I suddenly just felt compelled to rant about the Ultra Beasts looking weird, so enjoy:
There's a good reason so many people weren't convinced UB's were technically Pokemon about a year ago. I mean, just look at them. Maybe some of them aren't too different from the Pokemon universe's design philosophies, but they all have these certain, hard to describe with exactly the right words, unnerving qualities that make them feel like they don't belong. And the fact that, in spite of this, they're still there, mixing it up with comparatively silly designs, even making some of the legendaries look a little childish, it feels like a crossover with a brand that doesn't even exist. God they're so cool.

An eldritch clown that's exists in another dimension?

Fitting too. Considering the movie came out last week.
