In-game trade

This article is incomplete. Please feel free to edit this article to add missing information and complete it. Reason: Check that the Gen II held items of trade evolutions and Japanese Blue's Krabby are correct

All Trainer ID numbers and IVs are random in the Generation I games. The Original Trainer always uses the hardcoded text string 0x5D, which is displayed as "TRAINER" (Japanese: トレーナー Trainer) in the game's language. In Western language versions of the handheld games and Pokémon Stadium, this string is displayed in ALLCAPS ("TRAINER" in English), whereas in Pokémon Stadium 2 it is displayed in title case ("Trainer" in English). When transferred using Poké Transporter, this string is permanently converted to title case in the language of the game it was transferred from, being changed to use a literal string instead of a language-sensitive control character.

The held item column refers to the item the Pokémon will be holding if it is traded to a Generation II game. With the exception of Pokémon that evolve during that trade and Krabby in Japanese Blue, they have the same item a wild Pokémon of the same species would have if it were traded to a Generation II game; Pokémon that evolve during the trade have the item their evolved form would have, while Krabby has TM13 (Snore) instead of TM33 (Ice Punch).

In Pokémon Red and Blue, Nidoran♂ is traded for Nidoran♀; in Pokémon Red and Green, Nidoran♀ is traded for Nidoran♂.

This (full) data is stored in Mobile System GB related code for Japanese Pokémon Crystal. It also appears earlier in the ROM, but with the Original Trainer data not included. Kabīn is possibly a reference to the Game Freak Kōji Nishino and Snorlax (Japanese: カビゴン) in-jokes, and the early 'Kabīn battle' concept art. The code remains in English Crystal, however, the Japanese names were not translated; resulting in garbage text, and the game causes problems as it expects the English name length.

In the English language version of Pokémon Diamond and Pearl, Kazza, Charap, and Gaspar are functionally Japanese in origin. While this has no effect in the Generation IV games (since their species do not have foreign Pokédex entries in the Generation IV games), it becomes noticeable when sent to later generations. These Pokémon have the correct language of origin if obtained in any other game language or Pokémon Platinum.

Main article: Hayley's trades

Unique to this generation, some of the Pokémon that are traded to the NPC can be battled again by that NPC. These are marked with a † icon. The gender and Ability traded is kept in the new battle, and in Black and White, the traded Pokémon evolves, but the moves may change, even if HMs were taught to the Pokémon when traded. The new level is based on the level of the Pokémon traded to the NPC: 65 if it was below 65, 5 more than the initial level if it was at least 65 but below 96, and 100 if it was at least level 96.

Except for trades with Yancy and Curtis, all traded Pokémon are guaranteed to have 1 perfect IV and all others set to 20.

In Nimbasa City, after returning the Dropped Item to the owner and calling them 15 times, Yancy or Curtis (depending on the player's gender), will trade the player a different Pokémon each day, in this order. Each Pokémon has its Hidden Ability and can be either male or female.

If the player is male

Yancy's Pokémon have the Original Trainer Yancy (Japanese: ルリ Ruri) and Trainer ID number 10303.
