Origin Forme Dialga is a Steel/Dragon-type raid boss, so Fighting- and Ground-type attacks are the counters that matter. Those attacks deal 60% increased damage in the Pokémon GO Hub counter reference. Build a party around your strongest attackers with those move types, then compare their damage per second (DPS), total damage, expected faints, and time to win rather than copying a supposedly universal ranking.
For planning, a third-party guide estimates four to six trainers when everyone has strong counters and the weather is favorable, while seven or more is a safer target with weaker teams or unfavorable conditions. Those numbers are guidelines, not an official minimum: your Pokémon’s levels, moves, dodging, the boss’s moveset, and weather can change the result.
What is Origin Forme Dialga weak to?
Origin Forme Dialga is weak to Fighting- and Ground-type attacks. Its Steel/Dragon typing gives those two attack types the relevant super-effective advantage; the Pokémon GO Hub counter reference displays 60% increased damage for each.
Build around Fighting and Ground moves
When you inspect a possible counter, check both its Fast Attack and Charged Attack. A Pokémon that is technically a Fighting or Ground type but lacks attacks of those types may perform worse than a different species with the right moves. Your objective is a complete attack cycle that repeatedly applies super-effective damage, not simply a favorable defensive label.
| Attack type | When it is useful | What to check |
|---|---|---|
| Fighting | Use when your roster has high-level Fighting attackers with reliable same-type attacks. | Confirm the Fast and Charged moves are Fighting-type and compare the counter’s DPS and time-to-win results. |
| Ground | Use when your strongest available attackers can maintain Ground-type damage. | Check move availability, survivability, expected faints, and whether weather or the boss’s moveset changes the matchup. |
Why there is no single “best six” for every player
Counter pages calculate performance under particular assumptions. The useful fields are DPS, total damage, expected faints, and time to win. A glass-cannon attacker may finish its attacks quickly but faint often; a sturdier option may show lower DPS while contributing damage for longer. Your Pokémon’s level, individual moves, party size, weather, and the raid boss’s moveset all affect the practical result.
A dynamic counter page surfaced in October 2026, but the exact current top-ranked roster and its full move details were not sufficiently verified for a definitive list. Treat any ordered ranking as a starting point. Open each candidate’s details, confirm its moves, and select the strongest Fighting- or Ground-based team you actually own.
Which Origin Forme Dialga raid counters should you choose?
Choose the highest-performing Fighting and Ground attackers in your own storage, using the game’s available levels and moves as the deciding factors. A sensible team normally contains enough attackers to survive several cycles, with backup options ready if the first six faint.
Use this counter checklist
- Super-effective attacks: give priority to Fighting- or Ground-type Fast and Charged moves.
- Damage output: compare DPS and total damage, not just the Pokémon’s Combat Power.
- Endurance: review expected faints and time to win so a high-DPS choice does not leave you waiting through repeated relobbies.
- Move reliability: make sure the Charged Attack can be reached and used consistently during the battle.
- Roster depth: prepare additional Fighting or Ground attackers for the second party if your first group is likely to faint.
- Conditions: account for weather and the boss’s moveset before deciding whether a marginal counter is suitable.
How to compare two otherwise similar attackers
Start with the counter’s time to win. If two options are close, use total damage and expected faints to decide whether one contributes more before needing a relobby. For a small group, endurance can be as important as peak DPS because every faint removes damage until the player returns with another party.
Do not replace a Fighting or Ground attacker solely because another Pokémon has a higher displayed CP. CP does not tell you whether the moves are super effective, how quickly the Charged Attack is generated, or how long the Pokémon remains active.
How many people do you need to beat Origin Forme Dialga?
Plan for four to six trainers with strong counters and favorable weather. With less favorable counters or conditions, plan for seven or more. The estimate comes from a third-party strategy guide and is not an official guaranteed minimum.
| Raid situation | Planning target | Why the target changes |
|---|---|---|
| Strong Fighting/Ground teams and favorable weather | About 4–6 trainers | Higher effective damage lets each player contribute more before fainting. |
| Mixed or weaker counters, poor weather, or uncertain movesets | 7 or more trainers | Extra players provide damage and a buffer for faints, dodging mistakes, and slower teams. |
What can make the estimate wrong?
