Introduction to Shadow Regigigas in Pokémon GO
In October 2023, Shadow Regigigas made its debut in Pokémon GO as part of the Team GO Rocket Takeover event, coinciding with the Adventures Abound season. This powerful Pokémon will be featured for the first time in 5-star raids during the upcoming Shadow Raid Day event, scheduled for May 17, 2025, from 2 PM to 5 PM local time.
This article lays out the various ways to encounter Shadow Regigigas in Pokémon GO and what you need to know to maximize your chances.
Ways to Obtain Shadow Regigigas in Pokémon GO
Players can acquire Shadow Regigigas through two primary methods:
- Rescue from Giovanni
- Participate in 5-star Shadow Raids
1. Rescue from Giovanni
Initially, Shadow Regigigas could only be obtained by rescuing it from Giovanni. Although the classic Super Rocket Radar mechanism no longer grants a chance to face Giovanni—who currently has Shadow Dialga as his main Pokémon—trainers who completed the Pokémon GO Tour: Sinnoh – Global Special Research still have the opportunity to encounter Shadow Regigigas.
When captured from Giovanni, Shadow Regigigas will present a maximum Combat Power (CP) of 979 without any weather-related boosts, and it can reach 1,614 CP if encountered during Partly Cloudy conditions.
2. 5-Star Shadow Raids
The most consistent method to catch Shadow Regigigas is by participating in the 5-star raids set to occur precisely on May 17, 2025, between 2 PM and 5 PM local time. Due to its strength, solo players may find it impossible to defeat Shadow Regigigas alone. Teaming up with fellow trainers is highly recommended to ensure success. Here are the expected CP ranges based on weather conditions:
- No weather boost: CP ranging from 2,315 to 2,483 at level 20 (IVs from 10/10/10 to 15/15/15).
- Weather-boosted (Partly Cloudy): CP from 2,894 to 3,104 at level 25 (IVs from 10/10/10 to 15/15/15).
