The best chance Pokemon GO players will have at defeating Ninjask solo in raids is if their Pokemon are weather-boosted. However, it’s still possible to beat a Ninjask raid solo with no weather boost if players have powered-up the right Pokemon. The absolute best Pokemon for the job is Rampardos with Smack Down and Rock Slide, so ideally a Pokemon GO player who wants to beat a Ninjask raid solo will have a full team of properly-equipped Rampardos.
However, Rampardos was added to Pokemon GO fairly recently, and so it’s unlikely that many Pokemon GO players will have a full, powered-up team of Rampardos available. Luckily there are some other Pokemon that serve as great counters for Ninjask who will go a long way in helping Pokemon GO players beat the Ninjask raid solo.
Best Ninjask Raid Counters
Rampardos - Smack Down/Rock Slide Tyranitar - Smack Down/Stone Edge Rhyperior - Smack Down/Stone Edge Omastar - Rock Throw/Rock Slide Golem - Rock Throw/Stone Edge Rayquaza - Air Slash/Ancient Power Regirock - Rock Throw/Stone Edge Heatran - Fire Spin/Stone Edge Moltres - Fire Spin/Sky Attack
If Pokemon GO players are having a hard time putting together a team of the above Pokemon, then there are some other choices that, while not quite as effective, can still help them beat the Ninjask raid solo.
Decent Ninjask Raid Counters
Sudowoodo - Rock Throw/Rock Slide Melmetal - Thunder Shock/Rock Slide Electivire - Thunder Shock/Wild Charge Mamoswine - Powder Snow/Ancient Power Entei - Fire Spin/Overheat
Using a combination of the above Pokemon, Pokemon GO players that are high enough level should be able to solo Ninjask raids and add the rare bug-type Pokemon to their collection. Ninjask is likely to leave Pokemon GO raids once the Bug Out event is over, though, so anyone interested should act fast.
