Trade evolution is weird. It’s always been weird. Back in 1996, Satoshi Tajiri and the team at Game Freak wanted to force kids to talk to each other, so they locked some of the coolest monsters behind a Link Cable. If you didn't have a friend with a Game Boy, you weren't getting an Alakazam. Period. Even now, decades into the franchise, pokemon evolved by trading remain a point of massive contention and genuine nostalgia for the community.
It’s a mechanic that feels both brilliant and incredibly frustrating. You spend hours leveling up a Machoke, only to realize that no matter how many Rare Candies you feed it, it’s never becoming a Machamp unless you let it go—even if just for a second.
The Original Four and the Link Cable Era
In Red, Blue, and Yellow, the list was short. Golem, Machamp, Gengar, and Alakazam. That was it. But these weren't just random additions; they were some of the most powerful competitive threats in the Kanto region. Alakazam’s Special stat was legendary before the physical/special split, and Gengar was the only Ghost-type line that mattered.
Imagine being a kid in the 90s. You finally find someone with a Link Cable. You’re nervous. You trade your Haunter, it evolves on their screen, and you just have to hope they give it back. This social contract is the backbone of the entire series. It created a "trading economy" long before we had the Global Trade System (GTS) or the Wonder Trade.
Honestly, the fear of getting "scammed" out of a Gengar was a rite of passage.
When Items Made Things Complicated
Then came Gen 2. Gold, Silver, and Crystal didn't just want you to trade; they wanted you to find rare, obscure items first. This is where we got Scizor and Steelix. To get them, your Scyther or Onix had to be holding a Metal Coat during the transfer.
It added a layer of gatekeeping that felt almost cruel. You had to grind for the item, then find a friend, then do the trade.

- Politoed: Needs a King's Rock (which you could also use for Slowking).
- Porygon2: Needs an Up-Grade.
The logic here was basically to showcase the new "Held Item" mechanic. It worked, but it made completing the Pokedex a nightmare for solo players. If you were playing on a localized cartridge without access to a second console, you were basically locked out of 10% of the game's power ceiling.
The Karrablast and Shelmet "Gimmick"
By the time we hit Gen 5 (Black and White), Game Freak started getting experimental. They introduced Karrablast and Shelmet. These two don't just evolve by trading; they have to be traded for each other.
The lore is actually pretty cool. Karrablast is a bit of a bully. During the trade, it literally steals the shell off Shelmet’s back. Karrablast becomes the armored Escavalier, while the naked, speedy Shelmet becomes Accelgor. It’s a rare moment where the gameplay mechanic perfectly mirrors the biological flavor text.
But try explaining that to a casual player without a guidebook. It's confusing. You trade a Karrablast for a Magikarp? Nothing happens. You need that specific interaction.
Modern Workarounds and the Legends: Arceus Shift
For years, the community begged for a way to evolve these Pokemon without needing a second person. We’ve all been there—scouring Reddit or Discord looking for a "tradeback" partner, hoping they don't steal your shiny Phantump.
Then Pokemon Legends: Arceus changed everything.

The introduction of the Linking Cord item was a massive shift. Finally, a consumable item that mimicked the trade effect. You could just use it on a Graveler and—boom—Golem. No internet connection required. Fans loved it. It felt like Game Freak finally acknowledged that some people just want to play alone.
However, in Scarlet and Violet, they went right back to the old ways. Except for some specific Tera Raid encounters where you can catch fully evolved forms like Gengar or Scizor, the trade requirement is still very much alive.
The Unspoken Rules of Trade Evolutions
If you're looking to complete your Dex today, you've gotta follow the unwritten code.
- The Same-for-Same Rule: If you need a Milotic, find someone else who also needs a Milotic. Trade your Feebas (with the Prism Scale) for their Feebas (with the Prism Scale). Everyone wins.
- The "Everstone" Troll: Never be the person who sends a Haunter holding an Everstone. This is a legendary jerk move popularized by an NPC named Mindy in Diamond and Pearl. Don't be Mindy.
- Check the GTS Carefully: People on the GTS often ask for impossible trades (like a level 1-10 Charizard) in exchange for trade-evolved mons. Don't waste your time.
Why We Still Do It
Why hasn't this mechanic been scrapped? It’s because it creates value.
When you see a Machamp in the wild (or in a competitive match), there's a history there. It represents an interaction. Even if that interaction was just with yourself using two Switches, it's a hurdle you cleared. Pokemon has always been about "Gotta Catch 'Em All," but the "together" part is what kept the brand alive during the lean years.
Real-World Steps for Your Next Trade
Don't just jump into a trade blindly. If you're sitting on a Porygon and you want a Porygon-Z, you have a multi-step process ahead of you.

First, get your Porygon. Then, find an Up-Grade. Trade it to evolve into Porygon2. Then—and this is the annoying part—you have to back out of the trade, exit the menu, give Porygon2 a Dubious Disc, and trade it again.
It’s tedious. It’s expensive in terms of in-game currency or BP. But it's the only way.
If you're struggling to find partners, the best place is usually specific Subreddits like r/pokemontrades or dedicated Discord servers. Just make sure to check the "flair" of the person you're trading with to ensure they have a history of being honest.
Actionable Insights for Collectors:
- Capture Higher Forms in Raids: In Sword/Shield and Scarlet/Violet, 5-star and 6-star raids often feature trade-only Pokemon. This bypasses the trade mechanic entirely.
- Use Pokemon Home: You can sometimes find reasonable trades on the mobile version of Home using the GTS.
- The "Linking Cord" hope: Keep an eye on future DLC or titles. Game Freak tends to toggle the "Linking Cord" availability based on whether the game is a "mainline" entry or a "spin-off" style like Arceus.
- Verify the Item: Always double-check that your Pokemon is actually holding the required item before hitting 'Accept.' Once the trade starts, there’s no turning back, and you might lose a rare held item for nothing.
The trade evolution isn't going anywhere. It's frustrating, sure, but it's part of the DNA of the series. Just make sure you have a reliable friend—or at least a very stable internet connection.
