You defeat all of team rocket at the game corner. If you can't find their hideout go up to the poster to the right of the counter and press A and some stairs should appear to your far right which you should go down and find the rockets hideout.
Head east of Pewter City and follow Route 4 until you reach Mt. Moon at the end of it. Navigate your way through the cave, and you'll eventually end up at Cerulean City, where the next Gym is located.
i say you should look in viridian forest
meet him and beat him
Im guessing your talking about yellow version... so u can either catch a nidoran male or female and level it up until it learns double kick or u jus gotta level up pikachu high enough until its slam actually does some damage to brocks Pokemon
Train and fight him again until you beat him
you have to beat team roket in saffron, lavender and celadon first.(use dark type moves like bite)
cerulean city.good day sir
In the grassy area which is after the town where you beat Brock.
y beat brock at pewter Jim
i say you should look in viridian forest
yes brock lesnar beat nexus
This can actually happen. For example your playing Pokemon yellow and you only have pikachu as a Pokemon, you will not be able to beat brock not matter what level pikachu is, but misty can be defeated because pikachu's electric type moves are strong against water type Pokemon.
after you beat the elite four, you can go to to the Kanto region. (at least i think its Kanto its the one with Brock and misty) at the first city, pewter town, there is a man next to the Pokemon center after you beat Brock he will give you the silver wing (gold version) or the rainbow wing (silver version).
You can catch a grass type Pokemon but catching mankey is the easiest because it appears a lot especially to the east of Pewter (where Brock is). Mankey has the advantage of being a fighting Pokemon which is super-effective against Brock's Pokemon.
Mankey learns low kick at level 9. it's a great way to beat brock.
Pokemon Are Not Evil they just faint the opjectson of the game is to beat the champion in the Pokemon league
No cause alistair overeem beat brock in the first round by TKO
After you've beaten Brock go beat the other six leaders then you can fight Blue
