Shadow Giratina (Altered Forme) Raid Guide: Best Counters and Team Building

Shadow Giratina (Altered Forme) is available in Shadow Raids on weekends from August 5 through September 8, 2026. As a Ghost/Dragon-type with inflated Shadow-bonus stats, it hits hard and requires a team built around its specific weaknesses rather than generic “strong attackers.”

Typing and weaknesses

Giratina (Altered Forme) is dual Ghost/Dragon. Cross-referencing both types against the full effectiveness chart, it’s weak to Dark, Dragon, Fairy, Ghost and Ice-type attacks — and because Shadow Pokémon deal and take extra damage compared to their normal counterparts, fights against Shadow Giratina resolve faster (in both directions) than against a standard raid boss of the same species.

Top-tier counters

If you have access to Mega Evolutions, Shadow Pokémon or top-tier Legendaries, the strongest options currently recommended by the raiding community include:

• Eternatus — Dragon/Poison typing and a strong Dragon-type moveset make it one of the single best answers.
• Mega Rayquaza — extremely high Attack stat plus the team-wide Mega boost to Dragon and Flying damage.
• Black Kyurem — Dragon/Ice dual typing hits both of Giratina’s weaknesses at once.
• Mega Garchomp — a reliable, hard-hitting Dragon/Ground option.
• Necrozma (Dawn Wings) and Mega Mewtwo Y — strong Psychic/Ghost-adjacent coverage options for trainers who have them available.

Budget counters (no Mega Energy or Shadow required)

You don’t need a fully optimized roster to win this raid in a group. Strong, accessible picks include:

• Baxcalibur — a newer Dragon/Ice pseudo-legendary with excellent raw stats.
• Haxorus — a pure Dragon-type attacker that’s been a reliable raid pick for years.
• Garchomp — even without its Mega Evolution, base Garchomp remains a strong Dragon/Ground attacker.

Any of these three, run in multiples across a group of four to six trainers, should comfortably take down Shadow Giratina without needing rare resources.

Moveset tips

Prioritize Pokémon running same-type Dragon, Dark, Fairy, Ghost or Ice moves specifically — a Dragon-type Pokémon using a Normal-type Charged Attack, for example, won’t get the super-effective bonus even though the species itself resists Giratina’s attacks. Check each of your raid attackers’ actual moveset in-game before joining a lobby, not just their species and type.

Group size recommendation

Shadow raid bosses hit harder than their non-Shadow versions, so even with strong counters, plan for a group of at least three to four trainers unless your attackers are heavily powered up and using recommended movesets. Remote Raid Passes make it easy to fill out a lobby if you can’t find nearby trainers at raid time.

Why Shadow raids hit differently than normal raids

Shadow Pokémon carry a passive damage bonus compared to their non-Shadow counterparts, in exchange for reduced Defense. As a raid boss, that trade-off shows up as a noticeably faster, more aggressive fight: Shadow Giratina will burn through your team’s HP quicker than a standard Giratina raid would, but it also goes down faster once your attackers land their hits, since the boss’s own defensive stat is lowered. In practice this means bringing shields of your own (healthy, high-level attackers you’re willing to lose mid-fight) matters more here than in an equivalent non-Shadow raid.

Is Shadow Giratina worth catching after the fight?

Yes, for two reasons. First, a Shadow Pokémon you personally own gets the same offensive damage bonus in your hands that the raid boss had against you, making it a strong attacker for other content once “purified” or kept in Shadow form (purifying removes the Shadow bonus but also removes certain drawbacks and unlocks a unique Charged Attack in many cases). Second, Giratina (Altered Forme) itself is a strong neutral Ghost/Dragon attacker in Master League and certain Ultra League formats, so a well-rolled catch has value beyond just the raid encounter itself.

Timing your attempts across the event’s weekends

Because this raid runs on a recurring weekend schedule through September 8 rather than as a single one-off event, there’s no need to rush every available window. If your first weekend’s raid group underperforms or you don’t have your strongest counters powered up yet, you have several more weekends to try again — use the early attempts to figure out which of your Pokémon perform best against Giratina’s actual moveset before committing further Stardust to power-ups.

Altered Forme vs. Origin Forme: don’t mix them up

Giratina has two distinct formes with different implications for team building. Altered Forme (covered in this guide) is the one commonly seen in raids. Origin Forme, accessed with a special item outside of raids, leans harder into Attack rather than bulk. Both formes share the same type weaknesses, so the counters in this guide apply either way, but the boss’s effective bulk and the group size you’ll need can differ — check the raid details screen in-game before assuming which forme you’re facing.

Should solo players even attempt this raid?

Solo-ing a five-star or Shadow raid boss is possible in principle but requires a heavily optimized, high-level roster built specifically around the boss’s weaknesses, plus careful use of dodging to minimize incoming damage. For most trainers, Shadow Giratina is not a realistic solo target — the honest recommendation is to find at least two or three other trainers, whether in person or via a Remote Raid Pass through an online raid-coordination community. There’s no shame in needing a group; even veteran players with strong rosters typically raid Shadow-tier bosses in twos and threes rather than alone, simply because it’s faster and safer for everyone’s Raid Pass investment.
