The Official Alola Region Collector's Edition Pokédex was released earlier this week, and the artwork for eight of the Ultra Beasts have made their way to various fan forums.

The new book, which is now available via major bookstores for a little more than $25, is filled with information on each Pokemon found in the Alolan Region of "Pokémon Sun & Moon." The book, which also serves as a postgame adventure guide, features illustrated art for the Ultra Beasts which Polygon described as "weird as heck." 

The illustrations of eight Ultra Beasts such as Guzzlord, Nihilego, Buzzwole, Pheromosa, Xurkitree, Celesteela, Kartana, and Necrozma are now widespread on various fan forums sites and online sharing communities such as Reddit and Imgur.

According to Polygon, Guzzlord is by far the creepiest of all the Pokemon as the concept art suggest that its arms come out of its mouth while the bug-like beefcake Buzzwole is kind of hilarious in the way he flexes and grabs other Pokemon.

Below are the photos uploaded on imgur:

Aside from extra details about the Ultra Beasts and their art illustrations, the book also includes a double-sided Pokédex poster on premium paper. There is also a section in the book featuring interviews with the game's director and producer.

To better guide you in playing the adventure game, the book also features data for all 301 Pokémon discovered in the Alola region and their different forms, as well as key information on each Pokémon's moves, Abilities, Stats, Evolutions, and how to obtain them. There are also lists of technical machines, items, and berries, including where you could find them.

For the competitive battler, the book also has reverse lookup tables for the moves and Abilities found in the Alola Region.
