Pokémon Red and Blue · Game Boy · 1998 · Japan → North America
Bringing Pokémon out of Japan meant renaming all 151 creatures for Western audiences, trademarking each new name, and reprogramming the games — a sweeping localisation effort that launched one of the biggest entertainment franchises in the world.
Pokémon Red and Green were a phenomenon in Japan, but transforming them into the global juggernaut Pokémon Red and Blue required one of the most consequential localisation efforts in gaming history. In January 1998, Gail Tilden was tasked with leading the team that would bring Pokémon out of Japan to the rest of the world, and the reprogrammed Red and Blue versions — retaining the original creature designs — were released in North America on 28 September 1998. The scale of the task went far beyond translating menus and dialogue. The defining challenge was the Pokémon themselves. A small team, led by Hiro Nakamura, worked through all 151 creatures and gave each a new English name chosen to reflect its appearance and characteristics, subject to Nintendo's approval — Zenigame became Squirtle, Hitokage became Charmander, and so on across the entire roster. These were not mere transliterations but deliberate, evocative rebrandings, many built on English puns and descriptive roots that gave the Western Pokémon their own distinct identities. Crucially, Nintendo trademarked all 151 new names, ensuring the franchise's creatures would be legally unique and protected worldwide — a foresighted move given what the brand would become. The process was iterative and imperfect. During the promotional run-up to the Western launch of both the games and the animated series, many Pokémon were shown with provisional names that differed from the finals — early candidates like Goldy (Goldeen), Neptune (Seaking), Jilly (Tentacool), Slowmo (Slowpoke), and Dragoon (Dratini) circulated before being replaced. Some early names hewed close to the Japanese originals, others were completely different, and the team refined them toward the memorable set that players ultimately received. There were technical hurdles as well. The Japanese games allowed only a five-character limit for Pokémon names, and the localisation team had to expand the game's systems to accommodate longer English names — the final international versions of Red and Blue permitted up to ten characters. This required genuine reprogramming rather than simple text substitution. The success of this comprehensive effort — new names, legal protection, expanded systems, and a coordinated launch alongside the anime and trading cards — helped ignite "Pokémania" in the West and turned a Japanese Game Boy RPG into one of the largest media franchises on the planet.
The heart of the Pokémon localisation was the wholesale renaming of every creature. A small team under Hiro Nakamura studied each of the 151 Pokémon and devised English names that captured its look and nature — a process closer to branding than translation, producing pun-laden, descriptive names like Squirtle, Charmander, and Bulbasaur that became instantly iconic. Nintendo then trademarked all 151, a legally significant step that protected the franchise's creatures worldwide and reflected an unusual confidence in the brand's potential. The provisional names that leaked during the pre-launch promotional period — Goldy, Neptune, Dragoon and others — show how much iteration went into arriving at the final, now-beloved roster of English names.
Localising Pokémon demanded real engineering, not merely swapping text. The Japanese games were built around a five-character limit for names, and accommodating longer English Pokémon names meant expanding the game's systems to allow up to ten characters in the international versions — a change that required reprogramming rather than simple substitution. Combined with translating the script, rebranding all 151 creatures, and coordinating the release with the animated series and trading-card game, this made the Western launch a comprehensive redevelopment effort. Its success in September 1998 sparked "Pokémania" across North America and demonstrated how thorough, well-resourced localisation could turn a regional hit into a global cultural force.
