There are lots of Pokemon released each generation and, unfortunately, they can't all be winners. Some of the dumb new Pokemon in Sun and Moon definitely prove that this is still very much true. While the games both feature strong lineups of Pokemon, they also have some new ones like Type: Null, Alola Dugtrio, and Incineroar that can all compete for the title of worst Sun and Moon Pokemon.
Alola Dugtrio looks like somebody on the Pokemon design team saw a silly meme or some mashup fan art and said, "Screw it, why not?"
So this is what a Garfield/Pokemon crossover looks like. Honestly, this little fellow is pretty cute, especially if you have an affinity for house cats. That's part of the problem, though. The resemblance to your neighbor's tabby is a little too pronounced.
Gumshoos looks like Donald Trump at the end of No Shave November. There, have fun unseeing that.
The corpulent frame and eyes full of hate make him look like an elementary school class's pet hamster - that's not a good look for a Pokemon. Raticate is not a creature to which future Pokemon designers should aspire.
