For Pokémon the Movie Coco, a special 106/S-P Coco Movie promo will be given out if you visit theatres in Japan. The movie is scheduled to run in theatres on December 25, 2020. From the official page it mentions that this is a gift for a total of 3 million people attending theaters nationwide.
This card looks to be the a human on a Pokémon card that looks to be legal to play.
Some trivia: Tunu1223 spotted on the description of the card: ポケモンに育てられた人間 / Human Raised by Pokémon
Also a Pokémon the Movie Coco Illustration Contest has been announced. It seems like 55 people will be nominated. The 55 nominated people will get an exclusive movie themed paper playmat.
From the 55 nominated illustrations there will be 3 awards: "Director's Award", "Creatures Award" and "Parent and Child Award". These winning illustrations will get a Jumbo card with the award-winning illustrations + Pokemon Goodies. It looks like you will have to use the coloring sheet for this contest.
On the Application rules section it says: "Posting from overseas is possible, but prizes will only be shipped within Japan." Maybe you can submit internationally, but prizes will only be shipped in Japan. We can't fully confirm if you can submit your application if you are a non-Japanese citizen. You could always try it out.
