Metagross is a Psychic/Steel type pokemon, the evolved form of Beldum & is one of the two pseudo legendaries that can be found in Hoenn. Metagross makes yet another design, where it looks cool, but just doesn't really appeal to what I tend to enjoy with designs. Other than that though, Metagross is really good with battling as of course it has really great stats & abilities, as well, it doesn't have that bad of a movepool either (with it being a pseudo legendary though of course it's gonna have great battling capabilities lol) Overall, I really love Metagross, and it really wasn't an easy decision choosing who to give 20th, but the non-appealing design is what made me choose to rank Metagross at this spot.
Coming in at #20 on my ranking is:
