List of Pokémon
At the core of the Pokémon franchise are hundreds upon hundreds of the eponymous creatures. These are collectively called Pokémon and have many roles in the Pokémon RPGs, mainly as game pieces in Pokémon battling where the object is to defeat the opponent's enemy Pokémon with their own. Pokémon are introduced en masse once every several years as part of a new "Generation" of the franchise, along with the newest handheld RPG versions. Thus far there have been a total of seven generations, with the grand total of species clocking in at 812 different species of Pokémon, and each Super Smash Bros. game features a selected assortment of Pokémon from all current generations existent at its time to serve a variety of roles, such as playable character, character that is summoned from an item called the Poké Ball, collectible trophy or sticker, background characters in stages, and others.
All listed Pokémon that are bolded have the major roles of either being playable characters, appearing from a Poké Ball item, or appearing as an enemy (boss, Smash Run, etc.). Others have more minor roles.
The Pokémon franchise began in 1996 with 151 Pokémon species from the Kanto region featured in the very first versions of the Pokémon RPGs, Pokémon Red and Blue for the original Game Boy. This was the only generation in effect when Super Smash Bros. was developed and released.
Appearances marked with an asterisk (*) are unavailable without external means, such as hacking.
The Pokémon franchise entered its second generation in 1999 with 100 new Pokémon species from the Johto region added to the original 151 to form a total of 251 Pokémon, and all were featured in the RPGs Pokémon Gold and Silver for Game Boy Color. These two generations were in effect when Super Smash Bros. Melee was developed and released.
The Pokémon franchise entered its third generation in 2002 with 135 new Pokémon species from the Hoenn region added to the previous 251 to form a total of 386 Pokémon, first featured in the RPGs Pokémon Ruby and Sapphire for Game Boy Advance. This generation's first appearance in a Smash Bros. game, Super Smash Bros. Brawl, also happens to be the first appearance of the Fourth Generation that was put in effect an entire four years later, owing to the relatively long time period between the releases of Melee and Brawl.
The Pokémon franchise entered its fourth generation in 2006 with 107 more new Pokémon species from the Sinnoh region added to the previous 386 to form a total of 493 Pokémon species, and all are featured in the Pokémon RPGs, Pokémon Diamond and Pearl for Nintendo DS. Both this and the previous generation make their Super Smash Bros. debut in Brawl.
The Pokémon franchise entered its fifth generation in 2010 with 156 more new Pokémon species from the Unova region added to the previous 493 to form a total of 649 Pokémon species, starting in Pokémon Black and White for Nintendo DS. Pokémon from this generation first appear in Super Smash Bros. 4. So far, this is the generation to introduce the most species of Pokémon.
Pokémon X and Y for Nintendo 3DS, representing the sixth generation of the series, were released in 2013, and added 72 more new Pokémon species from the Kalos region to the previous 649 to form a total of 721 Pokémon species. Pokémon from this generation first appear in Super Smash Bros. 4. So far, this is the generation to introduce the least species of Pokémon.
Pokémon Sun and Moon for Nintendo 3DS, representing the seventh generation of the series, were released in 2016 and added 81 new Pokémon species from the Alola region to the previous 721 to form a total of 802 Pokémon species. They were followed by Pokémon Ultra Sun and Ultra Moon in 2017, which added 5 more new species mid-generation (a series first), bringing the total up to 807 Pokémon species. Pokémon from this generation first appear in Super Smash Bros. Ultimate.
