Variant Pokémon are Pokémon who vary in their appearance compared to other Pokémon of the same species. This is often due to gender, special traits and Abilities, diet or environmental factors such as climate. Certain symbiotic relationships may also play a role in this.
While many variances are caused by natural processes, they sometimes can be artificially invoked as well. This may be achieved through the use of physical modifications or behavioral conditioning, or contact with certain items and radiation.

Cloned Pokémon are Pokémon that have been artificially duplicated from another specimen. This process works on both living and fossilized specimens.

Other known cloned Pokémon are Psyduck, Seadra, Tentacruel, Pidgeot, Scyther, Hitmonlee, Dewgong, Sandslash, Vaporeon, Golduck, Nidoqueen, Ninetales, Vulpix, Vileplume, Wigglytuff, Rapidash, and Rhyhorn.

The Generation I Pokédex entries for Arbok state that there are six variations of its face-like hood markings that differ between areas. Eight designs are known, but only four have appeared in the games, and only three of which appeared in main series games. In Pokémon Adventures, Arbok gains a special ability depending on its pattern.
The most common hood pattern has red, teardrop-shaped eyes outlined in black with yellow, elongated hearts inside, a black mouth, and a black arrow over the eyes, with two red dots near the tip and an upward-extending tail. This design appeared in the Generation I games and all games from Pokémon FireRed and LeafGreen on, the anime, the manga (except Agatha's Arbok in Pokémon Adventures), most TCG art, the FireRed and LeafGreen Ken Sugimori art, Dream World art, and anime art. In the Pokémon Adventures manga, this is the "regenerative pattern" and is present on Koga's Arbok. These Arbok have a forked tongue and many fangs.
Arbok also has several hood variations with round eyes and a red mouth outlined in black. The most common variation of this has two black fangs descending onto its mouth, black eyebrows, and outward-pointing eyelashes. This design first appeared in the official Pokémon Red and Green Ken Sugimori artwork, and has also appeared in the Ruby, Sapphire, and Emerald sprites, the TCG cards Arbok from Fossil, Arbok from Expedition, and Janine's Arbok from the VS set. These Arbok have a pointed tongue and four fangs.
Another hood variation with round eyes appeared in Gold, Silver, and Crystal. This pattern has no fangs or eyebrows, and its eyelashes point upward. It has also appeared in Pokémon Pinball and on the Arbok Coin in Pokémon Card GB2: Here Comes Team GR!. These Arbok have a forked tongue and four fangs.
The final round-eye variation only appeared in Pokémon Ranger. This design has no eyelashes or fangs. A Y-shaped mark branches over each eye and connects to the middle to the mouth. The branches each have smaller, Y-shaped ends, between each of which resides a small black dot.
Arbok's conceptual art had three other hood designs, but these were only used in the Pokémon Adventures manga, in which Agatha's Arbok can change its markings to alter its powers. These are the speed, attack, and invulnerability patterns.
An evil-looking pattern was created by Mitsuhiro Arita solely for the TCG. Each red eye has a black mark in the center and flared outsides, and shares a combined yellow border. Its mouth represents a grin with eleven pointed, red teeth outlined in black. It is featured in the card Dark Arbok from the Team Rocket set.
- Main article: Pikachu variants
Almost every Pokémon medium has featured a different Pikachu variant, most notably Surfing and Flying Pikachu.
Several of Vulpix's Pokédex entries mention that the species only has one, white-colored tail when they are born. The tail would then split into six orange-colored tails as it matures, and eventually splits from their tips to increase in number even more.

