Ultra Beasts Leaked for Upcoming Expansions in Datamines

The latest Pokémon TCG Pocket expansion Celestial Guardians, is themed around the Pokemon in the Alolan region of Pokémon Sun and Moon. This focus is expected to continue into its upcoming mini sets, A3a (release date: May 29, 2025 at 6:00 AM UTC) and possibly A3b.

In the latest datamined files of current cards, each card is noted with a new description:

"IsUltraBeast": false,

This can only mean that Ultra Beasts will be introduced in some form into Pokémon TCG Pocket, continuing on with the focus of the current expansion.

Some Ultra Beasts have two types, which Pokémon TCG Pocket do not feature yet, so it is likely only some of them will be added to the game initially.

Like the Arceus Triumphant Light pack, there could be cards synergizing with Ultra Beasts in particular as well.

What are Ultra Beasts?

Ultra Beasts are extradimensional Pokémon, that come from other dimensions through Ultra Space. First introduced in Pokémon Sun and Moon, there are 11 in total with one of them being a Stage 1 evolution.

• Nihilego
• Buzzwole
• Pheromosa
• Xurkitree
• Celesteela
• Guzzlord
• Poipole
• Neganadel
• Stakataka
• Blacephalon

Nihilego

Nihilego is a Rock Poison type Pokémon with Pokédex description:

• 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.

Buzzwole

Buzzwole is a Bug Fighting type Pokémon with Pokédex description:

• 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.

Pheromosa

Pheromosa is a Bug Fighting type Pokémon with Pokédex description:

• 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.

Xurkitree

Xurkitree is a Electric type Pokémon with Pokédex description:

• 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.

Celesteela

Celesteela is a Steel Flying type Pokémon with Pokédex description:

• 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.

Kartana

Kartana is a Grass Steel type Pokémon with Pokédex description:

• 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.

Guzzlord

Nihilego is a Dark Dragon type Pokémon with Pokédex description:

• 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.

Poipole

Poipole is a Poison type Pokémon with Pokédex description:

• This Ultra Beast is well enough liked to be chosen as a first partner in its own world.
• An Ultra Beast that lives in a different world, it cackles wildly as it sprays its opponents with poison from the needles on its head.

Neganadel

Naganadel is a Poison Dragon type Pokémon with Pokédex description:

• It stores hundreds of liters of poisonous liquid inside its body. It is one of the organisms known as UBs.
• One kind of Ultra Beast, it fires a glowing, venomous liquid from its needles. This liquid is also immensely adhesive.

Stakataka

Stakataka is a Rock Steel type Pokémon with Pokédex description:

• It appeared from an Ultra Wormhole. Each one appears to be made up of many life-forms stacked one on top of each other.
• When stone walls started moving and attacking, the brute's true identity was this mysterious life-form, which brings to mind an Ultra Beast.

Blacephalon

Blacephalon is a Fire Ghost type Pokémon with Pokédex description:

• It slithers toward people. Then, without warning, it triggers the explosion of its own head. It's apparently one kind of Ultra Beast.
• A UB that appeared from an Ultra Wormhole, it causes explosions, then takes advantage of opponents' surprise to rob them of their vitality.
