This month's issue of CoroCoro Comic will feature the new Pokémon マギアナ Magiana. A silhouette of the new Pokémon is featured on cover.
Nothing is known about this Pokémon at this time, other than that the magazine explicitly calls it a new Pokémon. This month's CoroCoro Comic is set to be officially released on Feb. 15, although fans often obtain the magazine earlier.
The cover was revealed in an official promotional video for this month's issue of CoroCoro Comic.
