Tradingplays a vital role in thePokemonfranchise. Trainers will exchange Pokemon to complete the Pokedex, for Shiny Hunting, or for various other reasons.

While trade-evolution Pokemon could be evolved without needing to trade inPokemon Legends: Arceus, this doesn’t seem to be the case withPokemon Scarlet&Pokemon Violet, much to somePokemonfans' disappointment. Fortunately for some, there are only 3 out of 400 Pokemon inScarlet/Violetthat have a trade evolution.
Pokemon That Evolve Through Trade In Paldea
There is not one Generation 9 Pokemon inScarlet/Violetthat needs to be traded to evolve. However, that hasn’t stopped some Kanto Pokemon from wandering about Paldea, and since they’re inScarlet/Violet, they’re necessary to complete the Pokedex. The Pokemon that evolve by trade are the following:
Must be holding a Metal Coat

Must be holding a King’s Rock
N/A
Slowpoke and Scyther’s “trade evolution item” is the King’s Rock and Metal Coat respectively. Unlike previous mainline games where evolution items were locked behind Battle Points (BP),Scarlet/Violetallows players to purchase them for 3,000 poke dollars atDelibird Presents. Make sure that Slowpoke and Scyther are holding the required items before sending them off in a trade.
What If You Don’t Have Anyone To Trade With?
Pokemon Scarlet & Violetplayers that are struggling to find someone to trade their Slowpoke, Haunter, or Scyther with are in some luck. The evolutions of these three Pokemon (Slowking, Gengar, and Scizor)can be obtained in5-6 Star Tera Raids. These are Tera Raids that can be difficult to complete without a Group, but they’re not impossible to win. It’s highly recommended that trainers bring their best Pokemon with solid builds/stats and movesets. Using a Pokemon with a Type advantage over the Tera Raid Pokemon also helps.
Players can check for Slowking, Gengar, or Scizor by interacting with any of the Tera Dens around Paldea.However, 5-star raidscan’t be attempted until the post-game. Additionally,6-star raids are locked behind the Champions/post-game tournament. This means that if players are in a rush to get Slowking/Gengar/Scizor, they’re better off evolving their Pokemon via trade.
