Palkia is a light-purple, theropod-like Pokémon with stripes and markings of a darker shade and gray underarms and waist. It has round purple-striped plates on its shoulder area, where two pink pearl-like crystals lie encrusted with a gray rim encircling them, and fin-like wings on its back. Palkia's arms have extended formations resembling gauntlets and a purple band around each wrist. Palkia has a long neck that is normally bent, a pointed white crest on the top of its head that extends to its wings, two strong horn-like tusks on the sides of its jaw, and a powerful tail. It has faint cracks along its legs and tail. As seen in Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness, Palkia is capable of travelling by creating a large yellow sphere from its two pearls, then using it to fly very fast.
In its Origin Forme, which is said to be its true form, Palkia's appearance changes drastically from its other theropod-like Forme, taking on a centaur-dragon hybrid look while resembling its creator, Arceus. The main body becomes larger and grayish pink, with light gray accents on the tips of its wings and legs, along with various dark purple accents. Its shoulder plates are larger and seem to be made of the same pearl-like crystals as the ones embedded at the center, with six rectangular dark purple protrusions surrounding them. Its lower half becomes bigger and resembles that of a horse. Palkia's arms become its forelegs, with hooves, protrusions on the knees, and rectangular spikes on its upper forelegs akin to its other Forme's arms. The back legs gain hooves as well, with heels on the back of the foot, and they are bent in such a way that allows Palkia to stand up on its two back legs. The tail becomes shorter and splits into five. On the center of Palkia's abdomen is a structure consisting of two dark purple circular shapes connected to two circles of the same color, resembling Arceus's cross-like wheel. Palkia's neck and markings on its lower body become shorter. The pointed crest on its neck becomes taller and longer. Its lower jaw gets a plate-like mask covering it, with multiple spikes all over it: one at the front, a pair extending towards the bottom of the jaw, and two pairs on either side extending towards the back. The plate-like mask can be lowered to reveal its mouth when roaring or using attacks. It is believed that Palkia's Origin Forme resembles Arceus as a strategy in order to gain its power. Palkia's transformation into its Origin Forme can be triggered using the Lustrous Globe.
Palkia has the power over space: it can warp space, travel to faraway places or other dimensions, connect dimensions through dimensional portals as seen in the anime (along with undoing their effects), and destroy space itself. It was said that Palkia can create alternate realities as well. The space Palkia controls is said to become more stable with its every breath. In its Origin Forme, Palkia can walk on all fours and fly, and unleash meteors and shockwaves. The crystals and purple accents on Palkia's body glow brightly when it uses its powers.
Palkia has the power to create a new universe by itself or with Dialga. Palkia lives in a spatial dimension, making its behavior nearly impossible to study. The dimension Origin Forme Palkia lives in is said to be in shreds like ribbons; however, it is known to be very protective of its home. Palkia has been seen in violent conflicts with its counterpart Dialga.
Palkia is the only known Pokémon capable of learning the move Spacial Rend. Palkia can use Spacial Rend to tear both its opponent and the space around them apart at the same time, warping everything it hits. The move can also be charged into a more powerful version while the Pokémon is in its Origin Forme, as shown in the boss battle in Pokémon Legends: Arceus.
In The Battle Finale of Legend!, Palkia and Dialga were summoned by Cyrus on the Spear Pillar. They were put under his control through the use of the Red Chain and were tasked by him to open a portal to another dimension, wanting a world of his own. After the Red Chain's destruction and Cyrus's exit, Palkia and Dialga rampaged, creating a danger for Sinnoh. However, the two were calmed down and sent away with the help of the lake guardians.
Palkia, the Spatial Pokémon. A Water and Dragon type. Palkia is said to live in the space between parallel worlds, and with its ability to open portals at will, one can travel to faraway places and dimensions.
In The New World, Palkia and Dialga were captured at Spear Pillar by Cyrus, who intended to use them to destroy the world and create a new one. Along with Dialga, it was freed by Giratina before they could help Cyrus succeed in his goal.
A Palkia briefly appeared as a silhouette in GOTCHA!.
Palkia first appeared in Creeping Away from Cradily. Palkia, along with Dialga, was summoned by Cyrus in order to create a new world. Cyrus used the Red Chains to force Dialga and Palkia to fight each other in order to distort time and space and create a portal that would swallow the existing world. Diamond, Pearl and Platinum worked together with their Pokémon to free Dialga and Palkia from their controlled states.
Later on, an accident with handling Charon's machine caused Dialga, Palkia and Cyrus to be dragged into the portal before it closed completely.
It was revealed that Giratina imprisoned both Dialga and Palkia in the Distortion World before setting off into the current dimension to wreak havoc. Soon, Cyrus and Diamond met in the Distortion World, and agreed to free Dialga and Palkia using their Pokémon. Dialga and Palkia later resumed their struggle against Giratina in the Distortion World. When Charon decided to escape from the Distortion World on Giratina, Pearl got on Palkia and chased after him. Giratina was eventually defeated, with Dialga and Palkia forcing it back into the Distortion World for good before both returned to the Spear Pillar.
