Fire Emblem Heroes is getting some new characters direct from an upcoming Fire Emblem spin off. Tokyo Mirage Sessions #FE Encore is releasing for Switch on January 17, and four characters from it are joining the mobile game for a Paralogue story called "A Star Is Born."
Fire Emblem Heroes is gaining Eleonora and her Mirage Longbow, Kiria with her Mirage Rod, Mamori and her Mirage Axe, and Tsubasa and her Mirage Feather. All four characters are joining the game on January 19 at 11pm PT (January 20 at 7am UTC.) This means that players will have some time to meet them in the Switch game (which was originally released for the Wii U) before fighting with them in Heroes.
All four characters are able to summon spirits based on Fire Emblem characters in the original RPG--it plays more like Shin Megami Tensei than a classic Fire Emblem game.
Fire Emblem Heroes is one of many mobile titles Nintendo now has, including Animal Crossing Pocket Camp and Mario Kart Tour. The company has previously said that it is wary of how these games treat microtransactions.
