How to get Magearna in Pokémon Legends: Z-A

Magearna, the mythical Pokémon, has been added to Pokémon Legends: Z-A with the Mega Dimension DLC, though you can’t catch it through regular means. Instead, it’s only obtainable through a side mission added in the DLC, but how you access that side mission isn’t entirely clear from the jump. You’ll have to have completed the base game’s main missions as well as a specific Mega Dimension side mission to unlock Side Mission 195 “Restarting Magearna” in the DLC.
