# List of generation III Pokémon

The third generation (generation III) of the Pokémon franchise features 386 fictional species of creatures and 135 Pokémon introduced to the core video game series in the 2002 Game Boy Advance games Pokémon Ruby and Sapphire, and later in the 2004 game Pokémon Emerald. These games were accompanied by the television series Pokémon Advanced, which aired from November 21, 2002, until August 28, 2003, in Japan.
The following list details the 135 Pokémon of generation III in order of their National Pokédex number. The first Pokémon, Treecko, is number 252 and the last, Deoxys, is number 386. Alternate forms that result in type changes are included for convenience. Mega Evolutions and regional forms are included on the pages for the generation in which they were introduced.

## Design and development

Pokémon are a species of fictional creatures created for the Pokémon media franchise. Developed by Game Freak and published by Nintendo, the Japanese franchise began in 1996 with the video games Pokémon Red and Green for the Game Boy, which were later released in North America as Pokémon Red and Blue in 1998. In these games and their sequels, the player assumes the role of a Trainer whose goal is to capture and use the creatures' special abilities to combat other Pokémon. Some Pokémon can transform into stronger species through a process called evolution via various means, such as exposure to specific items. Each Pokémon have one or two elemental types, which define its advantages and disadvantages when battling other Pokémon. A major goal in each game is to complete the Pokédex, a comprehensive Pokémon encyclopedia, by capturing, evolving, and trading with other Trainers to obtain individuals from all Pokémon species.
Nintendo Life noted in a retrospective that the third generation of Pokémon has a very different "feel" from the two generations that came before it because almost all of its 135 new Pokémon – save for Azurill and Wynaut – have no relation to those of the previous generations. Ruby and Sapphire features two "Mythical Pokémon" – Jirachi and Deoxys – both of which became available to coincide with their respective anime movies.
Pokémon Ruby and Sapphire significantly increased the amount of "Dark" and "Steel"-type Pokémon in the series, as only a few Pokémon in previous generations used these typings. Hardcore Gamer also noted that many of the new Pokémon made use of "dual typing", where Pokémon have both a primary and a secondary type. This was not nearly as common in Red and Blue or Gold and Silver.

| Grovyle Juputoru (ジュプトル) (0253) | Grass | Treecko (#252) | Sceptile (#254) | It uses the leaves growing on its body to camouflage itself in forests. Its thigh muscles allow it to jump between tree branches to attack or run from opponents. A Grovyle played a major role in the plot of the spin-off games Pokémon Mystery Dungeon: Explorers of Time, Explorers of Darkness, and Explorers of Sky. |
| Sceptile Jukain (ジュカイン) (0254) | Grass | Grovyle (#253) | Mega Evolution | It can slice trees down with its leaves, but prefers raising them. The seeds on its back contain nutrients. An acrobatic species, it can jump between tree branches to attack foes from above or behind. It gained a Mega Evolution in generation VI. In 2021, a newly discovered species of Anyphaena spider was named Anyphaena sceptile after the fictional species of Pokémon. |
| Torchic Achamo (アチャモ) (0255) | Fire | — | Combusken (#256) | It has a flame sac inside it, making it warm to the touch. It can spit 1,800 °F (980 °C) fireballs. It dislikes darkness because it cannot see its surroundings. During the promotion of Pokémon Ruby and Sapphire in America, a special Game Boy Advance with a Torchic theme was released at the New York Pokémon Center back in 2003. This said Game Boy Advance was also released in Japan to commemorate the 5th anniversary of the first Pokémon Centers opening up in Japan |
| Combusken Wakashamo (ワカシャモ) (0256) | Fire / Fighting | Torchic (#255) | Blaziken (#257) | It can kick 10 times per second. Its cries intimidate and distract foes. |

It can blow fire from its wrists and ankles to burn its foes. Every few years, it sheds its feathers, and new ones grow in their place. It gained a Mega Evolution in generation VI. It received an Ability called Speed Boost in generation V, which caused it to be banned to the "Ubers" tier in the Smogon competitive scene from generations V to VII, before falling to the "UUBL" tier in generation VIII, but due to the limited Pokémon roster of Brilliant Diamond and Shining Pearl, it was banned to Ubers in its competitive scene. Blaziken has received generally positive reception. IGN readers ranked Blaziken the 50th best Pokémon ever. Game Informer ranked it the 36th best Pokémon. In a poll by Official Nintendo Magazine's Tom East, Blaziken was voted the third-best Fire-type Pokémon. They stated, "A kung fu chicken? What's not to like?". In a poll of the best Pokémon from Ruby and Sapphire in celebration of the games having 10 years under their belt, Blaziken was ranked in third place. Another poll of the best Pokémon introduced in Ruby, Sapphire, and Emerald placed Blaziken third. GamesRadar used Blaziken as an example of a human-shaped Pokémon done right. The Escapist's John Funk wrote that Blaziken was an "awesome" example of a Pokémon that players who refused to play past Red and Blue were missing out on. Game Informer's Jeff Marchiafava felt that Blaziken was less cool than other Fire-type Pokémon and stated that it has a 1970s "vibe". While he felt that the Mega Evolution was an improvement, he called it a "Mega Disappointment". Kotaku's Eric Jou also felt that it had a weak design and cited it as an example of Ruby and Sapphire's weak Pokémon designs. Several critics and websites have noted that Blaziken would be a good choice for a playable character in Super Smash Bros. |
| Mudkip Mizugorō (ミズゴロウ) (0258) | Water | — | Marshtomp (#259) | The fin on its head can sense changes in the air and water currents, acting as a radar. It is strong enough to lift boulders. Videos, images and copypastas involving Mudkip began surfacing in 2005, and by 2007, the Pokémon, along with variations of the misspelled phrase "so i herd u liek mudkipz", have become internet memes which originated from a post on 4chan and received tribute videos on YouTube.

This was fixed in generation VI. |
| Nosepass Nozupasu (ノズパス) (0299) | Rock | — | Probopass (#476) | Because its nose functions as an electromagnet, it can only ever face north.

