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 the anime, Palkia is shown to be capable of levitation in the same manner as Dialga and Arceus.

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. A proverb states that Palkia's birth created the world's sky.

Palkia has the power to create a new universe by itself or with . 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 was feared as a deity in Sinnoh myths; in the past, it was worshipped by the Pearl Clan, who referred to it as "almighty Sinnoh". Palkia is capable of speaking through telepathy, as seen when it communicates through the leader of the Pearl Clan, Irida. Palkia and Dialga can control and spread the space-time distortions caused by , which create alpha Pokémon and cause Noble Pokémon to go berserk.

Forms
Palkia can change between its standard form and its Origin Forme.

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, . 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.

Palkia is at its full power when in the Origin Forme and is supposedly, permanently in it while in its home dimension. 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 or through a radiant light. Origin Forme Palkia can walk on all fours and fly, and is capable of unleashing meteors and shockwaves. Its Spacial Rend can even be charged into a more powerful version of itself while in Origin Forme, as seen in its boss battle in Pokémon Legends: Arceus. The crystals and purple accents on Palkia's body glow brightly when it uses its powers.
