List of Pokémon rivals

Developed by Game Freak and published by Nintendo, the Pokémon franchise began in Japan in 1996 with the release of the video games Pokémon Red and Blue for the Game Boy.^[1] In these games, the player assumes the role of a Pokémon Trainer whose goal is to capture and train creatures called Pokémon. Players use the creatures' special abilities to combat other Pokémon, both in the wild as well as those used by other Trainers.^[2]

Notable Trainers in most installments are "rival" characters. Rivals are recurring characters in the games, often acting as roadblocks for the player due to their heightened difficulty compared to usual NPC Trainer battles.^[3] The first rival was introduced in Pokémon Red and Blue, with the character Blue. Blue is a standoffish character who antagonizes the player, and acts as the game's final boss.^[4]

Rival characters often differ in terms of their perception towards the player. Some rivals are similar to Blue in characterization- such as Silver^[5] and Bede^[6]- while other rivals are more friendly towards the player and engage in battles for fun, such as Brendan, May,^[7] and Hau.^[8] The latter are often more actively supportive of the player,^[9] whereas characters such as Blue often act in direct competition to the player.^[4] Some rivals, such as Cheren,^[10] Hop,^[3] and Kieran,^[11] end up going through character arcs during their rivalry with the player.^[3]

Blue Oak, known in Japan as Green (グリーン), is the grandson of the esteemed Professor Samuel Oak. Hailing from Pallet Town, he grew up alongside the game's protagonist, and acts as their rival throughout the game. He is always a step ahead of the player, often completing major milestones before the player does. He is very smug, often gloating about his skill compared to the player, though after his defeat at the end of the game, he begins to mellow out.^[4] He reappears in Pokémon Gold, Silver, and Crystal, where he acts as a Gym Leader, and subsequently reappears in the games' remakes, Pokémon Black 2, White 2, Sun, Moon, Let's Go, Pikachu!, and Let's Go, Eevee!.^[12] He also appears in Pokémon Stadium and its sequel, acting as the final boss of the former. Blue also appears in Pokémon Masters EX.

A counterpart to Blue, named Gary Oak, known in Japan as Shigeru Okido (オーキド・シゲル), appears in the Pokémon anime, where he serves as a rival to series protagonist Ash Ketchum.^[13] After being defeated during the original series, he begins to mellow out, and subsequently becomes a Pokémon Professor in Pokémon the Series: Diamond and Pearl. He later reappears in Pokémon Journeys: The Series, acting as a recurring character who appears as part of "Project Mew." Gary later appears in the spin-off Pokémon Puzzle League. A counterpart to Blue also appears as a major character in the Pokémon Adventures manga series.^[12]

Silver is the son of Giovanni, the leader of the criminal organization Team Rocket, who first appeared in Pokémon Gold and Silver. Following Giovanni's defeat at the hands of the player character of the original games, Silver ran away from his father. He ended up stealing a Pokémon from Professor Elm, and seeks to become the strongest Pokémon Trainer in the world. He prioritizes strength above anything else and is implied to be cruel to his Pokémon throughout various points in the game. After a defeat at the hands of Lance, the Champion of Johto, Silver begins to reconsider his style of battling, and matures as a character following this.^[5]

Silver appears in Pokémon Stadium 2 as a major boss opponent, while another incarnation of him appears in Pokémon Adventures. He later appeared in Pokémon Masters EX, where he was paired up alongside the Legendary Pokémon Ho-oh.^[14]

Brendan and May are the children of Professor Birch, a Professor in the Hoenn region, who first appeared in Pokémon Ruby and Sapphire. The one that is the player's rival will be of the opposite gender to that of the player: if the player selects Brendan, their rival will be May, and vice versa. Brendan and May assist Professor Birch with his research, and fight the player at various points throughout the game throughout the game.^[15]

The pair reappear in Pokémon Masters EX,^[16] though Brendan is Norman's child in that game, while May is Birch's. Counterparts to them appear in Pokémon Adventures, while another counterpart of May takes on a main character role in the Pokémon anime.

Wally is a young boy who appears in Pokémon Ruby and Pokémon Sapphire. He is a sickly child who is moving away when the player first meets them. The player helps them catch a Ralts for companionship, and Wally later reappears at various points to challenge the player, culminating in a final battle just before the Hoenn Pokémon League.

