AI Summary

To change Keldeo from Ordinary Form to Resolute Form in Pokémon GO, open Keldeo's summary page, tap Change Form, and confirm the cost of 50 Keldeo Candy and 10,000 Stardust. The button appears only after you reach the relevant form-change step in Keldeo's Special Research.

Cost per change: 50 Keldeo Candy + 10,000 Stardust
Resolute Form automatically receives Secret Sword
Typing and base stats do not change
Changing back costs the same resources again and removes Secret Sword

Keldeo form-change requirements

Owning Keldeo and having enough Candy is not always sufficient. Pokémon GO ties the feature to the Keldeo research story that contains the form-change objective.

Requirement	Current rule
Eligible Keldeo	An Ordinary Form Keldeo in your Pokémon storage
Research progress	Reach the task that asks you to change Keldeo's form
Candy	50 Keldeo Candy per change
Stardust	10,000 Stardust per change

Accounts that claimed the 2025 seasonal story use Tales of Transformation. Pokémon GO later made Keldeo available through a follow-up research path after Finding Your Voice; current player-facing documentation refers to that Keldeo story as Hooves of a Hero. Follow whichever Keldeo research is present on your account rather than looking for a retired event tab.

How to change Keldeo into Resolute Form

Open the main menu and select Pokémon.
Search for Keldeo and open its summary page.
Scroll below the power-up controls and tap Change Form.
Review the preview and the 50-Candy, 10,000-Stardust cost.
Confirm the change. Keldeo becomes Resolute Form and receives Secret Sword as its Charged Attack.

Form changing is reversible, but it is not a free appearance toggle. Every switch charges the resources again, so repeatedly moving between forms can drain scarce Keldeo Candy.

Ordinary Form vs Resolute Form

Both forms remain Water- and Fighting-type and keep the same base stats. The meaningful gameplay change is the Charged Attack.

Feature	Ordinary Form	Resolute Form
Typing	Water / Fighting	Water / Fighting
Base stats	Unchanged	Unchanged
Signature move	Cannot retain Secret Sword	Secret Sword is added during the form change
Appearance	Short horn and plain mane	Long horn and colored plumes

Niantic's official debut announcement lists Secret Sword at 70 power in Trainer Battles and 120 power in Gyms and raids. Those values explain why the form matters even though Keldeo's typing and stats stay fixed. For wider team planning, compare current Pokémon GO gym attackers instead of assuming one Mythical fits every matchup.

Why is the Change Form button missing?

Your research is not far enough. Progress until the Keldeo story explicitly asks for the form change.
You are viewing the wrong Keldeo or account. Confirm the Pokémon is in the same account that owns the research.
The app has stale data. Update Pokémon GO, restart it, and use Settings > Advanced Settings > Refresh Game Data if the completed research is not reflected.
Keldeo is assigned as your Buddy. If the game blocks the action, swap Buddies temporarily and try again; this is a commonly reported UI restriction rather than a published cost rule.

Do not spend Charged TMs trying to unlock the button. Secret Sword is tied to the Resolute form-change process, not to ordinary TM rolls.

Keldeo form-change FAQ

Can you change Keldeo back to Ordinary Form?

Yes. Tap Change Form again and pay another 50 Keldeo Candy and 10,000 Stardust. Secret Sword is replaced when Keldeo returns to Ordinary Form.

Can an Elite Charged TM teach Secret Sword?

No current official instruction lists an Elite TM as the unlock method. Secret Sword is granted by changing Keldeo into Resolute Form.

Does changing form reroll Keldeo's IVs or CP?

No. It is the same Pokémon with the same IVs, level and base stats. The visible CP should not be rerolled by the form change.

Can new players still get Keldeo?

Niantic said trainers who missed Tales of Transformation would receive a new Keldeo Special Research after completing Finding Your Voice. Research availability can depend on prerequisites, so work through your Special Research list. Our Pokémon GO beginner guide explains the surrounding systems.

Is Keldeo one of the rarest Pokémon?

It is research-gated and cannot be farmed like a normal wild spawn, but rarity depends on event access, region and re-releases. See the separate rare Pokémon availability guide for a broader comparison.
