Brock awaits at the Pewter City gym. Head North from Pallet Town and battle the trainers that are placed. When you get to Pewter City, you'll have to do some things at the museum. After you've done the things the aids need you to do, you can go and battle Brock. He is a rock type Pokemon trainer; to beat him, use grass or water Pokemon. When you have won your badge, go East out of the city and one of Professor Oak's aids will meet you and give you running shoes gifted by your mom in the game.
You can be any level, but it depends on your starter.
Bulbasaur: At least Level 13, when it learns Vine Whip.
Squirtle: As long as it has a water-type move, like water gun. You're fine then.
Charmander: Ooh boy, why? You're going to have trouble beating Brock unless you're at least level 15 or evolved into a charmeleon.
geodude level 12 and onix level 14
level 1
i say you should look in viridian forest
meet him and beat him
Train and fight him again until you 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
Yes.
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.
cerulean city.good day sir
In the grassy area which is after the town where you beat Brock.
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.

In Pokemon yellow your starter is pikachu which dosnt do well against a rock type trainer like Brock my suggestion would be catch a nidoran (male) or (female) "which ever seems more legit to you, then you need to train it to level 12 when it learns double kick. after it learns the move i recommend train it 2 more levels then battle Brock, it will be a piece of cake
Mankey learns low kick at level 9. it's a great way to beat brock.
After you've beaten Brock go beat the other six leaders then you can fight Blue
