Deoxys is an alien-like bipedal Pokémon that has four Formes, each focused on a different stat. The main components that are constant for all four Formes are a dominant reddish orange color, a bluish-green face, and three bluish-green dots on its back arranged in a triangle. Typically, there is a purple stripe running down the center of its face and a purple, crystalline organ in its chest. Its white, circular eyes are set inside rectangular, black eye sockets. It is shown in the anime, that Deoxys may have a green crystalline organ and facial stripe.
In its Normal Forme, Deoxys has tapering legs with a segmented, vertical, blue stripe on the upper portion. The abdomen is black with vertical lines, while the majority of its skin is reddish-orange. The arms are capable of taking different forms, usually a pair of tentacles coiled in a double helix. One tentacle is the primarily skin color, while the other is light blue. Alternately, it can form more humanoid arms with a red top and blue underside and a five-fingered hand. This Forme has a blunt protrusion with a single blue stripe on either side of its head and stubby tail.
While in its Attack Forme, its legs remain tapered. However, its blue stripes are no longer segmented and run the entire length of the leg and there is now a large spike on the knee. Two pairs of whip-like tentacles with pointed tips, one reddish-orange and one blue, replace its previous coiled, blunted tentacles. The protrusions on its head are now triangular with an additional one extending from the top of its head. Most of its reddish-orange skin has receded, revealing a striated, black chest and abdomen. Finally, its tail is now longer and more pointed.
Deoxys's Defense Forme has bulky, wide legs that are somewhat flat at the end with a bluish-green spot on each knee. It retains its two pairs of red and blue tentacles, but they are now flat and broad. The head has fused with its body and all protrusions are gone, causing it to resemble a helmet. The reddish-orange skin now covers the entire body, so none of its inner black portion is visible. There is now a single blue stripe on each shoulder, and its tail has disappeared.
The Speed Forme of this Pokémon has a sleek black body with thin striation. The reddish-orange skin now covers only its head, hip joints, and the area around its crystal. There is now only one tentacle on each side of its body, one red and one blue. The protrusions on its head now point upward and the back of its head now forms a long spike. There is a long, thick blue stripe running down the center of this longer protrusion. More blue stripes appear on either hip joint and on its legs.
Deoxys was formed by the mutation of a virus from space. The Pokémon is highly intelligent; its brain appears to be the crystal in its chest. This organ is capable of firing laser beams. Additionally, Deoxys can use psychokinetic powers, which are useful for its signature movePsycho Boost. As shown in the anime, it is able to regenerate any part of its body that it may have lost during a battle. It has also demonstrated the ability to create an aurora without changing its Forme. These auroras can have different electromagnetic wavelengths and are used to communicate with other Deoxys. It is also shown that the various electromagnetic waves given off by people, Pokémon, and all electronics can obscure its vision if there is enough interference with its communication. This Pokémon came from outer space from inside of a meteor.
In the anime and manga, Deoxys has been observed to create clones of itself. These clones have lifeless eyes and duller color, lack of the trademark crystal on the chest, and seem to be unable to change from the Normal Forme. Furthermore, they seem unable to morph their tentacles into hands. When these clones are defeated, they dissolve into dust-like particles.
Deoxys debuted in Destiny Deoxys. Two fell to earth in a meteorite; one had a green crystalline organ, and the other had the standard purple one. When the Deoxys with the green crystal (which spent most of its time as a crystal in the movie) was taken to LaRousse City, the purple crystal Deoxys followed behind and began a search for it. However, it ended up in an epic battle with Rayquaza, which thought Deoxys had invaded its territory. As Pokémon Emerald had not been released when the movie was produced, only its Defense, Normal, and Attack Formes appeared.
A Deoxys appeared in Cheers on Castaways Isle! in all of its Formes. It crash-landed as a meteor on a deserted island in the middle of Diablo's Ocean, shattering upon impact and leaving only its crystal. As a result, the local Water-type Pokémon worked together to gather meteor fragments to help restore it. This eventually worked after receiving help from Pikachu and Piplup.
A Deoxys appeared in PK21, where it saved Pikachu, Piplup, and a wildSkitty when they all fell from a stone staircase.
Two Deoxys made a cameo appearance in the opening sequence of The Rise of Darkrai, where they were soaring across the sky in their Normal Formes.
Deoxys plays a large part in a special chapter of volume 3 in Pokémon Diamond and Pearl Adventure!. Hareta and Mitsumi come upon a large meteorite in Veilstone City. Mitsumi proceeds to tell him that there is a Pokémon that comes from a meteorite. He tells her that he's met Deoxys. She freaks out and doesn't believe him, so he tells the story of how he met Deoxys. Hareta is seen jumping around the forest until he starts riding a Drifloon. A Murkrow flies toward them and pecks the Drifloon, causing it to explode. Hareta is seen plummeting to the ground, and then bouncing off a Bibarel's stomach. He lays down on the ground with the Bibarel as a pillow, when the Bibarel starts getting worried, because it sees the meteorite containing Deoxys zooming to the ground. The Bibarel tries to tell Hareta what's happening, and he looks up and wonders what it is. The Pokémon and Hareta try to get away as the meteorite crashes down. Deoxys emerges from the meteor, and Hareta thinks it might be a Pokémon. Meanwhile, Mars and some grunts see the crash, and begin to battle it, but to no avail.
