As a stage element
Palkia is one of three Legendary Pokémon that can appear and cause battle effects on the Spear Pillar stage, alongside Dialga and Cresselia. When the stage has a pink tint, Palkia is the Pokémon for the match. Palkia can cause several different effects on the battle:

 * Firing a vertical pink Hyper Beam covering a third of the stage, either the left, right or middle.
 * Firing a horizontal pink Hyper Beam through the cave area.
 * Halving gravity and weight for all fighters.
 * Mirroring the screen, such that pressing right causes a character to appear to move to the left.
 * Rotating the screen at a 180-degree angle, causing it to appear upside-down.

As a Poké Ball Pokémon
Palkia can appear from Poké Balls and Master Balls. When summoned, Palkia uses its signature move, temporarily turning the camera upside down. It disappears after a short time, returning the camera to normal. Opponents who touch Palkia take 10% damage and low knockback.

Trophy

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 (as it already appears there), Suzaku Castle, Tomodachi Life, Tortimer Island, WarioWare Inc., or Yoshi's Island.

Palkia's Spacial Rend will not be able to flip the screen 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.

Trivia

 * Palkia is one of four Pokémon to be both a Poké Ball summon and a stage element in the same installment, as it returns as both in Ultimate. Chansey was the first with this distinction, appearing in Super Smash Bros., while Electrode and Scizor also return as both in Ultimate.
 * Palkia is also the only Legendary Pokémon with this distinction.
 * Because of this, Palkia cannot be summoned at Spear Pillar in Ultimate.
 * When a player gets Screen KO'd while Spacial Rend is active, they will technically fall upwards instead of downwards.
 * Palkia's roars in Brawl are a combination of sound effects of the Varactyl from the Star Wars film franchise and Godzilla roars from the Godzilla film franchise. A similar case occurs with Lunala in Ultimate, who uses the cry of Mothra from the Godzilla franchise.
 * Its roars as a Poké Ball Pokémon replace the Godzilla roars with roars of King Ghidorah, who is also from the same franchise.
 * Palkia's roar is not heard in the game's Sound Test outside of Brawl.
 * During Spacial Rend in Smash 4, the magnifying glass will not properly show the character's vertical position, showing characters going towards the lower blast line (which is now at the top of the screen) as going towards the upper blast line and vice versa. The vertical position is accurate to if the screen was not rotated. This does not occur for the horizontal position, which is properly reflected, unless the upper or lower camera bounds are crossed, in which case the horizontal position is flipped and is accurate as if the screen wasn't rotated. This results in confusing scenarios where a character who is launched towards the upper-right (bottom-left in the rotated view) will have the magnifying glass appear towards the bottom-right (upper-left), unless they pass the upper (bottom) camera bound in which case the magnifying glass will appear to the bottom-left (upper-right).