Palkia was created in the Sinjoh Ruins, along with Dialga and Giratina, by Arceus's creation process, which was forced by Team Rocket's Executives. Knowing that the creation process would threaten the Johto region, Team Rocket's true leader Giovanni returned with Lance and Pryce to keep the creation trio at bay while Gold tried to calm Arceus down. Palkia was kept at bay by Lance and his Dragonite. Once Arceus was eventually becalmed, Dialga and Palkia departed from Johto and were spotted by Cynthia.
Palkia occasionally appears on the Spear Pillar stage as one of three Pokémon that controls it. It only appears on the stage when the ground on the upper level has a purple tinge to it. Unlike Dialga and Cresselia, however, it will use its powers to distort the stage in multiple ways. Some examples include tilting the stage, turning the stage completely upside down, and reversing the screen itself (the last two will cause the movement controls to be reversed temporarily). It often shoots beams in the cave below, dealing a lot of damage to the players that get caught in the blast.
"A Spatial Pokémon. In the Sinnoh region, this Pokémon has been revered for many generations, much like Dialga. Dialga warps time, but Palkia has control over space. It lives between parallel dimensions and is known for its power, rumored to be able to warp space. It can use Spacial Rend to rip through the very space an enemy resides in, damaging the foe at the same time. It is Pearl's mascot."
Palkia appears as a Pokémon released from a Poké Ball. It uses Spacial Rend, which flips the stage for a time, and can cause damage. Palkia also causes damage on contact.
Palkia trophy in Super Smash Bros. for 3DS
Palkia also appears as a trophy in both versions of the game.
NA: Stories surround this Legendary Water/ Dragon-type Pokémon, saying that it has control over all of space. Its Spacial Rend attack will tear space and flip the screen upside down. When this happens, the left and right controls of the fighters will become flipped as well.
PAL: Stories of this Legendary Pokémon say that Palkia is a god that controls all of space. When it uses its Spacial Rend attack in Super Smash Bros., it causes the screen to flip upside down. If that wasn't confusing enough, it also flips the left and right controls!
Palkia returns as a Pokémon summoned from a Poké Ball, using Spacial Rend like its appearance in For Nintendo 3DS/Wii U while also gaining a Spirit. Palkia cannot be summoned on 3D Land, Arena Ferox, Balloon Fight, Brinstar, Dream Land GB, Golden Plains, Green Hill Zone, Jungle Japes, Mushroomy Kingdom, Mute City SNES, Paper Mario, PictoChat 2, Prism Tower, Reset Bomb Forest, Spear Pillar (for obvious reasons), Suzaku Castle, Tomodachi Life, Tortimer Island, WarioWare Inc., or Yoshi's Island. Palkia's Spacial Rend will not be able to flip the stage upside down if a fighter is equipped with a spirit with Screen-Flip Immunity, though it will still remain on stage to damage any opponents who touch it. Palkia also reprises its role as a stage hazard on the returning Spear Pillar stage. Spear Pillar now allows for any of the three Legendary Pokémon to appear each time, rather than being set for the whole match.
Pokémon Ranger: Shadows of Almia: Palkia appears as a bonus boss during one of the Ranger Net extra missions. Palkia was injured from a battle with Dialga and entered Hippowdon Temple. In its pain, it warped the space of the Almia region and caused all of the locations of Almia to be shuffled together.
This Pokémon was unavailable prior to Generation IV.
In Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness, Palkia, along with Primal Dialga, the Legendary titans, the Magnemite family, and Regigigas, all speak in all capital letters, unlike the other Pokémon in the game.
Palkia, along with Dialga, may be based on the Shinto legend of Izanami and Izanagi, who are said to have created one island with a spear, erected a pillar on it, and from there created the islands of Japan. Appearance-wise, Palkia is likely based after a European dragon combined with a pearl. Its appearance may also be derived from the Plateosaurus or other bipedal dinosaurs such as the Oviraptor. The plates covering its face along with the crest on its neck together resemble the helmets worn by soldiers in Ancient Greece and Rome — this resemblance is made even more apparent in its Origin Forme. Its Water type is possibly inspired by its association with pearls, or the large space that oceans are known to span. Metaphorically, it could be a reference to the ever-changing forms of physical matter in the universe, with energy and matter flowing between states and changing forms. It could also refer to the Ancient Greek astronomy depicting Earth submerged in water.
Palkia's Origin Forme appears to be based on Arceus. It bears similarities to a centaur and Pegasus, a winged horse in Greek mythology. As Arceus seems to take inspiration from the qilin, this influence is seen with Origin Forme Palkia as well with its mix of equine and draconic qualities (including Palkia's Dragon typing).
Palkia may be derived from パール pāru (pearl) and galaxia.
