As a huge fan, I can honestly say Pokémon just keeps getting better! Ever since it first came out in the late ’90s, it’s given me and millions of others countless hours of fun with amazing games. Whether it’s the classics like Red & Blue, newer titles like Let’s Go, Pikachu, or the recent spin-off Pokéopia, Nintendo really knows what they’re doing with this franchise. It’s no surprise it’s become one of the biggest media franchises ever – there’s just something so captivating about it. Pokémon has everything I want in a game: cute monsters, challenging battles, and worlds to explore. Plus, the games are always full of secrets, which is awesome for anyone who loves a good mystery!
For three decades, the Pokémon games have been filled with hidden secrets, or ‘Easter eggs,’ that fans love to find. Some, like the way to find the rare Pokémon Mew or the glitch Pokémon MissingNo, have become legendary among gamers. But many other fascinating secrets remain undiscovered. From subtle animations to strange things NPCs do, Pokémon hides a lot of intriguing details that don’t get enough attention. ScreenRant has compiled a list of 10 of these overlooked secrets, so you can see if you missed them!
1. Pikachu vs. A Dark Cave — Pokémon Yellow
When Pokémon first became popular in the late 1990s, the original games were full of hidden surprises that amazed players. Not only did Pokémon Red & Blue show everyone what Nintendo was capable of, but subsequent releases encouraged fans to search for even more secrets. In Pokémon Yellow, dedicated players were rewarded for their exploration with an incredibly well-hidden detail found inside a cave. If you take Pikachu into a dark cave and teach him the move Thunder, he’ll light up the map by charging his cheeks, briefly illuminating the entire area. It’s a small, unexpected detail that went unnoticed for years.
2. Nintendo Takes a Shot at Sony — Pokémon Red & Blue
The rivalry between Sony and Nintendo is legendary in the video game world, stretching back decades as their consoles have competed for dominance. This competition was particularly fierce around the time Pokémon Red & Blue were released, and a recent discovery reveals a hidden jab at Sony within the game. A ROM hack uncovered a detail in the debug version of Red & Blue: the player character is initially named ‘NINTEN,’ while their rival is named ‘SONY.’ While players never see these default names in the actual game—Professor Oak asks you to name your character—the hack brought this playful dig to light many years after the game’s release.
3. A Wild Kirby Appears — Pokémon Diamond & Pearl
Nintendo is famous for creating beloved gaming characters like Mario and Link. While many of these characters appear as references within the Pokémon games, Diamond & Pearl included a particularly clever nod to Kirby. In the Lost Tower, players encounter a trainer named Kirby who battles them using Cleffa, a Pokémon that strongly resembles the pink puffball. This understated cameo is one of Nintendo’s more subtle and often missed references, making it a fun discovery for dedicated gamers.
4. Pokémon Santa Is a Real Thing — Pokémon Sun & Moon
While much of the Pokémon world remains a mystery, one thing is clear: Santa Claus is real, and he’s actually a Pokémon! Players who explored Team Skull’s Shady House in Pokémon Sun & Moon might have discovered this through a hidden easter egg. There’s a rare chance you’ll find Delibird standing by the fireplace, hinting at a connection between the Pokémon and Santa. Delibird’s skill with chimneys suggests it might even help Santa deliver presents around the world each year.
5. Pokémon’s Hidden Birthday Tribute — Pokémon Diamond & Pearl
There’s a hidden surprise in Pokémon Diamond & Pearl that you can discover on January 12th. On that specific date, if you start the game, the town of Snowpoint City will be covered in a special, sparkly snow called Diamond Dust. This doesn’t change how the game plays, but it’s a tribute to Junichi Matsuda, the lead developer and composer of Pokémon, as January 12th is his birthday. It’s a little easter egg added to honor the person who helped create the whole franchise!
6. Congrats on Time Traveling — Pokémon Omega Ruby & Alpha Sapphire
The Pokémon series strongly encourages collecting, and completing the Pokédex has always earned players a special certificate from the game developers. But fans discovered an extra reward in Pokémon Omega Ruby & Alpha Sapphire: if you put in the effort, you can receive a Time Travel Award. This award is given for transferring a Pokémon all the way from the original Pokémon Ruby & Sapphire games to the remakes. It’s a challenging task, but Game Freak recognizes and rewards players who go the extra mile.
7. Surfing Pikachu Joins the Fight — Pokémon Stadium
Pikachu has had many adorable looks over the years, but the Surfing Pikachu design has become particularly iconic. It’s been featured on trading cards and merchandise, essentially becoming a mascot for the Pokémon franchise. You can even unlock Surfing Pikachu in the Pokémon Stadium game, though it’s a challenging feat! To do so, you must win the R-2 Prime Cup Master Ball Division using the original Pikachu from the Red & Blue games. It requires transferring data and carefully selecting your team, but successfully completing this mission allows you to teach your Pikachu the Surf move, finally giving you the coveted Surfing Pikachu.
8. Pokémon’s Surprising Anime References — Pokémon HeartGold & SoulSilver
Pokémon is a hugely popular video game franchise, but many fans first discovered Pikachu through the animated TV series. The Pokémon anime has been running for decades, and the games HeartGold & SoulSilver include a couple of fun nods to the show. Players can find a Mr. Mime on Route 21, which is a reference to the Mr. Mime that Ash Ketchum’s mother has in the anime. There’s also a hidden detail in Cerulean Gym: if you bring Togepi inside, it will start crying, likely because the gym is the home of Misty, who has a strong connection to Togepi in the show.
9. The Strange Souvenir — Pokémon X & Y
When Pokémon X & Y came out, players quickly began searching for hidden secrets. One of the most mysterious discoveries was a strange hiker who, if approached at his hotel for four consecutive days, would give the player a unique item called the Strange Souvenir. This tiki-like totem puzzled fans, as its purpose wasn’t explained. Years later, when the Alola region was introduced in a newer Pokémon game, the mystery was solved. The Strange Souvenir turned out to be a reference to the Island Guardians of Alola, making it a clever and well-hidden easter egg that impressed players.
10. Lumiose City’s Secret Ghost Girl — Pokémon X & Y
A creepy and mysterious detail hidden in the Kalos region of Pokémon X & Y has fascinated fans for years. Players exploring a building on North Boulevard will find a strange, unnamed girl on the second floor. She suddenly appears behind them and then quickly disappears. This ghostly encounter, along with other unsettling messages found throughout Kalos, remains one of the biggest unsolved mysteries in Pokémon. Nintendo has never explained who the girl is or what she’s doing there, and fans are still debating her origins more than a decade after the game’s release.
