For a whole generation of players who discovered the franchise in the late 1990s on the monochrome screens of the Game Boy, the number 151 carries an almost mystical aura. From Bulbasaur to Mew, those one hundred and fifty-one creatures etched the foundations of an unparalleled cultural phenomenon into our collective unconscious. Yet behind this immaculate numbering and the legendary slogan “Gotta catch ’em all!”, the development story of Pokémon Red and Blue hides a fascinating technical reality: dozens of creatures made by the team of Satoshi Tajiri and Ken Sugimori never made it onto the cartridges of our childhood.
What became of these Pokémon erased from history? How did the tiny memory of a 512-kilobyte Game Boy cartridge force Game Freak into agonizing trade-offs, giving rise both to the famous MissingNo. glitch and to mythical monsters that stayed in the shadows for two decades? From the true third evolution of Pikachu to the treasures buried in the Nintendo Spaceworld 1997 demo, our exclusive investigative report dives into the source code and the Japanese archives of the saga’s creation.
In this major investigation reserved for PF Premium members, we retrace the entire chronological puzzle linking the preliminary sketches of Capsule Monsters (1990) to the final versions of Pokémon Gold and Silver (1999). Among other things, you will discover the designers’ confidences about Gorochu, the hexadecimal analysis of Kanto’s 39 vacant memory slots, and our exclusive table listing the fate of each of these forgotten Pokémon.
