Ninety-six. That is the number you need to remember if you want to understand where the obsession actually started. While the official count for the original Kanto region is 151, the internal index numbers in the Red and Blue game code actually stopped at 190. The "missing" slots were filled with MissingNo data—glitches that became legends. It’s wild to think about. We aren't just talking about a bunch of digital monsters; we’re talking about a cultural foundation that was almost a total disaster during development.
Honestly, the Gen 1 Pokémon shouldn't have worked. The Game Boy was ancient technology by 1996. The sprites looked like weird, melting lumps of clay in the Japanese Red and Green versions. But here we are, decades later, and if you show a silhouette of a round yellow mouse to a person in a remote village, they’ll probably yell "Pikachu." It’s basically unavoidable.
The Design Philosophy Nobody Replicates Anymore
Modern Pokémon designs are busy. There, I said it. If you look at a Gen 9 creature, it often has specific "clothing" elements or complex patterns that tell a very specific story. Ken Sugimori’s original Gen 1 Pokémon designs followed a "rule of three" or less. They were based on shapes you could draw from memory after seeing them once. Think about Voltorb. It’s a ball with eyes. Diglett? A thumb with a nose.
This simplicity wasn't just an aesthetic choice; it was a technical necessity. The Game Boy’s screen resolution was tiny. If a design was too complex, it turned into a pixelated mess. This forced the designers at Game Freak to focus on silhouette and "readability." You knew exactly what Blastoise was because he was a turtle with literal cannons sticking out of his back. It was literal. It was visceral. It worked.
People often complain that "modern Pokémon are running out of ideas," but they forget that Gen 1 had a pile of sludge (Grimer) and a bird that is just a bird (Pidgey). The difference is the nostalgia filter. We forgive the simplicity of the originals because they feel like actual animals you might find in the woods behind your house, rather than over-designed characters from a high-fantasy anime.
The Weirdness of the Original Typing
If you go back and play the original games today, you’ll realize the competitive balance was a complete nightmare. Psychic types were essentially gods. There was a literal bug in the programming where Psychic-type Pokémon were immune to Ghost-type moves, even though the game dialogue explicitly stated that Ghost was the only weakness for Alakazam.
Wait, it gets worse. The only "strong" Ghost move was Lick. You were expected to take down a genius psychic spoon-bender by licking him. It was a mess.

Then there's the Focus Energy bug. In the original code, using Focus Energy actually divided your critical hit ratio by four instead of increasing it. You were literally paying a turn to make your Pokémon worse. This kind of jank is why the community around the original 151 is so dedicated. We spent years figuring out how to break a game that was already held together by digital duct tape and hope.
Why Charizard Is the Exception to Every Rule
We have to talk about the lizard in the room. Charizard.
In terms of raw data, Charizard wasn't even the best starter. Bulbasaur was the "objective" choice for a speedrun because he countered the first two gyms perfectly. But Charizard had something else. He had a design that tapped into a universal childhood lizard-brain desire for a dragon. Even though he wasn't technically a Dragon-type until Mega Evolution showed up years later, he represented the peak of the Gen 1 Pokémon hierarchy.
Did you know the holographic Charizard card from the Base Set wasn't even the rarest card? It was just the most desired. Supply and demand were driven entirely by playground status. If you had that card, you were the king of the blacktop. It didn’t matter that Chansey had more HP or that Alakazam was faster. The "cool factor" of the original designs created a secondary economy that still exists today in the grading rooms of PSA and BGS.
The Mew Under the Truck Myth
Before the internet was a utility, we had rumors. The most famous one involved a parked truck near the S.S. Anne in Vermilion City. Everyone "knew" someone whose cousin had found Mew under that truck.
The reality? The truck was just a static tile the developers never thought players would reach after the ship sailed. Mew was actually added at the very last second by Shigeki Morimoto. He crammed the data in after the debugging tools were removed, leaving just enough space for one more creature. It was a massive risk. If Mew had caused a game-breaking bug, the entire launch would have been ruined. Instead, it became the first true "mythical" gaming secret.

The Cultural Shift of the "151"
There’s a reason why The Pokémon Company keeps returning to Kanto. We’ve seen FireRed, Let’s Go Pikachu, and countless regional variants of the original cast. It’s because the Gen 1 Pokémon are the only ones that bridge the generational gap.
A 35-year-old father can sit down and play with his 7-year-old daughter, and they both know who Gengar is. That is a level of brand penetration that most companies would kill for. It’s not just about the games; it’s about the fact that these designs were built on universal archetypes.
- Arcanine: The loyal "legendary" dog.
- Snorlax: The relatable embodiment of a food coma.
- Meowth: The personification of greed and luck.
These weren't just monsters; they were personalities. The anime helped, sure. Seeing Ash’s Butterfree leave was a traumatic event for an entire generation. But the foundation was always the sprites.
The Problem with Modern "Kanto Pandering"
If you spend any time in the Pokémon fandom, you’ve heard the term "Kanto Pandering." This is the idea that Game Freak relies too heavily on the original 151 to sell new games. While it’s true that Charizard gets more "special forms" than almost any other creature, there’s a business logic here.
When Pokémon GO launched in 2016, it only featured the original cast. Why? Because that’s what the "lapsed" fans remembered. The developers knew that to capture the mass market, they had to lead with the heavy hitters. You don't lead with a trash-can monster from Gen 5 when you're trying to convince a 40-year-old lawyer to walk around a park at lunch. You lead with Squirtle.
Actionable Steps for Collectors and Fans
If you’re looking to dive back into the world of the original 151, don’t just buy the first thing you see on eBay. The market is flooded with fakes.

First, if you're looking for the games, check the internal battery. Original copies of Pokémon Red, Blue, and Yellow use a CR2025 or CR2032 battery to maintain save files. If the battery is dead, you can’t save. It’s an easy fix with a soldering iron, but it’s something to be aware of.
Second, look into "Glitch Hunting." If you still have your original hardware, try the "Long-Range Trainer" glitch. It’s a reliable way to catch Mew in the original games without using a GameShark. It’s a rite of passage for any serious fan.
Third, pay attention to the "Japanese Noad" era. If you're collecting cards, the Japanese "No Rarity" Base Set is the true holy grail for many, predating the 1st Edition English release. It’s a deeper level of hobbyism that many people miss.
The Gen 1 Pokémon aren't just a list of names. They are a weird, glitchy, perfectly designed miracle of 90s technology. They survived a black-and-white screen and turned into a multi-billion dollar empire. Whether you think they’re overrated or the peak of the series, you can’t argue with the fact that they changed how we think about digital companions forever.
For those wanting to truly master the Kanto history, start by researching the "Capsule Monsters" pitch deck. Seeing the original sketches of "Rhydon"—the first Pokémon ever programmed—gives you a whole new appreciation for how far we've come. Check out the archives on DidYouKnowGaming or Bulbapedia for the deep-dive translations of the original developer interviews. Knowing the "why" behind the design makes the "what" a lot more interesting.