After the player convinces him to abandon his goals, and Ghetsis is defeated, N flies away on his Pokémon. He later reappears in Pokémon Black 2 and White 2, saving the player character of that game from being killed by Ghetsis. After Ghetsis's defeat, he can be found in the ruins of his castle, where he will challenge the player to a final battle with his Legendary Pokémon.^[18]

Kieran starts out as a kind, albeit shy boy at first, who has a strong liking towards the Legendary Pokémon Ogerpon due to growing up on legends about it. When Ogerpon is discovered by the player and Carmine, Kieran is left out of the discovery. After finding out about the deception, he grows spiteful towards the player and resolves to grow stronger. He becomes the Champion of Blueberry Academy's BB League, but is dethroned by the player. He later joins them on an expedition to Area Zero alongside Carmine, where he captures Terapagos in an attempt to grow stronger. Terapagos breaks free, and he later assists the player in stopping it.^[11]

Early rivals were often defined by their general negative and "jerkish" attitude, and have defined the role for years afterwards. According to series director Junichi Masuda, the shift from this attitude to a more friendly one was due to greater freedom with the hardware as games developed, as well as a general distaste by the public to that kind of character.^[33] Despite this, rival characters such as Blue and Silver established a dynamic of rival that have proven popular with fans of the series.^[25] Blue's smug attitude and method of always one-upping the player in Red and Blue is considered highly iconic and a large part of what made the first games engaging for players. His eventual development in the subsequent games was met with praise.^[4] Blue's goals of becoming the strongest trainer and his significant challenge as a roadblock also helped highlight this, as it allowed the player to grow prouder upon defeating him while also echoing the franchise's core themes.^[3][9] Similarly, Silver's more nuanced character arc while still being painted as an antagonistic figure has been cited as helping to build a compelling character for the player to fight, with his further growth enabling for the rivalry with the character to feel rewarding.^[5] Blue and Silver's character highly influenced later rivals. Characters such as Bede and Carmine were both considered positively in comparison to Blue due to their return to the character archetype, with both receiving praise for their individual character arcs.^[6][11] The Isle of Armor's Klara and Avery were also highlighted due to their personalities and more intentionally negative attitudes, while also receiving positive reviews for the fact their attitudes served a role beyond the plot.^[24]

The transition into kinder rival characters was met with mixed responses. The overall positivity of characters such as Hau and Hop made many feel like their victories against them were not earned and potentially mean.^[3] In particular, Hop's subsequent character arc surrounding his constant losses was described as putting the player into a similar position to Blue in terms of their role,^[34] though it did receive some praise due to its apparent self-awareness of Hop's role as a "kind" rival.^[22] Hau's role was also cited similarly, due to the fact that the player's rivalry with Gladion was significantly stronger than with Hau, who was nothing but supportive of the player.^[8] Kieran, one of the rivals of Scarlet and Violet's DLC expansion, bore a similar character arc, which produced praise for evolving an initially kinder rival into one with a similar set of characteristics to those of Blue and Silver.^[11][35] Despite this, the shift to kinder rivals was highlighted positively due to the fact that it no longer used meaner antagonistic rivals to encourage the player, which was considered potentially harmful as a message to younger audiences.^[9]

The lack of difficulty also contributed to the "kinder" rivals being met with a less positive critical response, with the battles with Brendan and May in the Hoenn-based games and the rivals of Pokémon X and Y being highlighted as forgettable due to the lack of challenge,^[25] though Hop's battling inexperience was highlighted for its ability to aid in the development of his character throughout the plot of Sword and Shield.^[22] The lack of backstory and personality in other rivals was also deemed to make several rival characters less compelling than later rivals,^[36][25] such as Nemona from Scarlet and Violet. Nemona in particular was considered more compelling due to having a unique and interesting character that did not fall into similar character archetypes to previous rivals.^[25][37] Scarlet and Violet were highlighted for their unique departures from traditional rival formulas.^[29] Arven's storyline, for instance, was praised due to its strong emotional narrative and conclusion throughout the plot of the game,^[28] while Nemona's was considered a call for more unique rival characters in future installments that did not fall into the "mean" or "kind" archetypes of past games.^[38]
