We've put together a solid guide on how to evolve Yanma into Yanmega in Pokemon Legends: Arceus.
Yanma, like many others, received its own secondary evolution with the release of Generation IV and the Sinnoh region. Given Pokemon Legends: Arceus is a revisit of the region from a previous point in time, it makes sense that those who debuted in the first round would make a reappearance here.
Below, we've explained everything trainers need to know about Yanma, it's evolved form Yanmega, and how to go about getting both.
How to Evolve Yanma into Yanmega
Yanma evolves into Yanmega once it knows the move Ancient Power.
This Pokemon learns Ancient Power at level 34 and masters it about 10 levels later at level 45. After this, trainers simply need to change Yanma's move set to include Ancient Power and adventure with it until it gains a level. The species should be eligible for evolution immediately afterward. If trainers manage to snatch a Yanma after this threshold, we recommend they check out its known moves as soon as possible.
Yanma can be found at the Gapejaw Bog, Ursa's Ring, and Droning Meadow in the Crimson Mirelands or at Heavensward Lookout in the Coronet Highlands.
Also known as the "Clear Wing" Pokemon, Yanma is clearly meant to resemble a dragonfly. Despite their apparent fragility, these wings can churn enough wind power to blow a house sky-high. Its Hisuian PokeDex number is #105.
Its evolved form, Yanmega, is known as the "Ogre Darner" Pokemon after the Green—or "ogre"—darner species of dragonfly. This species is "extremely violent" and wastes no energy when hunting, aiming for the prey's most vulnerable spots. Laventon remarks that any trainers "who manage to tame this Pokémon must be of incredible bravery." Its Hisuian PokeDex number is #106.