Trainer count alone does not determine the result. Two six-player groups can perform very differently if one group uses high-level super-effective attackers and the other relies on low-damage or neutral moves. Dodging, connection problems, the boss’s move set, and how quickly players re-enter after fainting can also decide the outcome.
When should a group add more players?
Add another trainer when several participants cannot field a full party of Fighting or Ground attackers, when the lobby contains many new or low-level accounts, or when weather removes the team’s expected advantage. If the raid timer is already running and your opening party is fainting unusually quickly, re-lobbying with a stronger prepared team is safer than repeatedly sending the same weakened lineup.
How do you prepare an Origin Forme Dialga raid party?
Use the following sequence before you spend a Raid Pass. It is designed to prevent the most common preparation errors: wrong move types, insufficient backups, and a group sized for ideal conditions rather than the actual lobby.
- Check the raid and weather. Note whether the encounter is currently boosted and whether the forecast is likely to change before the battle starts. Weather is one of the factors that can alter both planning estimates and the catch encounter.
- Filter your storage. Search for your strongest Fighting- and Ground-capable Pokémon. Inspect their Fast and Charged Attacks instead of assuming a species automatically supplies the needed damage.
- Compare performance. Use DPS, total damage, expected faints, and time to win to rank the candidates you actually have. Favor a balanced six over a lineup that is fast on paper but repeatedly faints before using its Charged Attack.
- Build a second party. Save additional suitable attackers for the event that your first six faint. A backup party shortens the delay before you return to the battle.
- Coordinate the lobby. Share the expected group size and ask teammates whether they have Fighting or Ground counters. If the lobby is below the appropriate planning target for the team quality and weather, wait for more players when possible.
- Review before entering. The recommended party can include convenient but poorly matched choices. Replace any member that does not supply the intended super-effective damage.
- Monitor the first attempt. Watch how quickly the boss’s HP falls and how many attackers faint. If the pace is poor, communicate, add players, or change to the backup party rather than assuming the original estimate guarantees success.
How do weather and catch CP affect the raid?
Weather is relevant to both battle planning and the CP of the Pokémon you may catch afterward. The counter reference lists an Origin Forme Dialga catch CP of 2246–2337 without a weather boost and 2807–2921 with a Snow or Windy weather boost.
| Encounter condition | Reported catch CP range | How to use the number |
|---|---|---|
| No weather boost | 2246–2337 | Use it as a check that the encounter falls within the reported unboosted range. |
| Snow or Windy weather boost | 2807–2921 | Use it as the reported boosted range when the game shows the applicable weather. |
These ranges help identify whether an encounter is weather boosted; CP alone does not establish an individual Pokémon’s appraisal, quality, or future usefulness. Open the in-game appraisal view to evaluate the Pokémon you caught.
Why weather should change your group plan
The published group estimate is explicitly conditional on favorable or unfavorable weather. Treat weather as one input to your risk calculation, not as a promise that a smaller lobby will win. If the forecast or in-game weather differs from what your group expected, use the more conservative trainer target.
Can Origin Forme Dialga give you Roar of Time?
Yes, a raid defeat gives you a chance to catch Origin Forme Dialga knowing the Charged Attack Roar of Time. Niantic’s announcement states: “Trainers who encounter and defeat Origin Forme Dialga in a Raid Battle have a chance to catch one that knows the Charged Attack Roar of Time.” The wording is important: a raid catch is not guaranteed to have the move.
What is the Roar of Time Adventure Effect?
The official announcement says the Adventure Effect costs 5,000 Stardust and 5 Dialga Candy and lasts six minutes. While active, it pauses the timers for Incense, Daily Adventure Incense, Lucky Eggs, and Star Pieces. Confirm that your caught Dialga actually knows Roar of Time before planning around the effect.
Does the old raid-day announcement set the current schedule?
