nobody compares to this old motherfucker right here
this dude's the original roadblock, if he hasn't had his cup of coffee, there's no way in hell you're leaving viridian city, and at his age, being able to isolate an entire city from the outside world is kind of a huge deal
not only that, he also teaches you how to catch a weedle, again and again and again and again, this old man is clearly some kind of unknown master of capturing pokemon, i bet not even mewtwo can stand up to this guy's pokeballs
in addition, if you take one of his pokemon-catching lessons, and then fly to cinnabar island and surf up and down the coast...
something unexpected might happen...
holy motherfuckin shit!!!
clearly this old man of the viridian city has some mystical powers that open up a portal to the forbidden realm, what appears on first sight to be a simple lesson in using pokeballs is actually an ancient summoning ritual that calls forth the most corrupt and mysterious beings, this old man is not just a capturing master, he is also a gatekeeper in all senses of the word
you want to clone your rare candies? talk to the old man
you want to battle weird glitchy trainers? talk to the old man
you want to own the exclusive BIRD pokemon? talk to the old man
you want to do a whole bunch of other weird shit that you'd never thought possible? talk to the old man
that is why in a contest of ultimate NPC, nobody can compare to him and nobody ever will
