How to Change Keldeo Form in Pokémon GO

Keldeo is a Mythical Water- and Fighting-type Pokémon that debuted in Generation V and later made its way into Pokémon GO through limited-time Special Research, making it a prized catch for collectors. As a member of the Swords of Justice alongside Cobalion, Terrakion, and Virizion, Keldeo stands out not just for its rarity, but for its unique ability to switch between two different forms, each tied to a specific battle role. These forms aren’t just visual changes—they directly affect the moves Keldeo can learn, which can completely change how it performs in raids, PvP, or general battles. Understanding how these forms work and how to swap between them is essential if you want to get the most value out of this Mythical Pokémon, so below we’ll clearly break down what each form offers and explain the exact steps needed to change Keldeo’s form in-game.

Keldeo Forms in Pokemon Go

Keldeo has two separate forms available in Pokémon GO, and the difference between them goes far beyond looks. The first is Ordinary Form, which is the version you receive by default after catching Keldeo. In this state, it keeps its classic design and is limited to standard Charged Moves, meaning its battle potential is solid but not exceptional. The second option is Resolute Form, which shifts Keldeo into a more aggressive, combat-focused stance with a longer horn and distinct colored plumes on its head. What truly sets this form apart is access to Keldeo’s exclusive Charged Move, Secret Sword, a hard-hitting Fighting-type attack that Ordinary Form cannot use at all. Secret Sword dramatically boosts Keldeo’s effectiveness, pushing it into top-tier territory among non-Mega Fighting-type attackers for raids and combat-focused content. Once Keldeo is taught Secret Sword, the move is locked in and cannot be removed with standard Charged TMs, so choosing Resolute Form is effectively a long-term decision unless you intentionally switch the form back later.

How to Change Keldeo Form

Switching Keldeo into its stronger form in Pokémon GO isn’t instant and requires a bit of preparation first. Before the option even appears, you must complete the Tales of Transformation Special Research all the way to its final step. On top of that, you’ll need 50 Keldeo Candy and 10,000 Stardust, which act as the cost for unlocking the transformation. Once everything is ready, the process itself is simple: open your Pokémon storage, tap on Keldeo, and scroll down its profile page until you find the Change Form option. Confirm the choice, and Keldeo will immediately shift into Resolute Form, automatically learning its exclusive Charged Move, Secret Sword. If you don’t see the form change option at first, double-check that Keldeo isn’t currently set as your Buddy and restart the app if needed. While the transformation isn’t permanent and can be undone later, switching back will cost the same amount of Candy and Stardust again, so it’s best to be sure before committing.

FAQs

Can Keldeo change forms more than once?

Yes, Keldeo can switch between Ordinary Form and Resolute Form whenever you want, as long as you pay the cost each time. Every form change requires 50 Keldeo Candy and 10,000 Stardust, so it’s not something you’ll want to do repeatedly without planning.

Does changing Keldeo’s form affect its stats?

No, Keldeo’s base stats stay exactly the same in both forms. The real difference comes from its moveset, since Resolute Form unlocks access to Secret Sword, which makes a huge difference in battle performance.

Can Ordinary Form learn Secret Sword?

No, Secret Sword is exclusive to Resolute Form only. If Keldeo is in its Ordinary Form, that move will not be available under any circumstances, even with Charged TMs or Elite TMs.

Is Secret Sword removable once learned?

Once Keldeo learns Secret Sword, it cannot be replaced using normal Charged TMs. The only way to remove it is by changing Keldeo back to Ordinary Form, which also removes access to that move.

Is Resolute Form worth unlocking?

For most players, yes. Resolute Form turns Keldeo into one of the strongest non-Mega Fighting-type attackers in Pokémon GO, making it especially valuable for raids and high-level battle content. If you plan to actually use Keldeo instead of just collecting it, the form change is usually worth the investment.

Conclusion

Changing Keldeo’s form in Pokémon GO is more than just a cosmetic upgrade, it’s a meaningful decision that directly impacts how useful this Mythical Pokémon is in battle. While Ordinary Form works fine for collection purposes, unlocking Resolute Form and Secret Sword turns Keldeo into a serious Fighting-type powerhouse that can compete with the best non-Mega attackers in the game. As long as you’ve completed the required Special Research and are ready to spend the Candy and Stardust, the form change process is straightforward and fully reversible if you ever change your mind. If you’re looking to get real value out of Keldeo rather than letting it sit in storage, understanding and using its form change is absolutely worth it.
