Ultra Beast

The Ultra Beasts (Japanese: ウルトラビースト Ultra Beast), also abbreviated as UBs (Japanese: ＵＢ UB), are a group of who have gone through Ultra Space. Most of them were introduced in Pokémon Sun and Moon, though some were introduced in Pokémon Ultra Sun and Ultra Moon.
Ultra Beasts infrequently appear from Ultra Wormholes in Alola. These appearances are apparently as unexpected for the Ultra Beasts as it is for Alolans, which tends to make them combative. They are especially drawn to people who have passed through an Ultra Wormhole due to the Z-Power energy left on them, apparently expecting to find another wormhole they can use to return home.
There are 11 Ultra Beasts in total. All Ultra Beasts share common attributes with one another, such as possessing the Ability . When an Ultra Beast is encountered in the , the Z-Power energy from Ultra Wormholes manifest as a red aura that boosts one of its stats at the start of , similar to a Totem Pokémon's orange aura. Wicke theorizes that they store this energy in their bodies.Wicke, : "There are also Pokémon on our planet that possess this same kind of energy. I think you know what I mean. The so-called Totem Pokémon that you faced in your trials." All Ultra Beasts as well as , , and the light trio all share a unique sound frequency found in their cries, approximately 1.25 seconds in duration.
All Poké Balls (except for the Master Ball, which can catch any Pokémon without fail) have difficulty recognizing Ultra Beasts as Pokémon due to their extradimensional origins, and thus have a catch rate modifier of 410/4096× (~0.1×) when used on them, impairing their ability to effectively catch them. To circumvent this, the Aether Foundation's Faba had created Beast Balls, Poké Balls specifically designed to catch Ultra Beasts, having a catch rate modifier of 5× when used on them, though they have a modifier of 410/4096× (~0.1×) on Pokémon that are not Ultra Beasts.
==Concept and development==
Ultra Beasts are based on the idea of , as stated by Shigeru Ohmori in an interview in Pokémon Sun & Pokémon Moon: The Official Alola Region Pokédex & Postgame Adventure Guide.Interview with Game Freak in Pokémon Sun & Pokémon Moon: The Official Alola Region Pokédex & Postgame Adventure Guide, pp. vi-vii: Ohmori: "...When I read about [invasive species], I wondered if we couldn't express invasive species in the Pokémon world as well, and the idea we came up with was the Ultra Beasts..." Ken Sugimori had advised that each Ultra Beast design incorporate contradictory elements, along with concepts that are typically avoided when creating new Pokémon to differentiate them from other Pokémon.An Exclusive Interview with the makers of Pokémon Ultra Sun and Pokémon Ultra Moon! | Pokemon.com, archived March 3rd, 2018
==List of Ultra Beasts==
In , the is requested to obtain and catch all Ultra Beasts who have been spotted in Alola. Looker of the International Police and Wicke of the Aether Foundation will both provide the player with information on the Pokémon both during and after their mission with an Ultra Beast. Looker will also provide information based on through the player's Pokédex after they have caught it.
 	Ultra Beast 	 	Code name 	 	Description
Introduced in	Introduced in	Introduced in	Introduced in 	Introduced in 	Introduced in
#0793 	 	 	UB-01 Symbiont 	Ultra Deep Sea 	
* UB-01. Code name: “Symbiont.” Properly known as Nihilego. There have been sightings reported of this beast in Alola’s past. Its most distinctive feature is its parasitic capability. When Nihilego latches on to a host, it does not manipulate its actions directly. Rather it awakens the host’s own capabilities and boosts them to an extreme extent in order to protect itself.
* It injects the host with a sort of neurotoxin to achieve this effect. This neurotoxin of Nihilego’s is incredibly stimulating and inspires feelings of extreme excitement and a lack of inhibition in its host. In other words, anything or anyone that Nihilego latches on to will have its native skills forcibly activated to their fullest extent and will then act as it naturally desires to.
#0794 	 	 	UB-02 Absorption	Ultra Jungle 	
* UB-02. Code name: “Absorption.” Properly known as Buzzwole. This UB was sighted for the first time following the incidents at Aether Foundation. Its most distinctive feature is its skill to strengthen itself. Buzzwole is able to absorb energy and then achieve a chemical reaction between the energy it has absorbed and its own body fluids.