Professor Rowan shows up, a little worried that something might have happened to Hareta. He asks Rowan what happened to "that weird Pokémon". They then see Deoxys, and Rowan is shocked to see such a rare Pokémon. It transforms to Attack Forme and fires off a Psycho Boost at Hareta and Rowan. Rowan tells Hareta not to make it any angrier, but instead he jumps on top of Deoxys and asks what's wrong. It flings him off, then tries to fire another Psycho Boost at him, but he jumps around it, evading it completely. He jumps on it again, but it transforms to Speed Forme while he is still on it. It starts flying around the forest with Hareta, while he asks Deoxys what's wrong once more. It tells him what's wrong, but it throws him off itself. Then he battles Deoxys with his friends from the forest. Onix tries to Headbutt it, but it misses. It transforms to Defense Forme, and then Hareta jumps on Deoxys and covers its eyes. Then he tells a bunch of Kricketune to have a "super bug concert". Rowan compliments him on the super-effectiveness of the attack, then it transforms back to Normal Forme. It becomes calmer, but transforms to Attack Forme and fires off another Psycho Boost, this time hitting a Drifloon. It explodes, defeating Deoxys. Deoxys is totally calm now, and it merges its tentacles to create a hand, and it shakes hands with Hareta. Hareta finishes telling the story to Mitsumi, and tells her that it wanted to find out more about this planet.
A Deoxys made it debut in A Visitor From Outer Space?! where it was first mentioned by Professor Oak while having Red obtain an orb that contains it. As Red got the orb, he competed with a guy and his Swampert in which Swampert's owner ended up swiping the orb for a Voltorb. Deoxys appeared in Clefairy's flashback in the same chapter where it was fighting the Swampert.
An Attack Forme Deoxys will sometimes be released from a Poké Ball. It floats towards the top of the screen and does a spin. It will then shoot a powerful Hyper Beam, drawing in all the opponents near it and sending them flying. Coming in contact with Deoxys's body will do damage.
A DNA Pokémon born through the mutation of the DNA of a space virus. It has multiple Formes, and the abilities it possesses and the techniques it can remember change from forme to forme. It has four forms: normal, attack, defense, and speed. It can be made to change forms by using the power of a meteorite in Veilstone City.
Deoxys appears as a Poké Ball summon in the 3DS and Wii U versions of the game, its behavior unchanged from Brawl.
NA:This Psychic-type Pokémon was born from a virus attached to a meteorite. It has four different Formes, but in Smash Bros. only the Attack Forme appears. In battle, it'll soar skyward before unleashing a powerful Hyper Beam attack straight downward from the crystal in its chest.
PAL:Deoxys was formed from a mutated virus that came to Earth on a meteorite. It comes in four different Formes, but in this game, it appears in Attack Forme. When summoned, it heads skywards before firing its Hyper Beam attack straight downwards from the crystal in its chest.
Deoxys is also one of two Pokémon that has defenses over 100 at Level 100 if not given any vitamins or Gummis, the other being Lugia.
In Pokémon Ranger, Deoxys's Forme changes every time its Browser entry is accessed. It cycles in order from Normal Forme to Attack Forme to Defense Forme to Speed Forme and finally back to Normal Forme.
In the anime and Pokémon Ranger, Deoxys is able to change to any of its forms at will regardless of where it is. While it can willingly change in the Pokémon Adventures manga, its choices are limited by the environment.
Due to the cause of Forme change in Generation III being the game Deoxys is in, only Speed Forme Deoxys is banned from the Battle Frontier, as only Speed Forme Deoxys is obtainable in Emerald.
In the games, the Sevii Islands and Orre* are the only regions where all four Formes have not been available.
Deoxys was the first Pokémon to have its own unique battle music.
Using the first letter from the names of three of Deoxys's Formes, one can spell "DNA" (Defense, Normal, Attack). The letter "s" at the ending of Deoxys's name could stand for Speed.
Before Generation V, Deoxys was the only Pokémon whose stats were recalculated (to apply gained effort points to its stats) immediately after a battle. Other Pokémon had to level up, use the box trick, or be fed a vitamin or stat-reducing Berry in order to have the effort values applied to their stats.
When in the wild, or while looking at a Deoxys belonging to another player (e.g. while trading), it will appear in its Normal Forme in Generation III.
Contrary to its classification in Pokémon Omega Ruby and Alpha Sapphire, PokémonCenter.com and a Scholastic book on Legendary and Mythical Pokémon call Deoxys a Legendary Pokémon rather than a Mythical Pokémon.
Deoxys' encounter level of 80 is the highest of any scripted wild Pokémon. The only other encounter with a level as high was Arceus in the Hall of Origin (albeit not legitimately obtainable).
Deoxys appears to draw inspiration from certain representations of aliens and visual representations of the DNA double helix. It may also be more loosely based on viruses and mutation. It also strongly resembles the shape of a chromosome, or a package containing much of the DNA of an organism. This makes sense due to its ability to duplicate, just like a chromosome does during cell division.
Deoxys is an abbreviation of deoxyribonucleic acid—or DNA—the medium of genetic code in many cellular organisms.