No. The official event page found for a return raid day describes August 10, 2025, which is a historical event date. It also says the move may appear on raid encounters during that event, but that statement should not be treated as a current or future guarantee.
When is Origin Forme Dialga returning to raids?
No current or upcoming Origin Forme Dialga raid date is established by the available sources. Do not present the August 10, 2025 raid day as the next appearance. Check the live in-game raid rotation and a newly published official Pokémon GO event announcement before making travel, pass, or group plans.
What should you do if the raid attempt is failing?
Diagnose the failure instead of simply adding random Pokémon. The symptom usually points to a specific change that will improve the next attempt.
The boss’s HP is dropping too slowly
Inspect the party for neutral or off-type moves, then replace those members with Fighting- or Ground-capable attackers. If the whole group is already using super-effective moves, add trainers or wait for a stronger lobby; the published four-to-six estimate assumes strong counters and favorable conditions.
Your team faints before it deals enough damage
Use the counter fields for expected faints and total damage to identify sturdier alternatives. Prepare a second party before re-entering, and coordinate a simultaneous relobby so the raid does not spend long periods with too few active attackers.
The weather changed after you planned
Recalculate with the less favorable condition. Weather is part of the group-size assumption, so keep the larger target when the expected boost disappears.
The boss’s moveset is causing unexpected losses
The boss’s moves can alter practical performance even when the counter’s type is correct. Favor options with better endurance, dodge when you can do so without losing attack timing, and use the raid’s first phase to judge whether the original team remains viable.
You are relying on the recommended party
Automatic recommendations are a convenience, not a guarantee that every selected Pokémon has the best matchup. Open each recommended Pokémon’s move details and manually assemble a party whose attacks are Fighting or Ground whenever your roster allows it.
What are the most important mistakes to avoid?
- Confusing Origin Forme Dialga with another form. This guide applies to Origin Forme Dialga, not regular Dialga, Shadow Dialga, or Origin Forme Palkia.
- Treating a ranking as permanent. Counter pages can change as game data and move assumptions are updated; verify the current move details before a major raid.
- Using the trainer estimate as a guarantee. Four to six is conditional on strong counters and favorable weather, while seven or more is the safer planning target when conditions are weaker.
- Assuming every catch knows Roar of Time. The official wording says there is a chance, not a certainty.
- Reading catch CP as an appraisal. CP ranges identify the reported encounter bands but do not replace the in-game appraisal screen.
- Planning from an old event date. The August 10, 2025 announcement is historical and does not establish a current raid rotation.
Quick decision framework before you use a Raid Pass
Use this final check at the lobby entrance:
- Are most players bringing Fighting- or Ground-type attacks?
- Does the lobby fit the four-to-six strong-counter estimate, or should you wait for seven or more?
- Has weather changed enough to remove the conditions behind the smaller-group plan?
- Does every player have a backup party ready?
- Are you treating the catch’s possible Roar of Time as a chance rather than a guarantee?
If the answer to any of these questions is no, fix that item before starting when the lobby allows it. A deliberate team built around super-effective moves is more reliable than a larger party assembled without checking attacks.
Frequently Asked Questions
How can I verify that one of my Pokémon has the right attack type?
Open the Pokémon’s detail screen and read the labels for its Fast Attack and Charged Attack. Build the raid party from entries that actually list Fighting or Ground moves; a Pokémon’s species or displayed CP is not enough to confirm the matchup.
Should I power up a new counter immediately before the raid?
Only do so when the upgrade changes your practical team: for example, it replaces a neutral attacker or prevents an early faint. Compare the improved Pokémon’s damage and endurance with the Fighting or Ground options you already have instead of spending resources for a small CP increase.
What does a weather-boosted catch tell me after the raid?
A CP in the reported 2807–2921 range is consistent with the Snow or Windy boosted encounter band. It does not reveal the Pokémon’s individual appraisal, so use the game’s appraisal function for that judgment.
Where should I check whether Dialga is currently available?
Use the live raid rotation shown in Pokémon GO and the newest official event announcement. A dated event page, including the August 10, 2025 return raid day, should not be used as evidence of the next appearance.
