Mega Swampert is a dual Water- and Ground-type Pokémon that possesses a notable double-weakness to Grass-type attacks. Due to its unique typing, it only has this single vulnerability. A well-prepared team of high-DPS Grass-type Pokémon can bring it down with incredible efficiency.
Mega Swampert will return to Mega Raids from Wednesday, August 19, at 6:00 a.m. local time. It will be available until Tuesday, August 25, at 9:00 p.m. local time.
Bringing the right counters will make all the difference if you are planning to farm Mega Energy, hunt for a shiny, or simply add Mega Swampert to your collection.

Best Mega Swampert Counters
The following are the top Pokémon that deal super-effective damage to Mega Swampert.
| POKÉMON | RECOMMENDED MOVESET |
| Mega Sceptile | Bullet Seed as a Fast Attack and Frenzy Plant as a Charged Attack |
| Kartana | Razor Leaf as a Fast Attack and Leaf Blade as a Charged Attack |
| Shaymin (Sky) | Magical Leaf as a Fast Attack and Grass Knot as a Charged Attack |
| Mega Venusaur | Vine Whip as a Fast Attack and Frenzy Plant as a Charged Attack |
| Shadow Chesnaught | Vine Whip as a Fast Attack and Frenzy Plant as a Charged Attack |
| Shadow Sceptile | Bullet Seed as a Fast Attack and Frenzy Plant as a Charged Attack |
| Zarude | Vine Whip as a Fast Attack and Power Whip as a Charged Attack |
| Shadow Tangrowth | Vine Whip as a Fast Attack and Power Whip as a Charged Attack |
| Shadow Venusaur | Vine Whip as a Fast Attack and Frenzy Plant as a Charged Attack |
| Shadow Torterra | Razor Leaf as a Fast Attack and Frenzy Plant as a Charged Attack |
Note that Grass-type attackers play heavily into Mega Swampert’s double-weakness, making them the absolute highest priority. Legendary and Shadow options output massive damage, but standard Grass types will easily pull their weight.
Mega Swampert Raid Boss Moveset
When battling Mega Swampert in raids, it will utilize its own set of Fast and Charged attacks. Being aware of its moveset helps you anticipate incoming damage:
Fast Attacks: Water Gun (Water), Mud Shot (Ground)
Charged Attacks: Earthquake (Ground), Sludge (Poison), Sludge Wave (Poison), Surf (Water), Muddy Water (Water), and Hydro Cannon (Water). (Note: Watch out for Sludge Wave if you are bringing certain Grass-type counters like Tapu Bulu or Exeggutor that don’t resist poison well!)
Resistances: Avoid bringing Pokémon that rely on Electric, Fire, Poison, Rock, or Steel-type attacks, as Mega Swampert resists these damage types.
Best Mega Swampert Budget Counters
Not everyone currently has access to high-tier Shadow Pokémon or rare legendary grass options. Fortunately, Mega Swampert’s double-weakness makes it accessible with strong non-legendary choices. Excellent budget choices are as follows:
Chesnaught with Vine Whip as a Fast Attack and Frenzy Plant as a Charged Attack.
Torterra with Razor Leaf as a Fast Attack and Frenzy Plant as a Charged Attack.
Tangrowth with Vine Whip as a Fast Attack and Power Whip as a Charged Attack.
Venusaur with Vine Whip as a Fast Attack and Frenzy Plant as a Charged Attack.
Leafeon with Razor Leaf as a Fast Attack and Leaf Blade as a Charged Attack.
Roserade with Razor Leaf as a Fast Attack and Grass Knot as a Charged Attack.
Mega Swampert Raid Tips
Having the best counters may not be enough. You also need a good strategy. The following tips will help you a great deal:
Lead with a Mega Grass Pokémon (like Mega Sceptile or Mega Venusaur) to boost teammates’ corresponding Grass attacks. Remember, you can only use one Mega/Primal Pokémon per lobby.
Coordinate Mega Evolutions with your raid group for maximum efficiency.
Use Pokémon with matching Fast and Charged Moves (e.g., full Grass-type sets).
Revive and rejoin if necessary rather than using weaker backup teams.
If you can, battle Mega Swampert during Sunny/Clear weather conditions in-game for an extra Grass-type damage boost.
How Many Trainers are Needed?
Due to Mega Swampert’s double weakness to Grass-type attacks, it is significantly less resilient than other Mega Raid bosses. In ideal conditions with top-tier counters like Mega Sceptile or Shadow Sceptile, it can even be defeated by a single ultra-prepared player. However, for most trainers utilizing standard or budget counters, a group of 2 to 4 players will comfortably secure the win.4
Hundo CP for Swampert from Raids
You will get rewards such as Swampert Mega Energy, items, and an encounter with regular Swampert after completing the Mega Raid successfully.
The hundo CP (i.e., the perfect IV CP) for Swampert caught from raids depends on the in-game weather condition when it was caught. If caught during Sunny (boosts Grass) or Rainy (boosts Water) weather conditions, the hundo CP is 2124 CP. Otherwise, the standard hundo CP (Level 20) is 1699 CP.
For a complete overview of what to expect when catching Swampert post-raid, keep an eye out for these CP ranges:
Standard Catch CP (Level 20): 1622 – 1699 CP.
Weather Boosted Catch CP (Level 25): 2027 – 2124 CP.
If you get a good one, teach it Mud Shot as a Fast Attack and Hydro Cannon (Legacy) and Earthquake as Charged Attacks for its premier water/ground raid roles.
