No, Pokémon that evolve through trading do not evolve when they are transferred. In order for these Pokémon to evolve, they must be traded between two players. Once the trade is completed, the Pokémon will evolve as a result of the trade. However, if a Pokémon that evolves through trading is transferred to another game or player, it will not evolve as a result of the transfer. **

One way to evolve Pokémon through trading without losing friendship is to trade with a friend or another player who you trust to trade the Pokémon back to you after it evolves. This way, you can still benefit from the evolution without losing the bond you have built with your Pokémon. Another option is to trade with someone who is willing to trade back the evolved form of the Pokémon to you. This way, you can complete the evolution process without sacrificing the friendship level of your Pokémon. **

In the original Pokémon games, Kadabra can be evolved into Alakazam without trading by using a specific method. One way to evolve Kadabra is to use a special item called the "Link Cable" in the game. By using the Link Cable, Kadabra can be traded with another player's game, and then immediately traded back. This will trigger the evolution of Kadabra into Alakazam without the need for a traditional trade. **

One way to keep Pokémon that can only evolve through trading is to find a friend or family member who also plays the game and trade with them. Alternatively, you can use online forums or social media groups to connect with other players who are willing to trade with you. Another option is to use the Global Trade System (GTS) feature in the game to trade with random players from around the world. Finally, some games have introduced items like the "Link Cable" or "Evolutionary Stone" that can be used as a substitute for trading to evolve certain Pokémon. **

To evolve Pokémon through trading without losing their friendship, you can trade them with a trusted friend or another one of your own game consoles. This way, the Pokémon will still recognize you as their original trainer and maintain their friendship level. Additionally, you can use items like the Everstone to prevent evolution if you want to keep the Pokémon in its current form while trading. Finally, make sure to communicate with the person you are trading with to ensure they understand your preferences for evolving the Pokémon. **

In Pokémon Red/Blue, some Pokémon can evolve without trading by leveling them up to a certain level. For example, Charmander evolves into Charmeleon at level 16 and then into Charizard at level 36. Another way to evolve Pokémon without trading is by using evolution stones, such as the Fire Stone to evolve Eevee into Flareon or the Thunder Stone to evolve Pikachu into Raichu. Additionally, some Pokémon evolve when they are exposed to a specific location or condition, such as leveling up near a Moss Rock to evolve Eevee into Leafeon. **

Metapod doesn't evolve because it is already in its final evolutionary stage. Metapod evolves from Caterpie at level 7 and then evolves into Butterfree at level 10. Once Metapod reaches level 10, it automatically evolves into Butterfree, so there is no further evolution for Metapod. Its role in the evolutionary line is to act as a transitional stage between Caterpie and Butterfree. **

Kakuna doesn't evolve because it is already in its final evolutionary stage. Kakuna evolves from Weedle at level 7 and then evolves into Beedrill at level 10. Once it reaches the Kakuna stage, it remains in that form until it reaches level 10. At that point, it will automatically evolve into Beedrill. **
