In Pokémon GO, raids are the ultimate test of a trainer's strength. Whether you are facing a Tier 5 Legendary or a massive Mega Evolution, the clock is your biggest enemy. To succeed, you don't just need strong Pokémon; you need the best attackers for raids that can deal the maximum amount of damage in the shortest time possible.

In this guide, we will break down the top-tier attackers in the current meta. We will explore the difference between DPS and TDO, the power of Shadow Pokémon, and a type-by-type breakdown of which monsters you should be powering up to dominate your next raid battle.

1. Why DPS is the Most Important Metric in Raids

When you are battling in a Gym or the GO Battle League, you might prioritize bulk and defense. However, in raids, DPS (Damage Per Second) is king. Raids are timed encounters. If the timer hits zero, you lose, even if your Pokémon are still standing.

TDO (Total Damage Output) is also important—it represents how much damage a Pokémon does before it faints—but if a Pokémon takes too long to deal that damage, it isn't helping you beat the clock. The best raid attackers strike a balance between high DPS to beat the timer and enough TDO to ensure you aren't spending the whole raid in the "rejoin" screen.

2. The Hierarchy of Raid Power: Shadows, Megas, and Primals

Before looking at specific types, it is important to understand the three "boosted" categories of Pokémon that sit at the top of the food chain.

Shadow Pokémon

Shadow Pokémon receive a 20% attack bonus in exchange for a 20% reduction in defense. In raids, this trade-off is almost always worth it. A Shadow Pokémon with mediocre IVs will often out-damage a non-shadow 100% IV version of the same species. If you want the fastest clear times, Shadow attackers are essential.

Mega Evolutions and Primal Reversion

You can only have one Mega or Primal Pokémon on your team at a time. Not only do these Pokémon have massive stats, but they also provide a damage boost to every other player in the raid. If your Mega is on the field, all other players deal 10% more damage (and 30% more damage for moves that match the Mega Pokémon's type).

3. Best Fire-Type Attackers

Fire types are frequently needed for Bug, Grass, Ice, and Steel-type Raid Bosses (like Registeel or Kartana).

  • Mega Blaziken: Currently the highest DPS Fire type. Its Fire Spin and Blast Burn combo is devastating.
  • Reshiram: The king of non-Mega Fire types, especially if it has its signature move, Fusion Flare.
  • Shadow Entei / Shadow Moltres: Both provide incredible consistent damage.
  • Shadow Chandelure: A glass cannon that deals massive damage very quickly.

4. Best Water-Type Attackers

Water types are the primary counters for Fire, Ground, and Rock-type bosses (like Primal Groudon or Terrakion).

  • Primal Kyogre: The absolute gold standard. It is arguably one of the most powerful Pokémon in the entire game. Its signature move, Origin Pulse, is a must-have.
  • Mega Swampert: A fantastic alternative to Kyogre with a very fast-charging Hydro Cannon.
  • Shadow Feraligatr: With the move Hydro Cannon, it has recently climbed the ranks to become a top-tier Shadow attacker.
  • Greninja: Specifically with Hydro Cannon (from Community Day), it is the best non-Legendary/non-Shadow Water type.

5. Best Grass-Type Attackers

Grass types excel against Water, Ground, and Rock types. They are essential for raids like Kyogre or Swampert.

  • Kartana: This Ultra Beast has an astronomical Attack stat. It is the highest DPS Grass type in the game, even outperforming most Megas. Its move Leaf Blade is incredibly efficient.
  • Mega Sceptile: The fastest Grass attacker, though it is quite "glassy" and faints quickly.
  • Shadow Tangrowth / Shadow Venusaur: Both are very reliable "bulky" attackers that deal great damage.

6. Best Electric-Type Attackers

Electric types are your go-to for Water and Flying-type bosses (like Lugia or Kyogre).

  • Xurkitree: Another Ultra Beast with massive raw power. It currently holds the crown for non-Mega Electric DPS.
  • Mega Manectric: Provides great damage and a type boost for other players.
  • Zekrom: With Fusion Bolt, Zekrom is a powerhouse that also has the bulk to survive several Charged Moves from the boss.
  • Shadow Raikou / Shadow Magnezone: Excellent consistent damage dealers.

7. Best Psychic-Type Attackers

While Psychic types have fewer type advantages (mostly Fighting and Poison), they are often used for their raw neutral DPS.

  • Mewtwo: The legendary king. Shadow Mewtwo with Psystrike is widely considered the best overall attacker in Pokémon GO history. Even regular Mewtwo outclasses almost everything else.
  • Mega Alakazam / Mega Latios: Great for boosting Psychic damage in groups.
  • Shadow Metagross: While usually a Steel attacker, it can function as a secondary Psychic type if needed.

8. Best Dragon-Type Attackers (The Supreme Overlords)

Dragons are unique because they are only "Super Effective" against other Dragons. However, they have such high base stats that they are often the best "neutral" attackers in the game.

  • Mega Rayquaza: The strongest Pokémon currently in the game. With its signature move Dragon Ascent (which is actually a Flying move, but makes it a monster), it achieves DPS levels that were previously thought impossible.
  • Mega Garchomp / Mega Salamence: Incredible Dragon-type powerhouses.
  • Shadow Salamence / Shadow Dragonite: If you don't have a Mega evolved, these are your best bets for raw Dragon damage.
  • Dialga / Palkia (Origin Forms): With their signature moves (Roar of Time and Spacial Rend), these are top-tier legendary picks.

9. Budget Attackers: How to Win Without Legendaries

Not everyone has a team of six Shadow Mewtwos. If you are a beginner or a free-to-play player, these "budget" options are easy to obtain and still perform exceptionally well:

  • Machamp: Easy to get via Machop. Excellent against Normal, Rock, and Ice types.
  • Roserade: A top-tier Grass and Poison attacker that only requires Roselia candy.
  • Chandelure: Litwick is often featured in events. Chandelure is a top Fire and Ghost attacker.
  • Eeveelutions: Glaceon (Ice), Espeon (Psychic), and Flareon (Fire) are the ultimate budget "fillers" for any raid team.
  • Haxorus: After its Community Day, Haxorus became a very accessible and high-DPS Dragon type.

10. How to Build the Perfect Raid Team: Movesets and IVs

Having the right Pokémon is only half the battle. You must also ensure they have the correct moves.

The Right Moveset

A Pokémon with the wrong moves is useless. For example, a Mewtwo with Thunderbolt isn't going to help you in a Psychic-weak raid. Always use Fast TMs and Charged TMs to ensure your Pokémon has its best type-specific moveset. Use online databases or apps like PokeGenie to check for "Legacy Moves" that might require an Elite TM.

The Truth About IVs

Trainers often obsess over "100% IVs." However, in raids, IVs matter very little compared to level and moveset. A 0% IV Kartana will deal significantly more damage than a 100% IV Venusaur. While you should aim for high Attack IVs, don't let a "two-star" legendary stop you from using it if it's the best counter you have.

11. Conclusion

Building a top-tier raid team in Pokémon GO is a marathon, not a sprint. Start by identifying which types you are missing and fill those gaps with budget attackers like Eeveelutions or Machamp. As you participate in more raids, start collecting Legendary Pokémon and Shadow Pokémon to replace them.

Remember to always prioritize Mega Rayquaza, Primal Kyogre, Primal Groudon, and Shadow Mewtwo, as these four are the cornerstones of any elite raid collection. With the right movesets and a bit of Stardust, you'll be able to carry your group to victory and catch those elusive legendary Shinies!

Happy raiding, Trainers!
