Funny, I barely remember the plot for GSC, and I actually remember RSE's even less. It was that forgettable. :P
Without Mankey, Brock pretty much owns you in yellow as Pikachu and everyone else will be useless against Brock's Geodude and Onix.
If you trade your pikachu to Pokemon stadium, you can get Surf. If you then trade pikachu to Red/Blue and evolve to Raichu there, you can get yourself a surfing Raichu with thunderbolt. That alone makes pikachu better then jolteon or any other electric in the game. And if you have surf on pikachu, you don't need any water types as pikachu can serve as this. Surfing pikachu owns the first 2 Elite 4 members by himself.
and you have to trade to get Machamp
Charmander is next because out of the 3 starters that you can get, it's the easiest to obtain. Bulbasaur requires you to make Pikachu really happy, while Squirtle requires you to beat Lt. Surge first. With Charmander, you just have to speak to him.
By the time you face Erika, you should be close to having Charizard (if you don't already), and can use HM fly. Once you have Charizard, you don't need any other flying type.
Squirtle is easy to replace. Super Rod lets you catch Staryu at Level 40.
A better D/P HM Slave combo is Bibarel (Surf/Waterfall/RockClimb/Cut) and Aerodactyl (Fly/Fog/RockSmash/Str). All 8 of 8 can be used between them and Aerodactyl is easy to dig up underground (although it's probably better to just use some lv2 starly for Fly/Fog Clear and some filler for RockSmash/Str).
I've done no-Pikachu runs in Yellow... now note that my memory may be bubbling over to Red and Blue catching locations... Fetch mankey, nidoran and a spearow. Oddish is enough to handle misty, and helps against Lt. Surge. Course, dugtrio helps a hell of a lot.Pikachu is good early on, and Thunderbolt is pretty amazing obviously, but complete lack of an evolution with such base stats and easily being your most worthless Pokemon against Giovanni's gym (and one of the against Sabrina) is just gay. I'm not even sure with top tier, but sure, he's your only starter so theoretically his level lead just wins.
The thing is about Aerodactyl is that you need the National Dex to get it, and it's hard to find an Old Amber in the Underground. We're talking in-game, and you'll be done with the main story by the time you even get the chance to use it.
Pelipper, on the other hand, is relatively easy to obtain.
Forgot about that, so disregard. I guess you wouldn't really be pressed for space in party anyway since you're only using 2-3 pokemon max.The thing is about Aerodactyl is that you need the National Dex to get it
well i know for a fact, DP
OU
starly
shinx

bronzor
bidoof
bidoor is a HM slave
if you choose him, i'm pretty sure something like 90% of players will keep him on the team
