# List of Pokémon rivals

The Pokémon franchise, which began in 1996, is a series of turn-based JRPG games. In each game, the player strives to become the Champion—the strongest trainer in a given region. Along the way, they often encounter various rival characters. These rivals, who can range from antagonistic to friendly, serve as significant challenges for the player, sometimes culminating in a final confrontation. The concept of rivals in the Pokémon series has garnered both praise and criticism for its different implementations throughout the franchise.

## Role

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

## Rivals
### Blue

Blue Oak, known in Japan as Green Okido (オーキド・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. 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!. 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.

## Reception

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. Despite this, rival characters such as Blue and Silver established a dynamic of rival that have proven popular with fans of the series. 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. 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. 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. 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. 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.
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. 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, though it did receive some praise due to its apparent self-awareness of Hop's role as a "kind" rival. 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. 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. 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.
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, 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. The lack of backstory and personality in other rivals was also deemed to make several rival characters less compelling than later rivals, 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. Scarlet and Violet were highlighted for their unique departures from traditional rival formulas. Arven's storyline, for instance, was praised due to its strong emotional narrative and conclusion throughout the plot of the game, 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.
