Spear Pillar (テンガンざん やりのはしら, Mt. Tengan Spear Pillar) is a stage in Super Smash Bros. Brawl.
Spear Pillar consists of an upper solid platform with two overhanging soft platforms at the sides, which move up and down almost constantly, and a cave in the lower part.
After a short while from the beginning of a match, Dialga, Palkia, or Cresselia will show up in the background of the stage. Which Pokémon will appear is determined by the tint of the stage. If it is tinted blue, Dialga or Cresselia will appear. If it is tinted purple, Palkia will appear. The Pokémon will perform different attacks when they appear:
Dialga and Palkia
After a while, the legendary Pokémon will vanish in a puff of smoke, leaving the brawl to continue normally for a short time. Soon enough, it will return exactly the same as before. Only one Pokémon can appear per match.
This stage is universally banned in mainstream tournaments due to the highly disruptive effect of the Pokémon's attacks - especially Palkia's which alter the players' controls - which activate randomly and suddenly. The bottom cavern of the stage also acts as a large cave of life, prolonging matches and promoting stalling. The overall stage design with the separated top and bottom areas can allow for circle camping as well.
Spear Pillar is an area in Pokémon Diamond and Pearl, situated at the top of Mt. Coronet, where the two legendary Pokémon Palkia and Dialga can be found. Team Galactic, a criminal organization which operates in Sinnoh, travels up to Spear Pillar and awaken Dialga/Palkia, bound by a crystalline Red Chain created from the lake guardians (Uxie, Mesprit and Azelf) in order to destroy the world and create a new universe where the Galactic Boss, Cyrus, is deity and king. The player character travels up to Spear Pillar, where they impede Team Galactic's plan to control the legendary Pokémon by defeating their boss. Upon defeat, Team Galactic retreats and the player has the chance to defeat or capture Dialga/Palkia. High above the Spear Pillar is the Hall of Origin, where the omnipotent legendary Pokémon Arceus resides.