* As a result, Buzzwole’s body swells to an almost explosive extent. Its muscles bulge and are so thick and dense that they are stronger even than steel. Both its Attack and Defense experience a clear leap in power. It also displays a habit of striking a pose each time that it takes any sort of action... It is thought this might serve as a method of communication, but it is not well understood.
#0795 	 	 	UB-02 Beauty 	Ultra Desert 	
* UB-02. Code name: “Beauty.” Properly known as Pheromosa. This UB was sighted for the first time following the incidents at Aether Foundation. This UB can reach speeds exceeding 120 mph in just an instant. This speed is greater than any other living creature that has been discovered to date. But its most distinctive features may in fact be its beauty and its powerful pheromones.
* Most any creature that squares off against Pheromosa becomes confused, as if struck by the beast’s beauty, and loses the will to fight. It is still a subject of research, but it’s thought that Pheromosa may possess some sort of organ able to produce a pheromonal substance previously unknown to science.
#0796 	 	 	UB-03 Lighting 	Ultra Plant 	
* UB-03. Code name: “Lighting.” Properly known as Xurkitree. This UB was sighted for the first time following the incidents at Aether Foundation. Its most distinctive feature is an organ that can generate power. This UB’s bodily makeup is highly reminiscent of electric wiring, thus enabling it to conduct electricity with great efficiency.
* It can discharge as much as a million volts of power at a time. When it begins to run out of power, it stabs its legs and tail into the soil, entering a treelike state as it absorbs electricity from the ground.
#0797 	 	 	UB-04 Blaster 	Ultra Crater 	
* UB-04. Code name: “Blaster.” Properly known as Celesteela. This UB was sighted for the first time following the incidents at Aether Foundation. Its most distinctive feature is the energy that it stores within itself, a flammable gas that it can shoot from its two huge arms.
* This is mostly used to propel itself in flight and for battle, but it is thought to have sufficient power and lift to even fly into space. Its bodily construction closely resembles that of a plant, and it absorbs nutrients from the soil.
#0798 	 	 	UB-04 Blade 	Ultra Forest 	
* UB-04. Code name: “Blade.” Properly known as Kartana. This UB was sighted for the first time following the incidents at Aether Foundation. Its most distinctive feature is its thin and razor-sharp body, of which every edge has as cruel a cutting edge as any well-honed blade. The edges on its arms are particularly in a class of their own.
* Any opponent who tries to attack it will be cut down with a single strike of its “blades.” Its thin body also allows it to evade attacks by dancing lightly out of the way. This is a very dangerous creature, considering its excellent offensive and defensive capabilities, but due to the nature of its body, it is also highly vulnerable to fire and moisture.
#0799 	 	 	UB-05 Glutton 	Ultra Ruin(core series)Unknown() 	
* UB-05. Code name: “Glutton.” Properly known as Guzzlord. This UB has been sighted in the Alola region in the past as well, according to our reports. It seems it was targeted by the International Police in a top-secret mission at that time. Its most distinctive feature is its limitless appetite. It feeds without pause every moment that it is awake.
* It uses the two large tongues that protrude from its mouth to catch and devour everything in its path, be it organic or inorganic matter. And while it eats such an inordinate amount, Guzzlord excreta has never been discovered. It is thought that it might fully convert the things that it eats into energy for it to use.

The first recorded sightings of Ultra Beasts were documented a few years before the events Pokémon Sun, Moon, Ultra Sun, and Ultra Moon during researches done by the Aether Foundation in the Lab area of Aether Paradise in the center of the Alola region. Professor Mohn discovered and proved the existence of Ultra Wormholes, the realm beyond them: Ultra Space, and even life living there: Ultra Beasts, the first one discovered being the UB-01 Symbiont Nihilego.

Upon accepting, the player begins a series of missions to capture the Ultra Beasts, spanning all four of Alola's islands, each time based out of the island's motel (or the restaurant on Poni Island). In some missions, there are multiple of the same species of Ultra Beast to be captured, and in some missions they may be found at either of two locations. If the player flees from or defeats an Ultra Beast, it remains in the area and the player will still be able to find it again immediately (either at the same place or at the alternate location, if applicable).
