If you’re looking to evolve Gastly and Haunter into Gengar in Pokemon Legends: Arceus, there are two ways to go about it.

Back in Gen 1, Gengar was one of the most powerful Pokemon in the Kanto region. Now, even after 8 generations of Pokemon, the Ghost-Type is still proving to be one of the most popular choices for a trainer’s team.

Even Ash has a Gengar in the latest Pokemon series, and the powerful ‘mon was one of the few to receive its own Mega Evolution too.

Interestingly, it seems that Mega Evolution is in the Pokemon Legends files, suggesting that the feature could soon arrive. So why not get your hands on a Gengar just in case it does?

You’ll also need to catch every Pokemon in the game to find Arceus, it’s worth noting.

But that probably doesn’t include the 158 Pokemon supposedly coming as Pokemon Legends DLC.
