Why is it impossible to solo defeat Shadow Regigigas in Pokemon GO?

Here's why you cannot solo defeat Shadow Regigigas in Pokemon GO 5-star Shadow raids:

• As a mono-Normal-type, Shadow Regigigas has only one 160% weakness — Fighting.
• Regigigas hits super hard thanks to its base 287 Attack (+20% due to the Shadow Boost), so you will end up fainting a lot of times.
• The raid boss has a fairly high Defense stat, making it hard for even super-effective damage to leave a substantial mark.
• After Regigigas enters its enraged state, its Attack goes up by around 80% while its Defense is increased by 300%. As a solo trainer, you won't be able to subdue the raid boss at this point.

A look at Shadow Regigigas's stats and moves will help illustrate the reasons it is impossible to take it down as a solo raider:

• Combat Power: 44,972
• Attack: 287 (+20%) [This goes up by 85% when the raid boss is Enraged]
• Defense: 210 [This goes up 300% when the raid boss is Enraged]
• Stamina: 15,000 HP
• Fast Attacks: Hidden Power and Zen Headbutt
• Charged Attacks: Focus Blast, Giga Impact, and Thunder

Minimum number of raiders to defeat Shadow Regigigas

It will take at least two trainers using Level 50 Mega Lucario with Force Palm and Aura Sphere in Cloudy weather to take down Shadow Regigigas raids. The two players being in-game Best Friends and using Party Power will also help you maximize the damage output and reduce the time taken to defeat the raid boss.

Additionally, both trainers must use Purified Gems to subdue Shadow Regigigas when it gets enraged. You will also need a huge amount of Max Revives or Max Potions to recover from the incoming damage.

While it is not possible to solo defeat Shadow Regigigas in Pokemon GO, you can low-man these battles. If you can get at least three players to join, you will have a lot more options to counter Pokemon GO Shadow Regigigas raids.
