i can remember all of them from when i was a kid, but that number has since tripled. if i was a kid now i don't think i would be able to learn all of them in the first place!
If I need to say the names of the pokemons I'll forget something like Tangela, but if I see the image of the pokémon I can remember the name. Things get fuzzy at the same time that I stop watching the anime.
It's the companys fault for looking at the 151 and saying, what if we replaced all this with random bullshit? I miss the og pokemon. I tried playing newer games but damn, it's pure chaos.
Don't worry trainer, you can always get back together in a big ol' group of all your friends and between everyone we'll be able to figure out all their names. :)
I get fuzzy on anything after Black/White. Hisuian and Alolan regionals would probably be my saving grace after that, I never found the will to finish Sword and have had 0 interest in Scarlet/Violet.
After a certain point the Pokemon started being made with the level of creativity and identity you can expect from AI generated garbage, so I don't blame you for forgetting them.
