Pokemon GO’s Legendary Heroes event delivered an unexpected gameplay enhancement, creating significant buzz throughout the player community. While most event features were detailed in advance, this hidden evolution mechanic provides collectors and battlers with fresh strategic options. The arrival of Shadow Galarian Weezing represents a major meta-game development, offering both PvP and PvE applications that experienced trainers can leverage.
This surprise addition demonstrates Niantic’s evolving approach to event design, rewarding dedicated players who explore beyond surface-level announcements. The timing coincides perfectly with ongoing Dragon-type raid rotations, making this Poison/Fairy hybrid particularly valuable for countering popular Dragon attackers.
Shadow Galarian Weezing’s dual Poison/Fairy typing creates distinct strategic advantages compared to standard Poison-type variants. This combination provides complete immunity to Dragon-type attacks, making it an excellent counter against prevalent Dragon-type raid bosses and gym defenders. The expanded move pool includes potent Fairy-type charged moves like Dazzling Gleam and Play Rough, which deal super-effective damage against Fighting, Dark, and Dragon types.
However, trainers must carefully manage significant vulnerabilities to Ground, Steel, and Psychic-type moves. These weaknesses can be exploited by common gym defenders like Metagross, Excadrill, and Mewtwo. Understanding these type interactions is crucial for effective deployment in both offensive and defensive scenarios.

Shadow Galarian Weezing in the evolution pool

During the Legendary Heroes event, trainers can evolve Shadow Koffing into the newly available Shadow Galarian Weezing. This evolution path wasn’t included in initial event documentation, creating an exciting discovery element for the community. The evolution requires exactly 50 Pokemon Candies, maintaining consistency with standard Koffing evolution requirements.
Shadow Koffing appears in 1-Star Shadow Raids alongside featured Pokemon including Galarian Ponyta, Darumaka, Goomy, and Jangmo-o. For trainers lacking Shadow Koffing in their collection, this event provides the perfect acquisition opportunity to obtain this rare variant. The candy-efficient evolution process makes this accessible even for players with limited resource stockpiles.
Strategic consideration for players
While Shadow Galarian Weezing introduces exciting new battle possibilities, trainers must carefully evaluate the trade-offs before committing to evolution. The dual typing creates unique offensive capabilities but introduces additional defensive vulnerabilities that require careful team composition. These weaknesses can significantly impact gym defense viability and raid performance if not properly managed through type coverage partners.
Optimal deployment involves pairing with Steel or Ground-type counters to cover the primary weaknesses. In PvP scenarios, the shadow bonus provides approximately 20% attack increase at the cost of similar defense reduction, making timing and switch management critical for success.
Since this evolution feature wasn’t pre-announced, its availability timeline remains uncertain. Community speculation suggests Niantic might remove this option in future updates, making immediate action during the event the safest approach for collectors.

Action Checklist
- Complete 1-Star Shadow Raids to capture Shadow Koffing
- Collect 50 Koffing candies through catching, walking buddy, or rare candies
- Evaluate IV combinations for PvP vs PvE optimization
- Build complementary team members to cover Ground, Steel, and Psychic weaknesses
