Shadow Regigigas

For much of Pokemon GO's history, the thought of a viable Normal attacker is blasphemous simply due to the massive damage gap between super effective and neutral moves - and this game has plenty of wonderful type specialists to shred every possible Raid boss. All this changed upon the release of Regigigas's extremely overpowered signature move, Crush Grip.

Wielding a monstrous attack stat and the sheer power of the Shadow boost, Regigigas's Crush Grip grants the progenitor of the legendary giants enough raw DPS to go toe to toe with some of the game's top type specialists. This can be pushed a step further with the appropriate Hidden Power type and Partly Cloudy weather. To give an example of this unhinged damage output, a Partly Cloudy Hidden Power Ground + Crush Grip Shadow Regigigas has greater DPS than Shadow Groudon against Electric-type bosses!

Even if you're lacking the appropriate Hidden Power type, a Zen Headbutt + Crush Grip Shadow Regigigas is still strong enough to act as a top counter to many Pokemon. Certain powerful type specialists - especially those featured during GO Fest and GO Tour, will still often be preferable to Shadow Regigigas.

Basically you're going to want a Shadow Regigigas. The real challenge is going to be collecting the appropriate Hidden Powers for a variety of raid bosses, but Crush Grip is so immensely strong that you often don't have to worry about that.

Best PvE Offensive Moveset

• Hidden Power is more useful than Zen Headbutt as long as a relevant typing can be obtained. Zen Headbutt, however, has a shorter duration, which can be more useful in Party Play.
• A notable mention goes to Hidden Power Rock, due to it also being boosted in Partly Cloudy.
• The Elite move Crush Grip is THE reason to run Regigigas. Its parameters surpass some of the game's most powerful Charged Attacks, allowing Regigigas to effectively bypass the type chart with raw power.
• Giga Impact is a great move, but it is far behind Crush Grip in performance.
• Focus Blast and Thunder are underwhelming.