Shellder can be either a bivalve shell or a spiral-shaped shell, depending on whether or not it is attached to a Slowpoke. Though impossible in the games, multiple Pokédex entries state that a Shellder can be detached from the Slowbro (making it devolve into a Slowpoke) or Slowking (making it lose its memory) it is attached to. This gives them a few more characteristics of Shellder variants than actual evolutions. However, because the Shellder is attached to and evolves with the Slowpoke, after evolution they are treated as one Pokémon. Slowbro's conceptual art depicted other variations, but they were never seen anywhere else.
Exeggcute and Exeggutor
Exeggcute are not always seen as a group of six; the number of heads an Exeggutor has also varies. Exeggutor's Pokédex entries state that, living in a good environment, more heads will grow in addition to the three it is usually seen with. Eventually, one of the heads will fall off and become a sole Exeggcute. This Exeggcute will telepathically communicate with others, in order to join and form a cluster of six. Until they are gathered, Exeggcute won't be able to maintain balance.
Kangaskhan's category in Japanese is "Parent and Child Pokémon", implying it consists of two beings. This is ratified by the fact that they are all born with a child in their pouch. The child is purple, and has not yet developed most of the features from its parent, having to stay in the pouch for 3 years. Although Kangaskhan's moves are performed by the parent, some TCG cards (Jungle Kangaskhan, Blaine's Kangaskhan, Aquapolis Kangaskhan, and EX FireRed & LeafGreen Kangaskhan) have attacks that involve or are performed by the child.
When Kangaskhan Mega Evolves into Mega Kangaskhan, the baby emerges from the mother's pouch and is noticeably matured.
Ditto is known for its ability to transform into an exact replica of any other Pokémon. However, some Ditto are incapable of changing the face by memory, with the result being a deformed copy of the target Pokémon with a blank, beady-eyed expression.
This appearance was first present in one of Duplica's Ditto, both in the anime and in the Electric Tale of Pikachu manga. It was later seen in Ditto cards from the EX Delta Species expansion of the TCG, in a kind of Clefairy that appears in the Veilstone Game Corner, in Pokémon Snap with three Ditto disguised as Bulbasaur, and in the Special Episode Here Comes Team Charm!.
Like Unown, Spinda has many visual variations in its species, all involving the placement of its spots. Like Unown's letter, the spot placement is generated based on the individual's personality value, and likewise, has no effect on the Pokémon's stats. Unlike Unown, however, these differences are rarely repeated, as the calculation uses the entirety of the personality value—a number that can range from zero to 4,294,967,295 (232 - 1). Some personality values can, however, produce the same apparent pattern from differing values.
A purple Kecleon is one of the two Kecleon Brothers in the Pokémon Mystery Dungeon series. He also appeared in the special episodes Pokémon Mystery Dungeon: Team Go-Getters out of the Gate! and Pokémon Mystery Dungeon: Explorers of Time & Darkness.
Some variants have only been mentioned in Pokédex entries; Pokémon of these variants have not been shown in any Pokémon media.
- The Diamond, Pearl, and Platinum Pokédex entries for Weezing state that triplets of the species have been discovered. All Weezing have a third gas chamber, though it has no face.
- Mantyke's Pokédex entry in Pearl says that the pattern on its back varies from region to region. While there is no difference between the Sinnoh and Johto games (due to using the same sprites), the "face" in the Unova and Kalos games appears wider. However, all Mantyke within a Generation V or VI game will look the same, regardless of origin.

In Pokkén Tournament, Shadow Mewtwo is a Mewtwo that had unwillingly merged with and become possessed by a Shadow Synergy Stone, causing its appearance to change. When Anne wields the power of the Synergy Stone contained in her brooch, Mewtwo is separated from the Shadow Synergy Stone and its appearance returns to normal.
In All That Glitters is Not Golden!, a Trainer named Keenan owned a Sudowoodo that he had turned to gold during a science experiment, in an attempt to make Sudowoodo immune to Water-type attacks. The changes made to Sudowoodo were eventually reversed.

As Primal Dialga, it is incapable of logical reasoning or showing mercy, only seeking self-preservation and preventing time from flowing properly.

In The Ghost of Maiden's Peak, a Gastly, who had the ability to create illusions that were tangible enough to attack people, created a fusion of Venusaur and Blastoise to scare Bulbasaur and Squirtle, calling it a "Venustoise" (Japanese: フシギックス Fushigix).
