"The bear is called Kiteruguma and is Normal/Fighting with the abilities Fluffy and Klutz, while the ghost is Mimikkyu and is Ghost/Fairy. It has the ability called Disguise.
People in Alola are scared of Kiteruguma to the point of having warning signs about it. It is really strong and can break anytthing in two. It likes to hug its trainers but is strong. Raising one puts your life in danger.
Mimikkyu hates sunlight, preferring dark places. It is rumoured that the cloth covering its body is a strategy to avoid the sun. Don't try to remove the cloth it is said that those that do become afflicted with an illness. Mimikkyu's costume is based on Pikachu merch that was popular 20 years ago. It wants to be loved by people like Pikachu is. We'll bring more as it comes"
Yet another Bear Pokemon, though I think it's type combination of Normal/Fighting is new atleast. The Pikachu wannabe I know for sure is a new type combo and a great one too! I also like it's theme, essentially hiding under a paperbag. I wonder if it evolves if we'll see it come out of it's shell. Anyway I like these new Pokes, keep em coming!
Also here's a new trailer showing some new stuff but not in detail.
