduces new mechanics such as the fairy type, base stat changes, and move changes.
No. Effects that boost exp gain will not boost the entire parties exp gain when the pokemon in question participated in battle. You will see the active pokemon get boosted exp and then the rest of your pokemon get half of "normal" exp.
- For example if you had a pokemon with a lucky egg up front and he got
150 exp then the rest of your pokemon would get 50 (half of 100, the
original exp gain).
However, as Haidro points out, if the pokemon that would get boosted exp does not participate in battle they will still get boosted exp of the half they receive from the exp share.
- So if you had a pokemon up front with no boosted exp and they got 100. Most of your pokemon would get 50 but the one with the exp boost would get 75 (50 boosted).
Note these numbers assume 50% exp boost, I'm not positive that is correct but its easy to do math with and I feel it still shows the point.
Best Answer
This is only possible in Pokémon Yellow (Pikachu only), and Heart Gold/Soul Silver (The first Pokémon in your party), where your Pokémon follow you automatically.
There's also a special park on Platinum and a side-quest on Black/White 2, but these don't count as "walking Pokémon".
Also in the side games Pokémon Ranger and Pokémon Mystery Dungeon games, Pokémon can be outside with you in most places.
Edit: Pokémon are also allowed to be out on games such as Let's Go Pikachu and Eevee, or Sword and Shield on the DLC content's Islands.
