Gigantamax Gengar

The Great Ghost rises once again! Gigantamax Gengar is a monstrous Dynamax option, dealing huge Ghost Type damage thanks to Max Phantasm's boosted Max Move power. It's also in a fairly safe position long-term, as it has the second highest Attack stat of any Gigantamax Pokemon, falling behind only Gigantamax Inteleon by one point. It also has very limited direct competition that's likely to show up in the future, so this is definitely a safe investment.

Due to its frailty, Gigantamax Gengar can rely heavily on its tanky teammates and partners to stick around. Its pronounced weaknesses to Ghost and Psychic, the two types that it wants to counter the most, can shorten its Gigantamax rampage if not played carefully. Making proper use of switches to catch charge moves is essential to maximizing this Pokemon's immense damage potential. Still, this gateway to the next world is definitely worthy of a slot on your team! Heck, if you're lucky enough to score a really good one from Gigantamax Raids, it can even pull double-duty as a Mega Gengar. Just keep in mind that you can't use it in Max Raids while Mega Evolved....

Shadow Claw is by far Gigantamax Gengar's Fast Attack of choice, boasting STAB, high power, and most importantly, a 0.5 second duration.

In PvP, Gigantamax Gengar is effectively no different from a normal Gengar, except without access to Return as a move option.
