The Unknown Hype
The One
you were pretty much putting the game on hard mode until you found some better pokemon. plus that yellow version back in the day was bullshyt with that pikachu that never wanted to take a thunderstone

picking a fire pokemon (Charmander on the OG Red/Blue) was probably the hardest, you were trash facing Brock and Misty back to back. Once Charmander evolved though 
Leaf was easy mode.
Squirtle was easy mode nikka
bulbasaur was so shytty to me I can see how he would be good against the first bosses but later on leaf was just so weak in general. I could deal with the fire and water cuz the damage was good and they looked cool. oh and
at yellow making me have to actually go and train a bug pokemon to get passed the first gymCHIKARITA WAS WOAT GRASS TYPEI only lasted about 1 day with chikarita in crystal.

but yeah, you pretty much had no choice but to train Caterpie to a Butterfree for that Confusion. As soon as I beat Brock, Butterfree's wack ass was thrown in the PC bushes