| Kecleon Kakureon (カクレオン) (0352) | Normal | No evolution | No evolution | Kecleon is a Pokémon based on chameleons. Kecleon is available to encounter in the wild as a random encounter, but could also be found invisible in set locations in the Pokémon Ruby and Sapphire's overworld. Using an item called the Devon Scope, players could reveal the Kecleon and battle them. Kecleon was one of the first Pokémon from Pokémon Ruby and Sapphire to be revealed to the public. It was showcased at an event on March 7, 2001, which first revealed the Game Boy Advance to the public. It additionally appeared in the Pokémon anime prior to its release in the games, being featured in the episode "The Kecleon Caper" in July 2001, a year prior to the release of Ruby and Sapphire. A purple Kecleon was used in promotion and was featured in the Pokémon Mystery Dungeon series, but is not obtainable in the main series games. Kecleon uses a circle motif in its design frequently used in designs found in the third generation of the series and uses contrasting colors in its design. Kecleon, to reference its chameleon origins, has a unique ability in-battle called Color Change that lets it change its type when it takes damage. Kecleon can also camouflage to appear invisible. Kecleon, unlike other Pokémon introduced in the third generation, was not immediately released into spin-off augmented reality game Pokémon Go. In an interview with Gfinity Esports in 2021, the game's Director of Global Marketing, Michael Steranka stated that the development team was taking their time due to Kecleon's unique attributes, teasing that Kecleon would be a "special release". In a later 2022 interview with TechRadar, Steranka answered that "Kecleon has unique properties in the main series games, abilities that no other Pokémon shares, so we want to make sure we do right by its original design when incorporating it into augmented reality." Steranka told Inverse in an interview that the team had set a deadline of adding Kecleon to the game by the time of the "Pokémon Go Tour: Hoenn" in-game event, which predominantly featured Pokémon from Ruby and Sapphire. Kecleon was released briefly in Pokémon Go in 2018. The Kecleon encountered in the wild would turn into the shapeshifting Ditto upon being encountered. The event coincided with the unannounced release of the then unnamed Meltan. Kecleon was eventually released in the game on January 7, 2023, over five years after the debut of third generation Pokémon in the game. To encounter it, players have to walk to in-game "Pokéstop" locations that correspond to real-world locations. An invisible Kecleon has a chance of clinging to a Pokéstop, at which point the player can tap on it in order to initiate an encounter with it. This method of encounter was designed to encourage players of the game to go outside again following the COVID-19 pandemic. Kecleon's inclusion in Pokémon Go was a source of major discussion. Due to being the last Pokémon introduced in Pokémon Ruby and Sapphire to be added to the game, fans of the series were unsure of why the Pokémon had not yet been included, leading to frequent discussion over when it would debut. The hashtag, "JusticeForKecleon" grew popular with fans of the series, and was used as a rallying cry for Kecleon's inclusion. Kecleon's lack of inclusion was considered a meme within the community. Inverse's Steven Asarch stated that while Kecleon was a predominantly unpopular and forgettable Pokémon in the main series games, it had become an elusive figure among fans of Pokémon Go due to its lack of inclusion. Kecleon has been described as being the most anticipated Pokémon addition in the game's history, and its eventual release in the game was received positively. TheGamer's Stacey Henley, prior to Kecleon's addition to the game, stated that Kecleon was "more interesting to think about than it is to actually use", believing that while players had nostalgia over its role in prior games, the Pokémon was unpopular overall. She stated that Kecleon's addition "put Niantic into an impossible position", believing that releasing Kecleon without fanfare would make players question why Kecleon's addition had taken so long, but that Kecleon itself was a Pokémon that was unable to drum up excitement in the game's player base if more focus were to be put onto its release. She finished by saying that while Kecleon could be an interesting inclusion if executed correctly, Kecleon was uninteresting enough that the species was unable to drum up significant excitement. Ben Sledge, also writing for TheGamer, stated that Kecleon's eventual inclusion in the game had an enjoyable implementation that was not tied to any in-game timed event, believing that its rarity in-game was an effective method of keeping the Pokémon interesting after its release. However, he felt that the eventual release of the Pokémon felt underwhelming overall. |

## Reception

Reception to generation III's Pokémon has been polarized. Alex Carlson of Hardcore Gamer wrote in 2014 that the third generation of Pokémon games was not well received by fans of the series, with some people calling the generation the "worst in the series history". This was in part because Ruby and Sapphire did not allow players to transfer in their Pokémon from previous generations and, because of this, many older Pokémon were completely unavailable in the games until Pokémon FireRed and LeafGreen were released a few years later. Meanwhile, many of the new Pokémon designs, such as those for Torchic, Feebas, Luvdisc, Castform and Clamperl, were criticized for being unoriginal. Contrastingly, some designs, including Breloom, Aggron, and the aforementioned Castform were praised for their coolness, with the large variety of unique legendary Pokémon also helping the third generation feel fresh and new. While Ruby and Sapphire were recognized for introducing less memorable designs than their predecessors, designs like Milotic, Salamence, Metagross, Rayquaza, and Blaziken made the overall generation a satisfying supplement to the existing Pokédex.
The third generation has had its share of enduringly popular designs. Eighteen years after the release of Ruby and Sapphire, Rayquaza and Gardevoir finished eighth and ninth in 2020's Pokémon of the Year vote, with Flygon, Sceptile, and Blaziken also among the top 30. Rayquaza also finished eighth in a 2016 Japanese poll, with Jirachi and Kyogre among the top 25. A popularity vote on the Pokémon subreddit featured Blaziken at 5th, joined in the top 25 by Gardevoir, Absol, Flygon, and Mudkip.
