Pokémon

Pokémon are a non-Mario species, which is currently made up of 493 members, in the Pokémon Series, that each have unique abilities. There are 17 different elemental types of Pokémon; each element affects what the Pokémon's attacks, abilities and weaknesses are. For example, Pikachu, being an Electric Pokémon, specializes in electrical attacks, which can easily defeat Flying and Water Pokémon, but in turn are weak against Grass Pokémon and ineffective against Ground Pokémon. Another factor that separates Pokémon from traditional animals is that after meeting certain conditions, the Pokémon evolves into a new Pokémon. For example, a Pichu can evolve into a Pikachu, and a Pikachu can then later evolve into its final form Raichu. Pokémon live in the wild, but are caught by Pokémon Trainers to have as pets or to battle with other Pokémon competitively.

Some select Pokémon have interacted with characters in the Mario series, most notably in the Super Smash Bros. competitions. Not only are some competitors, but if a player throws a Poké Ball, then a random Pokémon comes out and effects the gameplay in some way. These Poké Ball Pokémon don't hurt the player who sent them out, with the exception of Electrode and Wobbuffet.

In Spear Pillar, one of the three Pokémon above will appear periodically to attack fighters or change the stage itself. Dialga can slow down time as well as create a red burst of energy from its body, damaging fighters. Palkia can reverse the stage, also reversing the controls. Both Pokémon can cause parts of the stage to crumble, rotate the stage anywhere from slightly to 180 degrees, and create a laser beam that will damage players.

Cresselia is somewhat rarer and its only attack is flinging large crescent-moon shaped barbs around the stage. It cannot alter the stage in any of the ways Dialga and Palkia can.

Trivia

 * All of the Pokémon that appear in Poké Balls in Super Smash Bros. Melee are based on their design in the game Pokémon Stadium 2.
 * Additionally, in Super Smash Bros. Brawl, the 3rd generation Pokémon and 4th generation Pokémon that pop out of Poké Balls are based on their designs from the games Pokémon Colosseum and Pokémon Battle Revolution.
 * Pokémon was one of the two series from the original Super Smash Bros. that were not included in Nintendo Monopoly, the other being the Earthbound series. A probable reason for not including the Pokémon series is that a Pokémon-themed Monopoly game had already been made.
 * In the opening cinema of Super Smash Bros. Melee, several Pokémon appear at the same time. Oddly, many of them do not appear in Pokéballs, nor do they have trophies.
 * Similarly, several Pokémon appear as floats in Poké Floats, who have the same case as the aformentioned Pokémon.
 * Jigglypuff and Pichu both make an appearance in the Pokémon shot featured in the cinematic opening, despite that they are secret characters. This "honor" is shared with Ganondorf, whose arm appears in the opening.
 * Of all Nintendo series put into Super Smash Bros. Melee, the Pokémon series had the most unlockable playable characters; Jigglypuff, Pichu, and Mewtwo.
 * Mewtwo, along with Plusle and Minun, were meant to be in Super Smash Bros. Brawl, but were taken out. Mewtwo's reason was that Lucario was added. Plusle and Minun would've functioned together in the same manner as the Ice Climbers.
 * Pokémon is a combination of the words "pocket" and "monster".
 * A controversy has spawn of how to say pokémon. Some beleive it is said as pokEmon (with a higher case "e"), other beleive it's said with a lower case "e" as some characters in the series say it like that. A rare belief is it is said with an "a" where the "é" is at, since "é" is supposed to be said as an upper case "a".
 * In Super Smash Bros. Brawl, only the playable Pokémon and the Poké Ball Pokémon have stickers of themselves. The only exception to this is Rayquaza, where it has its own sticker, despite being only a boss.
 * All the Pokémon Stickers in Super Smash Bros. Brawl are actually from that game. However, there are already the Main Game arts for all those Pokémon made by Ken Sugimori, so it's unknown why these aren't used instead of the Super Smash Bros. Brawl artworks.
 * In Super Smash Bros. Brawl, there is a one in 493 chance for Mew, Jirachi, and Celebi to appear. This likely refers to how many Pokémon have been created by the time Super Smash Bros. Brawl was released, starting with Bulbasaur and ending with Arceus.
