Pokemon Go Thundurus Therian Forme Raid Guide: Best Counters, Weaknesses, Raid Hours, And More Tips

Thundurus Therian Forme makes its triumphant return to Pokemon Go raids during mid-April.

Trainers across the globe will soon encounter this formidable Legendary Pokemon from the Unova region as it takes center stage in five-star raid battles. The electric powerhouse follows its counterpart Tornadus Therian Forme’s recent appearance, continuing the rotation of Therian Forme legendaries throughout the Season of Alola.

Mark your calendars for Thundurus Therian Forme’s raid window from April 5 at 10 AM local time through April 12 at 8 PM local time. Unlike standard raid bosses that follow predictable spawn patterns, Thundurus appearances can be inconsistent across gyms. However, the game’s raid tracking system provides real-time notifications about active raid locations, so diligent monitoring will reveal opportunities.

For those seeking guaranteed access, the weekly Raid Hour on Wednesday, April 6 from 6 PM to 7 PM local time offers the perfect solution. During this dedicated hour, nearly every active gym will feature Thundurus Therian Forme, making it the ideal time to coordinate with fellow trainers for multiple raid attempts. This concentrated appearance window significantly increases your chances of successful capture without the usual location hunting challenges.

Understanding Thundurus Therian Forme’s unique Electric- and Flying-type combination is crucial for assembling an effective counter team. This dual typing creates an unusual defensive profile with limited vulnerabilities but significant resistances that can trap unprepared trainers.

Ice-type and Rock-type attacks deliver super effective damage against this legendary beast. While no currently available Pokemon share this ideal dual typing, several powerful options can exploit these weaknesses effectively. Alolan Ninetales stands out as a premier choice due to its pure Ice typing that avoids vulnerability to Thundurus’s Electric attacks while dealing massive damage with Ice-type moves like Powder Snow and Avalanche.

Rock-type specialists like Lycanroc (especially the Midday Form) with Rock Throw and Stone Edge can dish out substantial damage quickly. Sudowoodo, while less powerful, provides a budget-friendly alternative with similar move sets. The legendary titans Regirock and Regice offer exceptional bulk that allows them to survive multiple charged attacks while steadily chipping away at Thundurus’s health.

For optimal performance, prioritize Pokemon with high attack stats and type-advantaged fast moves to maximize damage output. Beartic with Ice Fang and Ice Punch provides another solid option, particularly if you lack the premium counters. Remember that move selection is equally important as Pokemon choice—ensure your team members have their ideal move sets before engaging.

Thundurus Therian Forme’s defensive capabilities shouldn’t be underestimated. With six type resistances compared to only two weaknesses, this Pokemon can easily neutralize poorly planned assault teams. Understanding what doesn’t work is as important as knowing what does.

Avoid bringing Bug-, Fighting-, Flying-, Grass-, Ground-, and Steel-type Pokemon entirely, as their attacks will deal significantly reduced damage. This resistance pattern means that popular counters like Machamp, Excadrill, or Scizor that work against other raid bosses will be nearly useless here.

The Ground-type resistance is particularly noteworthy since many trainers instinctively reach for Ground types against Electric Pokemon. However, Thundurus’s Flying secondary typing negates this traditional advantage, making Garchomp, Rhyperior, and other Ground attackers poor choices despite type intuition.

Common mistakes include using Electric-resistant Pokemon without considering their offensive capabilities. While these Pokemon might survive longer, they won’t contribute meaningful damage toward defeating the raid boss within the time limit. Focus on survival through type-neutral matchups rather than resistant ones if ideal counters are unavailable.

Successfully defeating Thundurus Therian Forme requires more than just proper type matching. Several advanced strategies can significantly improve your success rate and resource efficiency during this limited raid window.

Weather conditions play a crucial role in raid performance. Partly Cloudy weather boosts Rock-type moves, making your Lycanroc and Regirock even more potent. Snow weather enhances Ice-type attacks, providing substantial damage increases for Alolan Ninetales, Beartic, and Regice. Plan your raid sessions around favorable weather patterns when possible.

Team coordination is essential—aim for groups of 4-6 trainers with properly prepared teams. Smaller groups may struggle to defeat Thundurus within the time limit, especially if using suboptimal counters. Pre-arrange raid teams through local Discord servers or other community platforms to ensure adequate participation.

Maximize Premier Ball rewards by raiding with friends to activate friendship damage bonuses. Ultra Friends provide a significant 2x damage multiplier that can make the difference between victory and defeat in marginal situations. Prepare your teams in advance by powering up key counters and ensuring they have the correct moves to minimize last-minute preparation stress.
